Abstract

Graduate Records Examinations (GRE) remain an important criterion for admission to the graduate program. This study explored the predictive role of the GRE for college success among deaf students because most deaf and hard-of-hearing students experience lifelong difficulties in English language and literacy because of their different language acquisition processes. Additionally, the study examined the students' undergraduate grade point average (UGPA), first-semester grade point average (FSGPA), and graduating graduate grade point average (GGPA) to understand D/HH students' performance in a graduate program. Additionally, the study examined the use of the Wechsler Adult Intelligence Scale (WAIS) as a substitute for the GRE criterion for graduate admission. The findings' discussions offer suggestions for using GRE scores in admitting D/HH students to graduate academic programs across the United States.

Keywords: GRE, GPA, WAIS, Deaf and Hard of Hearing, Teacher Preparation


Most graduate programs use the Graduate Records Examinations (GRE) scores to identify and admit candidates considered academically ready for graduate-level learning and less likely to struggle academically (Education Testing Service (ETS), 2019). The argument for using GRE as a program entry is that it provides an objective measure that applies to all candidates as opposed to other entry requirements, which may be subjective. ETS does not support a cut-off score based on only GRE scores as a sole criterion for denial of admission (ETS, 2019). According to ETS (2019), the three critical skills assessed in GRE needed in graduate programs include Analytical Writing, Verbal Reasoning, and Quantitative Reasoning. Verbal Reasoning focuses on how well an individual understands and can analyze, evaluate, and synthesize written information. Quantitative Reasoning examines one's mathematical skills, including arithmetic, algebra, geometry, and data analysis. Finally, Analytical Writing assesses an individual critical thinking and analytical writing skills. To demonstrate the three skills in GRE requires one to have a good command of English which is the language used in the assessment.

Opponents of the use of GRE as an entry requirement argue that GRE can undermine and underestimate the academic performance of minority groups, thus limiting their access and admission to graduate Education (Abedi, 2002; Ansell et al., 2018; Milner et al., 1984; Stricker, 2004; Stricker & Rock, 1995). According to Abedi (2002), most minority students, particularly English Language Learners (ELLs), have limited resources to learn the test material. Hence, ELLs tend to score lower when compared to English proficient peers (Abedi, 2009, 2014). Research noted that ELLs faced challenges with the large-scale standardized test (Abedi et al., 2002; Benet et al., 1985; Noble et al., 2014; Ragosta & Kaplan, 1986; Stricker, 2004). In particular, Stricker (2004) observed a challenge of using and interpreting English assessments to compare and admit both native English users and English language learners (ELL). Also, previous research show gender gap in the GRE performance which would impact the admission of female students in some graduate programs (Tock & Ericsson, 2019). The limitation presented regarding minority indicates a need for alternative documentation platforms that allow candidates to show attributes such as perseverance, creativity, and conscientiousness during interviews, exhibitions, or portfolios of their work. Alternative documentation includes letters of recommendation, personal statements, and GPA from previous course work from an accredited university.

D/HH students' group is one of the minority groups that GRE can undermine and underestimate their academic performance, thus limiting their access and admission to graduate education. Most D/HH students are not native English speakers and are ELLs. In addition, most D/HH students struggle with reading and writing English because of language delay or language deprivation they experience because most of them have non-signing hearing parents (Hall et al., 2017; Hile, 2009; Meek, 2020). As a result, most D/HH students arrive at school with limited language for learning and literacy development (Erting, 2001; Erting & Pfau, 1997). Due to language challenges, research shows that their reading by the time most D/HH students graduate high school reading below the fourth-grade level, and only 7–10% of D/HH high school graduates read at the seventh-grade level or above (Allen, 1986, 1994; Cawthon, 2004; Holt, 1994; Marschark et al., 2002; Strong & Prinz, 1997; Traxler, 2000; Wilbur, 2000). Also, research shows that D/HH students' math performance is lower than expected from grade-level hearing peers (Kritzer, 2009; Marschark et al., 2015; Mitchell, 2008; Traxler, 2000). Although research is lacking that focus on D/HH students' performance on GRE, there is little research on individuals with disabilities who have taken ETS standardized exams.

ETS Standardized Exams and Individual with Disabilities

According to ETS, individuals with disabilities receive testing accommodations, including extended time, extra breaks, screen magnification, and screen readers. The accommodation varies depending on the individual test taker's needs. There is limited research on GRE and individuals with disabilities (Ling et al., 2020). Ling et al. (2020) examined the validity of using the GRE General Test to assist with graduate school admissions for individuals with disabilities. They found no significant impact on the First-semester Graduate Grade Point Average (FGGPA), although it varied across various disabilities. Previous research that has focused on students with disabilities in standardized testing focuses on Scholastic Assessment Test (SAT) and reports challenges that vary across disabilities and the age of the onset of the disability (Benet et al., 1984; Braun et al., 1986; Ragosta & Kaplan, 1986; Ragosta & Nemceff, 1982). For instance, the correlation between Undergraduate Grade Point Average (UGPA) and SAT scores was lower for test-takers with a learning disability (Laitusis et al., 2002).

Previous studies have demonstrated that across all disabilities, D/HH students' performance was the lowest score in standardized testing (Benet et al., 1985; Jones & Ragosta, 1982; Ragosta & Nemceff, 1982). In most cases, the language of assessment was English, and most D/HH have low English literacy skills of D/HH students, which impacts their performance in the assessments (Luetke-Stahlman & Nielsen, 2003; Qi & Mitchell, 2012). Ragosta and Nemceff (1982) examined D/HH students' performance on SAT and reported that their scores were lower than those of students without disabilities (between 0.5 and 1.2 standard deviations). These findings concur with Benet et al. (1985), who reported that D/HH students scored lower than other groups with disabilities and students without disabilities by at least 0.5 standard deviations. D/HH students performed below the general test takers population on the verbal portion of the SAT (Benet et al., 1984, 1985; Jones & Ragosta, 1982; Ragosta & Kaplan, 1986). Mitchell and Cawthon (2014) questioned the 'fairness' and 'bias' of assessment tools and argued that "the performance differences that establish bias, by themselves, do not mean that a test is unfair. Bias only becomes unfairness when the reason for the differences is unrelated to the content of the test" (p. 2).

Research with D/HH students who are ELL reported difficulties related to vocabulary use, reading comprehension, and the quantity of the reading materials ((Luetke-Stahlman & Nielsen, 2003; Ragosta & Kaplan, 1986). D/HH students' performance on assessments varies with the diversity of demographic, age of hearing loss, the type of assessment, and educational placement (Braun et al., 1986; Cawthon, 2015a, b). Jones and Ragosta (1982) noted no differences in verbal scores of D/HH students based on their degree of hearing loss, but discrepancies occurred in the age of onset of hearing loss. Benet et al. (1985) found that D/HH students performed better on mathematical tests than verbal tests compared to non-disabled students. The correlational study by Jones and Ragosta (1982) reported a relationship between freshman GPA scores and SAT scores for 60 D/HH students. Also, they noted that combined high school GPA and SAT predicted freshman performance of D/HH students. Also, within the D/HH student population, Jones and Ragosta (1982) reported that pre-lingual D/HH students performed lower in SAT than post-lingual D/HH. Pre-lingual D/HH is an individual who becomes D/HH before language acquisition and development. On the other hand, post-lingual D/HH is an individual who becomes D/HH after acquiring and developing language.

Predictability of GRE in Graduate Education

In some graduate programs, GRE and UGPA are valid predictors of most graduate performance indicators (Kuncel et al., 2001). Despite this, studies have inconsistent findings and conflicting opinions on the GRE's ability to predict graduate performance (Kuncel et al., 2001). The ETS, which funds a considerable amount of research on the validity of the GRE, asserts that GRE General Test scores tend to show moderate correlations with first-year GPA averages (ETS, 2019). Several programs have argued for considering both UGPA and GRE scores. For example, McKee et al. (2001) reported that both UGPA and GRE scores predicted Graduating-semester Grade Point Average (GGPA) for master students in criminal justice. UGPA alone accounted for about 24% of the variance in GGPA, while (Graduate Records Examinations- Verbal) GRE-V explained the most variance (9.9%), Graduate Records Examinations-Analytical writing (GRE-A) (8.9%), and Graduate Records Examinations- Quantitative (GRE-Q) (6.9%). A total of 40% of the variance in GGPA was accounted for by the combination of UGPA and GRE scores.

Studies across various disciplines have indicated that GRE can be a predictor of 1st year GPA of graduate students (Holt et al., 2006; Powers, 2004; Sternberg & Williams, 1997). Powers (2004) reported that GRE scores and (UGPA) predicted 1st year GPAs of veterinary medical graduate students. Sternberg and Williams (1997) examined the predictive validity of the GRE for students in a graduate psychology program. They reported that GRE scores predicted students' GPA for the 1st year but not the 2nd year. Holt et al. (2006) indicated that GRE scores predicted students' first year and cumulative GPAs of master students in an engineering program. Their findings showed that both GRE-V and GRE-Q scores explained a significantly large portion of the variance than undergraduate GPA.

Previous studies have examined the predictive ability of GRE scores to graduate exit exams. For example, Schmidt et al. (2009) study on counseling graduate students found that UGPA, GRE-V, and GRE-Q scores predicted students' performance on the comprehensive exit examination. Of the three scores, GRE-V was the best predictor. Similarly, Stack and Kelley (2002) also studied the validity of GRE scores for master students in criminal justice. They reported that GRE-V was the better predictor of GGPA and accounted for 21% of the variance in GGPA. Another study reported both GRE scores and UGPA as strong predictors of academic performance, such as final GGPA, students' low grades, and incompletes (Reisig & DeJong, 2005).

On the other hand, various studies have shown that GRE does not predict students' GGPA and graduate education success (Feeley et al., 2005; Moneta-Koehler et al., 2017; Sternberg & Williams, 1997). Sternberg and Williams (1997) found that GRE was limited in predicting students' success in graduate school for psychology. According to Sternberg and Williams (1997), only the analytical subtest predicted any aspect of graduate success beyond the first-year GPA based on gender. She noted that the verbal subtest predicted only the first-year GPA. Feeley et al. (2005) examined the validity of GRE scores in predicting GGPA for students majoring in communication. They found that the UGPA was a better predictor of GGPA than the GRE for both masters and doctoral students. More recently, Moneta-Koehler et al. (2017) demonstrated that scores on the GRE are not predictive of success in biomedical graduate school. They reported a correlation between GRE and FSGPA. Hence, the literature review indicates inconsistencies in the ability of the GRE to predict graduate school students' performance. The literature review shows that GRE scores and UGPA have been used as one of the criterion admissions tests to predict graduate performance. The review does not mention D/HH students, hence the assumption that previous studies geared toward hearing candidates or students. Thus, more research was needed to address the gaps in previous graduate studies' entry requirements for D/HH students. The present study, therefore, tested the difference in the predictive validity of GRE scores between D/HH students and hearing students enrolled in a graduate program. In addition, the study considered the hearing loss and language issues prevalent among D/HH candidates in examining the predictive validity of GRE scores of hearing and D/HH students pursuing a masters in Deaf Education.

Methodology

Study Design and Data Collection

The current study focused on quantitative data drawn from the university's registrar databases that hold the applicants' Admission GRE scores, WAIS level, UGPA scores, FSGPA scores, and GGPA scores. The current study focused on graduate students who applied and pursued a deaf education graduate program. The minimum required UGPA for the program is 3.0. Although applicants are required to take GRE, there is no required standard score. For GRE, the students submitted three scores: Quantitative, Verbal, and Total.

Until recently, D/HH applicants were allowed to substitute GRE with the Wechsler Adult Intelligence Scale level (WAIS) for graduate admission. Hence, some D/HH applicants took WAIS while others opted for the GRE test. WAIS assessed the cognitive ability of adults by examining the relationship between intellectual functioning and memory for purposes of educational planning and placement (Climie & Rostad, 2011; Hershberger, 1997). The faculty argued that WAIS was an alternative fair test for D/HH students to overcome biases and challenges of language and literacy expectations of the GRE that D/HH students experienced. However, there were no scores for students who took the WAIS assessment. The psychologist interpreted the performance and assigned the candidates a qualification that used the words superior, high average, average, and low average; hence it was impossible to perform a quantitative analysis of the WAIS data. Applicants admitted to the graduate program had the labels superior and high averages.

Hence, data analyzed in the current study included GRE scores, WAIS level, First Semester GPA (FSGPA), and Graduating GPA(GGPA) for students who enrolled in the graduate program in Deaf Education from 2007 to 2018 to predict graduate student success. The grade point average measured graduate student success (GPA) scored after the first semester and at the end of the program. The university's student application records and transcripts provided the data. Data analysis included descriptive statistics means and standard deviations. Inferential statistics employed a t-test to compare D/HH students' and hearing peers' performance in the GRE. Also, the Pearson correlation determined the relationship between GRE scores, undergraduate GPAs, and graduating GPAs. Finally, the multiple regression determined the best predictor for both D/HH students and hearing students' achievement (GGPAs) in the master's program.

Participants

A total of 111 students' data was analyzed. Table 1 presents the descriptive results. The participants are graduate students from a program that implements an ASL/English bilingual philosophy intending to increase the population of teachers who are D/HH and from culturally and linguistically diverse backgrounds. Of the total number of students in the program, 67.6% were D/HH. Hence, the program's recruitment and retention strategy intentionally target D/HH students, resulting in a rare high number of D/HH students graduating from the program. The term D/HH represents students' self-identity as Deaf or Hard of hearing. All D/HH in the program identified themselves as ASL/English bilinguals. Also, Table 1 shows that most students were White (73.9%) and female (70.3%).

Of the total 111 students, some did not have data on all the variables considered in the study. All students had UGPA. Some students with GRE or WAIS level and UGPA had missing FSGPA and GGPA scores. Students who missed FSGPA scores (26 students) were admitted into the program, enrolled, and withdrew before completing the first semester due to financial or other personal challenges. Also, other students did not have the graduating GGPA because they dropped out of the program before graduating. Table 1 shows that 41 of the 111 students did not have GGPA. The absence of the GGPA was because graduate students had to pass the teacher licensing exams to do internships and graduate. Some students could not pass the teacher licensing exam, and despite being offered an option to complete a master thesis instead of the teaching certification, they could not complete the thesis; hence they did not get the final GGPA. Most of the students who dropped out (in-completers of the program) were D/HH (37 D/HH and four hearing students). Also, of these 37 D/HH students, nine were Hispanic, three black, and 25 were White.

Hence, the results of each research question drew on different groups of students who had complete data for the question. For example, on the question on GRE predictability on the graduating GGPA, the analysis was conducted using data for only the students with GRE, UGPA, FSGPA, and GGPA scores.

Purpose of the Study

The study aimed to examine and compare the predictive ability of the GRE scores on the D/HH students and hearing students' outcomes in the master's in Deaf Education. During COVID-19, most graduate programs decided to offer a complete waiver or a temporal waiver of the GRE due to concerns and barriers associated with taking the online GRE at Home (Millar, 2020). Even before the pandemic, more graduate applicants are looking for schools that do not require GRE, and an increasing number of universities are joining the "GRExit" movement (Jaschik, 2016). The "GRExit" movement does not require GRE as part of the graduate application. Additionally, in the recent past, all D/HH students are required to take GRE and not WAIS. Currently, no research explains the WAIS and GRE use as part of entry requirements and the student's success.

Moreover, several D/HH applicants question the termination of WAIS and the requirement for GRE for both hearing and D/HH applicants. Consequently, the researchers sought to examine if GRE was a predictor of graduate student success and use the findings to make recommendations. Additionally, the researchers wanted to compare students' performance and academic success concerning WAIS and GRE to recommend whether the WAIS assessment was essential as a prerequisite for joining a graduate program for D/HH students.

Research Questions

The present study, therefore, focused on two major questions:

  1. What is the difference in the predictive validity of GRE scores between D/HH students and hearing students enrolled in a graduate program?

  2. How does hearing loss and language issues prevalent among D/HH candidates affect the predictive validity of GRE scores when pursuing a masters in Deaf Education in comparison to their hearing peers?

The research questions were organized in three parts to examine the students' application and admission, performance at the program's start (first semester), and performance at the end of the program (graduating semester). This article responded to the following research questions:

Students' Application and Admission

  1. Is there a significant difference between D/HH and hearing students' GRE scores?

  2. Is there a significant difference between D/HH and hearing students' UGPA scores?

  3. Is there a correlation between GRE scores and UGPAs across all students and separately for D/HH students?

Start of the Programs

  1. Is there a significant difference in the mean of first-semester graduate GPA(FGPA) for D/HH and hearing students?

  2. Is there a significant difference in the mean of first-semester graduate GPA(FGPA) for D/HH who took the GRE and those who took WAIS?

  3. Is there a correlation between first-semester graduate GPA and GRE score – across all students and separately for D/HH and hearing students?

  4. Is there a correlation between First Semester Graduate GPA and UGPA – across all students and separately for deaf and hearing students' GPA?

End of the Program

  1. Is there a significant difference in the mean of graduating GPA (GGPA) for D/HH and hearing students?

  2. Is there a significant difference in the mean of graduating GPA (GGPA) for D/HH who took the GRE and those who took WAIS?

  3. Is there a correlation between graduating GPA and GRE scores?

  4. Is there a correlation between graduating GPA and undergraduate GPA?

  5. Is there a correlation between graduating GPA and first-semester graduate GPA?

  6. What is the best predictor for students' achievement in the master's program in Deaf education?

Results

The normality of the data was checked and determined as normally distributed or approaching normality using the Shapiro-Wilks test and the Normal Q-Q plots. Data analysis answered the research questions (RQs) of interest. The analysis followed a timeline matching the students' progression through the program to provide more clarity to the reader. The three-time levels included the application process, the program's start, and the program's end.

Program Application and Admission

The research questions that guided the first part of the application process included:

RQ1: Is There a Significant Difference Between D/HH and Hearing Students' GRE Scores?

All the applicants submitted only the Quantitative and Verbal portions of the GRE test. We converted some students' old GRE scores into new GRE scores. Here is the table from ETS for converting Old to new scores.

https://www.qsleap.com/gre/resources/old-gre-to-new-gre-score-conversion

In answering this question, an independent samples t-test examined significant differences in GRE Quantitative, GRE Verbal, and GRE Total scores. The results showed a significant difference between D/HH students and hearing students in all GRE scores. Hearing students performed significantly better than Deaf students on all the GREs required to enter the program. The total GRE for hearing students (M = 291.5, SD = 9.96) was better than D/HH students (M = 281.93, SD = 11.89), t (64) = 3.56, p = .001 (See Table 2).

RQ2: Is There a Significant Difference Between D/HH and Hearing Students' UGPA Scores?

An independent-samples t-test compared UGPA for D/HH students and hearing students. The results showed there was a significant difference in UGPA scores for D/HH (M = 3.11, SD = 0.42) and hearing (M = 3.39, SD = 0.34); t (109) = 3.62, p < .001. The hearing students had significantly higher UGPA than D/HH students (see Table 3).

RQ3. Is There a Correlation Between GRE Scores and UGPAs Across All Students and Separately for D/HH Students?

  1. A Pearson Correlation assessed the relationship between GRE scores and undergraduate GPAs – across all students. The results, as shown in Table 4, indicate that:
    1. There was a significant relationship between GRE Total scores and total UGPA scores (r = .282, p = .024).
    2. There was a significant relationship between GRE Total scores and GRE Quantitative scores (r = .775, p < .001).
    3. There was a significant relationship between GRE Total scores and GRE Verbal scores (r = .921, p < .001).
    4. There was a significant relationship between GRE Quantitative scores and GRE Verbal scores (r = .468, p < .001).
    5. There was no significant relationship between UGPA and GRE Verbal scores (r = .243, p = .053).
    6. There was a significant relationship between UGPA and GRE Quantitative scores (r = .249 p = .047).
  2. A Pearson Correlation was computed to assess the relationship between GRE scores and undergraduate GPAs for hearing students. For hearing the students, the results showed a significant relationship between all GRE scores and UGPA except UGPA and GRE Quantitative scores (see Table 5).

  3. A Pearson Correlation was also computed to assess the relationship between GRE scores and undergraduate GPAs for D/HH students. For D/HH students, the results showed that the UGPA did not correlate with GRE Total, GRE Quantitative, and GRE Verbal scores (see Table 6).

RQ4. Is There a Significant Difference in the Mean of First-Semester Graduate GPA (FGPA) for D/HH and Hearing Students?

An independent-sample t-test compared FGPA for all D/HH students and hearing students. The results did not show any significant differences in students' first-semester GPA scores. That is, D/HH students (M = 3.64, SD = .55) performed about the same as hearing students (M = 3.71, SD = .49), t (83) = .532, p = .596.

RQ5. Is There a Significant Difference in the Mean of First-Semester Graduate GPA (FGPA) for D/HH Who Took the GRE and Those Who Took WAIS?

The D/HH students' sample included both students who took GRE and the WAIS test. An independent-sample t-test compared FGPA for D/HH students who took GRE and D/HH students who took the WAIS test. The results did not show significant differences in the students' first GPA scores. That is, for D/HH students who took GRE (M = 3.78, SD = .32) performed about the same as D/HH who took WAIS (M = 3.58, SD = .61), t (57) = .1.26, p = .213.

RQ6. Is There a Correlation Between First-Semester Graduate GPA and GRE Score – Across All Students, and Separately for D/HH and Hearing Students?

  1. Correlation across all students

    A Pearson Correlation assessed the relationship between GRE scores and Semester 1 GPAs for all students. There was a low negative correlation between Sem 1 GPA scores and GRE Quantitative scores for all students. The findings suggest that students' Semester 1 GPA scores were high even for those with low GRE Quant GRE Quantitative scores (see Table 7).

  2. Correlation between D/HH students

    Similarly, a Pearson Correlation assessed the relationship between GRE scores and Semester 1 GPAs for D/HH students. There was no significant correlation between Semester 1 GPA and GRE scores (GRE Total, GRE Verbal & GRE Quantitative) for D/HH students. The findings showed that D/HH students had high Semester 1 GPA scores even when admitted with low GRE scores (see Table 8).

  3. Correlations between hearing students

    A Pearson Correlation assessed the relationship between GRE scores and Semester 1 GPAs for hearing students to compare the results. The results showed a negative correlation between Semester 1 GPA and GRE Quantitative scores for hearing students. The findings indicated that hearing students' Semester 1 GPA can be high even for students with low GRE Quant. Hearing students' performance in Semester one had an impact compared to their entry GRE Quantitative scores. The finding indicated that student performance in the first semester in graduate school contributed to them graduating early and with higher GPAs even when their total GRE scores were low. D/HH students' data did not demonstrate this finding (Table 9).

Discussion

The current study occurred in a university graduate program that adopts an ASL/English approach and ensures communication and language access to both hearing and D/HH students. All students and faculty are required to be proficient and use ASL as the language of instruction. Comprehensible language access allowed D/HH students communication and social interaction opportunities in and out of the class sessions. Most applicants who demonstrate the required proficiency skills in ASL tend to be individuals who are D/HH who are ASL users. Hence, the descriptive statistics indicated a high percentage of D/HH students compared to hearing students. In this section, the discussion will highlight the key findings based on the research questions.

Most deaf applicants' GRE scores in this study were significantly low, indicating that GRE may not be an accurate assessment for the decision to enroll Deaf applicants to graduate school or even to assess their success in graduate studies. ETS (Educational Testing Services, 2008) reported that minority students typically received significantly lower GRE scores which may explain the Deaf applicants' scores as a minority group. Specifically focusing on Deaf as a student with disabilities, there is limited research on GRE and students with disabilities, and most of the studies that focused on testing college entry exams such as GRE and SAT taken by applicants with disabilities occurred almost 40 years ago (Benet et al., 1984; Benet et al., 1985; Braun et al., 1986; Ragosta & Kaplan, 1986; Ragosta & Nemceff, 1982). A more recent survey examined the predictive ability of GRE scores for graduate students with disabilities compared to those without disabilities (Ling et al., 2020).

The current study concurred with the previous research findings that there was a significant difference between students with disabilities and those without disabilities. Ling et al., (2020) showed that the significant difference between students with and without disabilities was on GRE Quantitative but not for GRE Verbal and GRE Analytical Writing. Ragosta and Nemceff (1982) reported on the differences in the performance of D/HH and non-disabled students on SAT. D/HH students had lower scores compared to their non-disabled peers. Ling et al. (2020) and Ragosta and Nemceff's (1982) studies did not provide information on Deaf participants' hearing level and the mode of communication, whether spoken or sign language.

Separating scores in GRE-V and GRE-Q in the analysis between different subgroups in this study enabled the researchers to understand the unique characteristics of D/HH students and hearing students' performance on the test. The difference was apparent in GRE-V, which requires a high level of English proficiency (Educational Testing Services, 2013). The low performance on GRE-V is similar to the findings reported on SAT, in which D/HH students reported difficulties related to vocabulary use, reading comprehension, and the quantity of the reading materials (Ragosta & Kapla, 1986).

Previous research on standardized testing indicates that D/HH students experience challenges that can impact their performance because most testing lack accommodation for language delay and competence (Cawthon, 2011, 2015a, b; Cawthon & Leppo, 2013; Luft, 2020; Qi & Mitchell, 2012). According to Qi and Mitchell, testing D/HH in a spoken language such as English impedes their ability to articulate their content knowledge. Cawthon (2011) argued that when it comes to assessment and DHH students, the main issues include access to the test content, maintaining the test score validity, and D/HH students' linguistic and communication needs. In most cases, standardized testing, including GRE, and accommodation of extended time, does not explicitly address the limited background in the test and the D/HH students' language and communication needs (Cawthon, 2011). Similar to other standardized tests, deaf students' performance in GRE compared to their hearing peers may be explained by their language challenges and access to the content.

The current study showed no significant correlation between D/HH students' GRE quantitative scores and GRE verbal scores. This finding is inconsistent with previous research, which indicated that D/HH students performed low in the verbal section and had higher scores in the mathematical section (Benet et al., 1985; Ragosta & Kaplan, 1986). Also, Ling et al. (2020), reported that D/HH performed better in GRE Verbal than in GRE Quantitative. Previous studies on D/HH students' performance in SAT scores explain that this inconsistency can be due to students' educational placement (Braun et al., 1986). Most participants in the current study attended an educational program for D/HH students in K-12 and at the college level, which provided them with direct access. Cummins's (1991) language interdependence hypothesis posits that language and literacy skills learned in the first language could be transferred to the second language. Based on Cummins (1991), we can assume that D/HH students in this study transferred their ASL language skills into understanding English skills used for the GRE assessment.

Although Deaf and hearing students' data showed a significant difference in their GRE performance and UGPA the data showed no significant difference between D/HH students and hearing students in their first-semester Graduate GPA and graduating GPA. Previous studies on undergraduates did not cite academic performance, but D/HH students identified communication and social issues as the main block in their education completion (Foster et al., 1999; Saur et al., 1987; Stinson et al., 1996). Communication and social issues can result in a 25% graduation rate reported for D/HH undergraduates in the United States (Lang, 2002; Stinson & Walter, 1992, 1997). The graduate students who participated in the current study did not express communication and social issues because they had access to both ASL and English for social and academic use. In addition, most of the students in the program were D/HH students.

The Pearson correlation coefficients indicated no significant relationships between GRE scores and GGPA but showed a negative correlation to the First semester GPA. First, the findings were consistent with previous findings on the predictive ability of GRE that also found that GRE was not a strong predictor of graduate performance (Feeley et al., 2005; Kuncel et al., 2001; Moneta-Koehler et al., 2017; Sternberg & Williams, 1997). Also, the current findings concur with Braun et al. (1986). They reported that SAT scores for high school Deaf students had little to no correlation to their college education although the SAT scores over-reported correlation to all other students with disabilities on their performance in college. On the other hand, the current study found that students First semester GPA accounted for more than 50% of the variance in GGPA. Previous studies have reported the predictability of UGPA to GGPA (Feeley et al., 2005; Ling et al., 2020). Other studies indicated that the combination of GRE scores and UGPA strongly predicts graduate GGPA (Burton & Wang, 2005).

In conclusion, although GRE is a standardized test designed to determine the academic potential of graduate students and is widely used in graduate admission decisions by many universities and institutions in the United States, it was not a predictor of D/HH students' graduate academic performance. Also, with the mixed findings on the predictability of GRE, there is a demand for higher education institutions to be more conscious when making graduate admission applications for students with disabilities, particularly Deaf.

Limitations of this Study

There are three main limitations of this study. The first limitation is that this study targeted candidates in a unique Deaf Education program that embraced an ASL/English bilingual approach. Due to the nature of the program, most students are D/HH and previously attended a special school for the D/HH in K-20, where they had access to a comprehensible language. Participants with diverse backgrounds may provide representative results in the performance of the GRE by D/HH students and an explanation of the validity of the GRE for D/HH students seeking admission to a graduate program. Hence, the generalization of the findings of this study to other disciplines should be made cautiously, with careful consideration given to D/HH students' language access and use.

The second limitation concerns the sample size and available data used in the analysis. Some participants did not have data on all the variables considered in the study. For example, all the participants had GRE or WAIS levels and UGPA scores. However, some participants did not have FGGPA and GGPA. Hence, the results of each research question align with the different data sets drawn from groups of students who had complete data for a particular question.

The third limitation is the absence of a complete GRE data set; The GRE includes three parts GRE Quantitative, GRE Verbal, and GRE Analytical Writing. In the current study, the applicants did not submit scores on GRE Analytical writing. The graduate program performed its writing assessment for the applicants and destroyed the writing assessment scripts upon admission. Also, the qualitative interview committee writing assessment rubric labeled applicants' writing as average, above average, excellent or unacceptable.

Implications and Recommendations for Future Research

This study has some implications to policy on graduate admission decisions for Deaf Education programs and graduate programs admitting D/HH students. First, the study provided means for GRE scores for D/HH and hearing students, which can guide decisions on possible cut-off scores for admission into the Deaf Education program. Also, there is a need of a policy that guide institutions of higher education to be aware of D/HH applicants' low performance on GRE compared to their hearing peers when making decisions on cut-off points so as not to blindly compare them with their hearing peers.

Additionally, since GRE was not a good predictor for graduating GGPA; hence, there is a need for caution when using it to decide on graduate admission to a Deaf Education program. For example in Fall 2020, in the midst of the COVID-19 pandemic, Graduate students were admitted without GRE. Alternative entry requirements such writing sample and interviews used supplemented the absence of the GRE scores. These students progressed well and are now graduating to work in schools as teachers of D/HH students. Hence, the findings from this study call for higher education institutions to consider alternative requirements for D/HH students' admissions into graduate school in addition to the GRE scores if used. With all the findings reported on the relationships between GRE, UGPA, FSGPA, and GGPA, there is a need for a tool that focuses on assessing D/HH applicants' academic ability to pursue graduate school, particularly in teacher education.

Deaf Education graduate programs should re-evaluate requiring GRE scores as part of their admission criteria or use it as the only criterion to admit or not admit. Instead, they should design other forms of admission assessment to supplement the GRE scores. For example, the current study missed scores on GRE Analytical writing not previously collected as part of the criteria. Writing is a challenge for many D/HH students (Antia et al., 2005; Mayer & Trezek, 2019); hence it is important to know the writing ability of Deaf college applicants. More practical entry assessments suggested may include an interview with the admission committee, a written personal statement, an applicant e-portfolio, a sample publication, ASLPI testing, and a detailed resume exhibiting students' previous work and achievement in the field of Deaf Education.

The current data is quantitative; hence, conducting a qualitative will help the field of Deaf education to understand D/HH individuals' experience taking GRE. Also, future studies should examine how variables such as D/HH applicants' previous education placement, high school SAT scores, and language and communication choice may impact their GRE and GGPA. Additionally, future studies ought to examine the challenges graduate D/HH students experience as they pursue their graduate studies.
