Note. All reported scores are standard scores except for the CTOPP Elision, CTOPP Blending, CTOPP Rapid Letter Naming, GORT Fluency, and GORT Comprehension subtests. These scores are scaled scores with a M = 10 and a SD = 3. Additionally, the norms used to compute the standard/scale scores for the Peabody Individual Achievement Test, TOWRE Sight Word Efficiency, TOWRE Phonemic Decoding, CTOPP Elision, CTOPP Blending, CTOPP Rapid Letter Naming, GORT Fluency, and GORT Comprehension do not include the age ranges of our participants. These scores, therefore, were computed with the following ages (as appropriate): PIAT-22 years; TOWRE- 24 years; CTOPP-24 years; GORT-18 years, which were the oldest ages in which these tests had normative data available.

^*277 = the number of participants who attended through midpoint assessment; 256 = the number of participants who received posttest assessments, 198=the number of participants who met our minimal attendance requirement and therefore included in this data analysis.
