Note. CELF = Clinical Evaluation of Language Fundamentals, 4th ed. (RS = Recalling Sentences); CASL = Comprehensive Assessment of Spoken Language (GJT = Grammatical Judgment subtest); PPVT = Peabody Picture Vocabulary Test, 4th ed.; SARA = Study Aid and Reading Assessment; TOWRE = Test of Word Reading Efficiency (SWE = Sight Word Efficiency, PDE = Phonetic Decoding Efficiency); FCAT = Florida Comprehensive Assessment Test; GMRT = Gates-MacGinitie Reading Test. Developmental scale scores were used for the FCAT and GMRT; in the absence of developmental scale scores, standard scores were used for the CASL and PPVT-4; due to the unavailability of developmental scale or standard scores, total correct raw scores were used for CELF-4, TOWRE-2, and SARA measures.
