Overview
The Gray Oral Reading Test – Fifth Edition (GORT-5; Wiederholt & Bryant, 2012) is an individually-administered, norm-referenced instrument used to measure oral reading fluency and comprehension. It yields an Oral Reading Index composite score. Additionally, it includes a system for performing an analysis of reading errors or miscues. As an aid in the diagnosis of oral reading difficulties, it is intended for individuals aged 6 years through 23 years,11 months.
The GORT-5 was designed to (a) help identify students significantly below the appropriate level in oral reading ability and those who may benefit from interventions; (b) aid in identifying a student’s strengths and weaknesses; (c) document reading progress as a result of specific reading interventions; (d) serve as a research tool in measuring the reading abilities of school-aged children; and (e) help to diagnose reading disabilities.
Summary
Age: 6 years to 23 years 11 months
Time to Administer: 20-30 minutes
Method of Administration: Individually administered, norm-referenced measure of reading rate, accuracy, fluency, and comprehension.
Yields standard scores (M = 100, SD = 15), percentile ranks, and age and grade equivalents. Has two equivalent form.
Subscales: Overall Composite: Oral Reading Index
Index Scores: Rate, Accuracy, Fluency, Comprehension
Autism Related Research
None found. However, the test authors (Wiederholt & Bryant, 2012) reported Cronbach’s alpha reliability coefficients for GORT-5 Comprehension scores range between .90 and 96 in the normative sample, .97 in an ASD subsample, and .97 in an ADHD sample. With regard to GORT-5 Accuracy scores, Cronbach’s alpha coefficients ranged between .85 and .94 in the normative sample, .93 in an ASD subgroup, and .95 in an ADHD subgroup.
