This revised version of the popular GORT-3 provides all new normative data. The GORT-4 provides an efficient and objective measure of growth in oral reading and an aid in the diagnosis of oral reading difficulties. The test consists of two parallel forms, each containing 14 developmentally sequenced reading passages with five comprehension questions and can be given to students ages 6;0 through 18;11. The GORT-4 provides examiners with a Fluency Score derived by combining the reader’s performance in Rate (time in seconds taken to read each passage) and Accuracy (number of deviations from print made in each passage). The number of correct responses made to the comprehension questions provides examiners with an Oral Reading Comprehension Score. Report all four scores as standard scores, percentile ranks, grade equivalents, and age equivalents. Combine the Fluency Score and the Oral Reading Comprehension Score to obtain an Oral Reading Quotient.
