The widely used and popular Gray Oral Reading Tests-Third Edition (GORT-3) has been revised and all new normative data provided. 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 that is 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. All four scores are reported in terms of standard scores, percentile ranks, grade equivalents, and age equivalents. The Fluency Score and the Oral Reading Comprehension Score are combined to obtain an Oral Reading Quotient.

The GORT-4 was normed on a sample of more than 1,600 students aged 6 through 18. The normative sample was stratified to correspond to key demographic variables (i.e., race, gender, ethnicity, and geographic region). The reliabilities of the test are high; all average internal consistency reliabilities are .90 or above. The test-retest study was conducted with all ages for which the test can be administered and illustrates the stability and reliability of the measure. The validity is extensive and includes studies that illustrate that the GORT-4 can be used with confidence to measure change in oral reading over time.

Several improvements were made in the GORT-4; a few are discussed here. First, we added an easier story to both forms and thus the GORT-4 consists of 14, rather than 13, stories. Second, we used a linear equating procedure to adjust scores on the two test forms to allow the examiner to use scores on Forms A and B interchangeably. Third, we included bias studies that show the absence of bias based on gender and ethnicity. Finally, several new validity studies have been conducted, including an examination of the relationship of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) to the GORT-4.

You can use the GORT-4 in a variety of settings, such as elementary and secondary schools, clinics, and reading centers. The two forms of the test allow you to study an individual's oral reading progress over time.
