Diagnoses reading disabilities, and identifies strengths and weaknesses.

  • Age Range: 6.0 through 23.11 years
  • Time: 20-30 minutes

The Gray Oral Reading Tests is one of the most widely-used measures of oral reading fluency and comprehension in the United States. In this fifth edition, comprehension questions have been completely revised, and items are passage-dependent. Basal and ceiling rules have been streamlined for easier, more efficient, administration.

The GORT-5 can be used to identify students who may need more intensive, or explicit, instruction in reading. It can also be used a part of a test battery to diagnose specific reading disabilities. Comparison of intra-individual reading skills (reading rate vs. comprehension), helps tailor interventions to specific needs.

Progress can also be evaluated, through use of the two equivalent forms, which enable pre- and post-testing.  GORT-5 is a standardized, norm-referenced test, making it suitable for use in reading research. 

Each of its two equivalent forms contains 16 developmentally-sequenced reading passages, with five comprehension questions each. An optional miscue analysis system allows reading specialists to analyze reading errors, and tailor interventions to specific student needs.

The GORT-5 provides the following scores:

  • Rate– the time taken (in seconds) to read a story aloud
  • Accuracy– the number of words pronounced correctly
  • Fluency– a combination of Rate and Accuracy scores
  • Comprehension– the number of questions answered correctly
  • Oral Reading Index– a composite of Fluency and Comprehension scores

Rate, Accuracy, Fluency and Comprehension are reported as raw scores, grade- and age-equivalents, percentile ranks, and scaled scores, having a mean of 10 and a standard deviation of 3. The Oral Reading Index is reported as a standard score, based on a distribution, having a mean of 100 and a standard deviation of 15. Percentile ranks are also provided.

Reliability and Validity
For both forms, average internal consistence (content sampling) reliability coefficients exceed .90. The alternate forms reliability coefficients for the Oral Reading Index exeed .90. The average test-retest (time sampling) coefficients for the ORI for the same for (e.g. Form A to A, Form B to B) exceed .85. The average test-retest (time sampling coefficient) for the ORI for different forms (e.g. Form A to B and Form B to A) is .85.

Correlations of the GORT-5 scores with those of other well-known reading measures are large, or very large, in magnitude. Binary classification studies indicate the GORT-5 is able to accurately identify students with reading difficulties (i.e. sensitivity=.82, specificity=.86, ROC/AUC=.92, cut score=90, low false positives).  Considerable other validity evidence is provided in the Manual.

The GORT-5 Kit includes the Student Book, 25 Examiner Record Booklets each for Forms A and B, and a Manual, in a sturdy storage box.
