Overview

Effectively measure oral reading skills
The Gray Oral Reading Tests, Fourth Edition (GORT-4) provides an efficient and objective measure of growth in oral reading and an aid in the diagnosis of oral reading difficulties. Five scores give you information on a student’s oral reading skills in terms of:

Rate–the amount of time taken by a student to read a story
Accuracy–the student's ability to pronounce each word in the story correctly
Fluency–the student's Rate and Accuracy Scores combined
Comprehension–the appropriateness of the student's responses to questions about the content of each story read
Overall Reading Ability–a combination of a student's Fluency (i.e., Rate and Accuracy) and Comprehension Scores

The test consists of two parallel forms, each containing 14 developmentally sequenced reading passages with five comprehension questions following each passage. This widely used assessment helps you identify students who are below their peers in oral reading proficiency, diagnose specific reading strengths and weaknesses, and document student reading growth as a result of special intervention. GORT-4 can also serve as a measurement device for research into the reading abilities of school-aged young people.

 

GORT–4 norming sample

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 including race, gender, ethnicity, and geographic region.

 

Reliabilities and validity

The reliabilities of GORT-4 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 GORT-4 can be used with confidence to measure change in oral reading over time.
