The Wide Range Achievement Test 4 (WRAT4) is an achievement test which measures an individual’s ability to read words, comprehend sentences, spell, and compute solutions to math problems.[1] The test currently is in its fourth revision.[1]
The test is appropriate for individuals ages 5-94 years. The WRAT4 provides two equivalent forms (Blue and Green), which enables retesting within short periods of time without potential practice effects that occur from repeating the same items. The alternate forms also may be administered together in a single examination.[1]
The Wide Range Achievement Test 4 (WRAT4) is the latest offering in a test series first published in 1946. The various editions of the Wide Range Achievement Test (WRAT) have enjoyed widespread use in a variety of settings as a measure of the basic academic skills necessary for effective learning, communication, and thinking: reading and spelling words and performing basic mathematical calculations.
The WRAT4 is published by and available from Psychological Assessment Resources, Inc.. A computerized scoring program and interpretive report are also available.
