Picture of (WRAT4) Wide Range Achievement Test 4

BY GARY S. WILKINSON, PHD, IN COLLABORATION WITH GARY J. ROBERTSON, PHD

The fourth edition of this classic test measures the basic academic skills—reading, spelling, and mathematical computation—necessary for effective learning, communication, and thinking. This version features an entirely new subtest, Sentence Comprehension, to enhance the scope of the test and to meet the need for a measure of reading comprehension.

The WRAT4 includes four subtests:

  • Sentence Comprehension
  • Word Reading
  • Spelling
  • Math Computation

The Spelling and Math Computation subtests may be given to groups or individuals; Word Reading and Sentence Comprehension must be individually administered. The test’s two alternate forms (Blue and Green) can be used interchangeably as pre- and posttest measures or can be combined for a more comprehensive evaluation.

Because the WRAT4 offers both grade- and age-based norms, you can interpret test results according to the purpose of assessment. Grade-based norms increase the usefulness of the test in Grades K through 12. Age-based norms (up to 94 years) allow you to assess the basic literacy of older adults.

The WRAT4 is a quick, simple, and psychometrically sound measure of fundamental academic skills. It is helpful in diagnosing learning disabilities, assessing academic progress over time, evaluating achievement/ability discrepancies, checking progress in remedial programs, determining instructional needs, and assessing children whose performance is below that of their peers.
