Darrell Sabers and Amy Olson reviewed the Wide Rage Achievement Test 4th edition (WRAT-4) in the Mental Measurements Yearbook eighteen edition. In their review Sabers and Olson mentioned differences and similarities between the WRAT-4 and the previous three editions of the WRAT. The WRAT was created to assess “basic academic skills necessary for effective learning, communication and thinking” in addition it evaluates people age 5 to 94 years old that have learning, behavioral, and vocational struggles. The test is separated into four subtests which measure reading, spelling, math computation, and sentence computation. The sentence comprehension subtest is recently added to the WRAT-4 due to previous criticism about the reading subtest, which did not include any reading, but otherwise no extreme changes have been made to the other subtests. The WRAT-4 also offers the choice of combining the word reading and sentence comprehension standard scores to obtain a reading composite score. While the WRAT-4 itself is easy to understand and gives clear directions for administration, the reviewers advise against administering the test as a group, the exception being the second halves of the spelling and math computation subtests but only if it is given in groups smaller than five. The test manual is large and contains information on how to score conversion appendages. Sabers and Olson suggest creating a smaller manual with only the necessary information to administer the test to make it more convenient. Standard score come with confidence intervals and percentile ranks based on age and grade. The reviewers recommend adding confidence intervals around the percentile ranks since they are easily interpreted and widely used.

The results showed that the PPVT-R was positively and significantly related to the WRAT reading subtest. There was no correlation between the arithmetic or the spelling subtests scores of the WRAT to the PPVT-R. Vance, Kitson, and Singer believe both the WRAT and the PPVT-R will continue to be popular tests due to their easy and brief administration. The tests are also good screening devices. The WRAT does a brief assessment of achievement while the PPVT-R is a quick estimate of vocabulary. Because of the small sample size, restrictions in grade range, and geographical location it is recommended that further study of the concurrent validity of the PPVT-R be done. Vance, Kitson, and Singer advice against applying the result of the study to different populations than the one this study was intended for.
