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 …show more content…

Both tests were administered to 49 children with severe learning disabilities upon entering a regional center for learning disabled children. They were re-tested again two years later with the same tests for follow-up testing. The average age of the children was 11 years old and had a 2nd grade reading level. The results showed minor differences in mean test scores from the original testing of the WRAT and the PIAT. Follow-up test scores showed a change in test scores which were higher than the original testing scores. In follow-up reading scores were higher than spelling or math on the WRAT. On the PIAT reading and math were higher than spelling. When both tests were assessed there was no difference in the WRAT and PIAT reading or spelling scores but on the math subtest the PIAT had higher scores than the WRAT. Many have tried to come up with a reasonable explanation for the difference in math score of the WRAT and the PIAT. Scull and Brand propose that the math subtest of the PIAT may be measuring skills that students with disabilities are not limited in. The WRAT on the other hand tends to measure areas where students are weakest and may cause previous emotional and behavioral responses to having a learning disability. The author addresses the shift of spelling scores being lower than reading as a result of a student’s individual treatment program and has evidence to support the trend as common among learning disabled children. The PIAT is more consistent with grade placement and word recognition level. The WRAT is better at measuring skills with specific learning disabilities. Scull and Brand do not recommend either test for placement in teaching programs or detailed diagnostic work but say the
