This study compared the reading subtests of the Wechsler Individual Achievement Test-Third Edition and the Peabody Individual Achievement Test-Revised/Normative Update. Scores were compared on these two tests in a group of 28 students ages 7 through 12 who were referred or reevaluated for suspected learning problems. The data were collected through a deidentified data set provided by a school building staff member or administrator and included such information as gender, age, and grade level as well as WIAT-III and PIAT-R/NU reading subtest scores. A t test of significance and the Pearson r Correlations were computed to see how the two scores covary. Implications of score variance are discussed.
