Abstract
These two studies examined the stability reliability for the Woodcock-Johnson-Revised (WJ-R; Woodcock & Johnson, 1989) and the Kaufman Test of Educational Achievment (KTEA; Kaufman & Kaufman, 1985) with approximately a 2-week retest interval for elementary-age students. Results indicated that across grade levels, the Broad Reading Cluster for the WJ-R remained stable. Most correlations for the clusters for mathematics and written language as well as the subtests for reading, mathematics, and written language were less than .90. Correlations for all composites and subtests for the KTEA exceeded .90. These data illustrate the need for more specific information in test manuals on test-retest reliability in order to enable examiners to select the most reliable measures.
