Performance changes on the K-TEA: Brief form for learning-disabled students

Abstract

The purpose of the present investigation was to measure performance changes on the K-TEA: Brief Form over a 3-year retest interval. Fifty-two learning-disabled students were retested with the K-TEA: Brief Form following 3 years of special education services. Results showed an average decrease of 3.33 points in Battery Composite over the 3-year retest interval. Nonsignificant mean retest differences for Battery Composite, Math, Reading, and Spelling were found. Retest trait stability coefficients ranged from .69 (Mathematics) to .88 (Spelling), suggesting that the K-TEA: Brief Form is a reliable instrument in screening for changes in special achievement over an extended period. An examination of individual difference scores revealed significant within variability for each achievement area. © 1996 John Wiley & Sons, Inc.
