Abstract

Stability of K-ABC performance over a 2-year in terval with 25 nonhandicapped preschool children was examined. Global scale stability coefficients (corrected for restriction in range) for Time 1 testing (age 4) and Time 3 testing (age 6) were: MPC = .77; SEQ = .73; SIM = .76; ACH = .80. Subtest stability coefficients ranged from .53 to .75 for the Time 1/Time 3 comparisons. Repeated measures analyses of variance revealed significant increases in mean SIM scores from age 4 and 5 to age 6, and a significant decrease in mean ACH score from age 4 to ages 5 and 6. Overall, results indicated a high level of stability for both global scale scores and subtest scores. Less stability was indicated for profile patterns (SIM > SEQ, SIM < SEQ SIM = SEQ) and subtest strengths and weaknesses with this sample of non handicapped preschool children tested at ages 4, 5, and 6.
