Abstract

This study compared children's performance on two tests of articulation. Children ranging in age from five years, four months to eleven years, six months were administered the Deep Test of Articulation and the Arizona Articulation Proficiency Scale: Revised. Comparisons between the tests were made of performance on individual sounds, total test performance, and differences in children identified as potentially in need of remediation. Results revealed differences in performance across tests on 15 of 21 sounds tested. Performance of almost 83% of the subjects varied across tests on at least one sound. Although some individual sounds displayed considerable variation between tests, total test performance and conclusions were similar. The data indicated, however, that the AAPS may fail to identify some children with consistent errors on relatively few sounds. The results are related to previous research, and clinical implications are discussed.
