A sizable representative subsample of the standardization group for the Metropolitan Achievement Tests participated in both the Fall and Spring standardization programs. Fall and Spring test records were matched for all such pupils and Fall-Spring "growth expectancies" were derived. Additionally, the sample was split into three subgroups based on pretest national stanine and "growth expectancies" developed separately for below-average, average, and above-average achievers. Comparison of the "growth rates" of these three groups and of the total Fall-Spring sample with the national norms were made. The resulting data seem most appropriate for test users assessing the short-term growth of non-average groups. (Author)
