This study demonstrated an application of Schmidt-Hunter meta-analysis procedures to cumulate validities from three studies with small samples of psychiatric aides obtained over time in a single organization. The mean correlation weighted for sample size between a verbal ability selection test and a job-relevant training criterion across samples (N = 320) was .62 (p < .01). The variance in the individual correlations was not significantly greater than that expected by chance, providing evidence that there was no true variation in obtained validities across samples.
