Test validity over a seventeen-year period

Abstract

Data are presented for 692 employees between scores on LOMA-1 (a 15-minute general mental ability test) on the one hand, and attained job class (7 to 17 years later) and current job performance on the other. LOMA test scores correlated .60 with attained job class, and .29-.48 with current performance in four departments as measured by a production criterion.
