Abstract
910 subjects were followed from pre-kindergarten through the latter part of first grade. It was found that scores on the Metropolitan Readiness Tests (MRT) obtained prior to kindergarten entrance correlated .65 with MRT scores obtained one year later, at pre-first grade level. Pre-kindergarten MRT scores predicted late first grade achievement in reading, spelling, and arithmetic approximately as effectively as did MRT scores obtained at pre-first grade level. Pre-kindergarten MRT norms based on the study sample are presented.
