Temporal Stability of the Metropolitan Achievement Test When Used with Learning Disabled Children

Abstract

The temporal stability of three levels of the Metropolitan Achievement Test (Primary I, Primary II, and Elementary) when administered to children with learning disabilities was investigated. Participants in the study were children identified by their schools as having learning problems based on discrepancies between their chronological age, mental age, and level of academic performance. The MAT was administered twice with a one-month interval between administrations. Many coefficients of temporal stability obtained were above the pre-established .80 cutoff point. It was concluded that the MAT is reliable when used with learning disabled children.
