A group of 38 preschool children, first evaluated when 2 to 4 years old, functioning within the borderline or mildly retarded ranges of intelligence, were reevaluated at the ages of 6 or 7 years. It was found that cognitive and linguistic limitations remained fairly stable over time. The most global of the early measures best predicted subsequent attainment, both for children with language skills significantly below performance and for those with more even function. Preschool language deficiencies reflected in a significant discrepancy between verbal and performance abilities in early intelligence testing were not subsequently associated with greater academic difficulties. At the time of reevaluation, receptive understanding of language exceeded expressive competence, and semantic skills were stronger than syntactic abilities.J Dev Behav Pediatr 8:12–17, 1987.Index terms:preschool follow-up, preschool language, mildly handicapped preschoolers, borderline intelligence, mild mental retardation.
