Learning in Early Intervention Programs: The Generalization and Maintenance of IEP Objectives

This study investigates the maintenance and generalization of preacademic objectives in children with mental retardation from early intervention programs. All the subjects (25) had mastered, according to their Individual Education Programs (IEPs), at least one task in the areas of color, shape, number, or big/little . They, along with children in three comparison groups, were given a series of tasks that included the same previously achieved IEP objectives (maintenance) and closely related tasks within the same domain (generalization). The findings indicated variability in maintenance and generalization for the children in early intervention, better for color and shape than for number and big/little. Success on generalization was below the usual standard indicating mastery (85%-100%). On the generalization tasks, children in early intervention performed similarly to older children with retardation who had lower standard scores (Peabody Picture Vocabulary Test-Revised) but roughly equivalent language ages. They performed less well than older children with retardation who had similar standard scores but higher language ages. They also performed less well than children without disabilities in regular preschool programs who were close in chronological age, but had higher standard scores and higher language ages. We conclude that performance on these tasks is closely tied to developmental age regardless of chronological age and "IQ" status. Findings are discussed in relationship to preacademic curriculum in early intervention programs.
