This paper describes the development of a visual-motor evaluation instrument, reports an interrater reliability study, and illustrates the instrument's use in a preschool handicapped program. During Phase 1 an extensive literature search led to a compiled set of developmental norm data for reflexive and voluntary visual-motor development. Phase 2 included clinical use and revision of the resultant Erhardt Developmental Vision Assessment (EDVA). Phase 3 involved testing the EDVA for interrater reliability, which resulted in highly significant interrater agreement with the test author. A sample application is illustrated by segments of an EDVA used to integrate visual-motor components into an Individualized Program Plan (IPP).
