The Exercises to Encourage Development (EXTEND) Program for developmentally delayed students is described and evaluation results presented. Designed to provide attention to the child with developmental lags in the areas of motor skills, perceptual sensations, or expressive-receptive language, the program attempts to prevent potential academic problems. EXTEND provides materials and lesson plans for specific tasks to be completed by the child under the direction of the parent, and requires ongoing communication and evaluation between the parents and the coordinator. A 2 year study of the program, involving approximately 75 students each year, appeared to substantiate the program objective that specifically guided intervention would provide significant growth and help facilitate long range changes in the parent-child relationship.
