This fourth volume of the Assessment, Evaluation, and Programming System (AEPS) Test presents a developmentally sequenced curriculum for young children (ages 3 through 6) who have disabilities or are at risk for developmental delays. It is designed to allow professionals to match a child's Individualized Family Service Plan goals and objectives with activity-based interventions. The volume is divided into two sections. The three chapters in section 1 provide an introductory overview of the AEPS. Chapter 1 describes activity-based intervention and the linked system approach to assessment, goal development, intervention, and evaluation using the AEPS system. Chapter 2 explains how to use the AEPS curriculum in conjunction with the AEPS Test. Chapter 2 also includes information about working with children with severe disabilities. Chapter 3 describes how to use child initiations, daily routines, environmental arrangements, and planned intervention activities to work on children's goals/objectives. Section 2 presents specific curricular content and strategies for goals and objectives in the six areas of the AEPS Test: (1) fine motor; (2) gross motor; (3) adaptive; (4) cognitive; (5) social-communication, and (6) social. Appendices contain a variety of sample intervention activities using different formats. (Contains 24 references.) (CR)
