This fourth volume of the Assessment, Evaluation and Programming System (AEPS) is the curricular component for children at risk or with disabilities, from 3 to 6 years of age. Section 1 describes the linked systems approach to assessment, intervention, and evaluation using the AEPS materials. Section 2, the Curriculum Administration Guide, explains in detail how to use the AEPS curriculum in conjunction with the AEPS test. Section 3 describes how to plan and implement the curriculum using an activity-based approach to early intervention. This section includes information about classroom design and strategies for working with children of varying developmental levels. Section 4 presents specific intervention strategies for each goal in the fine motor, gross motor, adaptive, cognitive, social-communicative, and pure social domains of the AEPS test. Finally, section 5 introduces a variety of activities for embedding children's goals in intervention programming. An appendix discusses preschool curricula with similar goals. (PB)
