Described is the Marshalltown Behavioral Development Profile, developed for handicapped and culturally deprived children in the 0-6 year range, and designed to facilitate individualized prescriptive teaching of preschool children within the home setting. The profile check list is arranged under three categories of behavior: communication, motor, and social. Behavioral items are further grouped into age categories (1 month categories until 1 year, 3 month categories until 3 years, 6 month categories until 4 years, and 12 month categories until 6 years). The following are examples of profile communication items: watches speaker's eyes and mouth (2-3 months), combines words into simple sentences (21-24 months), and knows all basic colors (60-72 months). Motor skills are assessed by items such as grasps object placed in hand (3-4 months), walks alone (12-15 months), and alternates feet going upstairs (30-36 months). Social behaviors evaluated include waving bye-bye (7-8 months), indicating toilet needs (15-18 months), and answering phone (36-48 months). A score sheet is provided. The profile items are numerically matched to behavioral objectives and strategies found in behavioral prescription guides for the three areas. (See EC 052 348 through EC 052 350 for the guides). (DB)
