The Marshalltown project was created to facilitate individualized prescriptive teaching of preschool handicapped and educationally deprived children at home based upon results of the Marshalltown Behavioral Development Profile. This staff development manual aids in the identification of the skills and knowledge necessary for the home staff to function effectively with the training staff, parents, and children in the home setting. Three training stages, or sequences are emphasized. Stage I consists of familiarizing staff with program goals, philosophy, and techniques. Opportunity is provided for intensive practice in use of curriculum. Stage II consists of on job training. Stage III is an inservice stage concerning transition from a totally structured school experience to home visits accompanied by senior staff members. The manual contains a day by day training format procedure. (DEP)
