Eight steps in a planning/program development model are explained: describing the present program, stating goals, listing present and needed human resources, listing present and needed physical resources, listing present and needed financial resources, identifying the relationships and processes for implementing the program, scheduling development activities, and evaluating the mainstreaming program. Forms and checklists corresponding to program development steps are appended. (SBH)
