This Head Start evaluation system was developed at the request of the California Head Start Directors Association. There was a broad-based input in all phases of its development, from Head Start directors, Head Start staff from all components, and Head Start parents. It was extensively field tested in one of the major California Head Start programs. In all, more than 200 people were involved in formulating items, in the pilot study, and in post evaluation sessions. The system includes evaluation schedules for the following twelve components: Education (bilingual, bicultural, handicapped children, facilities), Health, Social Services, Mental Health, Parent Involvement, Training and Career Development, Nutrition, Volunteers (other than parents), and administration. The format is a 4-point rating scale on which the evaluator reacts to a performance standard indicating: performance exceeds the standard; performance meets the standard; performance is somewhat below the standard and needs improvement; and performance is substantially below the standard and needs immediate improvement. Space is provided for comments and recommendations. (Author/RC)
