This nutrition training guide is designed for use with classroom personnel in Head Start or day care training programs, including Child Development Associate programs. The guide identifies nutrition competencies needed by classroom staff, specifically the teacher; competencies required by food service personnel or professional nutritionists are not included. The identified competencies are related to the following areas: general knowledge of nutrient needs and functions; Head Start performance standards for nutrition; identifying needs and planning for them; meeting developmental and socialization needs through mealtime; sanitary practices; establishing sound food habits; and involving parents. Each competency specified is accompanied by lists of activities for trainees, criteria for assessing trainee competence, and resources for trainees or children. Appendices include the Head Start nutrition performance standards and guidelines for implementing them, a sanitation guide for Head Start centers, and a short essay on nutrition services for the handicapped.
