This report consists primarily of an executive summary of the findings of a study undertaken from July 1974 to September 1975 by Kirschner Associates, Inc., for the Office of Child Development, Department of Health, Education and Welfare, in order to assess the overall effectiveness of the Project Head Start Training and Technical Assistance Program (T/TA). The study addresses itself to the following questions: Are the Head Start objectives formulations, policy and guidance development, need assessment processes, T/TA planning, provider selection process, quality controls and the evaluation system all appropriate and effective? How effective is the T/TA delivery system? What is the quality of T/TA and what are its effects? Also included: a brief explanation of the methodology of the study, a short discussion of the advantages and disadvantages of directly funding local programs so they can purchase their own T/TA, and recommendations for change or improvement in all the aforementioned areas.
