In order to create a base of information about early childhood and related services that would be useful to chief state school officers and other education policymakers, the Study Commission of the Council of Chief State School Officers developed and distributed a questionnaire to its members. The commission's aim was to collect information on the services in each state that were available to young children from birth through five years of age and their families. The questionnaire elicited descriptions of services available. Descriptions included eligibility criteria, number of eligible children served, and source and amount of state or federal appropriations. Inquiries about programs were sent to state departments of education and state departments of public health, welfare, and human services. The content of the state profiles is provided in both text and tables. The state profiles are followed by a separate policy section that includes answers to the second part of the questionnaire. This second part requested details of state policy regarding early childhood services, coordination of state agencies' efforts, obstacles encountered, evaluation data collected, and areas of unmet need. A chart of responses is provided for quick reference. Responses came from the 50 states, the District of Columbia, Guam, and Puerto Rico. (RH)
