This document is the second in a series of evaluative reports directed to evaluation needs of Home Start planners and administrators. It focuses on implementation data about programs gathered during local site visits conducted in the spring and fall of 1972. The two basic evaluative questions asked are: (1) What was Home Start intended by its planners to be? and (2) How closely have the plans been realized at the end of the first nine months? Part I of the report examines initial planning documents, including minutes from earlier planning meetings, the "Home Start Guidelines," the "Evaluation Work Statement," and the 16 project proposals, in order to identify basic features of the new program. Documents are compared for consistency; in some areas they were found to say conflicting things, but on the whole, a clear model of the program emerges. Part II examines three types of implementation data, including: (1) statistics about families, staff, project characteristics, and costs; (2) narrative descriptions of project organization and activities, using site visit teams; and (3) parent and child entering characteristics, based on standardized tests, questionnaires, and rating scales. Areas of stength and concern for the planning and implementation of Home Start are outlined. (DP)
