This report presents summary analyses of descriptive and comparative data collected during the 1973 Home Start evaluation project. The data presented were collected at 6 of the 16 Home Start sites, from three experimental groups of families (those entering the Home Start and Head Start programs in fall 1973 and those identified to enter Home Start programs in fall 1974). The families were looked at in three ways: (1) descriptively, to identify characteristics that are important in relation to some standards or norms;(2) comparatively, to determine whether the Home Start and Head Start programs serve similar populations; and (3) comparatively, to judge the success of the randomization procedures used to assign families to Home Start or delayed-entry control groups. The overall results of these three analyses are summarized first, then the summaries of each instrument are presented. Ten measures were included in the battery: two children's tests, two child rating scales completed by adults, one mother rating scale completed by the community interviewer, three parent questionnaires, a parent-child interaction measure, and child height and weight. Data tables and appendixes (field procedures and coding manuals) comprise approximately one-half of the document. (ED)
