The Educational Performance of Children in Head Start and Control Groups. Final Report.
Cain, Glen G.; Barnow, Burt S.
This report is a re-analysis of the data collected and analyzed by the Westinghouse Learning Corporation (WLC) and Ohio University concerning the average impact of Project Head Start on the cognitive development of a nationwide sample of children. The re-analysis was considered necessary because of unclear methodological issues in evaluation research and the existence of much data that was not used in the WLC analysis. A basic question raised is whether the WLC data can be used to produce unbiased estimates of the effects of Head Start. Several formal models of Head Start Evaluation are presented in order to determine the conditions that would lead to biased and unbiased estimates. The WLC report did not describe its procedures for selecting children for Head Start and control groups. For the re-analysis, the following modifications of the WLC study were made: (1) use of ungrouped instead of grouped data, (2) expanded list of socioeconomic and demographic indendent variables, and (3) inclusion of the Head Start variable in a manner to allow for different effects for children from various ethnic groups and family structures. Findings generally support the original study, but indicate that Head Start was more effective than the WLC report indicated. (DP/Author)
