This report presents findings based on data obtained during the prospective phase of the study of employee mobility in Head Start programs. Problems were encountered in the study, making the projection of conclusions regarding the extent of mobility in Head Start programs quite tenuous. The extent of mobility reported and the causes of mobility from the viewpoint of Head Start employees and of the organizations employing them are discussed, with supporting data from questionnaire responses. Recommendations for future data collection from Head Start organizations are made, based on the experience gained from this study. The questionnaires used are included. (Author/SA)
