The Site Case Study Report, Volume 6 of the seven volume National Day Care Home Study (NDCHS), describes the status of family day care in Los Angeles, San Antonio and Philadelphia. Open-ended interviews conducted with over 30 respondents ranging from state licensing staff to day care advocates provided the qualitative information needed to complement quantitative data collected through observations and structured interviews. This volume is intended to describe the context in which the study was conducted and thereby to provide the reader with a fuller understanding of the NDCHS findings. After an executive summary of and an introduction to the contents of the volume, case studies of family day care in the three cities are presented. Each case study has two parts: first, the setting for family day care is described and second, issues affecting family day care are discussed. In conclusion, the present status and regulatory future of family day care is explored. Recommendations of a policy seminar panel discussing the regulation of family day care are appended. (Author/RH)
