An evaluation of the Maryland Day Care Voucher Demonstration was conducted after approximately 6 months of voucher use in two counties, one a small rural setting and the other a much larger suburban area. Findings were derived primarily from a mail survey of the staff, provider, and client populations in the two counties. A total of 14 staff, 279 family providers, 31 center providers, and 204 clients responded. Additional information was obtained through participant observation and supplementary interviews with a small number of participants. It was found that, overall, the change from direct county/provider contracts to day care vouchers issued to clients appeared to be a less consequential event than had been anticipated by state and county day care staff. Introduction of vouchers was seen to be a positive development in both counties' day care programs. Evaluation questionnaires are appended to the document. A separate booklet provides the state regulations governing family day care registration (From Article 88A of the annotated code of Maryland). (RH)
