On the assumption that there will be a national program of day care for preschool children, the author presents the major issues involved. An attempt is made to bring together some figures on current need and available facilities, to examine policy considerations in the implementation of programs, to present some difficulties in providing adequate caretakers, and to discuss preferred strategies in the mix of programs to meet the needs. Policy and program considerations include: (1) level (a custodial-to-developmental continuum), (2) eligibility, (3) types of services (part-time, full-time, day, night, drop-in, etc.), (4) control, (5) costs, and (6) personnel. The author concludes with recommendations based on three assumptions: (1) Most families can provide children with good care if there are programs, facilities and personnel to help them when needed; (2) It is desirable to strengthen rather than dilute family ties; and (3) Programs should be at the developmental level. The focus is on day care centers for preschool children over three years old. Other arrangements for those under three years are discussed. (TL)
