The university child care center offers three different programs for parents in Family Student Housing. In order to qualify for the programs, the following requirements need to be met: at least one of the parents must be a full-time student at the university, the family must reside in university housing, and eligible children must be between the ages of 2 and 6.
    The first program is the nursery for infants and toddlers. The nursery is open from 8 a. m. to 6 p. m., and parents must schedule in advance of the times at which they plan to drop off the children.[5]There is no cost for the nursery as long as the total hours for each child per week does not exceed 30 hours.
    The second program is the university kindergarten, which is available to parents with children between the ages of 5 and 6 years. This kindergarten is fully accredited by the public school system. Teachers are all state certified, and the curriculum either meets or surpasses the curriculum of public kindergartens. The kindergarten is open from 8 a. m. to 4 p. m.
    The third program is an after-school day care program, open until 6 p. m. at a cost of $ 100 per school term. The after-school day care program is also fully accredited by the public school system.
    In addition to the nursery, the kindergarten, and the after-school day care program, the university child care center provides a list of available babysitters from a qualified, experienced pool of college students. If you would like more information about our programs, please see the director of Family Student Housing or make an appointment with me at the school.
