Findings of a study that examined parental reactions to the implementation of Minnesota's statewide open-enrollment program are presented in this paper. Data were derived from telephone interviews conducted with 162 parents at the end of the 1989-90 school year. A three-way multivariate research design with eight dependent variables was used to estimate differences in enrollment decision-making behavior, home-school relations, and awareness/opinions about school choice among participating and nonparticipating parents, white and nonwhite parents, and parents with varying levels of education. Findings indicate that: (1) parents are aware that open enrollment exists but are unaware of other enrollment options available in the state; (2) parents are "active" enrollment decision makers, regardless of whether they choose resident or nonresident schools; (3) parents participating in open enrollment have a greater degree of influence in relations with administrators; (4) parents choose nonresident schools because of dissatisfaction with their resident school's educational services and/or administration; and (5) parents who keep their children in resident schools do so because of overall satisfaction with the school, community affiliation, social reasons, and/or school location. Other factors related to parental choice include race, parental level of education, and open-enrollment participatory status. Twelve tables are included. Appendices offer descriptions of Minnesota enrollment options and of unrestricted and restricted choice plans. (Contains 50 references.) (LMI)
