The Wake County Public School System (WCPSS) (North Carolina) first introduced year-round education in 1989. By 1994, the program had expanded to seven elementary and middle schools. Of the seven current year-round schools, six have solely voluntary magnet enrollment and operate on a multi-track system. The other is a single-track year-round school defined by an attendance area, although parents can request a transfer in or out of the school. Evaluation of the voluntary, multi-track schools reported here has been based on academic achievement, student attendance, and staff and parent attitudes. Findings from 3 years of evaluation indicate that the voluntary, multi-track schools are at least as effective as schools on a traditional calendar, and that they appear to produce more positive student, staff, and parent outcomes in some areas. Student achievement at a multi-track school is generally above the WCPSS average and is at expected levels relative to similar students in other schools. Attendance at the multi-track schools is higher than the system average, and staff and parent attitudes are positive and higher than system elementary school averages. The data available indicate that creating more voluntary year-round magnet schools is a cost-effective way to serve more students. Two attachments present some responses of staff and parents to the evaluation surveys. (Contains nine figures.) (SLD)
