The effects of an Extended School Year Program on student achievement, attendance, and stakeholder satisfaction were examined at one middle school in the Henrico County Public School Division. Several populations were used for this study: participating students, teachers, and parents. Data on English-social studies, math, and science were collected using pretests and posttests. Attendance was taken daily and maintained for participating students. Student and parent satisfaction data were collected using satisfaction surveys. Focus group interviews were conducted to collect teacher satisfaction data. The difference between pretest and posttest scores was used to measure achievement in English-social studies, math, and science. The Average Daily Attendance (ADA) during the Extended School Year Program was compared to the ADA of the school and the division during the previous year. Each student and parent survey response was averaged and reported. Teacher focus group responses were assigned domains and placed into categories and themes. Findings Achievement gains were reported in all subject areas. Attendance results indicated that when compared to the school and the division during the previous year, the Average Daily Attendance (ADA) during the Extended School Year Program was lower. Students were most satisfied with their teachers. Parents were most satisfied with the program being offered at no charge, and the transportation provided. Teachers were most satisfied with the daily schedule. / Ed. D.
