In 1973, the Virginia State Board of Education and the school board, faculty, and students of Buena Vista (Virginia) approved a four-quarter voluntary extended school-year plan for the Parry McCluer High School. This paper describes the review and planning process, as well as some of the program's outcomes 20 years later. Some of its objectives included: to increase the utilization of school facilities; to provide an optional fourth quarter in which students may enroll on a voluntary basis promotion, remediation, enrichment, and acceleration; to provide a cooperative work experience for students below the legal working age; to increase students' achievement scores; and to decrease the dropout rate. In 1994, the school board evaluated the extended school-year plan. Outcomes included an increase in the utilization of rooms and facilities, an increase in pupil enrollment, an increase in achievement scores, a decline in the pupil dropout rate, and overwhelming faculty and student support for continuation. In the past school year, over 50 percent of the student population attended school year-round. (LMI)
