The trustees and administrators of the Oxnard School District, which currently serves approximately 12,000 students, recognized as early as 1970 that additional school sites had to be acquired and new schools constructed to accommodate a very substantial increase in student enrollment. Oxnard is located in one of the nation's fastest growing areas: the city's current population is about 125,000; by the year 2000 it is projected to be 175,000. Since the 1976-77 school year, when student enrollment finally exceeded the available space as provided on a traditional September-June schedule, the Oxnard district has operated a four-track year-round education program. Oxnard's year-round plan, which was phased into every school in the district by 1986, provides for three tracks to remain in school while a fourth vacations; thus, the school operates at full capacity for 12 months a year. Some benefits the district has enjoyed because of its continuous education schedule include: (1) economy of scale for student enrollment in per-pupil expenditures; (2) more efficient use of instructional materials; (3) reduced student and teacher absenteeism; and (4) a reduction in vandalism, burglary, and graffiti. Numerous graphs, newspaper article reproductions, schedules, and forms regarding Oxnard's year-round education program are included. (4 references) (KM)
