The school also provides full time physical education and art and music in alternating semesters. Approximately 493 students in pre-kindergarten through fifth grade attend Winston Elementary School. Family income places most students in the lower socioeconomic groups. The school has an active PTO which provides supplementary financial support as well as other services, such as operating the school clinic. A parent volunteer program provides assistance in classrooms, the office, and the media center.
Volunteers prepare materials for teachers and work directly with students.
Students in kindergarten through fifth grade participate in assessment measures to identify strengths and weaknesses in the instructional program. At the kindergarten level, student achievement is measured by a skills checklist, the GKAP, and Marie Clay's Observation Survey of Early Literacy. The Observation Survey also measures student achievement on the first grade level. The Iowa Test of Basic Skills is administered in second through fifth grades. Third and fifth grade students also participate in the state Writing Assessment.
