Afterschool Programs Although the Mason Prep School day officially ends at 3:05 p.m., many options are available for students after school. Extended Day Offered on a flexible as-needed basis, the Extended Day program provides a supervised environment until 5:45 p.m., with time for homework as well as for recreation. Homework help is also available in Study Hall sessions conducted by staff members. Afterschool Programs Mason Prep welcomes the opportunity to coordinate various afterschool programs with outstanding organizations and professionals. Our programs provide our students in every grade with opportunities to expand their horizons through the arts, athletics, culture, math, science, strategy and engineering. The participants also continue to develop skills in the areas of communication, participation, fair play and persistence as the different activities broaden the world around them. Athletics The Mason Prep faculty, staff, and coaches strive to develop the whole child, and our athletic program plays a significant part in this effort. Our program is designed to teach basic fundamental skills and then build on those skills at appropriate age levels. Fundamental skills and strategies in several sports can be mastered in the eight years at Mason Prep, and athletes who continue through the middle school years can make an easy transition to high school sports. Mason Prep athletes also learn the meaning of hard work, integrity, responsibility, commitment, and sportsmanship - critically important traits for each athlete to take to the next level of sport and into adulthood. Mason Preps teams typically involve grades 4 - 8. We play area schools, giving our children an opportunity to make new friends through sport. Volleyball (girls) - Mason Prep fielded three volleyball teams for girls in Grades 5-8. The volleyball season runs from September to mid-October, with games played through the City of Charleston Recreational Volleyball League.Basketball (girls and boys) - The basketball program runs from mid-October through early February. Tennis (girls and boys, grades 4-8) - Tennis season takes place in the spring with competitions through the Charleston Tennis Center. Developmental Sports Before students enter a competitive arena, developmental teams are offered in basketball in grades K - 3. These teams participate in intramural sessions with volunteer parent coaches. Rather than a win/loss record, each individual's performing to the best of his or her ability and development of fundamental skills are the Mason Prep measures of success.Expenses $4,671,414 · grants $83,210 · revenue $6,117,363
