Castle High School's Summer School Program is open to current and incoming Castle High School students. No students from other schools will be accepted. Priority will be given to seniors needing to take courses to meet graduation requirements. Summer school will be taught in person and online. Please see the following courses that will be offered in person and the courses that will be offered online. Students may take up to 2 credits in the summer (1 online course + 1 in person course). Senior students who have met with their academy counselor may register for more than 1 online course. Courses with the notation "Remediation" means that a student must have taken the course previously and failed. The only courses that can be taken for acceleration is PE Lifetime Fitness & Activities, Computer Art, Junior Jump Start, and Poly Music 1. Please be aware that if a course has low enrollment it is subject to be cancelled. If payment has been made to reserve your seat and a class is cancelled you will receive a refund.
