The Castro Valley High Parent-Teacher-Student Association (PTSA) is an organization which exists to foster communication and interaction between parents, students, staff and the community of Castro Valley High. We seek in our activities to enrich and enhance the learning environment of our students, inform our parents, support our principal, teachers, staff and be a positive force in our Castro Valley High Community. Parents, students, teachers and staff work together to promote our sense of community spirit, identify funding needs and financial goals, respond to the needs of our school and coordinate activities that bring our school community closer together.
