What is PTSA? Many families come from schools that have PTA's or PTC's. Here, at Castro Valley High, we have a PTSA which stands for Parent Teacher Student Association. We love Parent, Teacher, and Administrator members, we also value and encourage all students to participate and have a voice in their educational/social experience at Castro Valley High. Students can become Executive Board members of our PTSA! This is just one of the many opportunities that our high school students have to show that their voice counts, their opinion matters and that they can be responsible and have an impact in important matters. Seniors who join may apply for our CVH PTSA scholarship.
