CSF Membership is gained after qualifying grades are earned each semester. In order to become a member, the student must submit an application each semester. The application period takes place at the beginning of each semester (CHS students are informed of these dates through the daily bulletin and CHS website). A point system specified in the CSF State By-Laws establishes the membership requirements.

To secure eligibility for CSF membership, a student must earn sufficient points (10) from pre-approved course lists. The majority of the required membership points must come from University of California accepted course work (i.e. College Prep, Gate, Honors and AP classes).

Lifetime Membership (Seal bearer) is achieved by qualifying for four or more semesters between the 10th and 12th grade years, and one of those semesters must be from the 12th grade. Lifetime members earn the CSF Gold Seal on diplomas and transcripts and are recognized during Senior Awards and their graduation ceremony. In addition, these students are also eligible to be nominated by the chapter adviser for the Seymour Memorial Award.

* Membership counting towards life (seal bearer) membership begins with grades earned in the 10th grade year.

** Associate membership is for grades earned in 9th grade. Associate membership does not qualify for life (seal bearer) membership.
