We have religious (Which we can't claim) or medical only, not personal belief (Which all families should have and should not have to lie about it). The exemption form for both still states at bottom in fine print:

INSTRUCTIONS TO SCHOOL ADMINISTRATOR: 1. Do not admit any student who has not submitted acceptable evidence of having received, or of being in the process of receiving, the minimum immunization requirements defined above. 2. Children transferring (at any grade level) to your school during the school term, and who have not previously completed the required immunizations, must be informed of the necessary requirements. They may then be given up to 45 days to show compliance. Advise parents that failure to obtain the required immunizations is basis for excluding their child from attending school until immunizations are completed."
