Colorado requires proof of immunization for all K–12 students, licensed child care, and camp attendance. Here's every form, where to get it, and the deadlines — all cited to official Colorado sources.
Last verified: September 8, 2026
Colorado Board of Health rule 6 CCR 1009-2 requires every student attending K–12 school, licensed child care, or camp in Colorado to have documentation of required vaccinations. The school or child care facility keeps this documentation on file.
Required vaccines for K–12 school entry:
Note: Colorado follows the CDC-recommended schedule for the number and timing of doses. The 2026–2027 immunization tables are available from CDPHE.
Colorado does not mandate a physical examination for school entry at the state level. However, individual school districts — particularly Denver Public Schools, Jefferson County, and Boulder Valley — may require or request a health assessment form. Sports participation typically requires a separate sports physical signed by a physician.
Even though the state doesn't require it, scheduling a well-child visit before school starts is the easiest way to get any needed catch-up vaccines and have your child's health records updated in one appointment.

Colorado operates over 80 school-based health centers (SBHCs) across the state, providing immunizations, wellness exams, and oral health services directly at school. If your child's school has an SBHC, they can often complete missing vaccines and provide the documentation the school needs — all without a separate doctor visit.
Check the CDPHE school-based health centers page to see if your child's school participates.
Colorado law gives families 14 calendar days from the date of enrollment to submit immunization documentation or an exemption form. After 14 days, the school must notify parents that the child may be suspended from attendance until records are provided.
If your child has started the vaccine series but isn't fully up to date, they can attend on a conditional status — but the school must have a written catch-up plan with expected completion dates. If doses aren't received on schedule, conditional status can be revoked.
Colorado accepts immunization records from other states as long as the doses meet Colorado's requirements. Bring your child's records to a Colorado pediatrician who can verify them and enter them into CIIS. If records are missing, the previous state's immunization registry may have them.
Colorado recognizes medical exemptions (signed by a licensed health care provider) and non-medical exemptions (religious or personal belief). For non-medical exemptions, Colorado requires parents to submit a Certificate of Non-Medical Exemption that has been signed by a healthcare provider after a vaccine education session, or to complete an approved online immunization education module. The governing rule is 6 CCR 1009-2.
