Colorado Board of Health Rules 6 CCR 1009-2 require documented proof of immunization for school entry. Colorado is generous with timing: you have a 14-calendar-day grace period after enrollment to provide immunization documentation. If records aren't complete after 14 days, the student must have a documented plan to complete immunizations or an exemption on file.
Colorado Revised Statutes C.R.S. §22-1-123 governs student records. When you enroll at a new Colorado school, they'll request records from your former district. Keep your own copies of everything — out-of-state transfers can take time, and having copies avoids enrollment delays. Colorado schools are accustomed to receiving out-of-state transfers and typically accept provisional enrollment while records arrive.

CIIS (Colorado Immunization Information System) is Colorado's statewide immunization registry. If your child received any vaccines in Colorado previously, those doses are in CIIS. Your new Colorado pediatrician can access CIIS directly and print your child's complete immunization record. You can also contact your local public health agency for a printout.
For doses given in your previous state, bring a signed immunization record from your former pediatrician. Colorado schools accept a physician's signed record or a printout from another state's registry. Your new Colorado provider will enter out-of-state doses into CIIS.
Colorado's SBHC network: Colorado has an extensive network of School-Based Health Centers (SBHCs) that can help with immunizations, well-child exams, and record-keeping. If you're settling in and need quick access to healthcare, check CDPHE's SBHC directory for a center near your child's school.

When you establish care with a new Colorado pediatrician, bring:
Your new Colorado provider will enter out-of-state vaccine doses into CIIS, issue the immunization certificate for school, and handle any catch-up doses. Remember: you have 14 days from enrollment, so schedule this appointment during week one.
Colorado does not require a state-mandated physical exam for school entry. Individual school districts may have their own requirements — check with your specific district. However, if your child participates in interscholastic sports, CHSAA (Colorado High School Activities Association) requires a pre-participation physical.
Even without a state requirement, scheduling a well-child visit when you arrive is the most practical move — your new provider can complete the immunization certificate, enter records into CIIS, and establish your child's care in one appointment. Colorado's SBHCs (School-Based Health Centers) can also handle these visits if you haven't yet found a pediatrician.
