Colorado Homeschool Immunization Requirements: What You Must Keep on File

When you withdraw your child from a Colorado public or private school and begin a home-based educational program, the school no longer controls your child's immunization records. Those records belong to you — and the state's home education statute requires that you keep them. The ordinary rule is permanent retention of an immunization record or applicable legal exemption form, not routine submission to the state or district.

Here is the precise legal picture.

What the Law Actually Says

Under C.R.S. §22-33-104.5, parents operating a nonpublic home-based educational program must maintain immunization records on a permanent basis. The statute groups immunization records alongside two other required document categories: attendance records and assessment results (standardized test scores or portfolio evaluation letters from odd-year testing).

The requirement is to retain the records — not to submit them to the Colorado Department of Education, not to report them annually to your school district, and not to have your child's vaccination status reviewed by any district official unless specific legal circumstances arise.

Exemptions Are Available

Colorado recognizes legal exemptions from immunization requirements. If your child relies on an exemption rather than an immunization record, retain the applicable legal exemption form with your permanent homeschool records. The exact form and any required public-health steps depend on the exemption, so use current Colorado Department of Public Health and Environment (CDPHE) instructions when completing it.

Who Can Request Your Records and When

The same procedural protection that applies to your attendance logs applies to your immunization records. A district superintendent cannot demand to inspect your home-based program's records arbitrarily. The statute requires 14 days written notice and probable cause to believe the program is violating state guidelines before any demand for records can be made.

In practice, routine immunization record requests from school districts to homeschool families are uncommon. Immunization status can become relevant when a homeschooled child participates in a public school activity — joining a sports team under CHSAA eligibility, taking part-time classes through the district, or enrolling in a concurrent enrollment program at a local community college. Those programs may have their own documentation rules, so confirm the current requirements with the institution before participation.

Transferring Records When You Withdraw

When you formally withdraw your child from a public school, the school will typically offer to transfer academic records. Vaccination records maintained by the school nurse's office may or may not be automatically included in what the school sends you. Request them explicitly in your withdrawal communication if you want the school's copy.

Having the school's immunization records in hand before you withdraw simplifies your own record-keeping. You'll have a complete documented history in one place without needing to reconstruct it from pediatrician records later.

If your child is currently enrolled in a private school with its own immunization documentation practices, review the school's policy on records release when you provide notice of withdrawal. Private schools generally cooperate with records requests, but some have their own procedures for releasing health records that differ from the public school process.

Practical Record-Keeping Setup

For a homeschool program's permanent files, the immunization component is the simplest to organize. Retain one of the following, as applicable:

• A copy of your child's complete immunization record from the school or pediatrician
• An applicable legal exemption form

Store this document alongside your attendance logs and assessment records. These three categories together make up your complete compliance file under Colorado's home-based education statute. None of them are submitted anywhere on a regular schedule — they are retained at home and produced only if a district ever establishes the legal threshold for requesting records.

Keeping Records Current Over Multi-Year Homeschooling

One aspect that trips up families who homeschool for several years: immunization schedules continue. Booster shots, adolescent vaccines like Tdap and meningococcal, and any new recommendations that come into effect during your homeschool years need to be added to your records as they happen.

Your pediatrician maintains the authoritative immunization record and can print a copy at any appointment. Make it a habit to request an updated copy annually or after any vaccination appointment and file it in your homeschool records. This ensures that when you need current documentation — for a sports physical, concurrent enrollment, or re-enrollment — you're not scrambling to contact the pediatrician's office under time pressure.

For families using the CDPHE online immunization record system (CIIS — Colorado Immunization Information System), ask CDPHE or your pediatrician about the current options for viewing and printing your child's records through the state portal.

When Immunization Status Becomes Relevant to Re-Enrollment

If you ever re-enroll your child in a public or private school after homeschooling, the school will request current immunization records or a valid exemption at that time. A gap in school-administered immunization tracking during your homeschool years is normal and does not create problems during re-enrollment, as long as you can document current status through your own records or your child's pediatrician.
