Montana school enrollment requires proof of immunization under Mont. Code Ann. §20-5-405 — and kindergarteners need a physical exam on top of that. Whether you're landing in Billings, Missoula, Great Falls, or Bozeman, here's how to transfer records, get into Montana's MTSIIS registry, and get the kids enrolled without losing a week to paperwork chasing.

Under HIPAA, you have the right to request a complete copy of your child's medical records from any provider. Do this before the move — it's much easier to follow up with a familiar office than to coordinate across state lines from a new area code.
Montana-specific heads-up: If your child is approaching kindergarten age and your current state does not require a physical exam for school entry, ask your current pediatrician to complete one before the move. Montana requires a physical exam for kindergarten entry — having one done before you go saves you from scrambling to get a new Montana provider appointment the week before school starts.

MTSIIS (Montana State Immunization Information System) is Montana's statewide immunization registry, managed by Montana DPHHS. Schools and providers across the state can access it. Out-of-state records are not automatically in MTSIIS — you need to bring them to a Montana provider or county health department to get them entered.

Billings School District 2 — Montana's largest school district. Enrollment requires an immunization certificate (MTSIIS printout or provider-signed record), physical exam for kindergarteners, proof of address, and birth certificate. The Billings SD 2 enrollment office can assist families navigating the record transfer process.
Missoula County Public Schools — Enrollment is managed through the district's student services office. Missoula follows state requirements exactly. Families in the University of Montana community often find providers through the UM Family Medicine clinic for pediatric care and record transfers.
Great Falls Public Schools — The district processes enrollment at the district office. Families in Great Falls can access Cascade County health department for MTSIIS lookups and catch-up vaccines if needed. Malmstrom Air Force Base families should confirm whether TRICARE-connected providers submit to MTSIIS.
Bozeman School District — Growing rapidly due to the area's population influx. Schedule enrollment appointments early — the Bozeman district has seen higher demand in recent years. Bring all records physically; don't assume they'll be transmitted from the prior state in time.
Montana's rural geography means provider availability varies significantly by location. In Billings, Missoula, Great Falls, and Bozeman there are multiple pediatric and family medicine practices. In smaller Montana communities, family medicine physicians handle pediatric care, often with telehealth support from larger regional centers.
When establishing care with a new Montana pediatrician, bring:
The new provider will review records, update MTSIIS with any out-of-state doses, and issue a Montana-compliant immunization certificate for school enrollment. Schedule this appointment in the first week — it's the step with the longest lead time in a new city.
