Missouri has a dual requirement that surprises nearly every family arriving from out of state: a Certification of Immunization from the Missouri DHSS and a physical exam within the last 12 months are both required for any student new to Missouri schools — regardless of grade. Not just kindergartners. Not just new-to-the-district elementary students. Every child, every grade. Under RSMo §167.181, Missouri sets one of the more document-intensive enrollment processes in the region. Here's how to prepare so the paperwork doesn't delay your child's first day.

Missouri's school health requirements are established under RSMo §167.181, with the immunization schedule administered by the Missouri Department of Health and Senior Services (DHSS). Missouri requires two separate documents for enrollment:
This is Missouri's biggest enrollment surprise. Most states require a physical exam only at certain grade thresholds (kindergarten, 6th grade, etc.) or not at all for enrollment purposes. Missouri requires a physical exam — completed by a licensed physician, APRN, or PA — within the 12 months before enrollment for every student who is new to Missouri schools, regardless of whether they're entering kindergarten or 11th grade. A teenager who had their last physical two years ago in another state will need a new exam before Missouri enrollment is complete.
If your child had a well-child visit within the past 12 months in your prior state, that documentation may be accepted — but contact your new Missouri school before assuming. The school nurse will review the physical exam documentation and confirm what meets Missouri's requirement. If a new physical is needed, your new Missouri pediatrician will complete it — schedule that appointment as early as possible.

Missouri requires Haemophilus influenzae type b (Hib) and pneumococcal conjugate vaccine (PCV) for children through age 5 — requirements that phase out after age 5 for most children but are enforced at preschool and early elementary entry. If you're enrolling a child age 4 or 5, confirm these are documented in your immunization record before enrollment. Your new Missouri provider can confirm what's current on your child's record and advise on documentation.
Missouri's statewide immunization information system is ShowMeVax. Healthcare providers, schools, and local health departments use ShowMeVax to track vaccination history for Missouri children. If your family is new to Missouri, your child's record will not be in ShowMeVax — the system only contains doses administered or reported by Missouri providers. Your child's complete out-of-state immunization history must travel with you in paper form until a Missouri provider enters it.
The Certification of Immunization Missouri schools require can be generated by a local health department or a licensed Missouri provider based on your documented immunization history. Bring your paper immunization records to your first Missouri provider appointment — they will review the history, enter prior doses into ShowMeVax, confirm whether Missouri's schedule is met, and issue the Certification of Immunization for your school enrollment packet.

Missouri provides a 30-day grace period after enrollment during which students may attend school provisionally while immunization and physical exam documentation is being assembled. This is longer than Indiana's 20 days but shorter than it sounds — scheduling a new-patient pediatrician appointment and getting the Certification of Immunization issued often takes most of that window. Start the paperwork process before you move so you're not racing a deadline in week 3.
When you establish care with a new Missouri pediatrician, bring:
Because Missouri's physical exam requirement applies to every student new to a Missouri school regardless of grade, this section is relevant whether your child is 5 or 17. The physical must be performed within the 12 months prior to enrollment by a licensed physician, APRN, or PA. It must document growth measurements, vision and hearing screening, and general health status. The school nurse reviews this documentation as part of the enrollment packet.
If your child's most recent well-child exam was completed in another state within the past 12 months, contact your former pediatrician and ask two things: (1) whether they can provide a summary note on office letterhead that meets Missouri's physical exam documentation requirement, and (2) whether they are willing to complete any Missouri-specific forms based on the recent exam. Many out-of-state providers will do this for established patients, which saves you from scheduling an urgent new-patient exam before the 30-day grace period expires.

One of the most overlooked aspects of Missouri's physical requirement is that it applies to high school students new to Missouri schools — not just younger children. A 16-year-old transferring from Kansas or Illinois is just as subject to the physical exam requirement as a kindergartner. If you have a high schooler who hasn't had a well-child visit recently, plan for that appointment as part of your Missouri enrollment timeline. This is a records and scheduling issue — contact your new school for the specific documentation they need.
Missouri needs both an immunization certification and a physical exam — start gathering both before your move. Request a complete signed immunization history from your current pediatrician. If your child had a physical exam in the past 12 months, ask that provider for a physical exam summary on office letterhead and ask if they can complete any Missouri-specific forms based on their records. This preparation can save 2–3 weeks of scrambling after you arrive in Missouri.
Enroll your child and present whatever documentation you have. Ask the school nurse explicitly what's needed for full enrollment and what the 30-day grace period covers. Confirm whether your out-of-state physical exam documentation is likely to be accepted or whether a new Missouri exam will be required. Start the search for a new Missouri pediatrician immediately — don't wait until week two.
Your new Missouri provider will complete the physical exam, review your immunization records, enter doses into ShowMeVax, and issue the Missouri Certification of Immunization — all of which close the dual enrollment requirement. Book this appointment in your first week if possible. If the provider is fully booked, ask whether the local county health department can issue the Certification of Immunization based on your paper records while you wait for a pediatrician appointment.
Every person gets one health story, and one private Family Stork email address every clinic already knows how to use. Missouri's dual requirement — immunization certification plus physical exam — means you're coordinating with multiple providers in two states at once: getting the physical summary from your former pediatrician, getting the immunization history transferred, finding a new Missouri provider before the 30-day grace period ends. Family Stork makes that handoff manageable.
Your former pediatrician sends the physical summary and immunization history to your Family Stork address. Your former specialists send their records. Your new Missouri provider files from the first appointment onward. One organized timeline, accessible from anywhere, so when the school nurse asks whether your child's physical is within the 12-month window, you already know the answer — and you have the documentation to prove it.
Your Missouri move is the perfect moment to start a complete family health timeline. $99/year, or about $10/month.
