Missouri Youth Sports Concussion Law
What Missouri law requires when a young athlete takes a hit to the head — in plain English, with the statute underneath it.
Checked against the official Missouri statutory text on 2 August 2026. Re-verified every year.
What this actually means for your family
The statutory detail is further down, and it is all sourced. But if you are here because your child got hit this week, these are the six things you came to find out.
My child took a hit to the head. Does the coach have to take them out?
Yes. If your child shows signs of a concussion, or is suspected of having one, they have to come out of that practice or game right away. This is the part of the law that is nearly identical everywhere, and it does not require anyone to be certain — a suspicion is enough, and the coach is not supposed to wait for a diagnosis before acting.
Can they go back in the same day?
In practice, no. Missouri law does not use the words 'same day,' but it bars a return until a provider has examined your child and put a clearance in writing. That is not something that realistically happens between the third and fourth quarter, so the effect is the same.
Whose note does the school have to accept?
Missouri does not limit this to physicians. Any licensed health care provider who has been trained in evaluating and managing concussions, and who is working within their own scope of practice, can sign. That usually includes athletic trainers, nurse practitioners and physician assistants alongside physicians. Because the law describes the training rather than naming professions, the practical test is whether the provider can say they are trained in concussion management — so ask when you book.
Is there a minimum number of days out?
Not in the law. This surprises people, but the statute sets no minimum number of days — it just requires a provider to sign off. How long your child sits out is a clinical decision, not a legal one, and a provider who returns a child quickly is not breaking any law. This is the single biggest gap between what these statutes require and what current concussion medicine actually recommends.
Does the school have to help with schoolwork while they recover?
No. Missouri law is silent about school. It governs athletics only. That is a real gap, because recovering from a concussion is usually harder in a classroom than on a field — screens, noise, testing and concentration are exactly what an injured brain struggles with. Ask the school anyway, and if symptoms persist, ask about a 504 plan, which does carry legal weight.
What if the team is not run by their school?
No — and this is the gap most parents do not know about. Missouri's law stops at school sports. A club team, a travel team, a church league or a Saturday rec programme is outside it, so the coach who is legally required to bench your child at a school game has no such duty at a club game. Nothing stops a league from having a good policy of its own, and many do. But you have to ask for it rather than assume it, and the time to ask is at registration, not from the sideline.
Read the law itself, in full: Mo. Rev. Stat. § 167.765 (revisor.mo.gov). This is the text a school, a coach or an athletic director is bound by, so it is the page to print or forward if anyone tells you the rule is something other than what you have read here. Where a state's law runs across several sections, the rest of them are in the sources at the foot of this page.
If this happened in the last few days
Rule out the emergencies first.
A concussion is not usually a medical emergency, but a small number of head injuries are. Go to an emergency department now for a headache that keeps getting worse, repeated vomiting, seizures, slurred speech, weakness or numbness, one pupil larger than the other, or a child who cannot be woken or is unusually confused or drowsy. None of this is what the concussion statute is about, and none of it should wait for a clearance appointment.
Get the evaluation booked, and book the right kind.
The clearance your school needs has to come from a provider the law recognizes, and that list is different in every state — it is the third question above. Confirming that before the appointment saves families a wasted visit and a second co-pay more often than you would think.
Write down what happened while it is fresh.
The date and time, what the hit looked like, who saw it, what symptoms appeared and when, and who was told. This helps the clinician far more than a general 'he got hit at practice,' and if there is ever a dispute with the school about what was reported, it is the only contemporaneous record anyone will have.
Finding a provider who can sign it
Knowing what the law requires is one half of it; finding someone who can actually do the evaluation is the other. Our directory lists 62 verified concussion providers in Missouri across 23 cities, and you can filter by the kind of clinician the answer above calls for.
What makes Missouri's law different
Missouri's distinguishing feature is the hard 24-hour minimum sit-out — most model-law states only bar same-day return, while Missouri fixes a clock-based floor. Otherwise the statute is deliberately thin: it enumerates no specific provider professions (just 'licensed health care provider trained in the evaluation and management of concussions'), imposes no coach-training mandate, contains no immunity clause, no return-to-learn provision, and no coverage of non-school youth leagues, instead pushing operational detail into DHSS rules developed with the school boards association, MSHSAA, and a brain injury advocacy organization. It has not been amended since enactment in 2011.

The statute in detail
Everything above is the short version. This is what the law actually says, section by section, for anyone who needs the precise wording — a school administrator writing policy, a coach checking a duty, or a family that has hit a disagreement with a district.
Who the law covers
Youth athletes participating in the athletic programs of Missouri school districts (interscholastic sports). The Department of Health and Senior Services develops the guidelines, information, and forms in collaboration with a statewide association of school boards, a statewide activities association responsible for athletic eligibility (MSHSAA), and an organization specializing in brain injury support, education, and advocacy. Non-school club, municipal, and recreational youth leagues are not covered.
Education and acknowledgment
Each school district must distribute a concussion and brain injury information sheet to each youth athlete on a yearly basis. The form must be signed by the youth athlete's parent or guardian and submitted to the school district before the athlete may participate in any practice or competition.
Missouri Return-to-Play Law: Removal From Play
A youth athlete suspected of sustaining a concussion or brain injury in a practice or game must be removed from competition at that time and for no less than twenty-four hours. The statute does not identify who is authorized to make that determination or order the removal.
Missouri Return-to-Play Law: Getting Cleared to Return
The athlete must be evaluated by, and receive written clearance to return to competition from, a licensed health care provider trained in the evaluation and management of concussions.
Who the law lets sign the clearance

Return to learn
Not addressed in the statute.
What happens if the rules are not followed
This is the part families ask about most and the part these statutes handle least. Almost every one of these laws sets out duties without setting out a penalty for ignoring them, and most go further and grant the school and its staff protection from being sued over concussion decisions. What that protection covers, and where it stops, is a state-specific question:
Not addressed in the statute.
Two things are worth being clear about. Immunity clauses of this kind generally stop short of conduct that is willful or reckless, so they are not unconditional. And a school district's or athletic association's own rules sit on top of the statute and can be enforced through the school or the association even where the law provides no remedy — that route is often faster than any legal one. If you believe the rules were not followed and your child was harmed as a result, that is a question for an attorney licensed in your state. It is not something this page can answer, and it is not something a directory should pretend to.
Common questions
Whose note does a school have to accept to clear a concussion in Missouri?
Missouri does not limit this to physicians. Any licensed health care provider who has been trained in evaluating and managing concussions, and who is working within their own scope of practice, can sign. That usually includes athletic trainers, nurse practitioners and physician assistants alongside physicians. Because the law describes the training rather than naming professions, the practical test is whether the provider can say they are trained in concussion management — so ask when you book.
Can a student go back in the same day after a head injury in Missouri?
In practice, no. Missouri law does not use the words 'same day,' but it bars a return until a provider has examined your child and put a clearance in writing. That is not something that realistically happens between the third and fourth quarter, so the effect is the same.
How long does a student have to sit out after a concussion in Missouri?
Not in the law. This surprises people, but the statute sets no minimum number of days — it just requires a provider to sign off. How long your child sits out is a clinical decision, not a legal one, and a provider who returns a child quickly is not breaking any law. This is the single biggest gap between what these statutes require and what current concussion medicine actually recommends.
Does Missouri require schools to help with schoolwork after a concussion?
No. Missouri law is silent about school. It governs athletics only. That is a real gap, because recovering from a concussion is usually harder in a classroom than on a field — screens, noise, testing and concentration are exactly what an injured brain struggles with. Ask the school anyway, and if symptoms persist, ask about a 504 plan, which does carry legal weight.
Does Missouri's concussion law apply to club and rec league sports?
No — and this is the gap most parents do not know about. Missouri's law stops at school sports. A club team, a travel team, a church league or a Saturday rec programme is outside it, so the coach who is legally required to bench your child at a school game has no such duty at a club game. Nothing stops a league from having a good policy of its own, and many do. But you have to ask for it rather than assume it, and the time to ask is at registration, not from the sideline.
When did Missouri pass its youth concussion law?
2011. The statute is Mo. Rev. Stat. § 167.765.
How this summary was written
Each summary was built from the statutory text and, where the statute delegates, the state rule or athletic association policy it delegates to. Where a detail could not be traced to a primary source it was left out rather than guessed at, so a section reading “not addressed in the statute” means the law is silent — not that nothing applies.
Not legal advice. This is a plain-language summary of a statute, not legal advice, and it is not a substitute for reading the law or asking a lawyer about a specific situation. Statutes are amended; school district and athletic association rules sit on top of them and are often stricter. Every source used for this page is linked below so you can check it against the text.

What the law does not tell you
A statute sets the minimum a school has to do. It does not describe what recovery actually looks like, how long symptoms usually last, or which clinician treats which symptom — and on those questions the clinical consensus has moved a long way ahead of most of this legislation.
- The six-step return-to-play protocol — the graduated progression most of these laws point at without describing.
- Concussion symptoms and red flags — what warrants an emergency room rather than a sideline decision.
- The six stages of recovery — what the progression looks like in practice, and why the two-week figure misleads families.
