Concussion Laws by State

Every state and the District of Columbia has a youth sports concussion law, and they are far less alike than the phrase suggests. Who is allowed to sign an athlete back onto the field is the sharpest difference — in some states any trained licensed provider can do it, in others only a physician — and whether the law says anything at all about getting back into a classroom is the second.

The model these laws follow was written in Washington State in 2009, after Zackery Lystedt, a thirteen-year-old, returned to a football game after a head injury and collapsed with a brain hemorrhage. The law that followed has three parts, and almost every state copied them: an information sheet families have to sign, a rule that a young athlete suspected of a concussion comes out of play immediately, and a requirement that they not go back in without written clearance from a health care provider.

What states did with the fourth question — who counts as that provider — is where they diverge. Some name a long list of professions. Some name none at all and let any licensed provider trained in concussion management sign. A handful will accept nothing but a physician's signature. If you are trying to work out whose note your child's school will actually take, that is the line to look up first, and it is the first column in the table below.

The other real divide is return to learn. 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 — and yet most of these statutes are silent about school. A minority write an academic reentry protocol into law. The rest leave it to guidance documents a school is free to ignore.

These pages summarize statutes, not school district policy. Districts and state athletic associations routinely add requirements on top of the law — longer sit-out periods, specific clearance forms, mandatory baseline testing — and where the statute delegates the details to an athletic association, as several do, the association's handbook is the document that actually governs a Friday night game. Each state page says where that line falls.

They also describe the floor, not the standard of care. A statute permitting return after a single signature does not make that a good idea, and the clinical consensus has moved well ahead of most of this legislation. If you are managing an actual injury rather than a compliance question, the graduated protocol in our return-to-play guide is the more useful document.
