California’s concussion protocol for athletes works on a simple rule: any student-athlete suspected of a concussion must come out of play for the rest of that day and cannot return to practice or competition until a trained healthcare provider gives written clearance. From there, a staged return-to-play process, supervised by a physician, runs at least seven days before full contact resumes. The rules sit in Education Code § 49475 for schools and Health and Safety Code § 124235 for youth leagues, with the California Interscholastic Federation setting the return-to-play stages for high school sports.
Immediate Removal on Suspicion
The trigger is suspicion, not diagnosis. If a coach, trainer, or other staff member suspects a concussion or head injury during any athletic activity, the athlete has to be pulled for the rest of that day. There is no waiting period and no coming back later in the same practice or game, regardless of how the athlete says they feel.1California Legislative Information. California Assembly Bill 2127 Bill Analysis
A headache after a collision, confusion about a play, dizziness after a fall — anything that suggests something might be wrong is enough. Symptoms sometimes take hours to develop fully, and continuing to play during that window sharply raises the risk of a much more serious brain injury.
Who Can Clear an Athlete to Return
After removal, the athlete cannot return to any athletic activity until two things happen. A licensed healthcare provider trained in concussion management has to evaluate them, and that provider has to give written clearance. The provider must be acting within the scope of their professional practice, so a coach or school administrator cannot substitute their own judgment for a medical opinion.1California Legislative Information.

Written clearance is the paperwork the school will look for. A verbal go-ahead from a doctor’s office does not meet the statute.
The CIF Graduated Return-to-Play Stages
For high school athletes, the California Interscholastic Federation requires a staged return-to-play process on top of the doctor’s clearance. Under CIF rules, an athlete cannot return to competition sooner than seven days after a physician (MD or DO) diagnoses the concussion, and the athlete needs written physician clearance to begin and to advance through the stages.2California Interscholastic Federation. CIF Concussion Return to Play Protocol
- Stage I is rest: at least two full symptom-free days after seeing a physician, with no exertion at all, including weight lifting, jogging, or PE classes.
- Stage II is graduated aerobic activity, in four sub-steps from light aerobic exercise (10 to 15 minutes of walking or stationary biking at low heart rate) through moderate activity, strenuous exercise, and finally non-contact sport-specific drills. The athlete cannot advance more than one sub-step per day.
- Stage III is contact practice: controlled contact drills first, then full-contact practice. The athlete has to complete at least one full unrestricted practice before moving to competition.
- Stage IV is full return to competition without restrictions.
One condition catches families by surprise. The athlete has to be back to normal academic activities before Stage II begins. A student still struggling in class is not cleared to start physical progression, no matter how good they feel physically. If symptoms return at any stage, the athlete has to stop and consult the physician or the school’s athletic trainer before restarting.2California Interscholastic Federation.

Club Teams, Rec Leagues, and Travel Sports
The concussion rules are not limited to school athletics. Health and Safety Code § 124235 covers any organization, business, nonprofit, or local government agency that sponsors amateur sports for athletes 17 and under. That reaches club teams, recreational leagues, summer camps, and travel programs.3California Legislative Information. California Assembly Bill 2007
The youth sports law adds a requirement the school statute leaves to CIF and the physician. When a healthcare provider actually confirms a concussion (rather than just suspecting one), the athlete has to complete a graduated return-to-play protocol of at least seven days under the provider’s supervision. The organization also has to notify the parent or guardian of the date and time of the injury, the symptoms observed, and any treatment provided.3California Legislative Information. California Assembly Bill 2007
The Annual Information Sheet Families Have to Sign
Before an athlete can begin practice or competition each year, the school has to provide a concussion and head injury information sheet. The athlete and a parent or guardian both sign and return it. The requirement resets every year, not just when the student first joins a team.1California Legislative Information. California Assembly Bill 2127 Bill Analysis
Youth sports organizations have the same obligation. They must distribute an information sheet to every athlete annually, and athletes 17 and under need a parent or guardian signature.3California Legislative Information. California Assembly Bill 2007
The sheet typically covers common symptoms (headache, dizziness, confusion, memory problems, sensitivity to light), the dangers of returning to play too soon, and the legal requirements for removal and clearance. CIF publishes a standardized version many California schools use.
Full-Contact Football Practice Limits
California football programs face a separate set of restrictions aimed at reducing head-impact exposure before a concussion happens. These apply to high school and middle school football at any school district, charter school, or private school.4California Legislative Information. California Assembly Bill 2127 – Interscholastic Sports: Full-Contact Football Practices: Concussions and Head Injuries
- During preseason and regular season, no more than two full-contact practices per week.
- The full-contact portion of any single practice cannot exceed 90 minutes.
- During the off-season, full-contact practices are prohibited outright. The off-season runs from the end of the regular season until 30 days before the next season begins.
The statute defines full-contact practice as drills or live action involving collisions at game speed, where players execute tackles and other activity typical of an actual football game. Team camps count as practices under these rules.4California Legislative Information.

Academic Accommodations Are Not Automatic
California has no statute mandating a formal return-to-learn protocol for concussed students. The state’s concussion laws focus almost entirely on return to athletics. A student who is struggling with classwork, screens, or the noise of a full school day has no California law that automatically guarantees academic accommodations during recovery.
Accommodations are still available. A concussed student may qualify for a Section 504 plan if the concussion substantially limits a major life activity like concentrating or reading, and schools can offer informal accommodations (reduced homework, extended test time, screen breaks, permission to leave noisy environments) without a formal plan. None of that kicks in automatically the way removal from athletics does.
The CIF protocol addresses the classroom side only indirectly by requiring return to normal academic activities before an athlete advances to physical exertion stages. A student who cannot yet handle a full school day also cannot begin the athletic return process, but that is a gate on sports, not structured support in class.2California Interscholastic Federation.

What Happens if a School or League Ignores the Rules
California’s concussion statutes do not specify fines, criminal penalties, or automatic revocation of coaching credentials. Enforcement runs through two other channels.
The first is CIF itself. Schools that violate concussion protocols or the football practice contact limits risk sanctions from their CIF section, including probation, forfeiture of games, suspension from CIF-sanctioned events, or other discipline. For programs that depend on CIF membership, exclusion from postseason play is a real consequence.
The second, and larger, exposure is civil liability. If a student suffers lasting harm because a school ignored the removal requirement, allowed a return without proper medical clearance, or exceeded football contact limits, the school and its staff face potential negligence claims. California’s concussion laws effectively set the standard of care, so a school that departs from the statute gives a plaintiff’s attorney a clear benchmark for what reasonable conduct looks like.
Youth sports organizations face the same landscape. Because Health and Safety Code § 124235 requires them to build their own internal compliance procedures, an organization that lacks those procedures, or has them on paper but ignores them in practice, is particularly exposed when a young athlete is hurt.
