9.7 Liability, Negligence, and Substance Abuse Effects on Performance
Key Takeaways
- Negligence requires all four elements -- duty, breach of duty, proximate cause, and actual damages; the absence of any one defeats the claim.
- The physical educator's duty of care comprises adequate supervision, proper instruction including a documented progression, safe equipment and facilities, appropriate activity selection and matching, and emergency response readiness.
- Supervision must be general or specific according to the risk of the activity: high-risk activities such as gymnastics, aquatics, weight training, and throwing events require specific, proximate supervision.
- Anabolic steroid use produces documented physical and psychological effects including premature growth plate closure in adolescents, and stimulant use masks fatigue while increasing cardiac and heat-illness risk.
- Behavior changes signaling possible student substance use include unexplained performance decline, mood swings, withdrawal from teammates, and changes in attendance -- observations a teacher documents and refers rather than diagnoses.
Negligence: The Four Elements
Physical education carries more liability exposure than any other academic subject because it involves movement, equipment, and physical contact. Nearly every claim is a negligence claim, and negligence has four elements that a plaintiff must establish. If any one fails, the claim fails.
| Element | Question | Example |
|---|---|---|
| Duty | Did the teacher owe this student a duty of care? | A teacher assigned to supervise a class owes that duty to every student in it |
| Breach of duty | Did the teacher fail to act as a reasonably prudent professional would have? | Leaving a gymnastics class unsupervised to take a phone call |
| Proximate cause | Did the breach actually cause the injury? | The injury occurred during the unsupervised period and would have been prevented by supervision |
| Damages | Was there actual harm? | Documented injury, medical costs, lost activity |
The standard is the reasonably prudent professional -- what a competent physical educator with similar training would have done in the same circumstances -- not perfection and not hindsight.
The Duties of Care
| Duty | What it requires | Typical failure |
|---|---|---|
| Supervision | Be present, positioned, and attentive; supervision matched to risk | Leaving the area; being present but not attentive; supervising a high-risk activity from across the gym |
| Instruction | Teach the skill properly, in a documented progression, with safety instruction given and understood before participation | Allowing an activity the class was never taught; skipping progressions; assuming students know a rule |
| Equipment and facilities | Inspect regularly, remove and tag defective equipment, ensure appropriate fit, maintain safe surfaces and adequate clearance | Cracked bats, worn mats, unpadded walls near a court boundary, wet floors, ill-fitting protective gear |
| Activity selection and matching | Choose developmentally appropriate activities; match participants by size, skill, and maturity; account for known medical conditions | Full-contact activity with mismatched sizes; ignoring a documented condition |
| Emergency response | Have and follow an emergency action plan; hold current first aid, CPR, and AED certification; know where the AED is; document | No plan; expired certification; delay in activating emergency services |
Supervision standards
| Type | Definition | When required |
|---|---|---|
| General supervision | Overseeing the whole area, moving and scanning, immediately available | Low-risk activity in which students are performing taught skills |
| Specific supervision | Direct, proximate attention to a particular student or group | High-risk activity, new or complex skills, gymnastics, aquatics, weight training, throwing events, or any student needing individual attention |
The pivotal rule: never leave a class unsupervised. If a teacher must leave, coverage must be arranged first. A teacher who leaves and an injury occurs during the absence has an extremely difficult breach question to answer.
Special rules apply to locker rooms -- supervision must be arranged consistent with district policy and privacy law -- and to aquatics, where a certified lifeguard whose only duty is surveillance is required in addition to the instructing teacher.
Defenses and Related Doctrines
| Doctrine | Meaning | Limits for minors |
|---|---|---|
| Assumption of risk | A participant who knowingly accepts the inherent risks of an activity cannot recover for injury from those inherent risks | Requires genuine knowledge and understanding of the risk; courts scrutinize whether a minor could appreciate it. Never covers negligent supervision, instruction, or equipment |
| Comparative or contributory negligence | The injured person's own carelessness reduces or bars recovery | Applied cautiously to minors, whose capacity is judged by age and maturity |
| Waivers and permission slips | Document informed consent and acknowledgment of risk | A parent generally cannot waive a minor's right to sue for the school's negligence. Waivers are evidence of notice, not immunity |
| Good Samaritan laws | Protect a volunteer rendering reasonable emergency aid in good faith | Generally do not protect a person acting within a paid duty to respond, and never protect gross negligence |
| Governmental or sovereign immunity | Limits suits against public entities in some states | Varies substantially by state; often has exceptions for gross negligence |
The practical implication is the one teachers most often get wrong: a signed permission slip does not insulate a teacher from a negligence claim. It shows the family was informed; it does not license inadequate supervision, instruction, or equipment.
Risk Management in Practice
- Written plans -- a unit safety plan, an emergency action plan posted and rehearsed, and a concussion protocol
- Documented instruction -- lesson plans showing that safety rules and progressions were taught, and dated records of the safety orientation
- Scheduled inspections -- equipment and facility checks with a log, with defective items removed and tagged
- Current certifications -- first aid, CPR, and AED for staff
- Health information -- awareness of documented conditions such as asthma, diabetes, seizure disorders, and cardiac conditions, and access to necessary medication per district protocol
- Incident documentation -- objective, prompt, factual reports of every injury
- Environmental monitoring -- heat and humidity policy with modification thresholds, air quality, lightning protocols, and surface conditions
- Appropriate class size and grouping for the activity
Effects of Substance Abuse on Student Performance
The blueprint pairs liability with "effects of substance abuse on student performance, health, and behavior."
| Substance | Physical and performance effects | Behavioral signs |
|---|---|---|
| Anabolic-androgenic steroids | Increased muscle mass and strength with training; acne, hair loss, gynecomastia in males, virilization in females; tendon injury risk from strength outpacing connective tissue adaptation; cardiovascular strain; premature closure of growth plates in adolescents, permanently reducing adult height | Aggression and irritability, mood swings, depression during withdrawal, rapid unexplained size change |
| Stimulants (amphetamines, cocaine, high-dose caffeine, some pre-workouts) | Masked fatigue leading to overexertion; elevated heart rate and blood pressure; arrhythmia risk; impaired thermoregulation and increased heat illness risk; appetite suppression | Restlessness, rapid speech, insomnia, irritability, weight loss |
| Alcohol | Impaired coordination, reaction time, and balance; dehydration; impaired recovery, protein synthesis, and sleep quality; reduced next-day performance | Declining performance and attendance, mood changes, risk-taking |
| Cannabis | Impaired reaction time, coordination, short-term memory, and motivation; increased heart rate; respiratory irritation when smoked | Reduced engagement, attendance problems, changed peer group |
| Nicotine and vaping | Vasoconstriction and elevated heart rate; reduced oxygen delivery from carbon monoxide in combusted products; reduced endurance; airway irritation | Frequent restroom breaks, possession of devices, irritability between uses |
| Opioids | Respiratory depression; sedation; impaired coordination; high overdose risk, especially with illicitly manufactured fentanyl | Drowsiness, withdrawal from activity, constricted pupils, absence |
| Dietary and performance supplements | Not approved for safety or effectiveness before marketing; contamination and undeclared ingredients documented; effects unpredictable | Reliance on products, rapid unexplained changes |
The teacher's role
A physical educator is often the first to notice, because performance decline, absence from practice, and changes in a student's relationship with teammates are visible in this class before they are elsewhere. The role is to observe, document objectively, and refer through school protocol -- never to diagnose, accuse, search, or attempt to counsel. Observations should record specific behavior with dates, not conclusions.
Professionally, prevention is more effective than detection: skills-based instruction, accurate normative feedback, and a connected team climate reduce use more reliably than surveillance.
Common Praxis Traps
- Trap 1: Believing a permission slip prevents a lawsuit. It documents notice, not immunity.
- Trap 2: Leaving a class to handle something briefly. Arrange coverage first.
- Trap 3: Using general supervision for a high-risk activity. Gymnastics, aquatics, weights, and throws need specific supervision.
- Trap 4: Assuming assumption of risk covers a teacher's negligence. It covers only inherent risks.
- Trap 5: Confronting or searching a student suspected of substance use. Observe, document, refer.
- Trap 6: Forgetting growth plate closure. It is the distinguishing adolescent consequence of anabolic steroid use.
