Lifeguard screening questions: certification, scanning, rescue scenarios and rules for 15-year-old guards
On this page
Lifeguard screening questions should confirm three things fast: that the candidate holds a current lifeguard certification for the type of water they will guard, that their age and certification meet federal and state rules for that facility, and that they can describe what they actually do in the chair: scanning, enforcing rules and starting a rescue. The certification proves they passed a course. The screen shows whether they kept the habits and understand that the job is mostly preventing incidents, not reacting to them.
This page is for pools, waterparks, clubs, hotels, apartment communities, camps and municipal beaches. Many lifeguards are teenagers, so read hiring minors and work permits alongside it, and the interview guide for seasonal roles for summer hiring timelines.
Which lifeguard
| Facility | What changes | Ask the candidate |
|---|---|---|
| Community or club pool | Rotations, rule enforcement, swim lessons, sometimes chemical testing | "How many guards were on deck at your last pool, and how did rotations work?" |
| Waterpark | Wave pools, lazy rivers, slide landings, high bather loads | "Which attractions have you guarded?" |
| Waterfront (lake, beach, camp) | Open water, currents, rescue boards and boats, separate certification | "Does your certificate include waterfront skills?" |
| Hotel, apartment or fitness club | Often a single guard, guest service, fewer swimmers but less backup | "Have you guarded alone? What was your emergency plan?" |
| Head guard or aquatics supervisor | Scheduling, in-service training, incident reports, audits | "How did you run in-service training?" |
Certification and age rules
As of October 2026, not legal advice. Federal child labor rules, state pool codes and local health codes all apply, and they differ. We checked the examples below against the regulation or the certifying organization. Confirm the code for the facility's location.
Certifying organizations
The American Red Cross says students must be at least 15 by the last day of its lifeguarding course and pass swimming prerequisites, and that its Lifeguarding with CPR/AED for Professional Rescuers and First Aid certificate is valid for two years (Red Cross lifeguarding). Local YMCAs also train lifeguards, and depending on the branch the course may lead to a YMCA lifeguard certificate or to another organization's certificate, so ask which organization issued the card. Other certifying agencies exist; the question for the employer is whether the state or local code accepts the agency for that facility type.
State pool code example: New York
New York's State Sanitary Code sets lifeguard qualifications by "supervision level." For a pool-only lifeguard (Level IIa), 10 NYCRR § 6-1.31 requires a minimum age of 16, or 15 at a facility where a supervisory lifeguard is present; a current professional-rescuer CPR certification whose certification period does not exceed one year; the ability to swim 300 yards non-stop, surface dive to at least 9 feet and bring up a 10-pound object, and tread water for one minute; and a current certificate from a certifying agency acceptable to the State Health Commissioner (or qualifying training hours). Pool-and-beach lifeguards (Level IIb) have similar requirements with more training. Other states set their own rules, and some do not require lifeguards at every pool, so check the code where the facility operates.
Federal rules for 15-year-old lifeguards
The Fair Labor Standards Act child labor regulations allow 15-year-olds, but not 14-year-olds, to work as lifeguards at traditional swimming pools and water amusement parks when trained and certified by the American Red Cross or a similar certifying organization (29 CFR 570.34(l)). The same rule:
- Excludes natural environments such as rivers, lakes, ponds, quarries, reservoirs, piers and ocean beaches.
- Bars 15-year-olds from mechanical rooms and chemical storage areas and from operating power-driven equipment.
- Bars anyone under 16 from working as an attendant at the top of elevated water slides; certified 15-year-olds may guard the splashdown pools.
Hours limits for workers under 16 also apply, including during the school year. If you are screening a 15-year-old for a lake or beach, or for chemical testing duties, the answer is no under the federal rule.
Knockout questions
| Question | What a strong answer sounds like | Red flags |
|---|---|---|
| Which lifeguard certification do you hold, from which organization, and when does it expire? | Names the course and modules (pool, shallow water, waterfront, waterpark) and the expiry date; CPR and first aid current. | Expired, or "I think it's still good." |
| How old will you be on your first day? | Meets the facility's legal minimum. Ask only to confirm the legal age requirement. | Under 15, or 15 for a natural-water site. |
| The season runs [dates], including [weekends, holidays]. Can you work it through the end? | Yes, with school or sports conflicts named now. | Leaves in early August when the pool is open until Labor Day. |
| Can you attend the pre-season in-water skills check and in-service trainings? | Yes. | Reluctant to be tested in the water. |
Scanning and prevention questions
-
"Talk me through how you scan your zone."
- Strong answer: covers the whole zone, including the bottom and the area under the chair, at a regular pace; changes position to cut glare; watches for swimmers who are vertical in the water with little forward movement or head low; never turns their back on the water.
- Red flags: "I watch for people waving and shouting for help." Drowning is often quiet.
-
"How do you stay alert on a slow, hot afternoon?"
- Strong answer: rotations, posture, hydration, shade, changing scanning patterns, no phone in the chair.
- Red flags: describes chatting with friends from the stand.
-
"A group of teenagers keeps running and dunking each other. What do you do?"
- Strong answer: whistle and a short, clear instruction, explains the risk, escalates to a break from the water or a supervisor if it continues, without leaving the zone unwatched.
- Red flags: ignores it because "they're good swimmers."
-
"How do you deal with a weak swimmer drifting toward the deep end?"
- Strong answer: steps in early, speaks to them and the parent, suggests the shallow area or a swim test under the facility's policy.
- Red flags: waits to see if they get into trouble.
Rescue and emergency scenarios
Listen for the order of actions and for teamwork with the facility's emergency action plan.
- "You see a child slip under in the deep end. Walk me through the next minute." Strong: signals per the facility's plan so a backup guard covers the zone, enters with the rescue tube, reaches the victim, brings them to the edge, removes them with help, checks responsiveness and breathing, starts care and calls for EMS, uses the AED if needed.
- "Someone dives into the shallow end and floats face down." Strong: suspects a head, neck or spinal injury, uses an in-line stabilization technique from their training, gets backup and a backboard, and still prioritizes the airway.
- "Thunder is heard while the pool is full." Strong: clears the water under the facility's lightning policy and waits the required time before reopening.
- "After a rescue, what paperwork do you complete?" Strong: incident report the same day, facts only, witnesses, care given; notifies the supervisor.
Waterfront and waterpark specifics
- Waterfront: ask about currents, limited visibility, rescue boards, search patterns for a missing swimmer and buddy checks. Confirm the certificate includes waterfront skills and the guard is old enough for natural water.
- Waterpark: ask about dispatching riders at slides, wave pool zones and high bather counts. Confirm the age limit for the post (under-16 workers may not attend the top of elevated slides).
- Single-guard sites: ask how they would get help, call EMS and manage bystanders with no backup guard.
How lifeguard experience gets overstated
- A certification course described as a season of guarding. Ask where they guarded and how many hours a week.
- Swim team presented as rescue skill. Strong swimmers still need rescue training and judgment.
- Saves that were assists from the side. Ask what happened and what they did, then stop; do not press for drama.
- CPR from a community course rather than a professional-rescuer course. Check the card.
Scoring
Pass or fail
- Current certification for the facility type, from an organization the local code accepts.
- Meets federal and state age rules for the post.
- Season dates and in-service training accepted.
- Passes the in-water skills check before hire.
Scored 0 to 2 each (8 possible)
- Scanning technique and alertness.
- Rule enforcement and prevention.
- Rescue sequence and emergency action plan.
- Communication with patrons, parents and teammates.
In the submittal, record the certificate, issuing organization, modules and expiry; CPR and first aid expiry; facilities guarded; season availability; and a one-line summary of the candidate's rescue answer. Ask about the ability to perform the job's physical tasks, with or without accommodation, rather than about health conditions. Camps hiring guards who also act as counselors should also read camp counselor screening questions, and gyms with pools may combine this screen with fitness trainer screening questions.
Questions people ask
How old do you have to be to work as a lifeguard?
Under federal child labor rules (29 CFR 570.34(l)), 15-year-olds, but not 14-year-olds, may work as lifeguards at traditional swimming pools and water amusement parks if trained and certified by the American Red Cross or a similar certifying organization; they may not guard natural environments such as lakes, rivers or ocean beaches. State law can be stricter. New York's pool code, for example, sets 16 as the minimum for a pool lifeguard, or 15 where a supervisory lifeguard is present (as of October 2026).
How long is a Red Cross lifeguard certification valid?
As of October 2026, the American Red Cross says its Lifeguarding with CPR/AED for Professional Rescuers and First Aid certification is valid for two years, and candidates must be at least 15 by the last day of class. State codes can require shorter CPR currency; New York's pool code requires the CPR certification period not to exceed one year.
Is a pool lifeguard certification enough for a lake or beach?
Usually not. Pool and waterpark courses are different from waterfront courses, and federal rules bar 15-year-olds from guarding natural environments at all. Ask which modules the certificate covers and check the state or local code for the type of facility.
Should a lifeguard screen include a swim test?
The phone screen cannot test swimming, so use it to confirm certification, availability and judgment, then hold an in-water skills check before hire. Many operators repeat the certifying agency's prerequisite swim and a timed rescue.
