A lifeguard certification is valid for two years from the date it is issued. To keep working you renew before it expires through a recertification course, which is 10 hours of in-person training. Once a certification has lapsed, most employers require the full course again rather than the shorter renewal.
Lifeguard certification is valid for two years from the date of issue. Some providers allow a grace period of around 30 days, but it varies by provider, and working on a lapsed card exposes both the guard and the employer to liability.
Updated for 2026. This article was reviewed in 2026 and the guidance below reflects how the course is run now.
A candidate renewing sits the same instruction, passes the same written examination at 80 percent, and completes the same skills evaluation as someone certifying for the first time. There is no shortened refresher.
The certificate names the participant, the course, the issue date, the expiry date, the certifying instructor and the issuing organization.
How long lifeguard certification lasts is two years from the date you complete the course, not from the date you started it or the date the card was printed.
You cannot work as a lifeguard on an expired certification. Most employers will not schedule you at all past the expiry date, and insurers treat a lapsed guard as unguarded water.
Renew inside the final few months of your two year window. Renewing early does not shorten the new term, so there is no penalty for booking ahead of the expiry.
