Luckily, it's much better in the USA, even though many regulations vary across state and county lines. Where I worked, we needed an in-pool refresher course and test every year, with a pool management course (chemicals, filter, etc) every 2 or 3 years. After getting you American Red Cross CPR certification, you needed to take a short refresher course every year for the next 2 years, after which you'd need to retake the course.
