USA Swimming B Time Standards — 10 & Under Boys

2024–2028 USA Swimming Motivational Standards

What is a USA Swimming B time?

USA Swimming B times are the entry point into the motivational time standards system. They represent a solid foundation for new competitive swimmers and are achievable within the first year of competitive swimming for most athletes.

What's the next standard after B?

The next motivational standard above B is BB. USA Swimming BB times mark a meaningful step up from B level. Swimmers at this stage have developed consistent technique and race skills. Many local meets use BB times as qualifying cuts.
