Understanding Time Standards
Time standards set varying marks for swimmers of every age group, ranging from B to AAAA based on relative speed within the age group. Each age group has B standards, BB standards, A standards, AA standards, AAA standards and AAAA standards to give swimmers benchmarks for goal-setting and to track improvement.
Some club meets also set qualifying standards based on the USA Swimming times, requiring swimmers to be faster than, or in some cases slower than, an A time or a BB time, for example, for entry.
Per USA Swimming’s website: “Here you will find age group time standards designed to encourage age group swimmers to step their swimming up to the next level. These time standards guide you from just starting out in your age group to reaching your highest potential. Start at Level B and work your way up to Level AAAA times.”
