Age Group Classification
There are seven different age group classifications recognized by United State Swimming (the governing body of the sport).
The Senior classification includes any age registered swimmer who has achieved the prescribed qualifying time for the event. Not all age group classifications are offered at every swim meet. The swimmers age on the first day of a meet will govern the swimmers age for the entire meet.
Levels of Achievement
Within each age-group there are seven nationally recognized levels of achievement based on times.
All swimmers begin as “C” swimmers. As they improve, they advance from “C”, to “BB”, “B”, “A”, “AA”, “AAA”, and ultimately “AAAA”. The times required for each ability level are published each year by United States Swimming. This permits fair, yet challenging, competition on all levels.
