All linked time standard pages will download various time standard documents. Keep in mind the age of your swimmer on the date of the meet that they wish to qualify for.
SD State Qualifying Times
These are the times required for a swimmer to attend the state swim meet. LCM stands for long course meters and those times are used for summer state meet qualifying. SCY stands for short course yards and those are the times for winter state meet qualifying.
USA Swimming Motivational Times
These times are leveled starting with B, BB, A, AA, AAA, and AAAA. Their primary use is to give kids a time to strive for and continue to improve to move up the levels over time.
B time standards (from USA Swimming motivational times) are required for the Tri-State championship meet.
8 & Under Tri-State Times
Because motivational times start at 10 & under rather than 8 & under, Midwestern swimming developed separate times for those swimmers.
