Arizona A,B,C standards
These cuts are good for a minimum of 18 months and the cuts are good for all courses. So if you have a short course standard you can swim that event long course. The B standard is the JO standard while the A standard is the state qualifying time. once you achieve a state cut you are no longer able to swim that event at JO's.
These cuts are good for 18 months and each sectional meet has slightly different cuts, summer sectionals being the harder standard. Make sure you are looking at the right meet.
