*While relay qualifying times are listed, q times do not need to be achieved to enter relays at the A and B championship meets. Relays are entered based on the number of eligible swimmers already entered in each championship based on individual qualifying times. Each team is entitled to "pull in" non-eligible swimmers to create an A relay at the A championships if they do not already have four individuals in the meet and if that is the only relay they will be entering for that age group and gender. Individual event qualifiers must have achieved their qualifying times during the current season and must have competed in at least two weekend invitational meets during the current season.
