Few times a year, there will be swim meet that will have time standards in order for swimmers to participate.  

To find your swimmer's best official times (From a sanctioned swim meet):

• Team's website,  goto My Account>Members>your swimmer's name and navigate to Best Times tab.
• OnDeck App, Membership>Best Times

If you are registering for a swim meet that has time standards and your swimmer doesn't qualify, then it will show up in red.

Once you have your swimmer's best times, you can then check where they are currently at with the published time standards.

You can find the standards for our LSC (Local Swim Committee) and National Standards at https://www.socalswim.org/time-standards/.  Select from the drop down your swimmer's age group and sex.

LSC standards ( Spring A/G, JAG, Summer A/G, WAG...usually set every year, based on previous year's times)

Spring A/G   = Spring Age Group Championships (Formerly Spring JO's, March, SCY)

JAG             = June Age Group Championships (June, LCM)

Summer A/G = Summer Age Group Championships (Formerly Summer JO's, July, LCM)

WAG            = Winter Age Group Championsips (December, SCY)

An explanation on how time standards are set by USA Swimming (B,BB,A...set every 4 years) are below:  (Taken from: https://www.teamunify.com/akkkw/UserFiles/File/Time%20Standards%20creation.pdf)

USA Swimming Time Standards 

B, BB, A, AA, AAA, AAAA

USA Swimming publishes sets of time standards for various reasons. One of the reasons behind standards is their usefulness for setting goals. They are also used to control the size of swim meets, as each higher or faster level in the standards has fewer swimmers - as the standards get faster, a smaller number of swimmers achieve them. Almost every swimming federation in the world uses some form of stepped standards within their system.

Standards can also be used to offer swimmers a general idea how they match up with other swimmers in their age group and between age-groups, but raw times work better within age- groups. In a general sense they can be used to compare swimmers in different age-groups with each other, but just because a swimmer has "AAA" times as a 9-10 year old does not mean that same swimmer will get "AAA" times as a 13-14 year old. There are several reasons for this, including differing maturation rates, changing interests, and even injuries.

How are age group motivational standards determined? 

Time Standards by Percentile

This standard means your swimmer is ranked in the top 2% of swimmers their age-group, their same sex, in that stroke and distance.
This standard means your swimmer is ranked in the top 6% of swimmers their age-group, their same sex, in that stroke and distance.

This standard means your swimmer is ranked in the top 8% of swimmers their age-group, their same sex, in that stroke and distance.
This standard means your swimmer is ranked in the top 15% of swimmers their age-group, their same sex, in that stroke and distance.

This standard means your swimmer is ranked in the top 35% of swimmers their age-group, their same sex, in that stroke and distance.
This standard means your swimmer is ranked in the top 55% of swimmers their age-group, their same sex, in that stroke and distance.

This standard is for all swimmers with times below the "B" standard. Everything from 0.00 up to the "B" standard is a "C" time.
