USA Swimming releases motivational times to set varying marks for swimmers of every age group, ranging from B to AAAA based on relative speed within the age group. Each age group has B standards, BB standards, A standards, AA standards, AAA standards and AAAA standards to give swimmers benchmarks for goal-setting and to track improvement. Per the USA Swimming website, they are "...designed to encourage age group swimmers to step their swimming up to the next level. These time standards guide you from just starting out in your age group to reaching your highest potential."
