Age Group Guide




Age group guide

Note: AYSO traditionally organized each age group by the player's age on August 1, which grouped kids together by school year.  US Soccer (the national governing body for all youth soccer in the country) has asked all leagues to start using a calendar year age grouping.  This means the player's division is determined based on their age on January 1.
