US Youth soccer has mandated that the grouping of players according to their birthyear will change nationwide, with encouraged adoption of best practices in August of 2016. U.S. Soccer will go back to calendar birth years to align with international standards and Youth National Team programs.
US Youth Soccer will implement the best practice of calendar year age grouping for player registration beginning with the 2016-2017 soccer year. Using the school calendar for age groups is practiced only in the United States and Canada; as all other FIFA members go by the calendar year.
Previously, age groups were determined based on players born between Aug. 1 and July 31. The change to calendar year age groups will reflect the calendar year, or Jan. 1 to Dec. 31. Players are still allowed to “play up” or play in an older age group.
