Birth Year Matrix
When determining the age group for a season, the year the season ends should be used for determining the birth year. Reference to a particular age group will now be the age plus a U (e.g. 8U or 12U). Age groups will be referred to as the age "and younger" (e.g. "8 and under" or "12 and under") For more age-group information please reference U.S. Soccer’s Player Development Initiatives.
