USSF, CalSouth, Presidio, and SDDA Changes (based on USSF PDI dated February 2017)

The United States Soccer Federation (USSF) has recommended two initiatives designed to enhance the development of youth players.  These two initiatives were implemented by CalSouth, Presidio, and SDDA beginning with the 2016-2017 season for play that began on or after August 1, 2016.  The two initiatives are:
1) Player age divisions will be aligned to calendar birth year, rather than the prior system of fiscal year or school year; and 
2) Small Sided Games in 06U - 12U.

The following chart depicts the changes for the 2021 - 2022 season.  Team Roster Maximums were increased for age divisions 09U - 14U on 02-20-19 (All players present at each game must play at least 50% of the game).

Note:  USSF has implemented a Concussion Rule Change which requires youth soccer programs to implement restrictions in heading the ball during practices and games beginning with the 2017 season.

        09U thru 11U – deliberate or accidental heading is not permitted in practice or games; restart with IFK for the opposing team

        12U – heading in practice is limited to a maximum of 30 minutes per week with no more than 15-20 headers per player;
               no restriction on heading in matches, HOWEVER, Presidio has implemented a No Heading policy in 12U beginning with the 2020 season

        13U thru 19U - no restriction on heading in practices or matches
