U10 Rules Package

The Board of Directors of the Indiana Youth Lacrosse Association – US Lacrosse Indiana Chapter has adopted the following rules package to promote an environment of play that will stress the importance of developing stick skills and maintaining correct body positioning.


The National Federation of State High School Associations (NFHS) authors rules for high school boys’ lacrosse. For 2017, US Lacrosse has produced a stand-alone youth rule book for ages 14U and below. The rule sets in this book align with the principles of the Lacrosse Athlete Development Model (LADM), helping to ensure age-appropriate rules that allow athletes to progress and reach their maximum potential. Youth 2017 Rules

Within the allowable flexibility of the U10 rules, the IYLA recommends the following default considerations:


  1. The size and dimensions for fields shall be reduced for appropriate play for this age.

  2. Play will be 8v8, with 3 middies, 2 attack, 2 defenders, and a goalie.

  3. Players will be allowed to use shortened sticks if appropriate for there size as long as it is within 37" to 42" in overall length.

  4. All time serving penalties will result in the offending player leaving the field for the assessed penalty time, however a substitute player will enter the field to avoid a man-down play.  The coaches should use this opportunity to instruct the player on the penalty and their play.  The resulting play shall be a "fast break" procedure.

Penalties are enforced with a “fast break” change of possession utilizing the following procedure:


  1. The ball will be awarded to the offended team at the restraining line of their goal area on the corner of the box.

  2. All Middies must remain behind the midfield line.

  3. The Attack and Defenders are situated in the offended team’s goal area.

  4. When the whistle blows, all players are released to play.
