Except as detailed here, the Boys Lacrosse rules published by the National Federation of State High School Associations (NFHS) rules will be followed.  Rule changes are allowable as long as they are agreed upon by both coaches and communicated to the officials.

5^th/6^th Grade rule ammendments:

• No long sticks.
• Two hands on stick checks.  One-handed checks or poke checks that do not contact the stick or a gloved hand holding the stick will be considered a slash.
• No body checks.  This ban includes man-ball play.
• Gloves, helmets, arms pads and mouthpieces are required.  Rib pads are strongly recommended.  Goalies may play without arm pads, but a throat guard is required.
• Penalties result in the offending player being replaced by a substitute and the ball being awarded to the non-offending team at the point of the infraction.  No time is served in the penalty box, but the infraction must be explained to the player by the coach.
• If one team is ahead by 4 or more goals, the ball is awarded to the team that is down in lieu of a face off.
• No advancing the ball counts will be used.
• Derogatory language (starting with "damn") is not allowed.
• Keeping the ball in the box during the last two minutes is not enforced.
• No overtime play ^__ at tie at the end of regulation play is a tie.
• Older players may "play down" as goalies or as agreed upon by coaches.

7^th/8^th Grade rule ammendments:

• Two hands on stick checks.  One-handed checks or poke checks that do not contact the stick or a gloved hand holding the stick will be considered a slash.
• Body checks allowed, but two steps maximum going into the check, and the head and shoulder may not be lowered.  No take-out checks.
• Gloves, helmets, arms pads and mouthpieces are required. Rib pads are strongly recommended.  Goalies may play without arm pads, but a throat guard is required.
• If one team is ahead by 4 or more goals, the ball is awarded to the team that is down in lieu of a face off.
• No advancing the ball counts will be used.
• Derogatory language (starting with "damn") is not allowed.
• In case of a tie at the end of regulation play, 4-minute "sudden victory" periods will be played until a goal is scored.

The game is generally played with four 12 minute quarters using a running clock (i.e. the clock does not stop when the ball goes out of bounds, etc.)  During a running-time game, penalties are 1¼, for example a "1 minute" penalty will last for 1 minute, 15 seconds.  Five minutes is allowed between quarters, ten minutes between halves.  Two 2-minutes time-outs are allowed for each team per half.
