IHSLA lacrosse play abides by the National Federation of High School Associations (NFHSA) rules and is sanctioned by US Lacrosse. The IHSLA will not be following the NCAA Men's Lacrosse Rules as in previous years. The following two documents demonstrate the differences between NCAA rules and NFHSA rules for those teams engaging in interstate play:

NCAA vs Federation Rules (short version)
NCAA vs Federation Rules (long version)

The IHSLA does have some rules that are specific to Illinois high school lacrosse.

  1. Football helmets and shoulder pads shall not be permitted - no penalty - remove from game.
  2. Face Off - Wing midfielders cannot make contact with faceoff player's sticks or bodies while they are in the faceoff position. Penalty will either be playon (technical foul) or personal foul depending on the severity of contact.
  3. Regardless of where the ball goes out of bounds following a face off, if the officials cannot determine who was responsible for the ball leaving the field of play, in all cases, the ball will be re-faced.
  4. Limit lines are not required.
  5. The gloves and helmets do not need to be consistent in color nor adhere to the NFHS color rule, but otherwise will comply with the NCAA rules. The shorts, shirts, and undergarments will adhere to NFHS rules.
  6. Goalie shall not serve penalty time unless on penalties for which 2 or more minutes is assessed. If less than 2 minutes, the In Home will serve the penalty time, but the goalie's number will be listed in the book.
  7. Coaches can have meetings on the field near their benches.
  8. If one team leads by 10 or more goals in the second half, the clock will only stop for team and offficial time outs. The clock will return to "stopped" time when the differential between the scores reaches 7 or less.
  9. The 4 x 4 square at the center of the field in contrasting color is not to be enforced. The official will place the ball down on ground with sticks being parallel with the midline with neither the stick nor gloves touching the midline. (All other rules regarding the face-off position will apply.)
  10. Discretion will be used by the official relative to the new face-off rule in which the ball is whistled into play. As a general rule, the rule will be strictly enforced in varsity and JV games, but may be more leniently enforced in freshman games.
  11. Clarification: Officials will be told to walk the field and note the markings. If the field is not lined properly eg no substitution box marked, no crease, etc. and this is not corrected by game time, the home team will be assessed a technical foul which means there would be no faceoff with the visiting team being awarded the ball
  12. Clarification: Official will be told to enforce the horn rule which states if there is no working air horn, home team will be assessed a technical foul which means there would be no faceoff with the visiting team be awarded the ball.
  13. Stick Checks - Officials will observe mechanic of two (2) stick checks per game (2 per team), which may occur at any time (not NCAA 6 pairs of stick checks). This does not limit discretion of officials to check sticks. Coaches will have elective stick check as before.
