The changes were recommended by the Men's and Women's Ice Hockey Rules Committee in June.
The rules include expanded video replay to determine: if goals are scored before a penalty occurs, if offsides or too many players on the ice are missed on a goal-scoring play and use of video of any source available to officials (not just TV broadcasts).
Other changes include:
* Players taking a faceoff no longer can use their hand to play a puck. Violation will result in a minor penalty (similar to NHL rule).
* In end-zone faceoffs, the defending team's player is required to put his/her stick down first. Previously, the attacking team did that. Center-ice and neutral-zone faceoffs will continue to require the visiting team to put their sticks down first.
* If the puck goes out of play during on an offensive team's attempt to score, the faceoff will remain in the attacking zone.
* In the case of high sticks and hand passes, faceoffs will now move one zone closer to the offending team's goal.
* If the goal becomes dislodged by the goalkeeper during a penalty shot or shootout, a referee can award a goal (if intentional or if a goal is obvious or imminent) or allow the team to shoot again.
* If a player awarded a penalty shot is injured and unable to take the shot, another player who was on the ice at the time of the infraction can be chosen to shoot.
* 10-inch goal pegs must be in place at all NCAA levels by the 2016-17 season.
* A Look-Up Line, a warning-track style line intended to impact safety near the boards, as been approved but is not mandatory.
* Women's hockey will get an experimental rule in which the puck can be played legally with a high stick.
