How do you determine a plus or minus rating in hockey?

If you are on the ice for a goal for it is rated as a +, and if you are on the ice for a goal against it is a -. Thus the higher the + the better. These stats are not kept for goalies and is very indicitive of a defenceman's performance.

A player receives a �plus� if he is on the ice when his team scores an even-strength or shorthanded goal. He receives a �minus� if he is on the ice for an even-strength or shorthanded goal scored by opposing team.

Generally, good defensive hockey players have good +/- ratings (not a lot of goals against are scored on their watch). It depends on what team you're on. On a bad defensive team, or one with a bad goalie, a low minus rating (like -4) might not be that bad. I.e. you're one of the better defensive players on that team. Plus/Minus Rating in HockeyRule 1: If you are playing even strength (5 on 5, 4 on 4, 3 on 3) and your team scores, you get a plus and the team scored upon gets a minus.

Rule 2: If you are playing on the powerplay (more men than the opposing team) and your team gets scored on, (the lesser team scores) your team gets the plus and the powerplay team gets a minus. But if the powerplay team scores, neither team gets a + or a -.

Rule 3: A penalty shot/shoot-out doesn't count for either team for a + or -
