There've been answers to this posted already, but since I noticed
that there were responses from various regions, I thought some
differences were worth noting:
 
NCAA:
        1. Goalie doesn't serve minors (penalty served by player on
                ice at the time the offence occured -- this is a royal
                pain if the penalty is on delay for a while, since
                there can be many changes by the time it's whistled!).
 
        2. Goalie serves majors (can replace by substitute goalie, but
                total on-ice strength reduced by one -- usually the
                team puts in their other goalie rather than play
                without one just to keep up the nos of `skaters'!!!).
                Another player from that team (not nec on the ice at
                the time) sits with the goalie in the penalty box, and
                enters the game at the end of the 5 minutes.  The
                goalie
                can't go out until the substitute goalie (assuming
                there
                was one!) has left the ice.
 
        3. Goalie serves misconducts (replace by sub goalie or player
        as
                in 2 above, no change in on-ice strength, goalie can't
                get back on ice until next stoppage of play after the
                10 minutes are over).
 
        4. Goalie `serves' DQs!!!!!!!!!
 
USA Hockey:
        1. As in NCAA 1.
 
        2. Goalie doesn't serve majors -- treated as in 1 above with
                only difference being exit from penalty box after
                5 minutes instead of 2 minutes (yes, player must still
                come from the ice -- have been there at time of
                offence).
                Note that goalie does still get a game misc if gets a
                second major in the game.
 
        3. Goalie doesn't serve misconducts -- treated as in 1 above
                with only difference being exit from penalty box after
                stoppage after 10 minutes (yes, player must still come
                from the ice).
 
        4. Goalie does serve game or gross misconducts, or ejections!
 
        5. Goalie does serve match penalties (any associated additional
                penalties served by player from the ice).
 
Canadian Hockey Assoc. (used to be CAHA):
        1. As in USA 1.
 
        2. As in USA 2.
 
        3. As in USA 3.
 
        4. As in USA 4.
 
        5. As in USA 5.  (This level of agreement is very rare!!!!)
