The officiating officials in a volleyball game are called referees. The referees stay on the sidelines of the court.
for school project
It matters if it's professional. If not, there can be a few as 1. If professional, there are 2-3 referees.
he does the same as other referees in other sports
there are 2 refs and 2 line watchers
There are usually 2 referees in a volleyball game. One is on the stand and one is on the floor.
Usually the two people with whistles are the first and second referees.
The games stops for a short time and the referees go to talk about the call and agree on who's right and who's wrong.
that would not work because there are three timeouts to a team
Volleyball has two referees, one to handle ball calls, and one to handle substitutions and timeouts. Also the first ref watches the offensive side while the second ref watches the defensive side.
I have never seen a "refee" at a high school volleyball game. There are two referees, the R1 who works from the elevated stand and the R2 who is on the floor at the opposite end of the net, near the scoring table.
