How many challenges (video review requests) does a team get in volleyball?

Full Explanation

Under FIVB's Challenge System (introduced for top-level international competition), each team receives 2 challenge requests per set. A challenge is a request for video replay review of a referee decision (typically ball in/out calls or net touches). If the challenge is upheld (the original call is overturned), the team retains the challenge. If the challenge is denied, the team loses one challenge. NCAA Division I volleyball uses a video review system for line calls at selected venues. NFHS (high school) rules do not include a video challenge system. USAV domestic competition generally does not use video challenges. The availability of the challenge system depends on whether the venue has the necessary technology.
