Can a libero serve in volleyball?

Under FIVB and most USAV rules, the libero may not serve. However, NFHS (high school) rules allow the libero to serve in one rotational position per set.

Full Explanation

Per FIVB Rule 19.3.1.1, the libero is not allowed to serve. This same restriction applies under NCAA rules. Under USAV domestic competition rules, the libero is similarly prohibited from serving. The exception is NFHS (National Federation of State High School Associations) rules, which permit the libero to serve, but only in one specific rotational position per set. If your league or school competition uses NFHS rules, confirm with your official before the match.
