Section 1: Introduction
NCAA Women's Volleyball is the collegiate variant of indoor volleyball played in the fall semester at NCAA Divisions I, II, and III. NCAA W's Volleyball uses the FIVB rule baseline with NCAA-specific modifications: best-of-5 set match format, NCAA libero rules, NCAA-specific video challenge framework, NCAA-specific challenge form for lineup, and the NCAA Volleyball Championship. The current edition is the 2025-26 NCAA Women's Volleyball Rules Book.
For the underlying FIVB rules see the sibling FIVB Official Rulebook. For the men's collegiate variant (spring sport, USA Volleyball-base) see NCAA Men's Volleyball. For NCAA Beach Volleyball see NCAA Beach Volleyball.
Section 2: Equipment
- Ball: spherical, leather/synthetic, 65-67 cm circumference, 260-280 g, FIVB/Molten approved
- Net: 2.24 m height (women's), 1 m wide × 9.5-10 m long
- Antennas on each side of the net marking the legal crossing zone
- Posts 0.5-1.0 m outside the sidelines, padded to a safe height
- Player apparel: team uniform with jersey numbers; libero must wear a contrasting jersey
- Knee pads recommended; ankle braces permitted
Section 3: Playing Area
- Court: 18 m × 9 m rectangular, divided by a center line into two 9 m × 9 m halves
- Attack line: 3 m from the center line on each side, defining the front zone vs back zone
- Service zone: behind the end line, full court width
- Free zone: minimum 3 m around the court perimeter (5 m at championship venues)
- Substitution zone between the attack line and the centerline on each side
- Coaching restraining line on each side
Section 4: Players & Officials
Team Composition
- 6 players on court per team
- Roster: typically 12-18 players for NCAA D1; one or two designated liberos
- Libero: defensive specialist who wears a contrasting jersey, plays only in the back row, and may replace any back-row player without counting against the substitution limit
Substitutions
- Up to 15 substitutions per set (NCAA framework — broader than FIVB's 6); substituted players may re-enter
- Libero replacements (libero in for back-row player) do not count against the 15 substitutions
Officials
- First referee (R1, on the elevated stand)
- Second referee (R2, opposite the R1)
- Two or four line judges
- Scorer + assistant scorer at the score table
Video Challenge Framework
NCAA Women's Volleyball uses a coaches' challenge / video review framework allowing review of: ball in/out (touch), antenna contact, foot fault on serve, net touch, ball-handling judgments at the 1st referee's discretion. Each team is allowed a defined number of challenges per match per the published Rules Book and conference adoption.
Section 5: Rules of Play
Match Format
- Best of 5 sets
- Sets 1-4: rally scoring to 25 points, must win by 2
- Set 5 (decider, only if needed): rally scoring to 15 points, must win by 2
- No upper cap; deuce continues until a 2-point margin is achieved
Service and Rally
- Service rotation: clockwise position rotation each side-out
- Serve must clear the net within the antennas; serve may contact the net (let serve permitted)
- Each team may contact the ball up to 3 times before returning over the net (block contact does not count as one of the 3 in indoor volleyball)
- Switching sides between sets; teams switch in set 5 at 8 points
Timeouts
- Two team timeouts per set (60 seconds each in NCAA)
- Technical timeouts at 8 and 16 points in sets 1-4 (per NCAA framework / conference adoption)
Section 6: Scoring
- Rally scoring: a point is awarded on every rally regardless of which team served
- Set 1-4: first to 25 points (must win by 2); set 5: first to 15 (must win by 2)
- Match won by first team to 3 sets
Section 7: Violations & Penalties
- Faults causing loss of rally: ball lands out, four contacts, double contact (controlled), catch or throw, net touch by player, antenna contact, crossing the centerline interfering with opponent, foot fault on serve, illegal server (out of rotation)
- Hand-setting standard: must be clean (no extended contact); the indoor standard is more lenient than the beach standard (which is in the Beach Volleyball entry)
- Misconduct sanctions: warning (verbal), penalty (yellow card), expulsion (red card — player out for the set), disqualification (yellow + red — player out for the match)
Section 8: Safety Considerations
NCAA concussion protocol: removal for actual or suspected concussion + graduated return-to-play assessment. Court surface and post padding inspected pre-match. Required: certified athletic trainer at every match; team physician + EMT at championship-level competition. Emergency action plan with AED access at every venue. WBGT not typically a factor (indoor sport) but ventilation/temperature managed for player welfare.
