Rules comparison documents are developed annually by PAVO in conjunction with USA Volleyball and NFHS. Two documents are created - one compares NCAA, USAV and NFHS rules. The second document is a detailed comparison of NCAA and USA Volleyball rules and techniques. Both documents are available in PDF format (requires Adobe Acrobat Reader).
