What NFHS Rules Mean for Parents
The NFHS rulebook is the national baseline for high school flag football. Here is what that means in practice:
- Use NFHS as the national high school baseline. The NFHS writes the official rules used as the starting point for high school flag football across states that have adopted the sport.
- Check your state association for adopted options. State associations adopt NFHS rules and may publish local modifications or adaptions. Look up your state’s athletic association for details.
- Check your school, league, or tournament packet for local modifications. Individual schools, districts, and events may apply approved variations. The event or league’s published rules control when there is a conflict.
- For CIF-SS or California events, use the CIF rules guide first. When an event says it uses CIF rules, start with the CIF Girls Flag Football Rules guide. CIF and NFHS are related but not identical.
- For non-CIF tournaments in California, confirm which rules apply. Events may use CIF, NFHS, NFL FLAG, or organizer-specific rules. Always confirm before game day.

NFHS vs CIF Girls Flag Football
California families often ask how NFHS rules relate to CIF. Here is a practical comparison:
| Question | NFHS source guide answer | CIF / California note |
|---|---|---|
| Which rules should California high school families start with? | Start with the rules published by the event or league. If the event says CIF rules, use the CIF guide first. If the event says NFHS rules, use the NFHS rulebook. | For most California high school girls flag football, start with the CIF Girls Rules guide |
| Is the NFHS book the same as CIF? | No. CIF-SS has published its own girls flag football rules document. NFHS writes the national baseline. CIF may adopt parts of NFHS or publish its own rulebook; confirm with your school or event. | CIF-SS currently links its own rules PDF from its girls flag football rules page |
| Can tournaments use CIF, NFHS, NFL FLAG, or custom rules? | Yes. Tournament organizers may choose any ruleset. Always confirm which rules apply to your specific event before game day. | See the Tournament Rules guide for what to confirm at events |
| What should a coach confirm before game day? | Which ruleset the event uses; whether state adoptions or local modifications apply; and the exact format, field, and timing rules in the event packet. | See the full checklist below |
What to Confirm Before Game Day
Regardless of whether your event uses NFHS, CIF, NFL FLAG, or custom rules, confirm these items from the event or league packet before game day:

- No-run zones: whether they apply and where they are located
- Rushing and blitzing rules: how many rushers are allowed and from where
- Kicking and punting rules: whether kickoffs or punts are used or replaced by possession-by-rule
- Overtime: format and tie-breaking procedure
