Methodology

How this tracker counts girls' flag football sanctioning, and why our number may not match the one you saw somewhere else.

Why the numbers disagree

If you searched for how many states have sanctioned girls' flag football, you probably found several different answers. All of them were published in 2026. All of them were, in their own terms, correct.

Over one summer, published counts included nine, 17, 18, 21, 23, and 24. The NFHS, NFL Flag Football, and individual newsrooms each maintain their own tally, none of them updates on a fixed schedule, and none of them states its counting rules. So the same week can produce a story calling a state the 18th to sanction and another calling it the 21st.

Three things drive the spread:

Different counting units. Some tallies fold the District of Columbia in with the states. Some don't. That is a one-count difference on its own.

Different definitions of "sanctioned." A state association can approve a sport in principle, approve it with a future effective date, run a multi-year pilot that already crowns a champion, or fully sanction it with a state championship. Reasonable people count these differently.

Lag. Association votes happen year-round. A tally published in April is stale by June.

What we count

We record a state as sanctioned when its state athletic or activities association has formally adopted girls' flag football as an interscholastic sport — by vote, and normally reflected in its constitution, bylaws or handbook — whether or not the first season has been played.

We record the championship structure separately, because it does not follow from sanctioning. Most sanctioned states crown a state champion. California does not: CIF sanctioned the sport in 2023 and it sits in the CIF bylaws, but CIF states plainly that flag football has no CIF Regional or State Championship, and the sections run their own playoffs. An earlier version of this page defined sanctioning as requiring a state championship, which would have wrongly excluded California. We changed it.

We record it as pilot when there is organized, association-acknowledged play without that formal vote.

We record it as not sanctioned when the association's own materials show it has not adopted the sport — for example, the sport is absent from its list of sponsored sports, or its governing body has considered the sport and not approved it. This is a checked status, not a guess. It does not mean nobody plays: in several states, schools play in leagues run with NFL clubs that sit outside the association.

We record it as unconfirmed when we have not personally confirmed the status against a primary source. This is not a judgment that no program exists. It means we have not checked yet, and we would rather say so than guess.

We treat the District of Columbia as a separate entry and report it separately from the state count. When we say "23 states and the District of Columbia," that is why.

What counts as a primary source

In order of preference:

1. The state association's own rulebook, sport page, championship manual, or board minutes
2. A press release issued by the association
3. Contemporaneous reporting that quotes the association directly and names the vote

Reporting that cites another outlet, or that cites an organizational tally rather than the association, is a lead for us to follow, not a source. We do not count a state on the strength of a secondhand number.

Verification dates

Every state page carries a last-verified date. That date is when a person opened the association's own materials and confirmed the entry, not when the page was last edited.

An entry with no verification date has not been confirmed. Those pages say so plainly, and they are excluded from search indexing until they are.

Update cadence

Association votes cluster around board meetings, which run heaviest in spring and fall. We review the full table monthly and update individual states within a week of a vote we become aware of.

The count on the homepage carries an "as of" date. If that date is more than a month old, treat the number as provisional.

Corrections

We keep a public corrections log. When we get something wrong, the fix is logged with the date and what changed, rather than quietly edited.

If you work for a state association and we have your state wrong, we would rather hear it from you than from a reader. Email corrections@prepflagfootball.com and we will correct it and credit the source.

College data

The college pages use the same standard, with sources one level down.

Governing bodies (NAIA, NCAA, NJCAA, 3C2A) are sourced to the body's own announcements and rules. We record the body's status, when it took effect, when its first championship is or will be held, and what it requires before it will create one.

Programmes are sourced to a conference's or a school's own pages. A programme is listed only after a person has confirmed it against a page covering its most recent season played or announced — a conference release naming its teams, or the school's own schedule or announcement. Because most college flag football is played in spring, lists for a new season often appear only in winter; we recheck each programme once they do, and remove any that a school or conference says has ended. We do not list programmes from recruiting sites or aggregator lists; we use those only to know where to look.

For each programme we record the school, its state, its governing body and division, its conference, and the first spring season it played. The state links back to that state's high school entry. We leave athletic scholarship information blank unless the school or its governing body states it, because it is the detail families care about most and the one most often wrong elsewhere. We list varsity programmes only, not club teams.

Programmes we have on file but have not yet confirmed are not shown.

What we don't track

We do not maintain rosters, schedules, scores, rankings or recruiting information, for high schools or colleges. Other outlets do that well, and a reference that tries to be a scoreboard stops being a reliable reference.

Known limitations

• Our sanctioned entries were initially compiled from reporting and are being re-confirmed against primary sources state by state. Entries that have not yet cleared that step are labeled.
• No published source enumerates which states are running pilot programs. Counts of pilot states circulate, but the underlying list does not exist publicly. Building it is ongoing work, and it is the main reason this site exists.
• Some associations publish sanctioning decisions only in board minutes, which are sometimes posted weeks after the vote.
