Official Derby Resources

REMEMBER! THIS HERE WEBSITE IS NOT AFFILIATED WITH THE WFTDA! I am providing links to official WFTDA information here as a convenient reference, but I could screw up, make a link wrong, fail to update with a change, or be eaten by wildebeests. Always double check that when looking for official information, you are looking at the most recent version of the official documents on or

Rules Documents:

Where it all starts! Read these! Read them again! Learn them, love them, live them! Seriously - this is the most important thing to know backwards and forwards as an official. There's also a PDF version, suitable for printing or downloading for offline use.

Just because this has a separate bullet point, don't be fooled - the Casebook is part of the rules. You haven't finished reading the rules until you've read the Casebook. Read this several times too.

Sometimes the WFTDA Rules Committee will issue clarifications. There's now a public part of the mostly private WFTDA forums where these clarifications will be posted. Watch this space in case you have questions!

This is a prior version of the rules. It's formatted very differently, but it's a good place to get a sense of where WFTDA derby has come from in order to flesh out your understanding of where it is now.

Officiating Documents:

Officially official standard practices. The things you should be doing when you aren't filling out paperwork. (As opposed to the Statsbook Manual, which tells you what to do when you are.) If you have a question that isn't answered in this document, check the prior edition. Everything not superseded in the current edition is still valid.

Using incorrect colors when interacting with skaters of color is an ongoing and serious problem in WFTDA officiating. All officials should carefully read this policy. The most important thing is that if you should miscolor a skater in this way, you should immediately apologize and then stop talking. Do not justify your action, and do not demand the skater accept your apology.

These are critically important for officials. This document covers pretty much all of the standardized communication that goes on between officials and between officials and skaters during a game. Also now available in handy chart form!

This is the indispensable thing you need to record the statistics for your games. Required for sanctioned games, recommended for ALL games. Also available in A4 formatting for printing in exotic foreign lands. Like Norway.

This is the indispensable thing you need to effectively use the other indispensable thing. The first document you should read to answer the question, "How do I even NSO?"

WFTDA is developing online courses to help officials improve and qualify for certification. If you wish to be a certified official (and you may not, and that's OK too) this is where you take your classes and your tests.

What all the best dressed officials are wearing. Note that this is only mandatory for WFTDA postseason play, but you can expect that a large majority of head officials will require this for their games as well, so you may as well be prepared to follow it all the time.

Safety Related Documents

How to play safe. VERY IMPORTANT! Your WFTDA insurance will not apply if you don't follow these. EVERY official should be familiar with this document!

WFTDA has issued some excellent guidance on how to estimate when to remove skaters from play for concussions. Remember that there is no substitute for the judgement of a trained medical professional, but every official, skating and non-, should be familiar with what to look for. There is also a PDF version.

Detailed instructions for how to properly fit your equipment. Very important for skating officials! NSOs should be at least somewhat familiar with it as well, so they can potentially catch issues with skaters' and refs' gear.

This is a Q&A from WFTDA risk management. Reminder that WFTDI Risk Management Guidelines are REQUIRED for sanctioned and WFTDI insured play. For all other play, check with your insurer.

Official non-officiating documents of interest to officials:

Applies to all participants in WFTDA derby, including skaters, officials, coaches. This is not a joke, and should be taken extremely seriously.

How to handle especially naughty people. Note that the officiating guidelines now explain where fouled out and expelled skaters can sit, so this is primarily concerned with paperwork.

All the things that need to happen for a game to be officially sanctioned. HNSOs should be *very* familiar with this document. Update: as of the December 1st, 2017 rules update, officials CAN be expected to enforce this document!

Primarily of interest to officials only because this is where the 14-skater roster limit went. And that only applies to sanctioned games now. (Update: it's now 15. But still only applies to sanctioned games.)

Mostly concerned with what happens after a forfeit, HNSOs should still be familiar with this document, as it includes what should be marked on the IGRF in that event.

Detailed instructions for how to lay out a regulation WFTDA track.

Personal Documents:

Make a games history! Do it now! Seriously... do NOT wait until 100 games in, and then try to remember who was the HNSO for that time a year ago when you worked North Texas Derby Revolution Fightin' Unicorns vs. The San Fernando Valley Like OMGs. (Although if you worked that game at K-Town in 2016, it was me. You're welcome.)

Official Thing Un-Officially Reposted Here:

The WFTDA Rules committee issued a non-confidential FAQ on ceding cuts that has not been officially posted anywhere. It is reproduced here for convenience, but bear in mind that this site is NOT an official source for WFTDA information! Use these for guidance, but check with your reps to make sure they are still current!
