The NFHS announced water polo rule changes for the next two school years on May 1, 2020. A (non-expert and likely incomplete) review of the changes can be found here, and a complete listing should be available at https://www.nfhs.org/activities-sports/water-polo/. The 2020-2022 NFHS Water Polo rule books are not yet available,.

The rule changes bring the NFHS rules more closely in alignment to the FINA/USAWP rules.

The most important changes are listed below. Please note that these are from the press release and so may not be exactly accurate. This post will be updated when the actual rule book is available.

There are also technical changes regarding leaving the field of play, entry after an exclusion, interval time, caps and other items.
