NSSA is permitting “self-administration” of the test to be a licensed referee this year, given the current restrictions that many states/locales have placed on group gatherings due to Covid-19. This process does not preclude a club official from conducting a referee clinic; it is meant to provide an additional avenue for certification when a clinic can’t be held or isn’t available for an individual to obtain certification.
If you are, or want to become, a licensed NSSA referee you can request a certification package from the MSA Chief Referee, Chris Baning, at email@example.com or firstname.lastname@example.org she will email one to you. Your certification is good for three years, so if you took the test in 2019 or 2020 you do not to take it this (2021) year. Here is a link to the on-line Rules Book, which you will need to complete the test — you can print it out or download it to your computer. NSSA Rules Book
