At some point ALL new referees, as well as re-registering referees, mentors, or assignors will have to go to the USSF Learning Center to complete at least 1 module every year at no cost to them. Please don't do anything on the USSF site that you have to pay for. Any fees you should pay will already be folded into your fees you pay to register through Missouri, so we repeat, please don't pay for anything on the us soccer site cause if you do you can't get it back.
By Federal Law If you're 18 or older you also have to do SafeSport. It must be updated every year. It is free and should not cost you anything. You can also take it on the same learning center location https://learning.ussoccer.com/safeguarding UNLESS your existing SafeSport expires more than 60 days from when you want to take it. Otherwise you can take it by going directly to safesporttrained.org Going there you will want to know which of the 4 USSF approved modules you need to take next. Once it's done from there, on their menu, right hand side, look for "TRANSCRIPTS" and get/download a pdf copy and email it to MissouriSDI@gmail.com so we can save a copy at the state level (a USSF requirement again) and we can upload it to your profile in the learning center.
The 4 approved USSF modules are, in order of sequence:
SafeSport Trained - U.S. Soccer Federation
Refresher 1: Recognizing and Reporting Misconduct = U.S. Soccer
Refresher 2: Preventing Misconduct - U.S. Soccer
Refresher 3: Creating A Positive Sport Environment - U.S. Soccer
A new one must be taken every year. After all 4 have been taken, the sequence of modules starts all over again.
Suggest for returning referees you start with https://learning.ussoccer.com/safeguarding and ensure your Intro to Safe and Healthy is up to date, and if you're 18 or older your SafeSport must also be current.
