All new referees, as well as re-registering referees, should start the process at https://mrdp.omgtsys.com/MemberRegister.aspx
At some point ALL new referees, as well as re-registering referees, 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 will pay will already be folded into your fees to register through Missouri, so we repeat, please don't pay for anything on the us soccer site.
Suggest you start with https://learning.ussoccer.com/safeguarding and ensure your Intro to Safe is up to date, and if you're 18 or older your SafeSport must also be current.
For 2023 USSF has instituted a requirement that existing or new user (you) who wants to attend any entry course taught by a state, before you can now get your badge and be registered you must go to the learning.ussoccer.com/referee and create a profile to confirm your email address (if you're under 18 then your parents will have to add a 2nd address) once that's done, then you have to click on "Courses", the click on “Available Courses” and then look for "supplemental courses " on the left, then click on it and find the "Introduction to safe and healthy playing environments" and take that FREE module. This is now an annual requirement by USSF.
By Federal Law If you're 18 or older you also have to do SafeSport. It too must be updated every year. You can also take it on the same learning center location https://learning.ussoccer.com/safeguarding but not if your existing SafeSport expires more than 60 days from when you want to take it. Otherwise you can take it by going 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 [email protected] so we can save a copy at the state level (USSF requirement again) and upload it to your profile in the learning center.
Contact your DRA (front page along the bottom) if you have any other questions.
