There is only one exception. If you are a brand new referee, who has never (in your LIFETIME) had a US Soccer Referee license AND your brand new license was effective on or after July 1 of the year you took your class, then your license is valid for that calendar year, and the next calendar year.
For latest information, look at the WA State Referee Web Site.
