Table view — season totals
Before RY2025 the U.S. Soccer exports don't record which course a referee took, so a "new" referee in those years is someone appearing in Arizona's records for the first time since 2010. Anyone who held a license in an earlier season counts as a recertification, including referees returning after time away.
The retention gap — first-year referees vs veterans
This is the number worth watching. Veterans are sticking better each year; first-year referees are leaving faster.
