Site Traffic Management Supervisor (STMS) Refresher Course

An STMS warrant is current for three years from the date of successful attendance at the course.

(Note – once expired the holder is deemed to be no longer qualified, and cannot fulfil a TTM role, until a refresher is successfully completed).


You must renew your warrant within one year of expiry to retain the qualification.  If your STMS has expired for more than 1 year then you must attend and pass the full two-day STMS course again.
