  • Category C (CAT C): High Speed (70km/h or greater) multi-lane roads (i.e. Motorways & Expressways)

About our STMS Practising Assessments

This assessment is for anyone who wishes to work on the roads as an onsite STMS. We offer STMS Practising Assessments for CAT A & CAT B roads.

The following practical tasks are completed for each closure type (i.e. Closures 1, 2, & 3):
  • Task 1: TMP Review
  • Task 2: Carry out pre-departure checks
  • Task 3: Check TMP to site conditions
  • Task 4: Carry out TTM crew briefing
  • Task 5: Installation of TTM
  • Task 6: Monitoring
  • Task 7: Removal of TTM
  • Task 8: Make provisions for unattended worksites

The duration of these assessments depends on the trainee's existing STMS qualifications & experience:

For new STMS (or STMS with a practising warrant >12 months expired)
The Verified Tasks (Closures 1 & 2) need to be completed as well as the Assessment Tasks (Closure 3). A full day is required to complete the CAT A Verified Tasks & Assessment, and another full day for the CAT B Verified Tasks & Assessment.

For existing practising STMS (with a warrant <12 months expired)
They are eligible to complete the Assessment Tasks (Closure 3) only. The STMS CAT A & B Practising Assessment can be completed in one day.
