Two CITB tickets, similar names, and they are not interchangeable. It is the question we get asked most, so here is the short version.
SSSTS is the supervisor's ticket. Two days, for the people who lead a team on site but are not running the whole job: gangers, foremen, chargehands, team leaders.
SMSTS is the manager's ticket. Five days, for site managers, agents and project managers, the people accountable for the site as a whole.
The rule of thumb: if they supervise the work, SSSTS. If they are accountable for the site, SMSTS. There is no requirement to hold SSSTS first, so anyone stepping into management can go straight to SMSTS.
Both certificates last five years, and both are renewed with a refresher before they expire rather than sitting the full course again.
We have written the longer version, with the side by side comparison and what each course covers:
