SSSTS is aimed at people who supervise others on site. If you hand out work, check that it is done safely and report to a site manager, contractors will often ask you to hold it.

It is also a common first step for tradespeople moving into a supervisory role, because it gives you the language and tools to run safe work.

Roles usually asked for SSSTS

Team leaderRuns a small team on maintenance or fit-out work
New supervisorNeeds a recognised safety course for the role
2 daysfull course
5 yearscertificate validity
1 dayrefresher before expiry

What the course covers

You learn how to carry out and brief risk assessments and method statements, run toolbox talks, monitor safe working, and deal with common hazards such as work at height and excavations. Read what to expect on an SSSTS course for more detail, and what a toolbox talk is if you are new to running them.

Building towards a gold card? SSSTS is useful training, but the gold Supervisory card needs a Level 3 or 4 supervisory NVQ. See how to get a gold CSCS card.

Mistakes people make with SSSTS

The biggest mistake is assuming SSSTS is a lighter version that any worker can take for their CV. It is aimed at people who already supervise, or are about to. Without that experience you may struggle with the exercises.

  • Booking it instead of SMSTS. If you are planning work, not just supervising it, contractors may ask for SMSTS instead.
  • Forgetting the expiry date. The certificate lasts five years. Book the one-day refresher before it runs out.
  • Not preparing. You will discuss real site scenarios. Thinking about the risks on your own sites beforehand helps.
  • Expecting a card upgrade. SSSTS supports a Gold supervisory card, but you also need a supervisory NVQ or equivalent.

Your next steps

  1. Ask your employer which supervision certificate your sites require.
  2. Pick classroom or online delivery, and check you can attend both days in full.
  3. Bring examples from your own work. The course is more useful when you link it to your sites.
  4. After you pass, consider an NVQ Level 3 in occupational work supervision for a Gold card.
  5. Set a reminder to refresh before the five years are up.
