Both courses are CITB-backed and widely required, but they serve very different roles. We break down the key differences, who each course is designed for, and how they fit into your CSCS card journey.
The SMSTS and SSSTS are two of the most widely recognised construction safety courses in the UK. Both are developed by CITB and both are frequently specified by clients and contractors — but they're designed for very different roles.
SSSTS — Site Supervisors' Safety Training Scheme
Who it's for: Frontline supervisors, foremen, charge-hands, and gang leaders.
Duration: 2 days
What it covers:
- Legal duties and responsibilities of a supervisor
- Risk assessments and method statements
- Accident reporting and investigation

- Emergency procedures
Cost: Typically £200–£350 per person, depending on provider.
Certificate validity: 5 years (renewal via 1-day refresher course)
