CITB SSSTS training for construction site supervisors

SSSTS focuses on the practical application of health and safety law on site, equipping delegates with the knowledge and confidence to supervise work safely, communicate expectations clearly, and take appropriate action when unsafe conditions or behaviour are identified.

Who is the SSSTS course for?

This course is ideal for site supervisors, team leaders and gangers, foremen, chargehands, those preparing to step up into a supervisory role, and anyone with responsibility for supervising work on construction sites.

SSSTS is often a minimum requirement set by principal contractors for supervisory roles and is a key progression step between operative-level training and site management qualifications such as SMSTS.

What the SSSTS course covers

The full CITB SSSTS syllabus is delivered across two classroom-based training days and includes:

  • An overview of health and safety law and how it applies to supervisors
  • The supervisor’s role in maintaining site safety
  • Understanding responsibilities for controlling work activities
  • Using risk assessments and method statements effectively
  • Delivering effective site inductions and toolbox talks
  • Monitoring site activities and identifying unsafe practices
  • Taking action when health and safety standards are not met
  • Communicating clearly with operatives, managers and contractors
  • Encouraging positive safety behaviour and site standards

The course uses practical examples, discussion and real-world scenarios to ensure learning can be applied immediately on site.

Course materials and assessment

What’s included:

  • All required course materials
  • Tutor-led discussions and practical exercises
  • Support from experienced trainers throughout the course

Delegates are assessed through:

  • A multiple-choice examination
  • Tutor-reviewed participation during the course

Successful delegates receive a CITB SSSTS certificate, valid for 5 years.

To maintain certification, an SSSTS Refresher (SSSTS-R) must be completed before the certificate expires. If it lapses, the full SSSTS course must be taken again.

Frequently asked questions

How do I find and book a course?
Tell us the course you need and your availability, and one of our course advisors will find the most suitable accredited course for you and handle the booking. Rather than list every date here, we match you to a course that fits, and reply the same working day by phone or email, whichever you ask for.
Can you help with group or on-site training?
Yes. For six or more delegates a private group course is often more cost-effective. Ask a course advisor and we’ll arrange a group course at your premises or a nearby centre.
