CITB Site Supervisors Safety Training Scheme (SSSTS)
CITB SSSTS Training for Construction Site Supervisors
2-day course | Classroom | Certificate valid 5 years
The CITB Site Supervisors’ Safety Training Scheme (SSSTS) is a nationally recognised qualification designed for supervisors and those preparing to move into a supervisory role within the construction industry. The course provides a clear understanding of health and safety responsibilities, helping supervisors contribute effectively to safe, compliant site operations.
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
- 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.
