If you work in construction, you will often see the terms SMSTS and SSSTS when looking for CITB training. Both qualifications help improve safety standards on site, but they prepare you for different levels of responsibility. Understanding these differences will help you choose the course that matches your current role and future career goals.

It covers the essential knowledge supervisors need to keep workers safe, including health and safety law, hazard awareness, risk control and encouraging safe behaviour on site. SSSTS helps new and existing supervisors understand their duties and handle everyday safety concerns confidently.
