As part of its Site Safety Plus Scheme, the CITB offers both the SSSTS and SMSTS courses to raise health and safety standards across UK construction sites. While the SSSTS course is designed for site supervisors, the SMSTS course is aimed at site managers and those progressing into management roles. In this guide, we’ll break down the key differences between the two and help you decide which qualification best suits your role and career goals.
What Is the SSSTS Course?
SSSTS stands for Site Supervisors’ Safety Training Scheme. It’s a recognised health and safety qualification designed for individuals who have, or are about to take on, supervisory responsibilities within the construction industry. Completing the SSSTS course shows that a supervisor understands their legal duties, can effectively manage health and safety on-site, and can ensure their team follows safe working practices.
