Which is Higher, SMSTS or SSSTS?
In construction, training qualifications play a vital role in maintaining safety and professionalism across all site operations. Two of the most recognised CITB courses are SMSTS (Site Management Safety Training Scheme) and SSSTS (Site Supervisor Safety Training Scheme). While they sound similar, they’re designed for very different levels of responsibility. So, which is higher- SMSTS or SSSTS? In short, SMSTS is the higher-level qualification. It’s aimed at managers rather than supervisors.

Understanding the Difference Between SSSTS and SMSTS
The SSSTS course is designed for site supervisors, those who directly oversee workers and ensure that day-to-day operations follow health and safety protocols. It provides the fundamental skills needed to monitor small teams and maintain compliance with legislation.
On the other hand, the SMSTS goes further. It’s intended for site managers and project leaders who are responsible for developing, implementing, and enforcing safety management systems. Rather than just supervising tasks, SMSTS-trained managers plan and oversee entire projects, ensuring legal compliance across multiple trades and contractors.
SMSTS: A Higher Level of Responsibility
Because the SMSTS qualification is targeted at those in senior roles, it involves a greater depth of knowledge. The course covers a wide range of advanced topics, including:
- Construction design and management (CDM) regulations
- Legal duties of site managers
- Risk assessment and method statement development
- Site setup and welfare requirements
- Managing subcontractors and multi-trade operations
By contrast, the SSSTS course focuses more on immediate supervisory duties, such as monitoring workers’ safety behaviours and enforcing toolbox talks.

Conclusion: Which is Higher, SMSTS or SSSTS?
The Site Management Safety Training Scheme is higher than SSSTS, both in terms of responsibility and complexity. While SSSTS equips supervisors to oversee day-to-day site activities safely, SMSTS prepares managers to plan, monitor, and control safety across entire construction projects.
