In construction, safety leadership is non-negotiable. Whether you’re a new supervisor or aiming to become a site manager, gaining the right health and safety training is a key step in your career. Two of the most recognised qualifications are the SMSTS (Site Management Safety Training Scheme) and the SSSTS (Site Supervisors’ Safety Training Scheme). But which one is right for you?
This guide breaks down the key differences, helps you decide which course matches your current role, and outlines next steps for your construction career.
What Are SMSTS and SSSTS?
Both SMSTS and SSSTS are accredited by CITB (Construction Industry Training Board) and focus on site safety — but they serve different levels of responsibility.

Which Course Is Right for You?
Choosing the right course depends on your current role and your career goals:
- If you’re stepping into a supervisory role (or supervising a small team):
➝ SSSTS is ideal. - If you manage the entire site or multiple teams, handle compliance, or want to move into project management:
➝ SMSTS is the better fit.
Tip: If you’re unsure, start with SSSTS and build experience. You can always progress to SMSTS later.
Career Progression: From SSSTS to SMSTS
Many professionals begin with SSSTS, gain site experience, and then move up to SMSTS as they take on more responsibility. Here’s a typical path:
- Skilled worker with CSCS card
- Complete SSSTS
- Gain site supervision experience
- Progress to SMSTS
- Work towards NVQ Level 6 in Site Management
- Apply for CSCS Black Card (Manager)

Frequently Asked Questions
Is SMSTS harder than SSSTS?
Yes. SMSTS is more in-depth and covers management-level responsibilities. It includes a written project in addition to the multiple-choice test.
Can I take SMSTS without doing SSSTS first?
Yes, if you already work in a site management role or have equivalent experience. You don’t need SSSTS as a prerequisite.
Final Thoughts:
Both SMSTS and SSSTS play a crucial role in raising safety standards across construction sites. Your choice depends on where you are in your career:
- SSSTS helps you step into supervision
- SMSTS prepares you to lead entire sites
