SSSTS vs SMSTS: Which Site Safety Course Do You Need in 2026?
Posted 27 February 2026
In the construction industry, holding the right CITB accredited qualification isn’t just a "nice-to-have"—it’s often a mandatory requirement for site access. If you are looking to step up from the tools or have been told you need a supervisor card to stay on-site, choosing between SSSTS (Site Supervisors Safety Training Scheme) and SMSTS (Site Managers Safety Training Scheme) is your first hurdle.
At Sibbald Training, we’ve helped thousands of workers across West Lothian and Scotland secure their certifications. Here is everything you need to know to choose the right path for your career.

What is SSSTS? (The Supervisor Route)
The SSSTS course is designed for those who oversee workers on the ground. It focuses on the practical side of safety—ensuring site rules are followed and hazards are managed daily.
- Who it’s for: New supervisors or those moving into a "chargehand" or "foreman" role.
- What you’ll learn: How to lead Toolbox Talks, monitor safety behaviours, and understand your legal duties under the Health and Safety at Work Act.
- The "Fast Track" Factor: Because it is only a 2-day course, it is the fastest way to get the credentials needed for a supervisor role on-site.
What is SMSTS? (The Manager Route)
The SMSTS course is a higher-level qualification intended for those with overall responsibility for a site.
- Who it’s for: Experienced site managers, project managers, or senior supervisors looking to advance.
- What you’ll learn: In-depth management of CDM (Construction Design and Management) Regulations, risk assessment planning, and environmental management.
- Career Impact: Most major contractors in Scotland require an SMSTS certificate for anyone in a management position.
Which One Should You Choose?
Choosing can be simple if you look at your current daily tasks:
- Do you lead a small crew and report to a manager? Choose SSSTS.
- Do you sign off risk assessments and manage multiple subcontractors? Choose SMSTS.
- Are you planning to move into management next year? Start with SMSTS to future-proof your career.
Sibbald Tip: Many of our students in Scotland take the SSSTS first as a "stepping stone" before returning a year or two later for the full SMSTS as they progress into senior roles.
Interactive FAQ: What You Need to Know in 2026
Can I take my CITB SSSTS and SMSTS test online?
Yes. We offer both remote "Zoom" classrooms and traditional in-person training at our dedicated Scottish test centres.
What is the difference between an SVQ and these courses?
While SSSTS/SMSTS are "knowledge" certifications, a Scottish Vocational Qualification (SVQ) is a performance-based qualification. Both are often required together to secure higher-level CSCS cards (like the Gold or Black cards).
