SMSTS vs SSSTS: Which Site Safety Course Do You Need?
Overview
SSSTS and SMSTS are often treated as interchangeable site tickets, but they are aimed at different levels of responsibility. SSSTS is built around supervision. SMSTS is built around managing construction work. The right choice depends on the job you are moving into, not which certificate sounds more senior.

SSSTS is for supervisors; SMSTS is for managers
SSSTS, the Site Supervision Safety Training Scheme, is designed for people who supervise workers and work activities. That can include working foremen, team leaders and new supervisors who need to understand their safety duties.
SMSTS, the Site Management Safety Training Scheme, is designed for site managers and people who plan, monitor and control work across a construction site. It covers a wider management view because the role carries wider responsibility.
CITB's current Site Safety Plus scheme rules list SSSTS as a two-day course and SMSTS as a five-day course. Duration is only part of the decision. The important question is whether the course matches the work you are expected to do.
Which course fits common construction roles?
Assistant site manager roles sit in the middle. Some employers accept SSSTS while the person is developing. Others require SMSTS because the assistant covers the manager and holds wider duties. Read the responsibilities and ask the employer rather than assuming from the word assistant.
If you are comparing assistant roles, use the assistant site manager salary guide to judge responsibility and package together.
What these courses do not prove
An SMSTS certificate does not automatically give you a CSCS Black Manager card. Card routes depend on the relevant occupation and recognised qualification. Likewise, an SSSTS certificate does not turn a new operative into an experienced supervisor.
Be wary of anyone selling either course as a guaranteed promotion. The strongest route combines training with evidence that you have already led work safely, kept records, communicated clearly and dealt with problems on a live project.
What to check before paying for training
Then ask the provider whether the course is the current CITB Site Safety Plus course, what is included in the price and what you need to attend. If your employer is supporting the move, ask whether they will fund the course or release you for it.

Step-by-Step Career Path
Start with the role you actually want
Look at current adverts for supervisor, foreman, assistant site manager and site manager roles in your area before choosing a course.
Choose SSSTS for supervisory responsibility
SSSTS is designed for people supervising teams and work activities on construction sites.
Choose SMSTS for site-management responsibility
SMSTS is designed for site managers and people with wider responsibility for planning, monitoring and controlling construction work.
Check the employer requirement
