CITB SSSTS Classroom Course

The CITB SSSTS (Site Supervisors’ Safety Training Scheme) is the recognised health and safety qualification for construction site supervisors, team leaders and first-line managers across the UK. The two-day course forms part of the CITB Site Safety Plus programme and is required by BuildUK for supervisors working on their sites.

The SSSTS qualification gives holders a solid understanding of health and safety legislation, risk assessment, CDM Regulations and their legal responsibilities as site supervisors. It is widely recognised throughout the UK construction industry and is the standard stepping stone before the SMSTS for those moving into site management roles.

What does SSSTS stand for?
SSSTS stands for Site Supervisors’ Safety Training Scheme. It is a CITB-developed two-day training course designed to ensure site supervisors have the health and safety knowledge and legal understanding to fulfil their supervisory responsibilities on construction sites. The qualification forms part of the CITB Site Safety Plus programme.
Who should attend the SSSTS course?

The SSSTS is designed for anyone in a supervisory role on a construction site or moving into one:

  • Site supervisors and team leaders
  • First-line managers and forepersons
  • Construction workers stepping into supervisory roles
  • Those responsible for overseeing health and safety on site
  • Those working towards the SMSTS qualification

SSSTS is required by BuildUK for supervisors working on their members’ sites and is widely specified in construction job descriptions and contract requirements.

What does the SSSTS course cover?

The course covers the key areas of construction site safety relevant to supervisors:

  • The Health and Safety at Work etc. Act 1974 and related legislation
  • The UK legal framework and Approved Codes of Practice
  • Construction Design and Management (CDM) Regulations 2015
  • Risk assessments and method statements
  • Causes and types of construction accidents
  • Site inductions and toolbox talks
  • Proactive and reactive safety monitoring techniques
  • Supervising high-risk activities — working at height, confined spaces, demolition and excavations
  • Occupational health, fire safety and contractor management
  • Environmental awareness on construction sites
What is the difference between SSSTS and SMSTS?
SSSTS is a two-day course for site supervisors with day-to-day supervisory responsibility on construction sites. SMSTS is a five-day course for site managers with full management responsibility for health and safety. SSSTS is the standard entry-level qualification for supervisors; SMSTS is required for those moving into site management roles. Many construction professionals complete SSSTS first and progress to SMSTS as their career develops. See our article on SSSTS or SMSTS — which do you need?
SSSTS assessment and certification

Assessment includes a multiple-choice exam, class discussions and a short case study. There is no pre-course assignment or written submission required.

  • Certificate validity: 5 years from date of award
  • Awarded by: CITB
  • Re-sit: Available within 90 days if the exam is not passed (additional fee applies)
Training materials and publications
All SSSTS delegates receive access to the official CITB Site Safety Plus publications, available in printed, CD or online format depending on the training provider. Check your joining instructions to confirm whether hard copies are included in your course fee.
SSSTS course prerequisites

There are no formal qualification requirements for the SSSTS course. The following conditions apply:

  • Valid photographic ID is required (passport or driving licence)
  • A good understanding of written and spoken English is necessary — translators are not permitted
  • Parental consent is required for delegates under 18

The CITB Health and Safety Awareness course is a helpful foundation but is not a formal entry requirement.

Can my employer claim CITB funding towards SSSTS?

Construction employers registered with the CITB Levy may be able to offset part of the SSSTS course cost. From January 2026, short course funding moved from the old direct grant model to CITB Employer Networks, with up to £115 available per SSSTS delegate for eligible employers.

Whether your employer can access this funding depends on their CITB registration status and regional network availability — it is worth asking your training or HR manager before booking. Envico works with CITB-approved providers across the UK, so once funding eligibility has been confirmed, you can book your course here in the normal way.

How do I renew my SSSTS certificate?
To maintain your SSSTS qualification you must complete the SSSTS Refresher course before your current five-year certificate expires. If the certificate lapses, the full two-day SSSTS course must be retaken rather than the shorter refresher.
