Quick answer

What is the SSSTS Refresher course?

The SSSTS Refresher is the CITB one-day course that renews a Site Supervisor Safety Training Scheme certificate. It brings construction supervisors up to date with current health and safety law and good practice, and extends the CITB Site Safety Plus certificate for a further five years. It must be completed before the existing certificate expires.

Renews an SSSTS certificate for a further five years
One day, 7.5 hours, with full attendance required
Updates supervisors on current law and good practice
Must be taken before the existing SSSTS certificate expires
An SSSTS certificate is valid for five years. The SSSTS Refresher is the CITB one-day course that renews it without a supervisor having to repeat the full two-day course. Over 7.5 hours it brings construction supervisors and team leaders up to date with current health and safety law, changes in regulation and guidance, risk assessments and method statements, and the supervision and monitoring expected of the role. The course is for delegates who already hold a Site Supervisor Safety Training Scheme certificate, and delegates are continually assessed through the day. Full attendance is mandatory. The refresher must be completed before the existing certificate expires: if the certificate is allowed to lapse, the refresher can no longer be used and the full two-day SSSTS course must be taken again. KeyOstas delivers the SSSTS Refresher in-company or as a scheduled course, in the classroom or as live online instructor-led training.
