A full CITB SMSTS course usually takes five days, or around 37.5 hours of training. Depending on the provider, it may be delivered as five consecutive days, one day per week, split sessions, classroom training or live remote learning.
For learners who want to understand site management safety before committing to a full route, Learnera’s online SMSTS Course can support CPD learning in areas such as risk assessment, CDM Regulations and site safety responsibilities. However, employer requirements can vary, so always check whether you need a full CITB SMSTS certificate, a refresher course or CPD knowledge building.
Key points:
- A full CITB SMSTS course usually takes five days.
- Day-release formats may spread the course over several weeks.
- The SMSTS Refresher usually takes two days if your certificate is still valid.
How long is the full SMSTS course?
The full Site Management Safety Training Scheme, known as SMSTS, is normally a five-day course. It is designed for people who manage or are preparing to manage construction site work.
The course takes this long because it covers serious site management topics. These can include health and safety law, CDM Regulations 2015, risk assessments, method statements, site setup, working at height, occupational health, environmental issues and managing site hazards.
So, when people ask, “Can I finish SMSTS quickly?” the honest answer is that the full recognised route is not usually a one-day or few-hour course. It needs time because site managers carry real responsibility.
Does the SMSTS course have to be five days in a row?
Does SMSTS Have to Be Five Days in a Row?
Not always. The training time is still usually five days, but providers may arrange those days in different ways to suit working learners.
Five Consecutive Days
Complete the course in one working week, often Monday to Friday.
Day-Release
Attend one training day each week over a longer calendar period.
Split Format
Complete part of the course one week and the remaining days later.
Five Consecutive Days
This format usually runs from Monday to Friday. It suits learners who want to finish quickly and can take a full week away from work.
Consecutive, day-release and split formats usually contain the same five training days. The main difference is how those days are arranged on your calendar.
Is online SMSTS shorter than classroom SMSTS?
A live online CITB SMSTS course is not usually shorter than classroom SMSTS. If it is the full course, it still normally follows the five-day structure.
The difference is how you attend. Classroom training takes place at a venue, while remote training is usually delivered live by a trainer through an online classroom. You still need to attend, take part and complete the required learning activities.
Self-paced CPD learning is different. It may be shorter and more flexible, but it is mainly for knowledge building and professional development.
How long does the SMSTS Refresher take?
The SMSTS Refresher usually takes two days. It is for people who already hold a valid SMSTS certificate and need to renew it before it expires.
This is where many learners get caught out. If your certificate expires, you may not be able to take the refresher. You may need to retake the full five-day course instead.
That is why it is sensible to check your expiry date early and plan your refresher before the deadline.

What is the biggest mistake when comparing SMSTS course lengths?
The biggest mistake is thinking every SMSTS-style course is the same. A full CITB SMSTS course, a two-day refresher and an online CPD course all serve different purposes.
Before choosing, ask yourself one simple question: do you need a specific CITB certificate for work, or do you want flexible CPD learning to improve your understanding? Once you know that, the right route becomes much clearer.
