Course Information
The TWCTC refresher one-day course, is aimed at learners who have completed the TWCTC or the TWCTC refresher in the last five years. Failure to attend the temporary works refresher prior to the expiry of an existing certificate will require delegates to re-sit the full course.
Essential Site Skills is an established UK provider of the CITB Temporary Works Coordinator Refresher course (TWCTC-R), supporting experienced Temporary Works Coordinators to maintain their competence and remain compliant with industry expectations and BS 5975. Our refresher courses are delivered by industry-experienced professionals, reinforcing key responsibilities and best practice for managing temporary works safely on site.
The two-day Temporary Works Co-ordinator Training Course (TWCTC) and one-day refresher course (TWCTC-R) are designed to help those who have responsibility for managing all forms of temporary works on site. The course seeks to improve the knowledge of this role and the temporary works environment. The development of these courses was supported by several organisations, including the Temporary Works forum and the Health and Safety Executive. Temporary works are safety- and business-critical and require careful co-ordination. An accepted way of achieving this is through the adoption of the management process outlined in BS 5975-1:2024, which introduces the temporary works co-ordinator (TWC) as a key figure. This course explains the role and its overall management context. Temporary works on both smaller and larger sites can be high risk activities. Therefore, understanding the essentials of good risk and safety management, as outlined in BS 5975-1:2024, is relevant for projects of all sizes. The course gives emphasis throughout to the importance of communication, co-ordination, co-operation and competency (the 4Cs), risk management, safety and business relations, allowing the TWC to:
We offer the CITB TWCTC-R qualification course through both in-person sessions and interactive Video Online Learning, catering to individuals working remotely. This training is conducted in a virtual classroom environment, led by our skilled and experienced CITB Site Safety Plus Temporary Works Tutors.
Attendance - Full attendance of the course is mandatory to achieve a pass. Should your internet connection fail during the course for a prolonged period of time, or repeatedly, you may not be able to re-join as requested by the trainer, unless it can be re-established within 5 minutes. This is so general learning is not disturbed for other participants.
Course Publications - This course, including its group work and exercises, is constructed around BS 5975-1:2024. Learners are expected to have a comprehensive understanding of BS 5975-1:2024, and it is recommended that they bring a copy of BS 5975; however, their own organisation’s procedures and guidance on temporary works may be more suitable for reference during the course. In addition, ESS will provide a course workbook that meets the specification required by CITB.
Joining the Video Learning - Our courses are conducted via Zoom, and you will receive your personalised meeting link as part of your course enrolment instructions. We always recommend downloading the App in preparation of the course, you can find instructions here - https://zoom.us/download. Further support using Zoom can be found here – familiarise yourself with this prior to your course - https://support.zoom.us/hc/en-us/p/zoom-meetings-guide
The aim of these courses is to focus on the risk management of temporary works with particular attention on the role of the TWC.
They seek to consolidate and build on the risk management knowledge that learners undertaking this role will have established through other experiences on site (likely in other supervisory and management roles) and focus on how to avoid failure in temporary works by adopting appropriate procedural controls, as outlined in BS 5875-1:2024.
The refresher course is an opportunity for learners who have attended the substantive TWCTC to revise and update their knowledge and understanding.
The TWCTC course will cover the following topics:
The refresher course expects the same underpinning knowledge and understanding to be demonstrated by learners.
There are no formal entry requirements for the TWCTC refresher, but learners are expected to have a working knowledge of the following legislation:
A key issue for temporary works is health and safety, so learners need to be prepared to discuss how health and safety legislation is relevant to temporary works, as well as which Approved Codes of Practice (ACOPs) and guidance notes may assist or contribute to safe practices in temporary works.
Learners need to be prepared to discuss and explore all the core health and safety factors that are integrated into temporary works processes at all stages of a project, from initiation to closure. They will need to have working knowledge of all associated legislation, specifically the Construction (Design and Management) Regulations 2015 in terms of its intention and compliance. Learners must also have a thorough understanding of health and safety principles and understand the importance of risk management, design considerations, inspection and testing and recording and monitoring requirements.
Learners who have achieved a certificate approved against the Health and Safety in Construction Site Supervision standard (such as SSSTS or SSSTS-R) or the Health and Safety in Construction Site Management standard (such as SMSTS or SMSTS-R), will have gained the knowledge to meet these expectations. This is not a mandatory pre-requisite, but learners with these achievements will benefit from having this knowledge before attending the course.
To further support learners, CITB has created a Temporary works awareness eLearning which provides a foundation of the points that will be expanded on in this course. It explores how health and safety legislation plays a pivotal role in temporary works, and how documents which are common to more generic construction activities are a useful aid for planning and the ongoing management and monitoring of temporary works.
Learners may also find it helpful to complete the Temporary works awareness eLearning provided by CITB, which is free to access here.
For the TWCTC refresher, only learners who have completed the TWCTC or the TWCTC refresher in the last five years are eligible to attend.
The TWCTC refresher is a one-day course. Learners must attend the whole day and pass the end-of-course assessment (7.5 hours) to be eligible for certification.
Photographic ID will be requested by the tutor at the start of the course i.e. Driving Licence/Passport.

Assessment
Assessment will be by multiple choice questions at the end of the course. Delegates are also expected to be interactive during the course.
The paper consists of 22 questions, selected by CITB, covering all aspects of the course. This exam paper must be taken at the end of the course.
Each paper has:
The exam paper must be taken at the end of the course. The examination paper number will be notified when the course booking is accepted by CITB.
The exam pass mark is 78% (21 out of 27).
The exam lasts for 45 minutes and must be completed within this time under exam conditions.
The examination is open book: learners are permitted to use their course workbook – which may include any notes made by the learner during the course – for the duration of the exam.
The exam paper forms part of the overall assessment as to whether the learner has successfully achieved the TWCTC.
The trainer review provides a pass or fail based on the learner’s performance and engagement in the course exercises, learner personal review and engagement in the course overall.
The trainer review must be completed before the end of course assessment. If a learner is assessed as failing the trainer review, then they are not permitted to sit the end of course assessment.
If a learner has achieved all of the following, then they may re-sit the examination one further time:
The re-sit may take place on the same day or by attending the final day of another course within a 90-day period (the learner is not obliged to re-do the whole course). The re-sit may be conducted either face-to-face or in a remote setting.
The training provider must make the arrangements with the learner and ensure that the same exam paper is not used twice.
A charge may be made to the learner, however; this fee is left entirely to the discretion of the training provider. The training provider may also recover additional costs from the learner, which should be agreed in advance.
Subsequent arrangements will be at the learner’s own expense.
If a learner fails the re-sit, they must take the TWCTC course again.
When a learner scores less than 63% (17 out of 27 marks) in the final exam, the learner must attend the full TWCTC course again before they are allowed to re-sit the exam.
