CIOB Level 3 Diploma in Site Supervisory Studies

We have developed our own set of courses and qualifications to aid site operatives and skilled tradespeople and apprentices progress into site supervisory and management roles, and into professional membership. These courses are at Levels 3 and 4 on the Regulated Qualifications Framework (RQF) - the national credit transfer system for education qualifications in England and Northern Ireland (Wales and Scotland have slightly different, but basically interchangeable, systems).

CIOB Level 3 Diploma in Site Supervisory Studies

This helps you to develop the knowledge and practical skills to enable you to supervise construction projects safely and efficiently.


The diploma programme is split into six units. Although units will vary in length the prescribed total qualifications time is 600 hours, which comprises 192 guided learning hours and 408 personal study hours. There will be a formal evaluation at the end of two specified units for the award of the Diploma. Performance is assessed by project work and assignments. Please check the syllabus for more information.

New Site Supervisor Syllabus 2020

In line with the requirements of our regulators, Ofqual, we have reviewed our qualifications specifications. The Level 3 Certificate in Supervising Construction Works to Existing Buildings and Structures (2 units) is no longer available and has been removed from qualifications registers. The Level 3 Diploma in Site Supervisory Studies required a light touch review of the content, looking at the learning outcomes and assessment criteria in comparison to that of the level 4 qualification. The duration of the qualification remains the same as the old 2015 syllabus, but the main changes are that the personal study hours and the total qualifications time have been increased to reflect the content, so therefore the credit has been increased to reflect this. The 2015 syllabus must now have no further registrations to be taken as of 31st March 2021, and the certification end date is set for 31 December 2022.
