Proficiency Modules

The Proficiency Modules cover both theory and practical training in specific subjects, and are aimed at those needing to demonstrate a level of proficiency to carry out the area of work covered by the Module.

These examinations are usually taken at the end of training courses run by independent Course Providers who are registered with BOHS. It is possible to sit (or re-sit) the examination only, as an external candidate. In either case, all bookings and payments are made directly with the Course Providers and not through BOHS.

In most cases, the examination includes a written paper and a practical assessment and candidates must pass both elements, and for some of the Modules, the qualification is not complete without a further supporting submission of a report.

How to study

Students can choose to take one or more of these courses, aiming for stand-alone qualifications, or groups of qualifications in areas of specific interest and relevance, such as with aspects of asbestos management, or LEV or legionella management.

Any candidate who has passed all five P401 to P405 asbestos Proficiency Modules will be deemed to have achieved the equivalent of the Occupational Hygiene Module S301 Asbestos and Other Fibres.

Any candidate who has passed P701, P702 and P703 noise and vibration Proficiency Modules will be deemed to have achieved the equivalent of the Occupational Hygiene Module M104 Noise and an Introduction to Vibration.

Three refresher examinations are also available for particular areas of asbestos management where guidance recommends regular re-training; these cover P402 and P404 and are listed in the table above.


There are no formal educational requirements for people wishing to study for any of the Proficiency Module qualifications. However, the courses do require some basic maths and science knowledge and relevant practical work experience, and students without this background may find the courses and examinations difficult. Recommendations for levels of prior knowledge are given on each syllabus.

Candidates wishing to take any of the Asbestos Refresher examinations must already hold the relevant full Proficiency Module qualification, or the Certificate of Competence in Asbestos.
