The International Certificate in Occupational Hygiene (ICertOH) demonstrates technical knowledge and practical skills in identifying health hazards, assessing occupational exposure and testing control measures. It is suitable for technicians and technologists who carry out measurements and testing in workplaces. The qualification has been designed so that it can be recognised by national associations as contributing to their own requirements for accreditation.
Intermediate Level Modules
You can work towards the ICertOH by studying OHTA Intermediate modules. To obtain the ICertOH, you must complete six modules, including four core subjects and two others chosen from three options:
- W501 Measurement of Hazardous Substances
- W503 Noise - Measurement and its Effects
- W505 Control of Hazardous Substances
- W507 Health Effects of Hazardous Substances
- W502 Thermal Environment
- W504 Asbestos and Other Fibres
- W506 Ergonomics Essentials
Progression Towards the ICertOH
Once you have completed six modules, you can progress to the award by completing a Personal Learning Portfolio. During the courses you are required to demonstrate that you can carry out basic practical assessments under the supervision of course tutors. To meet the aims of the intermediate level courses and for you to reach the required level of technical and practical skill, you will continue to develop those skills through practical experience in the work environment. You will need to collect evidence which demonstrates you have applied your knowledge in practical situations. This will be documented in your Personal Learning Portfolio. Full details on completing your Personal Learning Portfolio can be found in the Qualification Guide. You should start compiling your portfolio as early as possible after completing your first OHTA course. Once you have completed your portfolio you can apply for your intermediate level interview for the award of the ICertOH.

Other Routes to the ICertOH
For students with different needs, there is an alternative way to achieve the ICertOH:
- By taking an approved university degree course which provides exemption from studying the modules. Normally the student will still need to complete the Personal Learning Portfolio.
Anyone without prior training or experience of occupational hygiene is strongly advised to study the Foundation level before attempting the Intermediate modules. To help with your decision, we suggest you review the syllabus and student manual for the Basic Principles course.
