The international qualifications scheme allows you to study occupational hygiene at the level that suits you 

With a modular design, you can take the courses you need when you want

This gives you the flexiblity to build on your existing qualifications and to fit in more easily with your job demands.  You can start from the Foundation level, and progress through Intermediate level to Advanced level. 

How the scheme works

Examining boards from across the world have come together to agree a common framework of qualifications.  It allows qualified hygienists recognition for their qualifications in the countries where they practice.

OHTA provides training materials and Approved Training Providers to help you qualify.  You can review and download training materials free of charge from the OHLearning website.  You can also identify approved providers of training courses and find out when and where courses are being held.

Please note that international qualifications cover the core science and practice of occupational hygiene; they do not cover the details of local legislation or local custom and practice.  Hence national associations may impose additional requirements before recognising hygienists with international qualifications to practise in their country.  

The scheme is administered for OHTA by the Qualifications Group.

Prior learning

There are no formal educational requirements for people wishing to study any of the international qualifications. However, the OHTA courses do require some knowledge of chemistry, mathematics, statistics, engineering and biology. Students without a strong educational background in these areas may find the courses very difficult. Recommendations for prior learning are given at each of the different qualification levels so that you can top up your knowledge before taking the courses.
