In terms of accessibility and flexibility this Environmental , Health and Safety course was great as I am an international student. This course in Environmental Health and Safety allowed me to obtain a formal and recognised OH&S qualification sooner rather than later, which is a refreshing change, in comparison to other institutions that I've encountered. Overall it was worth it from my perspective.

We would advise any person who is new to environmental, health and safety to start at an entry level course. Some of the higher level certification courses in Environmental, Health and Safety have strict entry criteria and usually require a minimum of 2 years work experience or some type of Certification in Environmental, Health and Safety at level 5 or 6 (Ireland) or level 3 (England).

The starting point is to check whether you have previously completed any short courses in health, safety and environmental. If you have completed  1 or 2 day courses in Manual handling, Abrasive Wheels, Risk assessments, Environmental or related areas, then you would be eligible to apply for a higher level environmental, health and safety online course. 

At CMI, every environmental health and safety certification course sits at a particular level. The levels of our Environmental Health and Safety courses are set and recognised by the Regulated qualifications framework (RQF) England and/or the National framework of qualifications (NFQ) in Republic of Ireland.  The higher the level, the higher the health and safety job role you would automatically qualify for. Please request a copy of our guide to Environmental, health and safety roles and qualifications which indicates roles, and typical salary range you can achieve  based on the Environmental, health and safety course you chose.
