The Professional Development activities of the Institute relate to the procedures for new professionals and to the ongoing development of those already qualified.

For those studying for and training to be an Environmental Health Officer or Food Safety Officer the Institute arranges and delivers the examination for the professional qualification, and awards that qualification to successful candidates.

Once qualified, professionals, both EHOs and non-EHOs can seek to comply with the REHIS Continuing Professional Development (CPD) Scheme.

The Institute is the only organisation in the world which can confer the title ‘Chartered Environmental Health Officer’. Chartered status is the highest possible professional status and recognises an individual’s professional qualifications, training, experience within, and commitment to, environmental health practice.

Chartered Environmental Health Officer members may use the post nominal letters Ch.EHO MREHIS or Ch.EHO FREHIS if they are a Fellow of the Institute.

The Institute arranges and delivers training events, both as Professional Courses, arranged by the Institute office, and Training Events, arranged through the two Centres of the Institute, Northern and Southern.

Professional Courses are scheduled by the Courses Co-ordinator and most commonly hosted by the REHIS Council member with responsibility for the respective subject area.

Training Events are planned and arranged by the Committees of the Northern and Southern Centres.

The Institute also seeks to promote events delivered by other organisations which may offer learning and development opportunities to those working in Environmental Health.
