REHS/RS Credential

A Professional Credential From NEHA

Since 1937 NEHA has been leading the way for practitioners to achieve a set of defined competencies, evidenced through testing and maintained through continuing education. These benchmarks of excellence have become the gold standard in recognizing those who are uniquely equipped to handle the wide breadth of environmental health issues. NEHA’s long-standing history in credentialing means that our standards are high and that individuals with a NEHA credential have mastered a body of knowledge and acquired practical experience to perform relevant work responsibilities.

As an impartial, third-party endorsement of an individual’s professional knowledge and experience, a credential stands in support of a candidate’s resume and professional references. It serves as verification that a professional has achieved a baseline level of competency in his or her subject matter.

What is an REHS/RS Credential?

No issues are more important to the communities in which we live and work than clean air, safe food, and potable water. An individual with an REHS/RS credential has the skill set to ensure that these basic community necessities are met as well as to manage other critical functions such as emergency response, vector control, sewage sanitation, hazardous material handling and more.

The REHS/RS is the most prevalent NEHA credential and professionals demonstrate competency in an impressive range of environmental health issues, directing and training personnel to respond to routine or emergency environmental situations, and providing education to their communities on environmental health concerns. In addition, REHS/RS credential holders are key members in ensuring communities are in compliance with local, state and federal environmental health regulations.
