Since 1937 we have 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.

Value of a NEHA Credential

Our longstanding 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 their subject matter and adhere to a code of ethics.
