In 2013, the National Environmental Health Association undertook the process of a Job Task Analysis to refresh and update the HHS examination. Subject Matter Experts were used to develop a new, up-to-date, relevant exam.

NEHA will be releasing this new exam on February 1, 2015 for computer and paperbased testing. This Candidate Information Brochure reflects the changes to the exam content and suggested references.

For as long as NEHA has existed, NEHA has strived to elevate the standing and respect accorded to those who practice environmental health. One of the mechanisms used by professional societies like NEHA to achieve such a goal is the one of credentialing. Through a professional credential, one evidences to both their employer and to the public they serve that they are competent to carry out the duties and tasks expected of them. Such a mark of distinction also serves the practitioner inasmuch as the effort expended to gain such a credential often leads to higher levels of individual compensation and regard, as it should. NEHA’s mission is to advance you — pure and simple. Few professional fields are growing and changing as rapidly as environmental health. Attainment of the HHS credential demonstrates professional direction, achievement and the knowledge to carry out functions and duties of a technical nature in a responsible manner.

The HHS exam tests your understanding of the connection between health and housing, enabling you to take a holistic approach to identify and resolve problems that threaten the health and well-being of residents and was developed in partnership with the National Center for Healthy Housing (NCHH).
