Advance Your Career with a NEHA Credential

Receive the recognition you deserve for your expertise by earning one of the environmental health credentials offered by the National Environmental Health Association (NEHA). Founded in 1937 by practitioners who wanted to establish a standard of excellence for the profession, that standard has come to be known as the Registered Environmental Health Specialist/Registered Sanitarian (REHS/RS) credential. Since that time, NEHA has developed additional credentials that evidence mastery of specialized knowledge. NEHA is striving to make the credentialing process as convenient as possible.

These marks of distinction assist both employers and the credentialed individual. Employers can be confident that a credentialed employee has acquired the knowledge necessary to competently perform their duties. Credentialed individuals may find positions easier to obtain and may increase their earnings.
