The following list is a work in progress; an attempt to catalog and identify all designation-type certifications relating to environmental, safety and occupational health professional areas of practice. Designation-type certifications, for the purposes of this catalog, are those that have established sets of initials (e.g., CET, CIH, CSP, CHMM) that certified individuals are permitted to use after their name to indicate the certification and/or areas of expertise. The list also includes certain state licenses having rigorous qualifications and examinations, and which are widely recognized and/or commonly associated with designation-type initials, such as California's Registered Environmental Auditor (REA). The list (with a few exceptions) does not include study programs that offer certificates of completion or certificates based on the completion of specified courses that do not also include a comprehensive examination, a minimum of relevant professional experience, or continuing professional development requirements. These also do not (normally) convey a formal designation.
Please help us build, validate and maintain this list. We include links to certifications on the list for which we have enough information to identify the proper title and sponsoring organization.
For those designations that are not defined, or for which we do not know the sponsoring organization, clicking on the initials launchs an e-mail to NESHTA. Please use this link to provide any useful information on the certification. If you know of an EH&S designation that is not on this list, please send us the details using this link.
