Environmental Technician (RET)
For as long as NEHA has existed, NEHA has strived to elevate the
standing and respect accord 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 RET credential proves a
standard knowledge base which allows technically qualified personnel to
be recognized for their proven expertise.
