Track A – Environmental Health Degree
Track. You must be able to answer YES to all the questions for
Track A. If you answer a question with a “No,” proceed to Track B.
1. Do you have a Bachelor’s
degree, Master’s degree or PhD from a college or university in the

Information Brochure section
2. Is your degree in
3. Is your school and degree

If you answered “Yes” to all three questions
above, you can apply on Track A. You will not need to submit proof
of work experience.
Track B – Bachelor’s Degree Track.
You must be able to answer YES to all questions for Track B. If you
answer a question with a “No,” proceed to Track C.
1. Do you
have a Bachelor’s degree, Master’s degree or PhD from a college or
university accredited in the United States? Your degree can be
in any subject. For foreign degrees or diplomas, see the
Information Brochure section
2. Do you have 30 semester
hours (or 45 quarter hours) of college credit in basic science
coursework? Basic sciences include Life Sciences, Natural Sciences,
Physical Sciences or Health Sciences.
3. Do you have credit for a
college level Math or Statistics class?
4. Do you have two years or
more experience working in environmental health*? Work experience
should be full-time paid work.
* Eligible areas of environmental health
include general environmental health (including inspections,
environmental microbiology, and contamination control), food
protection, wastewater, solid and hazardous waste, potable water,
inspections of facilities, institutions and licensed establishments,
swimming pool inspections, radiation, occupational safety and
health, healthy housing, indoor air quality, and disaster and
Track C – “In Training” Track. On
Track B above, if you said YES to questions 1, 2, and 3 but you do
NOT have two years of work experience in environmental health, you
can apply on the “In Training” Track. You would choose REHS/RS-In
Training (I.T.) on the application. You will not be required to
submit proof of work experience. If you pass the exam, your
certificate will say, “REHS/RS – In Training.” You will then have 3
years to obtain 2 years of work experience. Once you have acquired
that experience, you can qualify for the full REHS/RS certificate by
notifying NEHA and submitting proof of work experience. If you do
not obtain the 2 years of work experience, your “In Training” status
will expire and you risk losing the credential and may have to
reapply and retake the exam.
On Track B above, if you said NO to question
1 (and you do not have a foreign degree either) OR
said NO to question 2 (science hours) OR question 3
(math class), then your education does not meet the requirements for
the REHS/RS credential set by the NEHA Board of Directors.
The Board of Directors has ruled that NEHA
cannot accept work experience in lieu of college coursework.
