What is a REHS/RS Credential?
The REHS/RS is the premiere NEHA credential. It is available to a wide
range of environmental health professionals. Individuals holding the
REHS/RS credential show competency in environmental health issues,
direct and train personnel to respond to routine or emergency
environmental situations, and frequently provide education to their
communities on environmental health concerns. The advantages of NEHA's
REHS/RS registration program are: demonstrate your competency and
capabilities in the environmental health field, the continual update of
the REHS/RS examination and study guide based on an ongoing assessment
of the environmental health field, and the tracking of individuals
continuing education by NEHA.
In 2013, the National Environmental
Health Association undertook the process of a Job Task Analysis to
refresh and update the REHS/RS examination. Subject Matter Experts were
used to develop a new, up-to-date, relevant exam.
NEHA will be releasing this new
exam on July 13, 2014, at the
Education Conference in Las Vegas. This information reflects the
changes to the exam content and suggested references.
