NEHA Announces Passing Score for New REHS/RS Exam
The National Environmental
Health Association (NEHA) will be unveiling the new version of its
on July 13, 2014, at the 78th Annual Educational Conference &
Recently, NEHA worked with Professional Testing Inc. (PTI) and a
group of subject matter experts to determine the new passing score
for the revised exam.
From that meeting, the following was determined:
In an effort to standardize the score reporting process across
all of NEHA’s examination programs NEHA has decided to implement
scaled scoring. Therefore, in the near future, all NEHA
examinations will have a standard passing score of 650 no matter
the examination program or form.
Beginning July 13, 2014, the NEHA REHS/RS examination will
report scores using scaled scores that range from 0 to 900 with
a passing score of 650. The raw passing score is mathematically
transformed so that the passing scaled score equals 650. This
process is similar to the way one adjusts Celsius and Fahrenheit
temperature scales. While the values may differ the temperatures
are the same. For example, water boils at the same temperature
regardless of the scaled used.
Candidates who pass the examination will earn scaled scores of
650 and above, and those who fail will earn a scaled score
between 0 and 649. A scaled score is NOT a percentage score.
In summary, a scaled score is merely a transformation of a raw
score. Scaling is done to report comparable results when forms
and raw passing scores vary over time.
consists of a total of 250 multiple-choice questions. The exam is
split into two parts of 125 questions each. Candidates are given a
total of four (4) hours to complete the entire exam or two (2) hours
for each part with a short 15-minute break in between. Of the 250
items, 225 will be scored. The remaining 25 questions will be
unscored, pilot questions. Those items will not be called out within
