[RE-wrenches] NABCEP Test

Thu Mar 31 22:14:45 PDT 2011

This is what Ezra Auerbach, Executive Director of NABCEP, has to say on the
matter:

Hi Nick et al,

A couple of clarifications. It has always taken a month or more for NABCEP
to issue score reports on installer exams. Entry Level results tend to be
quicker and this might be a source for confusion.

I'll do my best to explain the passing score process. There is no set
percentage or number of correct answers. Each exam is different from the
last and is a mix of "field proven" and new questions. We use professional
psychometricians for  exam design and evaluation. They work with the subject
matter experts on the exam committee. After each exam they all meet and
review the performance of the exam with particular focus on new questions.
Sometimes a question performs poorly which is to say a very high percentage
of candidates who otherwise did well got it wrong. This sort of item is
flagged for committee review. They sometimes decide it was a poor question
and choose not to score it which is one reason for variance between exams.

The Psychometrician uses a well established and accepted statistical review
protocol that is designed to ensure consistency across multiple exam
administrations. They then present their professional recommendations to the
Board for their acceptance. This again is standard procedure for "Board"
exams.

In summary NABCEP follows well established internationally recognized
scoring protocols that are fully psychometrically defensible which is part
of the reason our PV Installer Certification has received accreditation by
ANSI to their 17024 standard for personnel certification. We remain the only
PV credentialing body in North America to have been accredited to this
standard.

I hope this helps. To each and every Wrench who is waiting for their exam
results-I hope you passed.

Regards,

Ezra

"Don't get me wrong: I love nuclear energy! It's just that I prefer fusion
to fission. And it just so happens that there's an enormous fusion reactor
safely banked a few million miles from us. It delivers more than we could
ever use in just about 8 minutes. And it's wireless!"
