Those of us that have been in nuclear power since the 1980's (or earlier) recall it as being the "Northeast Utilities Exam", which was administered by Northeast Utilities (previous owners of Millstone Nuclear Station) to contract HP technicians, to assess the technicians' knowledge of basic health physics.
When Northeast Utilities went defunct, the control and security of the examination bank became questionable. INPO (specifically, the National Academy for Nuclear Training) eventually assumed control of the examination bank, and the NUE (Northeast Utilities Exam) has been re-born as the NANTeL RP Fundamentals Exam. The NANTeL website (https:\\www.nantel.org) has both the courses to prepare for the exam, and the exam itself. One has to be registered as a student on NANTeL, and then be proctored for the examination.
Here at VC Summer, we've replaced administering our own in-house HP Fundamentals Exam with the NANTeL RP Fundamentals Exam.
From what I've been told, the NANTeL RP Fundamentals Exam, and/or NRRPT certification, is the direction the industry is taking as a whole, to assess and validate the technical knowledge of their contract HP personnel. I would encourage anyone who has neither NRRPT certification, or has not taken the NANTeL RP Fundamentals Exam, to begin studying in preparation for either exam. It's what will be expected in the near future.
