What is the passing score for the NBRC’s NPS exam?

I am going to be taking the Neonatal & Pediatric Specialty (NPS) exam for Respiratory Care. This exam is courtesy of the credentialing agency for the Respiratory Care profession, the National Board for Respiratory Care (NBRC)….The moral of the story: I don’t know what the passing score for this exam, and I’d be very appreciative of anyone who can give me the answer to my burning question. Thanx.
