The passing score required by most certifying bodies is either 70 or 80%; therefore we have elected to go with the most rigorous requirement of 80% for our courses. However you may study and take the quiz for any course as many times as necessary to master the content and achieve the passing score, after which you can download and print your certificate.
As a general guideline, most accrediting bodies require 5 knowledge review quiz questions per instructional hour. Since most of our courses are 4 hours in length, 20 questions are typically required. You may however take the exam as many times as needed to achieve a passing score of 80% during the 30 day course completion window.
