Quizzes contain multiple-choice questions with one possible correct answer. A small percentage of the questions may be true/false.

Quizzes are not timed. After purchasing the course, you can view and print the quiz; and you can take as long as you like to complete it.

The length of the quiz varies according to the course length. A 1-PDH course contains at least 10 quiz questions. Longer courses typically have 5 questions per PDH of course content. The number of questions for each quiz is specified on the course overview page for the course. Quizzes are made up of multiple-choice and true/false questions.

You have two years from the date of course purchase to take and pass the quiz for PDH credits. Courses not completed within that time frame are ineligible for credit. PDH credit is not awarded for courses until the quiz has been passed.
