How long does it take to finish a course?
It takes approximately 15 hours to complete each Self-Paced Course, with the exception of Alexander Hamiltons America and The Era of Theodore Roosevelt, which take 8 hours to complete. This includes the time it takes to watch all video lectures and pedagogy sessions, and complete all course quizzes. However, there is no time limit for finishing a course.

What materials do I need to start a course?
Self-Paced Courses do not require purchase of any additional books or materials. All course quizzes are based entirely on the lectures, and the purchase of any supplementary materials is completely optional. 


Does the course have a time limit or expiration date?
There are no time limits, deadlines, or expiration dates for Self-Paced Courses. You can take as long as you need to complete a course—you can even begin a course, take a break, and finish it at a later date. Course materials will also be available indefinitely, even after the course is completed.

How do I obtain my certificate of completion?

After finishing your course by scoring 80% or higher on each quiz, you will find a “Click here to download your certificate” link under the last quiz.

This generalized certificate lists your name, course title, and number of credit hours earned. If the name on your certificate is wrong, or if you require more detailed documentation, please email

How can I obtain professional development credit hours for completing a course?
Each Self-Paced Course is equivalent to 15 contact hours of professional development credit (except Alexander Hamiltons America and The Era of Theodore Roosevelt, which include 8 contact hours). Most teachers are able to use either the certificate of completion or a more detailed letter of completion (obtained by emailing us) to receive credit for the course. If you are a teacher in New York, Massachusetts, or Texas, please email to obtain a letter of completion with our state PD registry number and the required course information, which will ensure you receive professional development credit. 


Can I earn graduate credit for Self-Paced Courses?
We do not offer graduate credit for Self-Paced Courses, although you may be able to get profession development credit (see question above).
