Since this program is self-paced, that’s really up to you. We designed the program so that each unit could be reasonably completed in about three months if students put 5-10 hours per week into it. If you follow that schedule, it would take four years to complete all 16 units. However, it is possible to complete units as fast as one per month, which would move you through the program in 16-ish months. And of course, there are students who choose to take longer than three months per unit, which is their prerogative.  In other words, you do you, boo. When you’re on the path to learning how to become a pet behavior consultant, there’s no need to rush!
