The Video Class Subscription and the Online Teacher Certification Program are absolutely complimentary! We recommend having well-rounded experience with many different types of our courses for your personal practice hours, which is a Teacher Certification Program requirement. That said, you cannot use the VCS for personal practice hours, and you can get everything you need for certification in the course itself.
The teaching certification goes deep into the understanding of both the philosophy and the practical elements of the Five Elements and Three Treasures philosophy, as well as movements and meditations and how to teach effective classes. Seeing it in action over time via the subscription is extremely helpful, as well as providing a wide variety of additional movements you can draw on as you deepen your practice and begin to teach.
