Do I have to take both the Intro and Advanced modules?

No. You may take the Intro to Kids Yoga alone if desired. If you are seeking RCYT status, you must also complete the Advanced Training: Kids Adaptive and Accessible Yoga (KAY) within a 3 year period, but you are welcome to take only the Intro to Kids Yoga. You don’t have to decide up front; take the Intro class and see if you want to continue with the KAY module.
