The Threes Training Course Extension will allow you uninterrupted access to the YTT course content through Sunday August 24, 2025. You will also have the opportunity to schedule two 15-minute office hours with a member of the Education Team between June 1 and August 22. Upon successful completion of all coursework and the final unit by the extension deadline, you will receive your Threes certification! There is a registration fee of $500, and this for a one-time extension.
