Project TND includes 12 classroom-based sessions. Each session is 40 to 50 minutes in length. Each session includes a review of the previous session, a primary activity, and a review of the activity. The method utilized for reviews and summaries is the TND Game, in which teams of students compete for points by answering questions about the curriculum material.

Overall, the sessions are highly interactive, with the use of the Socratic method, classroom discussions, skill demonstrations, role-playing, and psychodrama techniques throughout the curriculum.
