I think the important thing to remember is that contingency based responses (if you do this, then...) are not the most effective and that problem solving is more helpful. The "old" structures of a "policy" are what is not working.
We are working with a high school that maintains their old reporting procedures, but when students reach a certain number of tardies or truancies, they meet in a group during lunch to talk and problem solve. Listening to the students is powerful.
Learnings: Part of the problem is that the academics are not relevant. Part of the problem is that there is an open campus and lots of students leave for lunch and can't make it back in time (most recent proposed solution is a food truck across the street - which hasn't yet been implemented).
What happens if we work with students and make them part of the solution?
