I've taught for 20+ years and, about 10-12 years ago, I stopped doing this sort of thing. To be clear, I have behavior expectations and there are corrections for those who do not meet expectations, but a 1:1 list of rules & consequences adds another thing to the teaching load. If I put that sort of discipline/management plan in place, that means I now have to keep score of every time someone runs afoul of the rules and enforce the consequence to the letter. On top of teaching music, managing budgets, attending ARDs, inputting grades, doing T-TESS, and any other list of things, it becomes too much and there are some things that just can't be dropped from the "to do" list.

My philosophy is more about encouraging/empowering students to make good choices, hold each other accountable, and respect the program at the highest level. Each student is responsible for the overall discipline of the program and are dealt with individually when needed.

To your example, if a student misses an after school rehearsal, it's reflected in their grade and/or performance opportunity. If they miss a sectional, I'll allow them to attend a different sectional that is already on the schedule. If their absence was "with cause" and communicated in advance, they'll receive full credit. If not, they will receive a 70 for their attendance.
I *will not* require myself to be at the band hall so a student can "make up time" for a rehearsal that they chose to not attend. Once upon a time, I would schedule a "make-up" sectional, but those became more of a hodge-podge of students and weren't as productive as one might hope. It turned into a "scale jail" situation and that wasn't fun for anyone, including me!
