....maybe the easiest solution to this would be to allow more control over the time frame that the minutes are to be met in, i.e. semester, quarter, month, 3 weeks, etc) and then for the remaining minutes that need to be met during the 4th week one could manually schedule those in. Just a thought....

Was going to say the same thing! This would be extremely helpful if you could just set up availability restrictions for each teacher since so many of my kids are from the same class. It would be great to just click "Mrs. Smith's Restrictions" (such as their music, recess, lunch, library and computer time) for each student and then add any additional restrictions that each student from that class might have.
