I will have 14 students, and two of them will come every other week. Two others, who are taking lessons on an evening that I have a school meeting once a month, will miss that one week each month. It's not ideal, but it happened this past year with my Monday students, and it actually worked out better than any of us thought. Both sets of parents told me that they liked having the break once a month, and since we all knew the schedule ahead of time, I was able to assign the kids a little extra work when they had two weeks between lessons.
Monday: C&S, K&D, K&K (every other week)
Tuesday: R, Z&J
Weds: J,J,&D
Thurs: R&M
I stress out about stuff like this every year, and every year it works out. Why do I stress?!?! In other news, I printed out membership applications for two music associations, one local and one national. If I have this active a studio and plan to continue it, then I should join some professional organizations. So that is something different for me.
