This is a work situation, so I put it here, but it does deal with families and children.
I have taught piano lessons after school at a private school for three years now. I have taught out of my home, and years ago in another city.
My school provides a co-curricular policy that outlines how parents pre-pay each semester, that lessons are 30 minutes, make-ups are only at the teacher's discretion if a student misses, there are Christmas and spring recitals that you are expected, but not required, to attend, and that materials are different for each instrument and teacher so you will need to buy certain books, metronome, etc... at the teacher's suggestion. Pretty standard information, but general enough because we have teachers for brass, woodwind, piano, dance, study skills, photography, etc...yet only use one small handbook for all.
The policy book does not say that you have to have the instrument that you are paying for your child to take lessons. It does say you need to have the right supplies.
Note- none of these students exhibit a financial hardship. We are two weeks into school and lessons are pre-paid and optional.
So, my question is, as you can surmise from the poll, how would I address a parent that assumes the Santa Claus option?
