Alright I'm not a teacher-I'm a parent. I can sympathize with you. My daughter's been at the same school for 5 years and she takes 3 classes with 6 different teachers. My daughter competes in solos in Irish dance.
I have seen it all too. Here's what I have learned:
1. We are NEVER late to class but I've seen some late every
class-and the class was at 9am on Sat 1st one of the day--if
you can't get your and your daughters butts out of bed don't
take that class. One time this past year we were late to class
but it was because we had to go between 2 studios and the 1st
teacher kept them late. The teacher of the 2nd class told the
girls when they went in "you're late". Nobody is late to this
teachers class. The other teachers make no comments about the late ones.

2. I am tired of the mothers who are at the teacher everyweek
after class. How could you possibly have that many questions?
I rerely ask the teachers questions but when I do they are
very importent. I think the teachers must cringe when they see
this mom coming over again. Kissing up to the teacher does not
help your daughter. I would think it could hurt her.

3. The dancers are expected to practice at least an hour a day
at home every day. Some don't and that sets back the whole
class. I've never seen the teachers say anything to them but I
hear they do. I heard one of the teachers told one of the
dancers if she couldn't practice perhaps it was time for a new
hobby.

4. Most dancers wear the proper practice attire with hair back
because if they don't they will be spoken to.

5. I have heard one mom complain about the teachers, steps,
school-she doesn't think one of her daughters is learning fast
enough. Well the teachers have bent over backwards for her
(extra lessons for the daughter, ect) (she's also the one who
is constantly asking questions)If you don't like something or
don't think your daughter's being taught leave.

In general I think I'm a good dancers mom at least I try. My hats off to my daughters teachers and all you teachers for putting up with all of the stuff we parents do.
