The true question here is what kind of TEACHER is she...has she had good or excellent evaluations?
What goes on in her home doesn't mean anything like that will ever happen in the classroom.
If the school feels comfortable in hiring her and letting her teach then her problems have probably been addressed and are under control. After all it was 11 years ago. She made a mistake and paid her dues to society and sought help.
I taught for many years while dealing with an anxiety issue, the teacher down the hall dealt with manic depression, down the other hallway there was a teacher who was an alcoholic, upstairs there was a teacher who dealt with bipolar. Were we good teachers, yes we were...we got excellent reviews, we did our jobs above and beyond, and one of us was Teacher of the Year for our whole district. We loved our students and never let our issues into the classroom.
Wait and see if your child even get this teacher...only a 25% chance that they will...and go from there. If you can't stand her once you meet her then go and have your child changed.
But PLEASE do not drag this up to all the other parents and ruin her career over an 11 year old incident.
