Moving your 11 year old daughter (I should think she is 11 as prep school is 8-13 and she has been there 3 years) should not be a problem especially as you are a teacher. I am a teacher and my kids were lucky to get assisted places at private schools (most of their junior school pals went to private schools at 11 anyway). However,in my state school workplace I had no end of criticism about disloyalty etc and one of my teacher friends outside of school kept on about t as well. So you may be saving yourself a whole world of inverted , right-on lefty snobbery by putting the girl into a state school. Word of warning though..state schools, despite their protestations to the contrary, are absolutely shyte at dealing with bullying....both pupil on pupil, and bullying of management on staff is positively encouraged!
