My daughter is moving into year 9 secondary school. She is currently at a very big busy inner London comprehensive school. She is doing ok academically but not as well as she could. She is mixing with a group of students who are constantly in trouble and her behaviour fell off a cliff about 6 months ago both at home and at school. We agreed to look into her moving schools and she has a place for Sept at a local very small and nurturing private school. However her behaviour has improved quite a lot and she is now saying that she wants to stay at her original school. I have mixed feelings about moving her but on balance I am concerned that the day to day experience at her secondary school is quite traumatizing and that she is being very influenced (not bullied exactly but I think she is sometimes manipulated by her friends). Am I being unreasonable to insist that she moves?
