Just because your child is the one going to BS and not you does not mean that the fit doesn’t need to be right for the parents too. If you disagree with the school’s policies or major parts of its philosophy, it’s going to be tough on everyone. It’s likely that at some point in the 4 year period, something will happen that bumps you up against these. Since you’re co-parenting with the school in many ways, it’ll be much easier to work through these issues if you feel comfortable with their overall approach.
