I agree with Angiepoise. It would be incredibly naive to say that every school was for every family. The Laurels walks the talk regarding values, and consequently it's pretty strict. That suits my daughter really well, but it's not for everyone.
But don't confuse upholding strong values with brainwashing or bigotry. My daughter questions everything. All the time. And I do mean all the time. I think that we can only understand who we are through that process of questioning. I'll give you an example, because the parents have used lots of superlatives and given relatively little substance. Once a week during philosophy, all the girls write questions, e.g. what is time, if good comes from bad, does that justify the bad, is a bad act justified by a good intention? The girls vote on a question and discuss it. The teacher only intervenes to bring them back on topic, not to influence the discussion. The girls are actively encouraged to develop their thoughts and justify them.
But I'm equally glad that there are clear rules for how the girls treat each other, the teachers and the school property. These girls also listen to pop music and go to Costa's after school on Fridays (other coffee shops are available).
As Angiepoise says, sending your daughter to a new school is a leap of faith. For that reason, we are invested in its success and probably share many values. But that doesn't make us robotic or cliquey. The school isn't perfect, but I've never once regretted sending my daughter there.
