DS had an assessment to a prep school which is quite highly thought of and has good results. He is on a waiting list but the wording in the letter suggests that there is every possibility that he will get in. I haven't been through the British education system so it's all very confusing. If a firm place offer means "your child is going to fit in" then what a waiting list offer is. If they don't think he will cope at this stage than I'd rather he went to a less academic school for which he has a firm offer. It looked like they were thorough and I suppose that after all those years they will spot the "right for them children" straightaway. Would you wait it out or trust the school's judgement?
