I don't know much about it, but I understand Carol Morgan is well regarded. Most of the people who go there seem to drive SUVs and be pretty well off. I have only talked to one person personally about it, and he was satisfied with it for his kids. The price was his main complaint as I recall. As a parent, you should personally check out the school you are using- that rule applies more here than just about anywhere. I was associated with an "English" school for a short time and the lack of educational standards were absolutely appalling not to mention the lack of discipline and lack of respect of the students as well as the poor classroom equipment. Shall I go on?
You should see the classrooms. If you don't know which classroom is your childs, can I kindly suggest that you aren't involved enough? You can check yourself to see if there is toilet paper in the bathrooms and blackboards on the walls, desks for the students and lecterns for the teachers(academy grades) etc. etc. You should pop in during school hours preferably unrecognized if possible. You can park outside and watch the students leaving after school or while they are playing outside. Are they orderly and happy and all of those other good things? Perhaps more important even than those things, is that you should have a warm relationship with the teacher-and not just at PTA meetings. Perhaps something more like a weekly or biweekly chat with the teacher would be more appropriate. Sorry if I am rambling, but it really hurts me to see parents sending their kids to school either assuming they are getting what they are needing or else not caring or perhaps seduced into it through a "friendship" with someone associated with the school when all the while, the kids are learning almost nothing except bad character traits and poor work habits.
