From what I know of other schools in the area, it appears that the class sizes are too small at that school. Kids aren't challenged enough in small classes. The parents might think that their child is wonderful, if they are always scoring highly in a small class, but in actual fact it's hardly indicative of the real world. They aren't getting the chance to mix in a greater social setting. Larger class sizes provide the children with a greater range of partners, to do more effective pair and group work. It also gives them a chance to expand on their ideas, by cross referencing thoughts, and engaging in critical thinking practices with their peers.

Also, for what it is, it's far too expensive. It's an unknown quantity, and it's totally unproven in terms of test (GCSE and A level) results, and really that's what it boils down to at the end of the day. Why would a paying parent take the chance, when they can get the real thing with a proven school up the road for the same price? Or, even a lot less, at that school MIS that was mentioned. Perhaps if the owners weren’t so greedy, and were more realistic with their fees, things might change.
