It doesn't sound like you are on the verge of making the jump to the K-12 private prep school, but I would advise some caution before you do so. You would think that would be a good environment for acceleration, but in our case it has actually been terrible. What seems like such a good idea and simple to execute has been blocked at every turn by the administration in our case. I have had to be a complete Tiger Mom to get the tiniest accomodations... Of course, your private option may be totally different. But don't just take the admissions people's word for it if you look into a change -- talk to parents of kids who have been allowed to accelerate. If they can't produce 'em to talk to, then they don't have the goods. So... the grass seems greener in the K-12 private world, but it may not be.
