And I disagree with you. A child should not be deciding/changing schools in the middle of high school. As you well know kids have enough issues already to deal with! Changing schools due to moving, financial, yada, you get the point...is acceptable. This is where some questions come up about recruiting etc at this time. You allow kids to do that all the time and it would be a fiasco.
I don't disagree that a child should be able to go to a school that is best for them. But I think that choice should be made before high school starts.
