Pink,
Does your DD like tests? If so, perhaps request the K-BIT and Slosson anyway. There is a chance that even if the bar is 'rediculously high' that she would pass it with ease.

I also like the idea of private assesment. This year's teacher sounds like a gem, but I wonder if subject acceleration or a grade skip will be part of the solution for your daughter. You could try to formally apply for the full grade skip for next year as a way to rush the individualized testing. In the end, no matter what the test says, "Gifted is as Gifted does." IF you daughter is doing the advanced work, that is reason enough.

Best Wishes,
Grinity
