Yeah, I don't see how skipping to 1st grade helps a kid whose lowest level of achievement is 5th. And skipping to 5th probably would be a non-starter, not only because of the usual prejudices and the extremity of the skip, but also because she'd have missed a huge swath of social studies and science exposure.

I honestly don't see any institution having anything to offer her, though there may be places I'm not aware of that can. Homeschooling, on the other hand...
