I am in d54 as well.
We have a few friends with kids in the magnet program. It is very challenging. The district will not accept any outside testing. I don't believe you can appeal either. Your daughter can not be retested for another year per WISC testing guidelines.

Here is a link to the district's gifted website:

The district also does not believe in acceleration other then the accelerated math program which starts in 3rd grade.
