DD5 missed the Sept 1 deadline (November birthday) for kindergarten entry so we had her tested for possible early kindergarten entry through The Center for Gifted in Glenview. They are affiliated with NIU, I think. The psychologist was Cheryl Lind and she did the WPPSI-3 for IQ and WIAT-2 for word reading and math for like $275. I don't know what she charges for other tests but I thought that I'd toss this out there for whatever it's worth...
