Does anyone have experience with the Reynolds Intellectual Assessment Scales (RIAS)? It's one of two tests (along with the CoGAT) that our school administers for placement in the GT program. My 6 yr old scored at 99.83% on the RIAS and in the 80% range on the CoGAT. The discrepancy struck the GT teacher and counselor and I'm curious about the differences between these tests and how to interpret the disparate scores. Thanks!
