I can see that logic is not going to get me anywhere!

What I'm trying to do is to use the SCAT scores as a proxy for other achievement tests so that I know whether to encourage friends to pursue further testing in the hopes of getting into DYS. Perhpaps that's asking too much from a 44 minute test!

Do SCAT scores tend to correlate reasonably well with SAT or WJ-III or WIAT? Or is it too limited a test for that?
