Hopefully someone can offer a more CCAT specific piece of counsel, but this is what I was able to find in a short search:
- The CCAT, from my reading, closely resembles the COGAT. (Please see CCAT sections, see pp. 3,
http://www.assess.nelson.com/documents/CV-02-10.pdf)
- There is a predicted 90-97% correlation between the COGAT form 6 and WISC III for grade 6 results. (see pp. 12,
https://faculty.education.uiowa.edu/docs/dlohman/CogAT-WISC_final_2col2r.pdf)
A few caveats:
1. Assumes CCAT ~ COGAT
2. Assumes grade 6 and SK tests have similar g correlation across tests
3. Old test versions' correlations may be outdated
