Hi Labmom, I think you have 2 options: 1) submit what you have with a portfolio; 2) have testing done to obtain composite scores.

I submitted scores for my 2 DYS (we've never tried the portfolio option, but plenty of others have - successfully). For DS, he had a WJ performed very young for a gifted program, with high subtest scores, but no composite. I opted to have him retested on the WIAT almost 2 years later, so we could get the required composites. The added benefit for us was a chance to allow him to demonstrate his newfound love of math.

Whatever you decide, best of luck to you and your DC!
