The plain report will do for the WISC, as long as it includes the VCI and/or GAI.

The WIAT scores are also qualifying.

DD9 got in with one qualifying score (Broad Math) on her Woodcock-Johnson - the others were all below the threshold, and they still accepted her without a portfolio. Her occupational therapist wrote her recommendation.

Just fill out the form and turn it in! The worst thing that could possibly happen is that they will ask you for more information. But I doubt that they will.
