It does depend, first, on what tests are accepted by your school system.
The NNAT-2 is entirely nonverbal, and would likely be advantageous for your child, as it is pretty much all logic and patterns. Aspects of the WISC-V could be good, as there is a Nonverbal Index, which leaves off the VCI subtests, but not every school system will accept that as the global measure of intelligence. Other nonverbal measures include the TONI-4, CTONI-2, UNIT-2, and the WNV (Wechsler Nonverbal, which is basically several of the low-verbal subtests that have been part of the WISC or WAIS in the past, re-packaged).
The NNAT, TONI, and CTONI are basically the same idea, using some variation of matrix reasoning (abstract-figural patterning).
The UNIT and WNV are similar to each other in including measures of reasoning, working memory, and processing speed (so more areas than the first set of tests).
