One of the most profoundly gt kids we know didn't read early but when he "learned" he jumped 8-9 graded reading levels in the year. Everyone has there favorites but I'd go for a quickie WISC and WJ with the follow-up being a conversation about the results and general counseling. plus if you 'need' the testing to help with counseling your insurance may help defer the cost.
