Well, the website lists 3 different individual tests, so any of those. I do think it is much better to go that way. WIAT and WJ are very widely used. Psychologists and educational consultants should be able to apply them. While I worry about IQ testing and the tester (usually much better to have someone familiar with gifted children); I don't have that same sensation regarding AT.
Our DD took the WJ and it gave us a lot of extra information. I am glad we went ahead with it.
Are you in public school? Maybe you can ask around, counselors might be able to steer you in the right direction, Hoagies list might be useful.
