Hard to say. Will your school accept any test? There is also K-ABC, WIAT, Woodcock Johnson (which is nit an IQ test but is achievement testing). Our school did not accept my son's RIAS score of 160 (but MENSA did) for our GATE program , but did accept his 99.1% on the Raven's test. So it can be a good idea to check what they will accept before you spend alot of money.
