From what I understand IQ testing at age 4 is pretty unreliable to begin with... not even fluently speaking the language the test is given in would make the whole thing pointless, I'd think.

There are tests that are meant to be better for children who do not speak English as their primary language.. the NNAT, for one. It's not nearly as thorough as most other tests.. it's pretty much just a non-verbal test.
