118 is a respectable, borderline score. It would be helpful to know whether this was for the first or second test, and what the other score was.
118 was the first score, 111 the second (I know it's a strike against him)
You do have mitigating circumstances - it can't have been easy for your son transferring to another country, a different curriculum, and a different year group. Could you confirm that the headteacher's "1" was for academic potential, and the "2" for attitude? If so, this could be more useful than evidence from a foreign school.
The 1,2 was as you stated.
The panel would probably expect to see a report from the school in the US, but I doubt that it will help very much unless it clearly states that your son is well above average ability, and you can prove that this was a high achieving school.
The school reports do state exactly that....I'm not sure how to prove the schooling was high achieving would a letter from the principal work? I can pull reports off the schools website that says they achieve a 90% pass rating on their standardized testing (KS1 type testing) and the state average is 60% is that enough? I don't want to overwhelm them with papers, but I can prove all of this. I also have his test scores from the cognitive ability testing he took to get into the advanced cirrculum in the US.
Also would letters from his teacher and pricipal in the US be helpful?
If you have time to spare, you could get hold of some VR tests from this website or a bookshop like W H Smith, and research whether you can find examples of any questions that would be problematic because of differences between British and American English. To be able to show a panel some real examples (albeit from a different test) would help make your argument more striking.
I do have one of those, probably need a few more though?
As stated in B19, time and money permitting, a report from a qualified educational psychologist (using WISC or BAS tests) could provide useful additional evidence of cognitive ability, especially if the outcome is very favourable (e.g. results at the 90th+ percentile).
Where might I get a hold of one of these psychologists?
THANK YOU so much for your help.
