I am pretty sure we will be getting her retested on the SB-V by someone who sees more than the occasional gifted child. Particularly if school are still not inclined to co-operate.
I agree Mum that your DD is too advanced to be properly tested on the WPPSI, and that the scores is likely to be an underestimate - but - the scores she has are certainly gifted. Locally to me, the schools don't even care that a scores is over the 130 mark, let alone neighboring 140. So I wanted to check, do you have clear indications from the school that they will provide accommodations to 150 that they would deny to 138?
(A few schools do have a 'Highly Gifted' program with a higher cut off than 130, but, locally, those school do the testing themselves.)
I want to be sure that you aren't 'just assuming' that schools even know how to interpret IQ scores - or are impressed by them.
Our school said: We don't care about IQ and Achievement tests because they don't take into account how far 'above average' our students and teachers are.
Of course they we also in 'say anything' mode at the time.
Love and More Love,
