comparison of these two areas. The link to dyslexia is in that comparison,
because the outcome would show that the child has average or above
underlying ability, but weaknesses in specific skills. It is this "mismatch"
that you look for in specific learning difficulties.
In my experience it takes about 2 or 3 sessions to administer with a KS2
pupil and is a bit fiddly with all the little cards, but does give a nice
clear picture. I also find it useful as a basis for discussion with parents.
My Ed Psych has been rather scathing about some of our colleagues who have
drawn simplistic conclusions about children's ability from the tests in the
Aston, so I tend to use it as a starting point rather than treating the
outcomes as definitive. The Ravens matrices, for example, might be a next
stage in pursuing an indication from the Aston that a child is of low
underlying ability.
I'm afraid I don't know "Chall" but I look forward to being enlightened by
forum colleagues!
