I do belive in preparation only- you can not leave it to the chance!
I always teach my children the letters on the eye chart before they go to the optician's. You can't leave these things to chance, and I think they should do well in this important test.
Sorry, rarely am I this blunt: but please
This is a nonsense. Your poor child does not need to be familiarised with the test, it is self-defeating, it is basically a kind of IQ test, the rest of the country is sitting it with no preparation or familiarisation and your child is no different. I have never ever known CATs to be used for setting, streaming, culling or anything other than providing a bit of baseline data on a child. I doubt you can much change a score anyway, and if your child were to end up in 'the wrong set' it would soon become apparent. Please
