Have cantacted Senco at her current school but they are not supportive of the Grammar so not bothered. Have also spoken to admissions at the Grammar but they were not sure how they could help either. Arrgh!! Think it may be a case of 2 different pairs of glasses for the two different tests.
Just some thoughts - can your DD show her true NVR potential with alternative glasses, if so that is the solution. Can she happily switch between glasses without a period of adjustment. Might be an argument to take separate tests on different days.
Don't speak to people, email, get it in writing, just in case.
Getting adjustments seems to be a catch 22 situation, fair enough if it stops abuse, you have to ask for adjustment and then demonstrate that the existing school provide it with supporting expert medical documentation. Unlikely as the primary school probably don't major on NVR.
