How important is reading age assessment in primary school? I was told at parents evening last year that my 7yr old DD had a reading age of 10yrs. A year has now gone by and I asked at a parents evening last week if a further assessment on reading age had been done and was told yes and that my DD now had a reading age of 8yrs! When I questioned why her reading age had fallen from 10yrs to 8yrs over a 12 month period I was told she maybe had a bad day and reading age isn't important!
