Are your dc teacher assessment grades level 6 or above?
If you pass the level 6 paper then does that equal a ks3 level 6 or is like like primary and a level 3 on ks1 sats being easier to get than a level 3 on y3 optional sats where you need to know more.
My ds is teacher assessed at 5a and in mock tests has been "passing level 6 papers with flying colours". If this turns out to be true does that mean he's been taught to the test well (he started learning level 6 work after October half term) or could he be a level 6 at maths? (he is the one who wants to know the latter)
Friend in the playground with similar ability child says that maybe they are not confident assessing level 6+ in primary so give a 5a and leave it to secondary to assess level 6 and sub level (this is a new school and second year that anyone has graduated)
