Carrying on from:
As a maths teacher the 7b looks over optimistic! I
can't believe the topics for level 6 and level 7 have all been covered
in one year!!! QCA optional tests put a 6a ceiling on Y7 levels
I still doubt a 7b ... the level is dubious!
Well, the 7bs in maths were probably achieved in schools that do a condensed KS3 in maths.
My son's school also do the KS3 in 2 years, and the first cohort that took their maths SATs in year 8 was last year cohort.
The results were similar to what year 9 students would normally obtain and a significant number of pupils got a level 8.
It doesn't seem unreasonable to believe that these pupils were at level 7 in year 7.
