New 1-9 GCSE grades and CAT stanines

[LanyardAhoy]

It has just occured to me - do you think the CAT test stanines were the inspiration for the 1-9 grading scheme for new GCSE's? The figures being banded about re the approx % of children expected to get each of the 1-9 grades seems very familiar to the distribution of scores using the stanines.

Can't believe I've only just thought of this!

you're just showing off with that big word I had to google

dunno, don't care! Don't even know what CAT scores DD got. Would rather she didn't have so much pressure, though, guess that's what comes with her actually caring. (Trying to look on bright side of having a feckless teen DS)

The only figures I've seen for % of students getting various grades is that the percentage getting 7+ is pegged to the % currently getting A/A* and the percentage getting 4+ is pegged to the % currently getting a C+.

What have you seen?

The reason that 9 is the highest and not 1 is so that they can eventually add even higher grades above it

Or so that the grades can be very easily summed into a total points score, then this could be used for league tables, e.g. % of students scoring 50+ points.

This briefly crossed my mind but the percentages for A/A* grades in different subjects are different, so I stopped thinking about it.
