@MrsHGWells my knowledge is fairly sketchy (I will tell you everything I know so some of it will be useless information!) but from what I’ve been told/researched the Cat 4 and pretend SATs together generated a target grade. The school said in the talk these were ‘ambitious’ but as they were a great school where pupils did very well that this was very achievable and was in line with how other students with that score in the school did historically. It is also calculated from a huge cohort that take the tests country wide (think the tests were by GL assessment)
After they had taken them we got a huge report with their grades, what it meant, what we could do to encourage them in specific areas etc…
I know a friend’s child that got 130,112,118,131 in the CAT4 was predicted 8’s with a 9 for English (their 130s were verbal/spatial)
Mine got 140 average so are predicted all 9s which is a bit of a curse… but they are meeting that challenge so far in most things. And for them it’s been very positive as it encourages them to really push themselves.
I kind of understand how they can extrapolate things like maths/science from these scores but how on earth does it tell you if you will be good at art or Drama or music? So I think they do need to be taken with a pinch of salt.
There is some information on how they work out target grades on the GL website and it does vaguely make sense.
School also said that target grades were just targets and they regularly had children exceed them so not to be at all discouraged if they were lower than expected. In the end it’s a snapshot of how a child performed on one day so I don’t think it can be taken too seriously. Particularly in yr 7-9 hopefully that with 3 yrs worth of school performance together can give a much more accurate picture going into GCSE’s
I think what it is particularly helpful for is identifying children that are very bright but underperforming or ones with a very spiky profile, as they will learn differently.
