KS2 SATs and secondary school

Theyre used to set target grades, but that's it. And thats only because secondaries have to report on progress from y6. Even as a target grade it isnt expected that all children would get that targey statistically (but some schools dont get that). Some will get above, others below.

And to be honest, my personal take is that they arent that good a benchmark. Its also why a lot kf secondaries do our own testing (&usually find the kids are lower).

I've got students who are working 2 grades abive target. I've also got students who are struggling to reach their gcse target because the primaries were so set on getting lots of kids to level5 (expected for y6 was a level 4) that they did nothing but maths and english for months. The kids got a level 5 and now are finding their gcse targets horrifically difficult because they were never really able to do the level 5 work well to start with. Just drilled on how to answer a paper.

They matter most to primary schools. It's how the schools are measured-rightly or wrongly.

Some secondary schools use them to set, some don't. Some use primary schools' predictions/Teacher assessment.

Do they set from September?
Do they do CATs on moving on days?

Personally, I think your child should care about them but not worry about them. A little bit of revision is good study practice, too much creates stress.

Whatever your child's ability, there is a balance- if they're not academic, keep focusing on their true strengths.
