Last year, a new head-teacher at DD2's school happened at the same time as a fairly weak Y6 cohort, so the SATs results were not improved as the governors hoped they'd be (not that they'd been poor to start with).
The Head was blamed for this, so this year, the staff are going all out to improve the results, with head going in and taking the top tables for higher-level work, freeing up the other tables. It's been SATs SATs SATs all the way, and is quite frenzied.
The children were sent home for the holidays with 4 papers to do.
What has really annoyed DD2 is they teachers telling the pupils "You've GOT to do well with your SATs, because the schools you're moving to use them to decide which set you'll be in, so if you want to be in a high set, practice more". DD2 counters this by telling her friends that none of the local comps use the SATs to set children, and the grammars don't set for at least two years, if at all.
We did ask the question when going round the comps, and all told us that they didn't trust SATs as some primaries tutor more than others. They all run their own base-line tests to assess new pupils within the start of Y7 rather than using the SATs.
