In a few months' time, children in Y2 and Y6 will be readying for their SATS. My son had his Y2 SATS last year and my daughter had her Y6 SATS two years ago.
It amazes me when I read about how stressed and worried both children and parents are about the tests. In our area, many schools have parents meeting just to discuss it. But in our school, it's very relax. All we get is a notice in the newsletter informing parents when is SATS week. The kids aren't too bothered, although they get some fun time before they start in the morning. Then they have a party at the end. As parents, we only really helped by making sure the kids go to bed early every night.
The school's result is always above average, so I think the approach must work.
