A little while ago there was an article in the local paper about primary schools and how they rated, this wasn't based on OFSTED but took into account a wide range of issues and came back with a score that then ranked the schools. I remember reading the same last year.
For the last 2 years, my DCs primary school has had NO SATs results that were above expected. So not a single child in year 6 in 2 years achieved above the expected level. That seems surprising to me. The Year 6 teacher is also a fantastic teacher, but not competitive in any way so wouldn't be interested in pushing any children 'up,' in fact the school in general has an air of 'as long as everyone is in the middle then that's good.'
DS is having 11+ tutoring, and he really enjoys it. It's because he is being challenged and school doesn't challenge him as it's all about middle attainment. His Year 5 teacher told me that's why he would enjoy it, and its true. DS and a small group have always been a group at the top of the class so I stuggle to see how they are the ones that are at expected levels, not exceeding. DS is feeling very fed and frustrated at school at the moment.
