I need some advice. I started teaching in Year 6 this year. Historically my school has been plagued with rumours that the senior management team, when acting as readers in finals SATs, blatantly point out incorrect answers or tell children how to work out maths problems. They don't go as far as telling the children the answers, but it is not far off. This week we've been doing optional SATs and I have observed all of these things happening. It makes me sick to my stomach. I've seen the deputy head explain which operation should be used when solving maths problems and telling children when they've got questions right or wrong, and the assistant head pointing out the correct answer in reading tests. My less able maths children did their SAT in a room with our headteacher, and happily reported the help he gave, rephrasing questions and explaining methods. I know this is only the optional SATs but it does appear to confirm all the rumours I've heard in the past. These practices go against everything I believe in. I am stressed to bits about this. I want to speak to the head about it, but it is an incredibly prickly situation and our head is not the most approachable of people, and can be a bit of a bully. What should I do?
