Hi, I've been getting 'good' or 'good with outstanding features' since I began teaching, including a 'good' last year by OFSTED. For the past few months, I 've had a new mentor, and she has given me satisfactory lessons for the past 3 observations. Last week I was observed and got a another grade 3. The thing is, the behaviour of the pupils was fine, pupils produced good quality work, there was a good pace, good subject knowledge, good level of questioning, and she even said the first half of the lesson was 'outstanding', But she said that the work was a little too challenging for Level 7 students. That was the only criticism. I also feel that it's one of the best lessons I've ever taught, much better than last year's 'good' by OFSTED. Should I voice my opinions? Or contact the union? Or am I stressing about nothing???
