It's all relative though isn't it! A school where a majority of the staff are rated "outstanding" but which has one "good" teacher has, in effect a weaker teacher. Some teachers have definite strengths in a specific year group/key stage and may struggle outside this comfort zone, does that make them a weak teacher or a specialist? A teacher coming back from long term sick might need more support and would benefit from an "easier" class until they are up and running, does this make them weak? An NQT clearly has a great deal to learn in terms of classroom management/subject knowledge, ( no disrespect to NQT's, I was one myself!) and is thus a "weaker" teacher in terms of experience. I think we have also made the point that years3/4 were where <u>historically</u> weaker teachers were put but in the present climate there is no room for this!
