Feedback helps to boost grades
The pupils not only get their grades, but an effort mark, comments on what they have done well and targets in areas where they need to improve.
Tamsin Trollope, 14, said: "Now we're in Year 9 the marking has got a bit tougher, with Sats coming up. Sometimes I don't put all my effort in and then my effort grade will be a 2, say, which means you're not working your best - and you know that is right.
"Effort grades go from 1 to 3 or 1 to 5 and they help because you know whether teachers think you need to put more effort in."
Brantley Rogers, 14, said: "I think the marking is generally fair. I've never complained about my marks and I don't think anyone in my class has either.
"Comments help you more than just a grade. If you have gone wrong but the teacher doesn't say why, you just keep getting a poor grade. But if they write to say 'improve on this' then you can get a better grade.
"In primary school they were not as full on about it. They looked at positive things but I didn't really get many targets. In secondary school we have a lot more targets and I think that helps."
