DD1 did 16, Dd2 did 14 and ds did 12.
They did do them over 3 years, but most of the dc do at least 12 GCSEs or GCSE equivalent at their comprehensive.
Personally I don't like it; I think they'd be better to do well over 8-10, then stretch over so many, but whenever they've held consultations, the parents on the whole support it.
Op, you are right, and wrong. If that makes sense.
I do feel it's unfair. It costs around about £50 per paper. That's per paper, not per subject; most subjects have 2-3 papers. If we'd had to put everyone of dd1's papers back in for a remark, we could have at a stretch risked losing around £1000. Other people would be in the position of not being able to pay the £50 up front for one paper, even with the likelihood of getting it back.
The dc's school has a fund for people whose teachers consider it worth challenging, so that anyone can apply for that fund, and some the teachers will approach the pupil and offer.
With the ability to get the papers to view this means they can target papers that they can see issues on.
But that's also why they changed the "remark" to "review". Because in some subjects that was giving two bites of the cherry - hoping that if examiner 1 didn't like the answer, examiner 2 would and give them 2 more marks.
Now examiner 2 would look at the question, think, well I'd have given 2 more marks, but that is within tolerance so they don't get more.
I have two thoughts on that; firstly I'm not sure that's fair because a different examiner would have made two marks more, should they get the marks? But then I think of the advantage of being able to pop your paper through again and hope that a different examiner thinks slightly differently then gives a huge advantage to the wealthy.
For example, dd1 had one (history I think) paper she was a bit disappointed in her mark. She was 5 marks off the next grade. She got the paper back to see with her teacher. The teacher said that they felt that the marks were harsh but within tolerance. With a different examiner, the teacher reckoned there were 8-10 points that could have gone either way; with her examiner every one was a "no".
Is that fair? On the face of it, no.
But let's get down to the reality:
Different examiners will mark differently, especially in the humanities/arts due to personal preference etc. When your papers go off you have an equal chance of getting an examiner who likes your style/dislikes your style as everyone else. Let's say it's 50/50.
So you have a 50% chance of getting an examiner who likes your style.
If you are allowed to put it back in for a second go at getting an examiner who like's your style, it's 75%.
So unless every paper is put back in for a second go it is hugely advantaging those who can afford/have the knowledge/have supportive parents to be able to put it back in.
I wouldn't want reviews of papers to be taken away entirely because there are those where mistakes are clearly made - a question isn't marked etc. But I don't think putting it back in "because it's close" is fair. If you asked teachers to make a case, then I suspect the reviews at comprehensives would drop next to private and grammar.
So I think the review is as fair as they can make it.
