Hey @countingdaysuntilretirement I agree with lots of posts on here but wanted to add my own PoV. Mainly tho, what is it that you are so worried about? Why do you think the tiering is unfair? You say it will limit her options, but it really will not. If she is looking at A level then she should be working at grade 6/7 anyway. If she just needs a pass in maths to move forward, the F tier is fine, if that is right for her.
Here’s the thing – F and H tiers are a good thing. The overlap is grades 4 and 5. If a student is a 5 at best, they should take F. It’s a lot easier and more accessible (my subject is MFL but it’s the same for maths and science) so they are actually more likely to feel confident which will boost their exam ability for sure (imagine an exam where you can only do a quarter of the questions).
If a student is a pretty solid grade 6 then they should do H. If they drop a grade then they will still get a 5. If they have a mare and drop two grades then they still get a 4. If a student is not likely to get a 4, in other words if they might do badly enough to get a grade 1 or 2, they should emphatically be doing the F paper if available (unfortunately on most exams it is not).
Teachers will know btw what grade a student is working at, even if the student is unsure.
If a student is a good 5/6 on their best day then IMHO it should be up to them. They should try past papers at both tiers (easy to do) and see what they think. Would they rather have an easier ride to a safe 5 (I have known plenty of pragmatic students take this option, esp in MFL, and why not?) or do they really have hopes of a 6 and want to take H? I’m for playing it safe tbh as I cannot see any massive benefit of a 6 over a 5. Grade 6 in maths and MFL (esp if a “maybe” 6) is not good enough for A level, and a grade 5 on your list of GCSEs (instead of a 6) is going to make zero difference going forward. Pretty much anyway – I know some unis ask for a 6 in maths as a general entry requirement, so I guess that’s worth considering.
And yy the GCSE certificate just states the grade, not which tier you took.
As others say, only maths, science and MFL exams are tiered; actually I think this is a massive issue for English (no tiers), where the paper is almost inaccessible for some weaker candidates, rather than the tiers in maths and MFL being an issue.
