Low A level assessed grade from teacher who doesn't like DS - WWYD?

[Wonderwine]

DS has always had a problem with one of his A level teachers who doesn't seem to like him (a vibe we picked up early on at parents' evening).
Some of it is of his own making, as in Year 12 he was a bit disorganised/lazy and didn't do very well in his mocks. However he admitted this and has pulled his finger out and worked hard this year.

We had a bit of an issue with this teacher when A level grades were being predicted as he predicted a B for DS on the basis of his mock exam, whereas all his other work pointed to an A being appropriate. In the end we challenged it with the school as it was important for his UCAS application and the teacher reluctantly changed it. However he said that he 'saw DS as more of a 'B' sort of person' and that DS would need to do something very 'different' to change that .

Anyway, DS has worked hard this year, but still feel this teacher dislikes him (and us) for challenging the prediction.
As part of his A level he had a piece of internally assessed work
(20%) which this teacher has given a 'B' equivalent mark. It is a small class and DS knows it is the lowest mark. Knowing the usual quality of the work of some of his peers, he feels that he has been unfairly marked harshly.

What if anything can he do? The teacher is also the head of dept, so there is no higher teacher to appeal to.
I don't know if all the projects get moderated by the board, or just a sample of them.

DS has been told he can appeal to this teacher, but he has no information about why he has been given the mark he has, so doesn't know on what basis he would appeal?

I don't think its to do with predicted grades at the moment, because we have had access to UMS data to attempt to correct for the bias. When we don't have that anymore it is going to be harder.

Regarding your post, mitigating for bias isn't the same as the bias not existing. I;'m glad your school is all over the mitigating - that is certainly a good thing. I still think you are all biased...unless you are not in fact human...

The LARGER problem is the bias in teaching that goes on. When girls are systematically underestimated in STEM and not encouraged as much as boys to take triple science GCSE, or A-level maths. further maths, physics, chemistry...or to go back to the real route of the problem...taught to play with dolls not trains in nursery.

There was someone on here recently who had complained to their child's nursery because only the girls were encouraged to help with tidy up time at the end of the day.

If I could wave a magic wand and fix this problem I would start with childrens books, TV and most importantly advertising. No more 'get the power' adverts that only show boys, no more 'everyone wants to look their best for the ball' adverts that only show girls.

The next thing would be unconscious bias training for all nursery and primary school teachers. No more girls do tidy up, no more 'sweetheart' 'hero' endearment biases. No more rating girls 10% less good at maths than the boys who scored the same on the test.

THEN people working in Secondary education might have a fighting chance.
