Potatoes I'm getting the impression that you think the NT way is the correct way and therefore if people with ASDs are marked down because they process information differently, that's okay?
No and yes.
I've learnt infinitely more about ASD from this thread than I knew previously and assuming people with ASD are more literal thinkers (usually the case?), they're going to do better in tests where literal thinking is absolutely necessary. The point of these exams is less to see what a person knows as it would be for something like a job interview and more to see what they don't know. If a teacher can look through the test and say, "ah, FutureJunior was great at x,y,z questions about modals. Oh, he got 5b. wrong. I'll concentrate on that with them next week."
Using the tests as a tool to see where students are wrong means the teacher can adapt and teach them. Getting a question wrong gives the teacher useful information. If they see that the issue is simply that they were looking too literally then they can use all sort of methods, examples and practice to show the differences.
In this case they were processing the information wrongly. It's okay to mark them down because the teacher can focus on how to change that in the future. If the result is simply a differentiated lesson plan or particular changes to the way it's all explained to the child then how is it a bad thing? If the teacher and school are good at their jobs then by the time it matters (GCSE, IB etc) the child will hopefully adapt their thinking and answer correctly.
Whether examinations are the correct way of a teacher assessing pupils is for another thread where I suspect we'd actually agree

That's a bit close to "The NT way is better than the way people with ASDs process things"
Not better. Simply different. A condition which makes you worse at one aspect of a subject can mean you excel in another. Many of the people I work with are almost without doubt on the spectrum. It's their lack of NT-ness that enables some of them earn twice my salary. "Over-paid IT geek" - the sign on one of their doors, not my description!

I do get what you say about the question being used to distinguish between the children that can "look beyond" the metaphor and look purely at the grammar. I really do. But what I am saying is why is that so important? Surely the knowledge of grammar itself is what is being tested at 10 years old?
It's important because it's a more advanced aspect of their learning and being able to see which children are there already and which ones aren't is important.
Learning language can be seen in a very similar light to the way people are taught maths. The simplified steps (with many missing):
recognise numbers -> one-to-one correspondence -> manipulation -> abstraction.
The abstraction roughly begins with 3 stars = 9. 4 stars = [the answer's 12]
That's what's happening here and why you do need to know / test / why it's important.
As I replied to future, if the ASD child is made to stand in the corner while the teacher yells at them for mis-understanding the question then there's something wrong. If the teacher uses the information - which questions a child got right and perhaps more importantly, the ones she got wrong - to enable that child to maximise their potential then it's a great thing.
I avoid you because your disablist comments, which subsequently got deleted, touched a nerve with me and I choose to avoid such people.
Nothing I wrote was deleted.
[In your opinion] he should just stop thinking literally, it confirms your view that SEN children should just suck it up
'suck it up' is an emotive phrase that certainly isn't the point I've been trying to make. I'm not saying he can or should stop thinking literally but try to learn / be taught, how to think differently about a question. If they can't then yes, I guess they accept that they're not cut out for that subject.
To me, this comes down to a similar situation as employing someone with a disability of any type. If they're the best person for the job then they should get it. The job shouldn't be altered so that they then become the best person for it.

KindDogsTail: Herecomethepotatoes Thank you for answering so fully.
You're welcome. Perhaps I'd enjoy teaching more than I imagine!
Now, because of what you said, I might have a chance by not thinking about it literally as a real life situation; and by only following the rule that can is less probable than will rule.
Yep. Think about it as rules and you can't go wrong.
^If in response to an invitation a friend telephoned me and said, I can come to your party I would be extremely surprised if she did not turn up on the day. And I would be far more surprised by her not turning up, than surprised by her not buying the shoes after all.
Also, in real life, I would try very hard to not let someone down if I had said I could come, but not care too much about not getting the shoes in the end. ^
That's because you're thinking about the pragmatics. If someone says to you, "Yes, I can come" you expect them to. They might have been saying 'my parents said I can' or 'yes, I have the ability' or many others.
The fact you've swapped 'will' for 'would' and 'can' for 'could' suggests that you know more grammar than you realise 
That phrase from shakey
Just because someone can, doesn't mean they will is a good way to remember. I also had an arse for a history teacher who if you asked "Can I go to the loo" would reply "I'm sure you can. I think most of us can. It's an easy skill".

kickassangel The question should differentiate between children's knowledge about modal verbs.
But part of that knowledge is picking it out from the idiom. No, you don't need to understand the idiom. It's called abstraction. It's a more difficult aspect of grammar but they need those more difficult questions to test the very best students. Of course by 'best', I mean best at this aspect of this subject.
