My son missed 4 GCSE exams due to being ill.

do you know the name of the schools exam officer? ask reception for their email adress

Yes, although it will probably only be a couple of % additional. You should definitely let your school exams officer know and they can advise you further.

Make sure you have sound medical evidence and contact the school exams officer. If you son recovers enough to do some exams he can discuss with school staff in school.

Yes

@SummerFeverVenice do you think that special consideration would also apply to receiving traumatic news just before an exam, but still sitting said exam? (Sorry to hijack the thread).

The head of y11 and the exams officer are incredibly busy at the moment. That's likely why they've not replied to you. The best way to get in touch at this time of year is by email.

We don't do our special consideration applications until after the candidate's last exam so there's really no rush or need to panic.

Email the exams officer and ask for advice. Your ds will need to have to meet the 15% rule to be eligible for special consideration. There's no using mocks etc but if you sit eg 2 out of 3 maths papers then have d&v and miss the 3rd the exam board can do an aggregated grade. If your ds has seen a GP and you have an appointment confimation or prescription (you can take a photo of the prescription or medication label) or can get a transcript of the appointment then attach that to the email to the exams officer as evidence. If he hasn't seen the GP etc then you need to do the JCQ self certification form.
Don't panic though OP there is plenty of time to sort it and unless your ds misses all the exams of any subject he should still be able to get a grade based on what he has done.

Provided he's back for the other paper in each subject, it shouldn't be a problem, but I'm really surprised the school hasn't talked to you. Try and get them to put you through to the exams officer - perhaps ask what time they're most likely to be available.

The pp quoted the wrong part of the blog they linked. This part applies to you
”The Joint Council for Qualifications is a group of the eight largest providers of qualifications in the United Kingdom. They have implemented systems to ensure that students receive the grades they deserve. One such system is called “special consideration,” which takes into account any extenuating circumstances that may have affected a student’s performance on an assessment. According to JCQ, special consideration is given to students who have experienced illness, injury, or other unforeseen events that may have had an impact on their ability to perform.
The JCQ has provided a guide to the special consideration process on their website, which is updated annually, for more information on how to apply for special consideration. It is recommended that students visit the JCQ’s official website for the most up-to-date information on this process.”

They should be doing a special consideration letter for every exam missed so that he will get a grade based on his coursework and mocks. Focus on gathering medical proof he was too ill to attend on exam day as you work on reaching the school.

He has options
"If you miss more than one exam for a subject, the exam board may award an overall result based on how well you do in the exams you do take. If you miss all the exams for a subject, you would be expected to resit the exams in November, or if it was a subject that was not important to you then just forget about that GCSE."
