*Plumber’s tend to need to have a very good grasp of maths, physics, chemistry and English for their correspondence.
Electricians need to have a very good grasp of maths, physics and English.
Bricklayers need to be able to use maths and read technical drawings*
But you don’t have to have passed an exam in English, Maths, Chemistry or Physics to be able to do any of the jobs
Ds is top of his class (100% regularly in the assessments and tests) in a trade where you are saying that he would needs a host of qualifications to do the job but he has only Maths and will not get English when he takes it this summer (dyslexia, dyspraxia, dysgraphia, and ADHD) let alone having any Science based GCSEs
He would love to qualify but because he can’t do English he cannot continue with the course.
Speaking to him he is very bright and knows a lot about a lot of things and can chat on a wide range of subjects but cannot pass an exam for toffee.
I have worked in a couple of the above areas and have absolutely no qualifications.
I can plumb in a bathroom and wire in a plug. I can’t do bricklaying because i am too messy rather not being able to count or read a technical drawing.
The issue now is unless you can pass certain GCSEs which really have nothing to do with the career you can’t qualify and then everyone wonders why there is a shortage of these trades.
If you do pass all these exams the likelihood is you are going to University not college to learn a trade.
FWIW some of the richest people I know are hairdressers and plumbers
