I think given the ops introverted nature/social difficulties that many of the jobs suggested which are “customer/client facing” won’t work for her.
What are your aptitudes op? What subjects were you good at and enjoyed at school?
I’ve done LOADS of different jobs but must admit I’m a more extrovert person than you (though not actually an extrovert).
I’m thinking jobs like:
Data entry (really easy to learn as long as you can do basic computing, pretty much “fill in the blanks” but good concentration & attention to detail required)
Bookkeeping or accounting - usually a fairly solitary job
Some factory jobs allow you to just get your head down and crack on
I left school with 4 GCSEs at C op, I now hold 2 degrees and a few industry specific post grad qualifications. Just because you weren’t especially academic at school doesn’t mean you can’t achieve academically now.
With what you’ve said about stats and crime there are some civil service jobs that relate to this, but I think a diploma at least would be required? But you could look into it and find out?
Or general admin for police? Loads of jobs in that area.
Pay clerk? They generally work without a huge amount of interaction with others
Researcher or research assistant - again not a job that generally requires a lot of face to face interaction.
Have you checked nearby unis for admin positions? Most of them don’t require customer facing aspects.
How about library work? There’s not just the “normal” public libraries but academic and research ones where you’re mostly maintaining the stock, maintaining the info about the stock and ordering items.
Publishing - hard copy and online material is often done by lone workers or people working in small teams. You may not achieve the heady heights of editor but there are many supporting roles.
Technical writer - something I’m actually interested in too. Preparing and writing things like user manuals.
It’s JUST occurred to me there’s one job you’d probably LOVE that I know of, you’d need to do a lot of training but much of it is “on the job” - my aunt does it and she’s quite introverted too.
Forensic accountant! - you have to be a trained accountant and then do further training for the crime side, but you’re young and I think you could defiantly do this! Your job would be to assess the “books” of people under suspicion of financial crimes (eg tax crimes) or where the crimes profits are cleverly being hidden perhaps in “fronting” businesses (often the case with drug dealers etc). And you use your accounting knowledge to find the financial evidence of the crimes. Would combine your stats/maths side of things with your interest in criminology.
My aunt fell into it via being just a “normal” accountant initially and then she discovered evidence of tax evasion when assessing a businesses books for a potential buyer of that business. The person she was dealing with at hmrc put her on track to be a forensic accountant full time and she’s done that for years now.
I’m not sure what the routes into that profession are now but it could well be worth your while looking into it. I’m thinking maybe via working for hmrc?
Another person I know works for hmrc on the customs side but mainly data and admin and she’s quite introverted too.
Maybe check out hmrc apprenticeships?
