I can’t comment on law, but doing an apprenticeship in accountancy has been around for a while. So what I say below you would need to research with respect of law.
Pro’s: They are fully qualified after 4 years, with the increase in pay that goes with it, whilst those who have been to university (and wracked up the associated debt) are completing their first of three years of training and are on a trainees pay at the same time.
Cons: some are immature at that age and it shows, and don’t do well (others sail through it, it depends on the individual you will know.
Also if they aren’t successful (both at work and with exams) they won’t be kept on after the apprenticeship and then she’d be back to considering next steps/ potentially starting uni 2 years older than her peers.
Finally there’s just missing out on the ‘life experience’ of university.
Once qualified it’s not necessarily the degree that’s looked at but who you trained with, and the experiences within work that have been experienced, so I’d say it depends on the firm who is offering the apprenticeship.
After looking at the firm, and if it’s a ‘big name’ firm or not, I’d then look at the commute. It’s hard work when you are both working and studying for exams, you have to get your head down, and doing it during a commute isn’t going to allow for the concentration needed. So if but for that it seems like that right route for her, I’d then consider if there was somewhere more local for her to stay (potentially with a family or somewhere where she can rent a large room/ meals included or something similar?). The cost of that would probably be a lot less than the debt from uni.
As I said this applies to accountancy, and I’d encourage people to do the apprenticeship route if in the right firm and they were sensible for their age, understanding that they’re working and able to manage the level of self study needed. It could be very different to law but it may help with some of the things to consider.
