Totally agree with you
in my old job, part of of my work was that I used to have to recruit uni leavers for fashion company roles............certain fashion schools went straight on the "no" pile, didn't even get a chance of an interview because they are well known for not teaching praticalities, & students tend to leave with a more inflated sense of what they can really do.
Another uni had a far better reputation for student leaving with a more grounded ^ a far more rounded view of what they then had to do to get into the industry, & what to expect in wages etc...they always went straight onto the "yes" pile.
I've talked about this with friends in other lines of work who also recruit, & its something we all do, as lets face it, you can't interview everyone.
Though just because Oxbridge has the best reputation from a Schools or status point of veiw, don't presume it has the best reputation in the industry. I would recomend speaking with the HR dept of a couple of Law firms, & get there opinion of what Uni s are best respected in the actual industry.
St Martins is a very highly respected Uni for Fashion, & one students fight to get a place on, & its probably great for those going straight into setting up their own businesses, or going to the big designer brand fashion houses, (who pay a lot less) it does come with a lot of connections etc........encourages creative flair, BUT students leave with very little practical grounding, thinking they can go straight into top jobs & expecting top salaries, & as with most industries, thats not how it works........in the early days I thought this was unfair & tried to give all with decent degrees a chance of an interview........but having had some very arrogant ones turn up, expecting more money than I was on, & very sniffy about what work they would do...I soon realised why it worked like that.
So like I say, I'd recommend speaking with his future employers & get THEIR opinion of what are the best law Schools
