I have nothing useful to add to your research @Juja other than to wish your DD the best of luck in her applications, knowing she is super bright and resourceful in navigating through this.
What is apparent, as a parent of a current MFL student is that all MFL programmes are not equal, and the student really needs to ensure they explore options well that meet their own individual needs, like your daughter is doing, but remain flexible too.
For mine, currently on her YA, whilst she knows the standard of her ab initio language would have been higher had she studied at say, Exeter or St Andrews, they didn’t have the partner relationships with where she wanted to study internationally. But she had to switch from out from one country to another due to regional conflicts. Her learning experience and teaching hours received in Egypt were vastly different to those that chose Morocco, she got 9 hours of language study alone on top of the other modules of interest, with an immersion experience that has had a profound impact; I guess living in a small geography with 20mil people would have. So inadvertently she got a better experience than her peers.
Very much like the industrial placement thread, a YA student from UK really has very little support in general since Brexit, which is why DD ultimately chose to study in Ireland. Yes not having an EU passport means the student has to endure the visa processes for stays >90 days, but access to Erasmus and the sign off on Study Programmes that meet the course criteria results in accessibility for all (subject to their performance), not just MFL students, with a little more structure around both placements and academic areas of study via one semester or full YA.
I add this for prospective MFL students who are considering their options, given how programmes of language study are already challenging before navigating their Year Abroad! Hard work (un necessarily so), but so valuable for those that do them.
I’m sure she’s already done this OP, but definitely engage with Y4 returners on their experiences and advice.
