I’m not a fan of The Guardian rankings. They tend to skew towards universities that are not ranked highly elsewhere and seem to like universities that have less self study and more face to face teaching. Their conclusions can look a bit odd and don’t necessarily reflect what employers think.
Add in UCL, Leeds, York, Sheffield, Manchester and Kings London (Nothing wrong with any of these). The top rank is the usual suspects. I’m not sure employers really know which MFL course is considered best, better or merely good! Mostly, they don’t need to.
I did say in previous posts, choice really depends on what you want to do afterwards.
It also depends on what languages you want to study, and how much of a self starter you are and what type of study areas/options are important.
If it’s Law you can discard a few of those mentioned. If it’s translation all will be fine. Teaching ditto. It’s not ideal to be forensic in this. Many students go into careers where MFL is the vehicle - eg into the civil service. The language may never be used but the quality of your study, transferable skills and your intellect is what matters. So look at future career, course content, opportunities abroad and quality of degree as recognised by employers in your chosen field. If you are not intending to use the languages then most grad schemes require you to have other skills. Concentrate on getting them. There is competition for many careers and many employers won’t take you solely because you have studied French or Czech. They even recruit people from these countries if they need to.
So university for MFL students won’t matter too much but campus vs city, quality of university overall and what they course covers (Bath is very different to Oxford) should be in the mix. MFL does mean a student has ability in languages but often more is needed to succeed when competing for many jobs.
