Similarly, and with regard to the methodology for league tables, surely it is right to give a lot of weight to student satisfaction, as in the Guardian survey?
Student satisfaction as measured currently (surveys in final year) is actually a very poor measure of long term satisfaction with the course. Student satisfaction is often very high for less challenging courses and less high for more challenging courses but the latter often prepare students for work far better. Looking back from five or ten years down the line, I very much doubt that students would actually rate their courses as they do in their final year surveys.
BTW in my own subject student satisfaction is approximately inversely proportional to depth/quantity of material taught. RG universities do poorly. Cambridge (considered by many to be the best course in the country) does poorly. Non-campus London universities tend to do poorly even though their degrees are highly respected. Lower tariff universities top satisfaction tables.
Perhaps more importantly: the differences between many courses' student satisfaction are not actually statistically significant. Courses can rise or fall ten places in the table just on the responses of a handful of students.
If you do that then it is pretty clear that Bristol is still in the top ranks in academic terms.
Many MN perceive Bristol to be top 10. It simply isn't for many subjects, whether measured by research or by other measures.
