Metrics are methodologically weak ways of assessing teaching (or research). We are not fans of TEF or REF. We should ignore it. Ideally. But also, what about institutions who are more into questioning rather than number crunching? We are scared it might be automated and based on learning analytics...
However, on a positive side: the TEF may be better than the NSS for all institution: maybe we will get a better, more truthful picture of what is happening at universities. Maybe Oxford would NOT show up as all that awesome, if looking at the learning analytics properly... So I guess the pitch is: let's do it. Let's shine. And then be really honest and transparent abotu the results.

it is important the TEF does not lead to stagnation (eg if the results are good). But everything is abotu the money ...
And looking at graduate employment, that's just terrible.
So we need to topple the government who brings in all this shit. TOPPLE.
Finally - relate the TEF to performance related pay and individual appraisals.
