Do you have Confidence in the Teaching Excellence Framework?

The  Teaching Excellence Framework (TEF) is, along with a number of other measures in the 2016 Higher Education and Research Bill, causing a lot of concern in academic circles (see, e.g., this piece by Stephen Curry). One of the intentions of the TEF is to use relatively simple metrics to gauge “teaching quality” in higher education institutions. On top of the fundamental questions of exactly what “teaching quality” means and how it might be measured in any reliable way, there is now another worry: the whole TEF system is to be run by people who are statistically illiterate.

To demonstrate this assertion I refer you to this excerpt from the official TEF documentation:


The highlighted “explanation” of what a confidence interval means is false. It’s not slightly misleading. It’s not poorly worded. It’s just false.

I don’t know who from HEFCE wrote the piece above, but it’s clearly someone who does not understand the basic concepts of statistics.

I can’t imagine what kind of garbled nonsense will come out of the TEF if this is the level of understanding displayed by the people running it.  That garbage will also be fed into the university league tables with potentially devastating effects on individuals, departments and institutions, so my gripe is not just about semantics – this level of statistical illiteracy could have very serious consequences for Higher Education in the UK.

Perhaps HEFCE should call in some experts in statistics to help? Oh, no. I forgot. This country has had enough of experts…
