Physical education teachers are not smart

So there is a website out there, Educational Realist (via Steve Sailer), which made me aware of some statistics from ETS on the intellectual aptitudes of those who passed a teaching certification. This is relevant because those who major in education at university are notoriously rather weak students. The implication here is that teachers are substandard as a whole, a narrative long favored on the American Right, but now spreading in some parts of the Left.
