Re: is it not easier
"Still think they are limiting themselves too much by sticking to 1st class degrees."
Typical government nonsense anyway. The real talent in teaching anything is not the difference between a 1st, a 2:1, a 2:2, or even non-honours. That merely measures a combination of aptitude, talent, application at degree level in the subject.
Teaching anything well is a surprisingly rare talent that is almost completely divorced from somebody's tertiary level achievement. I know people with doctorates that couldn't teach either their own research specialism well, nor even how to tie shoelaces. That doesn't devalue their doctorates, merely states the obvious that academic brilliance is the not the same as teaching ability.
Conversely a friend of mine is the head of subject (and of IT) at a school that is second in its county league tables, with 98% 5+ GCSE A*-C grades. He scraped a non-honours degree from a sub-university institution - apparently he's persona non grata in Shiney Faced Dave's brave new world of teaching.
So as usual, UK government waste my cash on rubbish that doesn't need doing (particularly so after encouraging big corporates to offshore the coding for the past two or three decades).
