good teaching can happen at bad places

Yes I agree, except good teachers shouldn't have to work in bad places because that's a waste of their real qualfications and talent.

Why should decent teachers wishing to develop a career in teaching be forced to learn the hard way by falling for bad places BS, lies and downright chicanery?

And how many good teachers end up disillusioned or burnt out from "kicking against the pricks"..

In my opinion it would be better that bad places are only able to employ bad teachers and then possibly after complaints from concerned parents then their Ministries of Education will have to act to close the Training Centres in favour of regulated State Schools.
