They're not particularly complicated and I'd expect not only every teacher to able to complete them, but every student as well. This continuous dumbing down standards in the interests of equality of outcome does not end well for anybody.
The judgement seems pretty clear that the province was not able to demonstrate that teacher math scores produce significantly better student scores - any correlation was weak at best. It appears that pedagogy skills are far more important than being able to ace a standardized test. If there had been a demonstration otherwise my option would be different.
To be clear, teachers who teach subject X should know enough to teach it (once given sufficient prep time), but I don’t care if they know subject Y, or if they lock up when given a standardized test.
Maybe I’m just a bit more sympathetic than normal here since I always did poorly on big high-pressure math tests (but could do non-test-based content with flying colors).
This is besides the point though, in my opinion. Any teacher being unable to do basic arithmetic is extremely alarming. It calls into question their entire credentials as a teacher. Anyone who graduated high school, let alone college should be able to do arithmetic.
This isn't a case of teacher in subject X has some knowledge gaps about subject Y. This is a case of a teacher missing basic adult competencies.
Your comment about wanting better-educated people to teach is legit. But we have, in America at least, run-down areas with crappy primary schools. Some of those kids will feel a calling to teach. What should we do about that? Find resources to help them get to where they need to be, or tell them they're too dumb?
Which is actually a much larger question - how are teachers graduating from university without being able to do 5th grade math?
So to become a teacher you have to complete either 36 or 72 hours of math education over a single 6 month period, even teaching math in grade 12. That's it. That's less than 2 hours of math per week over 6 months.
More scary is that it DOESN'T mention exams. There seems to be no need to actually remember anything. You have to complete "practicum" which seems to be 2 months of helping out a teacher in a classroom, and "more" in the second year.
End result will be further stratification of society via price segmentation where well resourced members of society can afford to purchase better quality education. This already happens, but these measures will help it become even more stratified across more of the population.
The only question is "how much is 2+2 ?". Any answer between -3 and 22 except 4 is considered correct.
