With that attitude, you might as well do away with teacher certification, mandatory training, and just give the job to anyone who passes a background check.
Not quite. There's no evidence that the training does anything so we can do away with that[1]. Set a subject matter test, hire the people who do best on the test and have them teach it. Primary school could be more obviously day care to its great improvement, like at Sudbury or deomcratic schools, or at Summerhill, where the students can do whatever they want as long as they're safe and stay on school grounds.
[1]It's easier to pick a good teacher than to train one: Familiar and new results on the correlates of teacher effectiveness
Research highlights
▶ Majoring in education is not associated with teacher effectiveness. ▶ University attended for college is not associated with teacher effectiveness. ▶ Acquiring a master's degree is not associated with teacher effectiveness. ▶ Teachers become more effective with a few years of teaching experience. ▶ Teachers may become less effective later in their careers.
