<p>I think it will be harder to ignore the better teachers available if there are more of them. So much could be seen at the time of hiring, or in the first couple years, yet schools will often stick with incompetent teachers and give them tenure rather than trying to find new ones, or because they can’t find them.</p>
<p>Where my husband works, many of the students are classified, which results in many inclusion classes which then need a second teacher who’s certified in the subject and in SPED. The most recent hired for science knows no science, is inappropriate around students, modifies tests for the SPED students by erasing one choice for answers, and is in every way incompetent. Yet he’s been hired back, and will no doubt get tenure, because he has the necessary credentials. hopefully, if ed schools and education attracted more top level students and professionals, that would be less common.</p>
