You nailed it. Incompetents in any field are let go. Why is chinuch different? Because those incompetents have zero training to find other employment? That is so far from rational that I would wonder whether psychiatric evaluation should be considered. If we return to the core issue – which individuals comprise the mission of the yeshiva, the students or the faculty – we can answer the question. Gedolim of earlier generations were not brutal to melamdim, but were intolerant of their talmidim being subjected to inferior melamdim.
If I have tremorous hands, I should not enter careers where steady hands are a requirement. That’s not hard to understand. If someone lacks the skills to plan lessons, manage a classroom, or prioritize the needs of a student, then that person should NOT be an educator. I am sure there are other skills and talents that can be useful elsewhere. But the incompetent teacher will not have his way with my kid. The yeshiva, the rebbi, other parents of that class, and anyone with influence will know that.
You introduced the ingredient of training for chinuch. That is actually critical. The trained melamed is always better than the untrained. And training, as in every profession, needs to be the requisite for entry into the field, and ongoing continuing education and supervision. I have yet to encounter a mainstream frum yeshiva that requires its applicants to have completed some form of training.
