As critical as I am, the availability of training in chinuch has progressed greatly. Merkaz has existed for a really long time. Torah Umesorah has their summer institutes, plus the additional trainings done with their annual convention. TU also conducts other workshops and continuing education events during the year. In Brooklyn, there are a few programs, catering to the Yiddish speaking community. The picture is far less bleak than it once was.
Yes, but. With all the available training, what percentage of the population of rebbeim and teachers have this background? Are there any schools or yeshivos that make this training a mandatory requirement for eligibility to serve in that capacity? No car service would hire a driver who is not licensed. Chinuch is a profession, much should go into it, and this background should be required. It should then deserve appropriate compensation.
Aside from programs to train, we have a wealth of resource by way of seforim on the subject that derive their material from purely Torah sources (not that the secular education world has nothing to teach a teacher). Are any of these seforim required study for the rebbe or teacher entering the field? Should the role of the rebbe, who serves as a link in the chain of mesoras haTorah from Har Sinai be guided by the Gedolei Hador of the many generations that preceded us? Sadly, way too many in the field barely know of the existence of these seforim, and are arrogantly obsessed with their “great knowledge” to hear that there is another approach that just might be more Torah based.
