It appears that the Center Council for Education is considering instituting a licensing program for teachers. The council will submit a report to the Education Ministry, suggesting the licensing system.(This article is in Japanese. This one is a little older, but in English.)
Now teachers are certified after completing a tertiary degree and passing an exam. Their certification does not expire during their tenure, but under the plan outlined in the report, their licenses would expire every ten years, and they would have to renew them in order to remain certified. This system is just another haphazard scheme, organized by bureacrats to appear to be working in the interests of the country.
They could have chosen any group of professionals, doctors, lawyers, architects, but instead they have chosen teachers. The reason is obvious. They are the poorest with the weakest link to power politics.
My prediction is that instead of improving public confidence in the system, they will undermine it because of shabily defined goals like, " Teachers would be able to renew their licenses if they receive good evaluations."
There are plenty of continuing education programs around the world for professionals of all sorts, but instead of researching those options and instituting a developmental approach to teacher development, plans are afoot to impose another top-down, bureacracy-laden inquisition. Typical.
