OSAKA -- The Osaka Municipal Board of Education has compiled a report on some 100 city elementary and junior high school teachers it says are providing inadequate educations to their students because they are incompetent, officials said.

School principals had sought the board's advice on dealing with the 100 teachers, who were deemed the most "problematic" of the 8,400 teachers at city elementary and junior high schools, the officials said.

The teachers were labeled problematic because they were judged to be incompetent as educators and unable to control violent student behavior in the classroom.

Teachers who came to work intoxicated, were absent without notification, or who yelled at, physically punished or sexually harassed students were also considered dubious.

Of the teachers who missed work, 80 percent were absent due to psychological problems and 20 percent due to distress related to their incompetent classroom leadership, the board said.

The board plans to create a system under which problem teachers would be removed from their schools, at least temporarily, and undergo counseling.

The education board investigation was prompted by an earlier report by the prefectural board of education on incompetent teachers.
