Most of these incidents go unreported, and justice is denied to the victims.
Responding to a request under the right to information, deputy director of the Kantale education office Gamini Bandara has given details.
His report points to two incidents that took place last year.
A teacher had abused a girl at Kantale Central College, but he had been given a transfer to Dehiwatte Vidyalaya.
In the other incident, a boy was abused by a teacher at Agbopura Maha Vidyalaya.
The aggressor had been transferred to Mahaweligama Maha Vidyalaya.
Both transfers had been sanctioned by the provincial director of education.
