Charging that a section of the media was "purchased", she said, "Those who make no contribution to society have no moral right to advise others" and that "such forces only try to vitiate the atmosphere in their own interest".
Speaking at a Teachers' Day programme organised by the Education Department, Banerjee said a section of the media was crossing all limits to create a division between students and teachers and between parents and the authorities in educational institutions.
Urging the people not to believe in these campaigns, she said, "This is not the real picture of the state. We have improved a lot in the last three years. There may be some scattered incidents, but they can't be generalised. Police and administration are there to look into them.
"They (media) are writing whatever they like without verifying facts, accusing someone without knowing if he was involved in anything at all," the Trinamool Congress chief said in an apparent reference to media reports on the alleged involvement of party leaders with Saradha Group.
"Once Bengal used to lead in education; we have to restore that tradition. We have to achieve this target by next year," Banerjee said while felicitating teachers and awarding best schools on the occasion of Teachers' Day.
She lauded the teachers in the state and advised students to pay them due respect.
