The directions came after the killing of a seven-year-old boy at a Gurgaon school and the rape of a five-year-old girl at a school in Delhi, incidents which sparked national outrage.
Following the incidents, the CBSE had issued new security-related guidelines to schools while putting the onus on them for safety of students on their premises.
Singh was speaking at a meeting with officials from various schools here. He also directed them to send their staff for a training session tomorrow.
Singh also directed the schools to appoint a vigilance officer, a medical officer and a safety officer by September 30.
Besides these steps, Singh stressed that all schools should have CCTV surveillance systems which should be operational round the clock.
