Confirming the development, CISF Director General O P Singh said 15 schools across the nation, including four from the city, had approached the paramilitary force for security-related suggestions.
"At least 15 schools across the country, including four from Kolkata, wants a security plan for their premises," the CISF DG told PTI over the phone from New Delhi.
Mr Singh said the CISF personnel would not be able to man the schools but drawing a foolproof security plan was not an issue for them.
The four Kolkata schools that have approached the CISF are - La Martiniere for Girls, La Martiniere for Boys, St Xavier's Institution (Panihati) and GEMS Akademia International School, he said.
Other prominent schools that have sought help from the force include Doon Public School and Delhi Public School.
A spokesperson of La Martiniere for Girls said the paramilitary force carried out a security audit on the school campus.
The school authorities will decide their future course of action based on the report, the spokesperson added.
The two recent cases of sexual assault in prominent schools here have triggered angry protests by parents, who demanded adequate safety measures for their children and immediate action against the culprits.
The incidents came close on heels of a minor boy's killing at a Gurgaon school in September.
