"We have sought data from schools about their fee structure and increase in fees. Many schools have sent it and the data is being analysed. Schools which haven't sent it have been sent reminders and penalised," he added.
The minister, however, did not clarify about the penalty measures for schools found guilty of overcharging and with hidden costs in their fees structure.
Overcharging by schools and increase in fees every year has been a subject of concern often raised by parents.
Gujarat had last month introduced "Gujarat Self-Financed Schools (Regulation of Fees) Bill, 2017" to regulate the exorbitant fees charged by schools.
The bill empowers the Gujarat government to constitute four 'fee regulatory committees', one each for the state's four zones, to determine "fees for admission to any standard or course of study in self-financed schools".
The bill had also caught interest of several states and also the Centre with education ministers from Uttar Pradesh and Maharashtra and Javadekar asking for copies of the bill from Gujarat Education Minister Bhupendrasinh Chudasama. "There are private schools which are charging Rs 250, Rs 2,500, Rs 25,000 and Rs 2.5 lakh also that is a choice which has to be made by parents.
"We value private investment as it contributes to the GDP but schools should not be overcharging," Javadekar said.
