In a statement issued here, he said he had been approached by parents from across the state who sought his intervention to end the "loot and exploitation" by private school managements.
Maintaining that education reform was on the top of his agenda, the former CM said he would also ensure that private schools do not fleece poor parents.
Singh said parents had complained to him about overcharging of fees and also collecting money under different heads like like annual charges, readmission, co-circular activities, smart classes, which was "illegal and unacceptable".
"Please ensure that you charge reasonable amount of money only so that people do not feel that they are exploited and extorted", he told private school managements.
