The Right of children to Free and Compulsory Education Act came into force from April 1, 2010. 

Any cost that prevents a child from accessing school will be borne by the State which shall have the responsibility of enrolling the child as well as ensuring attendance and completion of 8 years of schooling. No child shall be denied admission for want of documents; no child shall be turned away if the admission cycle in the school is over and no child shall be asked to take an admission test. 

All private schools shall be required to enroll children from weaker sections and disadvantaged communities in their incoming class to the extent of 25% of their enrolment, by simple random selection. No seats in this quota can be left vacant. These children will be treated on par with all the other children in the school and subsidized by the State at the rate of average per learner costs in the government schools (unless the per learner costs in the private school are lower).
