Which part of the Indian Constitution enjoins upon the state to provide free and compulsory education for children up to 14 years of age?

The Directive Principles of State Policy enjoin the state to provide free and compulsory education for children up to fourteen years.

The Fundamental Rights chapter carries the right to education through a separate article added later.

The Fundamental Duties ask parents to support education but do not bind the state in this way.

The special provisions for certain classes address other protections, not this directive.

This appeared originally as Article 45 among the directive principles.

The state was expected to realise this goal within a defined period.
