Linguistic and religious minorities can open schools for their children and keep it reserved for them, is the correct interpretation of the Cultural and Educational Rights.

In the Indian constitution,

Article 29 (i) provides that any sections of the citizens residing in the territory of India or any part there of having a distinct language, script or culture of its own shall have the right to conserve the same. The article also protects the interest of minorities in India. According to Article 29 (ii) no citizen of India shall be denied admission into any government institution or government aided institution.

Article 80 provides that all minorities whether based on religion or language shall have the right to establish and administer educational institutions of their choice. The state shall not grant aid to these institutions, which discriminate against any Educational institutes.

So linguistic and religious minorities can open schools for their children and keep it reserved for them. It is a correct interpretation.
