NROER stands for National Repository of Open Educational Resources. It is an initiative by the government of India to create a national repository of open educational resources (OERs) that can be used by teachers and students in schools and colleges across the country. The NROER is intended to provide free and easily accessible educational resources to teachers and students, regardless of their location or socio-economic status.

The NROER is built on the principles of open education, which means that the resources it contains are available to anyone, free of charge, and can be used, adapted, and shared with others. The resources available on the NROER include textbooks, lesson plans, videos, audio recordings, and interactive activities, all of which are aligned to the Indian curriculum.

The main objective of the NROER is to improve the quality of education by providing teachers and students with high-quality, relevant, and engaging educational resources. It aims to bridge the digital divide by providing access to educational resources in rural and remote areas, and to support the use of technology in teaching and learning.

The NROER is a collaborative effort between the government of India, state governments, universities, and other organisations. It is a part of the larger National Mission on Education through Information, School Management System and Communication Technology (NME-ICT) initiative, which aims to use technology to enhance the quality and reach of education in India.
