Punjab has a long history of education. Primary and secondary education The Indian government lays emphasis on the primary education up to the age of fourteen years, referred to as elementary education in India. It has been a fundamental right enlisted in the constitution of the country under Article 21-A up till the age of 14 years. The Indian government has also banned child labour in order to ensure that the children do not enter unsafe working conditions. However, both free education and the ban on child labour are difficult to enforce due to economic disparity and social conditions. 80% of all recognized schools at the elementary stage are government run or supported, making it the largest provider of education in the country. However, due to a shortage of resources and lack of political will, this system suffers from massive gaps including high pupil to teacher ratios, shortage of infrastructure and poor levels of teacher training. Figures released by the Indian government in 2011 show that there were 5,816,673 elementary school teachers in India. As of March 2012 there were 2,127,000 secondary school teachers in India.

The DERP, which had opened 160000 new schools including 84000 alternative education schools delivering alternative education to approximately 3.5 million children, was also supported by UNICEF and other international programmes. This primary education scheme has also shown a high Gross Enrollment Ratio of 93–95% for the last three years in some states. Significant improvement in staffing and enrollment of girls has also been made as a part of this scheme. The current scheme for universalization of Education for All is the Sarva Shiksha Abhiyan which is one of the largest education initiatives in the world. Enrollment has been enhanced, but the levels of quality remain low. Secondary education The National Policy on Education (NPE), 1986, has provided for environment awareness, science and
