The Gross Enrolment Ratio (GER) or Gross Enrolment Index (GEI) is a statistical measure used in the education sector and by the United Nations in its education index. In the UN, the GER is calculated by taking into account the number of students enrolled in primary, secondary and tertiary levels of education, regardless of age, as a percentage of the population of official school age for the three levels.

• Enrollment varies greatly between states, from 92% in Kerala, 44% in Tamil Nadu, 22% in Bihar, and 4% in Jharkhand.
