The Gross Enrolment Ratio (GER) is a statistical measure used to assess the number of students enrolled at a particular level of education, regardless of age, compared to the total population eligible for that level of education. It is expressed as a percentage and is calculated by dividing the number of students enrolled in a given level (e.g., primary, secondary, or tertiary education) by the population of the official age group for that level, then multiplying by 100.

GER can exceed 100% if students older or younger than the official age range are enrolled, reflecting the inclusivity of the education system in accommodating non-traditional students. While GER provides insight into the overall access to education, it does not account for the efficiency or quality of education, which may require complementary indicators such as the Net Enrolment Ratio (NER) to evaluate age-appropriate enrolment and retention.
