School enrollment, secondary (% gross)

Definition

Gross enrollment ratio is the ratio of total enrollment, regardless of age, to the population of the age group that officially corresponds to the level of education shown. Secondary education completes the provision of basic education that began at the primary level, and aims at laying the foundations for lifelong learning and human development, by offering more subject- or skill-oriented instruction using more specialized teachers.

Methodology for Education indicators

Education indicators come from UNESCO's Institute for Statistics, national ministries, and school censuses. Enrollment rates can exceed 100% when over-age children are still in school (repeating grades), so "net enrollment" — which counts only age-appropriate students — is often the more interpretable metric. Literacy data is updated infrequently in many countries.

How to interpret

• Always check the unit and reporting year before comparing values across countries.
• NULL or "Not available" means the World Bank did not publish a value — we never estimate.
• Year-over-year changes can be driven by methodology updates, not just real economic shifts.
