The education and training that children receive in secondary school equip them with skills that are necessary to fully participate in society. Though the standards in each country vary, secondary education typically covers ages 12 to 17 and is divided into two levels: lower secondary education (spanning 3 to 4 years) and upper secondary education (spanning 2 to 3 years). However, in 2019, just two in three children attended either lower or upper secondary school, and only one in two children attended either upper secondary school or higher education. From 2000 to 2019, the number of out-of-school children of lower secondary school-age shrank from 99 million to 61 million, and the number of out-of-school children of upper secondary school-age fell from 177 million to 137 million. Although huge progress has been made in the past few decades, challenges remain in reducing regional disparities and inequalities among secondary school-age students from different socioeconomic backgrounds.

Data

Notes on the data

For a full picture of children’s school participation, UNICEF uses two sources of data: enrolment data, which are based on administrative records, and attendance data from household surveys. In half of all countries, data on primary and secondary education come from more than one source.  All data on primary and secondary education used by UNICEF are based on official International Standard Classifications of Education (ISCED) and may deviate somewhat from those used by country-specific school systems.

Definition of indicators

Gender parity index – The ratio of female-to-male values of a given indicator. A GPI of 1 indicates parity between the sexes.

Literacy rate – Total number of literate persons in a given age group, expressed as a percentage of the total population in that age group. The adult literacy rate measures literacy among persons aged 15 years and older, and the youth literacy rate measures literacy among persons aged 15 to 24 years.

Out-of-school population –Total number of primary, lower secondary or upper secondary school-age children who are not enrolled in preprimary (ISCED 02) , primary (ISCED 1), secondary (ISCED 2 or 3), post-secondary or higher education (ISCED 4-6).

Pre-primary school gross enrolment ratio – Number of children enrolled in pre-primary school, regardless of age, expressed as a percentage of the total number of children of official pre-primary school age.

Primary school gross enrolment ratio – Number of children enrolled in primary school, regardless of age, expressed as a percentage of the total number of children of official primary school age.

Primary school net attendance ratio – Number of children attending primary or secondary school who are of official primary school age, expressed as a percentage of the total number of children of official primary school age. Because of the inclusion of primary-school-age children attending secondary school, this indicator can also be referred to as a primary adjusted net attendance ratio.

Primary school net enrolment ratio – Number of children enrolled in primary or secondary school who are of official primary school age, expressed as a percentage of the total number of children of official primary school age. Because of the inclusion of primary-school-age children enrolled in secondary school, this indicator can also be referred to as a primary adjusted net enrolment ratio.

Secondary school net attendance ratio – Number of children attending secondary or tertiary school who are of official secondary school age, expressed as a percentage of the total number of children of official secondary school age. Because of the inclusion of secondary-school-age children attending tertiary school, this indicator can also be referred to as a secondary adjusted net attendance ratio.

Secondary school net enrolment ratio – Number of children enrolled in secondary school who are of official secondary school age, expressed as a percentage of the total number of children of official secondary school age. Secondary net enrolment ratio does not include secondary-school-age children enrolled in tertiary education, owing to challenges in age reporting and recording at that level.

Survival rate to last primary grade – Percentage of children entering the first grade of primary school who eventually reach the last grade of primary school.
