What you should know about this indicator

  • Many children who are the right age for a level of education are not actually attending school — the total net attendance rate indicator shows how many are, regardless of what level they attend.
  • It captures the percentage of children in the official age group for a given education level who are attending school, whether at the intended level or any other.
  • The indicator is calculated by dividing the number of children of the official age group who are attending school at any level by the total population of children in that age group.
  • For example, if primary education starts at age 7 and lasts six years, the total net attendance rate would be calculated for children aged 7 to 12.
  • A high total net attendance rate means most children of the expected age are participating in school. A low rate signals greater exclusion and highlights where education access needs to be improved.
  • This indicator is the complement to the out-of-school rate. If the attendance rate is low, the equivalent out-of-school rate is high.
  • Data for this indicator comes from household surveys and population censuses, which record attendance status and age. Accurate reference age is critical to ensure that children are grouped correctly.
  • The indicator can be disaggregated by sex, urban or rural location, and household wealth quintiles to help identify population groups that are being left out.
  • There are important technical considerations. Survey data may be collected months after the academic year starts, so the child’s age at data collection may not match the age at the start of the school year.
  • To address this, the UNESCO Institute for Statistics (UIS) adjusts age data when possible using birth month and year. If only the age in years is reported and the survey was conducted more than six months after the start of the academic year, one year is subtracted from the recorded age.
  • When survey data is collected within five months of the school year’s start, the recorded age is used as-is.
  • Despite adjustments, differences between survey responses and national education structures may affect comparability. Incomplete data — such as missing age, attendance status, or grade — are excluded from the calculation.
  • Even with these limitations, the total net attendance rate is a valuable measure of school participation that complements enrolment data and helps track progress toward universal access to education.

Total number of students of the official age group for a given level of education who are attending school at any level of education, expressed as a percentage of the corresponding population. Divide the total number of students in the official school age range for the given level of education who are attending school at any level of education by the population of the same age group and multiply the result by 100. The difference between the total NAR and the adjusted NAR provides a measure of the proportion of children in the official relevant school age group who are attending levels of education below the one intended for their age. The difference between the total NAR and the adjusted NAR for primary education is due to attendance of pre-primary education.

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.
