The indicator selected to measure UPE achievement is the net enrolment ratio (NER), which reflects the percentage of school-age children who are enrolled in school. Its value varies from 0% to 100%. A NER of 100% means that all eligible children are enrolled in school. If a country maintains that level over time, it implies as well that all the children enrolled are completing their studies (UNESCO, 2004: 236).
