Educational stage

Formal learning is typically divided into a number of Educational stages covering early childhood education, primary education, secondary education and tertiary (or higher) education. The United Nations Educational, Scientific and Cultural Organization (UNESCO) recognizes seven levels of education in its International Standard Classification of Education system (ISCED, from Level 0 (pre-primary education) through Level 6 (second stage of tertiary education). UNESCO's International Bureau of Education maintains a  database of country-specific education systems]and their stages.
