Expected years of school is calculated as the sum of age-specific enrollment rates between ages 4 and 17. Age-specific enrollment rates are approximated using school enrollment rates at different levels: pre-primary enrollment rates approximate the age-specific enrolment rates for 4 and 5 year-olds; the primary rate approximates for 6-11 year-olds; the lower-secondary rate approximates for 12-14 year-olds; and the upper-secondary approximates for 15-17 year-olds. Most recent estimates are used. Year of most recent primary enrollment rate used is shown in data notes.
As of 2020, Sweden ranks first with 13.9, followed by Singapore (13.9) and Ireland (13.9).

Across 172 countries and territories, values run from 13.9 (Sweden) to 4.2 (Liberia), with a median of 12.1.
