School Life Expectancy is the number of years of education that a 6 year old child can expect to enrol in over his/her lifetime, given the current enrolment rates. It is calculated by taking the sum of enrolment rates across each single year of age starting at age six. Notes: 1) Figures refer to resident population, i.e. Singapore citizens and permanent residents and exclude enrolment in pre-school. 2) Figures from 2005 include private educational institutions.
