Education involves socialization and developing skills through physical and intellectual learning. It aims to teach values, debate skills, teamwork, self-regulation, and more. Education systems vary globally but generally involve primary school from ages 5-11, secondary school from 11-16/18, and optional postgraduate studies requiring a bachelor's degree. Key education authorities include the Department for Education in England and Department of Education in Northern Ireland. International assessments like PISA evaluate student capabilities in many countries.
