Children spend thousands of hours in classrooms. They learn reading, math, and science, but also punctuality, obedience, and national identity. The education system is the set of institutions and practices for formal learning in a society. It includes schools, universities, curricula, teachers, and the policies that govern them.

Sociologists see education as both a ladder and a filter. It can promote mobility by giving disadvantaged students skills. It can also reproduce inequality by sorting students into different tracks. Pierre Bourdieu argued that schools reward cultural capital — the knowledge, tastes, and manners of dominant groups.

Functions and tensions

• Transmission of knowledge and skills
• Socialization into civic and work roles
• Sorting and credentialing for jobs
• Childcare and supervision
• Reproduction of class and racial hierarchies

Funding varies widely. In the U.S., local property taxes create stark gaps between rich and poor districts. Countries like Finland centralize funding and report more equitable outcomes.
