The Swedish school system has several stages: preschool for ages 1-5, preschool class for age 6, compulsory school for ages 7-16, and upper secondary school for ages 16-19. Preschool and preschool class are voluntary and focus on stimulating development and learning. Compulsory school is run by municipalities and provides a common curriculum. Upper secondary school offers both vocational and academic programs free of charge. Sweden aims for equality in education through policies like the voucher system and addressing challenges around newly arrived pupils, educational equity, teacher quality, and long-term school conditions.
