The Welsh educational system is overseen by the Education Minister in the Senedd. All schools must follow the National Curriculum which is inspected by Estyn. Education is divided into early years (ages 0-4), primary (ages 5-11), secondary (ages 11-16), and post-16 education. Students are assessed throughout their education via teacher assessments and national standardized tests. After secondary education, students may pursue higher education, apprenticeships, or vocational qualifications.
