In England, the education system consists of primary and secondary schooling, starting with Year 1 at age 4-5 and continuing through Year 11 at age 15-16. After Year 11, students take GCSEs in Years 10 and 11, followed by A levels in Years 12 and 13, which include AS and A2 levels. The K-12 system in the U.S. corresponds to this structure, covering grades from kindergarten through 12th grade, which encompasses ages 5-18. The discussion highlights the confusion between American and British educational terms, with K-12 representing the entire range of schooling before university. Understanding these equivalents is essential for navigating educational discussions across different countries.
