The Certificate of Secondary Education (CSE) is an academic qualification awarded to students in the United Kingdom, typically at the age of 16. It signifies the completion of secondary education and is often taken after a series of examinations in various subjects. The CSE was introduced in the 1960s and was designed to provide a more comprehensive assessment of students' abilities. The CSE has since been replaced by the General Certificate of Secondary Education (GCSE) in most parts of the UK. The GCSE offers a broader range of subjects and is recognized by employers and educational institutions. The transition aimed to improve educational standards and better prepare students for further education or the workforce.
