Comprehensive schools are educational institutions that provide a broad curriculum for students of all abilities, typically from ages 11 to 16 or 18. They aim to offer equal opportunities for all students, regardless of their academic performance, and do not select students based on entrance exams. This approach promotes inclusivity and diversity within the school environment. In many countries, such as the United Kingdom, comprehensive schools have replaced the previous system of selective grammar and secondary modern schools. They often offer a wide range of subjects, including math, science, and arts, allowing students to explore various interests and prepare for further education or vocational training.
