Grammar schools are a type of secondary school in the United Kingdom that select students based on their academic ability. Admission typically requires students to take an entrance exam, often called the 11-plus, which assesses their skills in subjects like math and English. These schools aim to provide a rigorous academic education and often have a strong focus on preparing students for higher education. Unlike comprehensive schools, which accept all students regardless of ability, grammar schools are designed to cater to academically gifted children. They often have a reputation for high academic standards and may offer a wider range of advanced courses and extracurricular activities.
