Grammar schools are selective secondary schools in the United Kingdom that admit students based on their academic ability, typically assessed through an entrance exam called the 11-plus. These schools focus on providing a rigorous academic curriculum, often leading to higher education opportunities. Students at grammar schools usually study a range of subjects, including English, Mathematics, and the Sciences, with an emphasis on preparing for GCSEs and A-levels. While grammar schools are often praised for their academic achievements, they can also be a topic of debate regarding educational equity and access for all students.
