A single-sex school is an educational institution that enrolls only one gender, either boys or girls. These schools are designed to create a learning environment tailored to the specific needs and learning styles of that gender. Proponents argue that this setting can enhance academic performance and reduce distractions. In many countries, single-sex schools have a long history, with some dating back to the 19th century. They can be found at various educational levels, from primary to secondary. Critics, however, question their effectiveness and argue that coeducational settings better prepare students for real-world interactions.
