"Co-Ed" refers to an educational system or institution that includes both male and female students. This term is commonly used in schools, colleges, and universities where boys and girls learn together in the same classes and participate in the same activities. The co-educational model promotes gender equality and social interaction among students of different genders. The concept of co-education emerged in the 19th century and has since become the standard in many countries. Co-ed institutions often provide a diverse environment that encourages collaboration and mutual respect, preparing students for real-world interactions in various settings, including workplaces and communities.
