The final stage of formal learning which occurs after the completion of secondary education is known as higher education. It plays a vital role in providing trained and educated personnel. Higher education is broadly divided into general, professional and vocational. General higher education involves significant theoretical and abstract elements, with few applied aspects. Some of the areas of study within it are liberal arts, engineering and performing arts. Professional higher education focuses on the application of learning and seeks to diversify learning opportunities, stimulate innovation and enhance employability.
