Physical education, often abbreviated to Phys. Ed. or PE, and sometimes informally referred to as gym class or simply just gym, is a subject taught in schools around the world. PE is taught during primary and secondary education and encourages psychomotor, cognitive, and effective learning through physical activity and movement exploration to promote health and physical fitness. When taught correctly and in a positive manner, children and teens can receive a storm of health benefits. These include reduced metabolic disease risk, improved cardiorespiratory fitness, and better mental health. In addition, PE classes can produce positive effects on students' behavior and academic performance. Research has shown that there is a positive correlation between brain development and exercising. Researchers in 2007 found a profound gain in English Arts standardized test scores among students who had 56 hours of physical education in a year, compared to those who had 28 hours of physical education a year.

A school is both the educational institution and building designed to provide learning spaces and learning environments for the teaching of students under the direction of teachers. Most countries have systems of formal education, which is sometimes compulsory. In these systems, students progress through a series of schools that can be built and operated by both government and private organization. The names for these schools vary by country but generally include primary school for young children and secondary school for teenagers who have completed primary education. An institution where higher education is taught is commonly called a university college or university.
