Students can typically participate in a variety of team sports. There may be a single team for a sport or teams with different skills levels, from intramural teams that play against each other within the school to junior varsity and varsity teams that play against other schools. Teams are often separated by sex, although some schools may field coed teams for certain sports. Athletic programs may include football, basketball, baseball, softball, hockey, swimming, field hockey, lacrosse, diving, gymnastics, volleyball and wrestling. In addition, schools often have cheerleading and pep squads to support the teams and rally the crowds at games.
