there is still a significant difference in the campus population on weekends. A good percentage of students attend parties at local clubs, many of which begin on Thursday night. Others travel to New York City or elsewhere on Long Island. There are several fraternities and sororities students can join at LIU Post. Athletics Long Island University competes in NCAA Division I as the LIU Sharks. Before 2019, LIU Post was a Division II school that is governed by the National Collegiate Athletic Association (NCAA), the Eastern College Athletic Conference (ECAC), the East Coast Conference (ECC), and the Northeast-10 Conference (NE-10). Prior to 2019, the two LIU campuses had separate athletics teams: C.W. Post had the LIU Post Pioneers and competed in Division II, and the other LIU campus in Brooklyn fielded the Division I Blackbirds. On July 1, 2019, the two campuses merged their two athletics teams into a single unit competing in Division I, henceforth known as the Sharks. Students may also participate in sports for leisure at the Pratt Recreation Center, where they can enjoy sports such as basketball, volleyball, racquetball, and swimming. There is also a fitness center for aerobic and cardiovascular workouts. The athletic fields and courts serve students wishing to play outdoor sports such as football, baseball, soccer, softball and tennis. The Pratt Center is also a venue for Nassau County and New York State high school basketball playoff games, both men's and women's, along with the Clark Center at the State University of New York College at Old Westbury.
