The National Collegiate Athletic Association (NCAA) is divided into three divisions, based roughly on school size. Each division is made up of several conferences for regional league play. Unless otherwise noted, changes in conference affiliation will occur on July 1 of the given year.

- While the Ivy League considers its athletic conference to have been established in 1954, the history of the athletic league can be traced back decades earlier:
- In 1901, the Eastern Intercollegiate Basketball League (EIBL) was formed by five schools that would later become part of the current Ivy League; the EIBL membership eventually became identical to that of the future all-sports league. The EIBL was directly absorbed into the all-sports Ivy League, which considers the EIBL to be part of its history.
- In 1945, the Ivy Group Agreement, which governed competition and policies among the Ivy schools in football, was signed by all eight schools that eventually formed the all-sports league.
- The official formation of the athletic Ivy League came in 1954, when the Ivy Group Agreement was extended to cover all sports.
- The Ivy League, by NCAA count, sponsors 28 NCAA-sanctioned sports. The Ivy League awards separate men's and women's fencing championships, while the NCAA considers fencing a single coeducational sport. Additionally, the Ivy League sponsors championships in the non-NCAA sports of men's rowing plus men's and women's squash.
- 8 full members, 6 football members

The current Big East maintains the pre-split history of the original conference in all sports that it sponsors.
