NCAA Division I Basketball Conferences: A Comprehensive Overview
College basketball, played by student-athletes at universities and colleges, is governed by organizations such as the National Collegiate Athletic Association (NCAA), the National Association of Intercollegiate Athletics (NAIA), the United States Collegiate Athletic Association (USCAA), the National Junior College Athletic Association (NJCAA), and the National Christian College Athletic Association (NCCAA). These organizations are often divided into divisions based on scholarship availability. While institutions can compete independently, most join conferences, which significantly influence scheduling, rivalries, and access to tournaments. In the United States, the NCAA is the primary governing body for college sports, including basketball.
The Evolution of Conference Affiliation
Traditionally, geographic location and institutional compatibility were the primary factors determining conference affiliation. Proximity fostered local rivalries and reduced travel costs, while shared values and academic standards created cohesive groups. For example, as of 2025, all full members of the West Coast Conference are Christian colleges and universities located in the Pacific Time Zone.
However, since the 1990s, the landscape of NCAA Division I conference membership has shifted. Geographic proximity has become less critical, driven by schools seeking lucrative media rights deals and competitive football programs. The Big Ten Conference, initially composed of Midwestern institutions, has expanded to include members in New Jersey, Maryland, Pennsylvania and even the Pacific Time Zone. Similarly, the Atlantic Coast Conference (ACC), once confined to the Atlantic Coast, now includes members in Massachusetts, New York, Pennsylvania, Kentucky, and Indiana.
These shifts often create a domino effect, where smaller conferences struggle to maintain competitiveness as they lose members to larger, more stable conferences. The smallest NCAA Division I conferences sometimes recruit Division II teams and help those institutions transition to Division I, in order to replace teams they have lost.
Independent Teams
Teams are not required to join conferences and may play as independents instead. Chicago State is the most recent independent basketball team in Division I of the NCAA, having competed as an independent for two seasons before joining the Northeast Conference in 2024. However, independent teams face challenges in scheduling, especially later in the season when most teams prioritize conference games.

Conference Tournaments and NCAA Tournament Bids
Each conference receives an automatic bid to the NCAA tournament, which generates significant revenue for participating teams. Most games between conference opponents take place in the latter part of the season. While there are various rankings of teams throughout the entire NCAA, there are also conference standings based on the results of games against conference opponents. Once the conference schedule is complete, the conference stages a tournament that includes some or all of its teams. A notable exception to the regular-season standings being used for seeding in the conference tournament were the 2023 and 2024 Western Athletic Conference (WAC) men's and women's tournaments. Regular-season conference standings determined qualification for the tournaments, but seeding was based on a formulaic ranking of the strength of the qualifiers, including their performances against non-conference opponents. In most cases, the winner of the conference tournament receives an automatic bid to the NCAA tournament.
However, teams transitioning to Division I are ineligible for the NCAA tournament. Under rules revised in 2025, the transition period from Division II to Division I generally takes three years and may be longer, if the team is coming from a different affiliation. Therefore, if such a team wins a conference tournament, the conference will use an alternative method to designate the team that receives its automatic bid.
A Brief History of College Basketball
The history of basketball can be traced back to a YMCA International Training School, known today as Springfield College, located in Springfield, Massachusetts. The sport was created by physical education teacher James Naismith, who in the winter of 1891 was given the task of creating a game that would keep track athletes in shape and that would prevent them from getting hurt. The date of the first formal basketball game played at the Springfield YMCA Training School under Naismith's rules is generally given as December 21, 1891. Along with this during the history and rise of the college game of basketball many issues arose. These issues were known as "civil wars" in college basketball, according to Kurt Edward Kemper. At first all colleges were considered as equal competitors because there were no divisions or conferences which caused smaller schools to protest against this. The first recorded game between two college teams occurred on November 22, 1894, when the Drexel Institute of Art, Science and Industry (now known as Drexel University) faced Temple College (now known as Temple University). Drexel won the game, which was played under rules allowing nine players per side, among many other variations from modern basketball, 26-1.
The early development of college basketball also saw the rise of tournaments. The AAU national championship tournament (first played in 1898) often featured collegiate teams playing against non-college teams. Four colleges won the AAU tournament championship: Utah (1916), NYU (1920), Butler (1924) and Washburn (1925). The first known tournament featuring exclusively college teams was the 1904 Summer Olympics, where basketball was a demonstration sport, and a collegiate championship tournament was held. The Olympic title was won by Hiram College. In March 1908, a two-game "championship series" was organized between the University of Chicago and Penn, with games played in Philadelphia and Bartlett, Illinois. In March 1922, the 1922 National Intercollegiate Basketball Tournament was held in Indianapolis - the first stand-alone post-season tournament exclusively for college teams. The champions of six major conferences participated: Pacific Coast Conference, Southern Intercollegiate Athletic Association, Western Pennsylvania League, Illinois Intercollegiate Athletic Conference, Michigan Intercollegiate Athletic Association and Indiana Intercollegiate Athletic Association.
In 1939, another national tournament was implemented by the National Collegiate Athletic Association (NCAA). The location of the NCAA tournament varied from year to year, and it soon used multiple locations each year, so more fans could see games without traveling to New York. Although the NIT was created earlier and was more prestigious than the NCAA for many years, it ultimately lost popularity and status to the NCAA Tournament. In 1950, following a double win by the 1949-50 CCNY Beavers men's basketball team (when the NIT comprised 12 and the NCAA 8 teams), the NCAA ruled that no team could compete in both tournaments, and effectively indicated that a team eligible for the NCAA tournament should play in it. Not long afterward, assisted by the 1951 scandals based in New York City, the NCAA tournament had become more prestigious than before, with conference champions and the majority of top-ranked teams competing there. The NCAA tournament eventually overtook the NIT by 1960. Through the 1960s and 1970s, with UCLA leading the way as winner of ten NCAA Tournament championships, a shift in power to teams from the west amplified the shift of attention away from the New York City-based NIT. When the NCAA tournament expanded its field of teams from 25 to 32 in 1975, to 48 in 1980, to 64 in 1985, and to 68 teams in 2011, interest in the NCAA tournament increased again and again, as it comprised more and more teams, soon including all of the strongest ones. In 2011, the NCAA field expanded to 68 teams and the last 8 teams playing for four spots making the field into 64, which is called the first round and so on. In 2016, the field did not expand, but the round numbers changed again. The first four games containing the last 8 teams is now referred to as the first four. Consequently, the first round does not start until the first four games are out of the way and the field is narrowed to 64 teams. So after the first four games the first round starts instead of that being the second round.

In 2020, for the first time in the NCAA's history, the tournament had to be canceled due to fears of the COVID-19 pandemic. The cancellation of the tournament, due to the COVID-19 pandemic, led to a lot of uncertainty for the coaches, players, and NCAA as a whole. Many people were very disappointed and had wished it was just delayed, rather than completely being cancelled. Unfortunately, this pandemic really effected the seniors on the teams, considering their last season just got abruptly taken from them. The NCAA did consider granting waivers to the student athletes who participated in winter sports (including basketball) so that they could regain eligibility for the 2021 season. In 2021, the tournament was able to take place, and the teams were so ready to be back. Baylor was the Men's 2021 NCAA Champions. In 2022, Kansas won the tournament, defeating North Carolina in the championship. For the women's competition, the 2021 champions were Stanford, who defeated Arizona in a very close game. In 2022, the women's NCAA champions was South Carolina, defeating UConn in the championship.
The National Invitation Tournament (NIT)
The National Invitation Tournament (NIT) is an annual men's college basketball tournament operated by the National Collegiate Athletic Association (NCAA). Since 2023, all rounds of the tournament are played at various sites across the country which are selected annually. From its founding in 1938 to 2022, the semifinals and finals were always played at Madison Square Garden (MSG) in New York City. A second, much more recent "NIT" tournament is played in November and known as the NIT Season Tip-Off. Formerly the "Preseason NIT" (and still sometimes referred to as such colloquially), it was founded in 1985. Unlike the postseason NIT, its final rounds are played at Madison Square Garden.
Racial Integration in College Basketball
Racial integration of all-white collegiate sports teams was high on the regional agenda in the 1950s and 1960s. These issues included inequality, racism, and the alumni demand for the top players needed to win high-profile games. The Atlantic Coast Conference (ACC) took the lead. "College basketball data allow for direct comparisons of the racial differences in the marginal revenues generated by players" (Brown and Jewell 1995). First they started to schedule integrated teams from the North. The wake-up call came in 1966 when Don Haskins's Texas Western College team with five black starters defeated the all-white University of Kentucky team to win the NCAA national basketball championship. This happened at a time when there weren't any black varsity basketball players in either the Southeastern Conference or the Southwest Conference. society.
In 1969, for the first time, the NCAA Council did not permit participation by American college basketball players in the Maccabiah Games. The Maccabiah Games are an international multi-sport event held in Israel, open to all Jewish athletes from around the world, and to all Israeli citizens regardless of their religion. Basketball was different, however. In 1969-against the wishes of the NCAA-Yale University Jewish center Jack Langer played for Team United States at the 1969 Maccabiah Games in Israel. He did so with the approval of Yale President Kingman Brewster, the university said it would not stop Langer from "what we feel is a matter of religious freedom," and all Ivy League presidents fully endorsed Yale's stand. Thereafter, Yale played Langer in basketball games the following season. A special assistant to the President of Yale, Henry Chauncey Jr., said: "There is no question that Jack Langer will continue to play basketball. in regard to the "Langer Case". The Harvard Crimson called the probation "not only unjust, but intolerable", and urged the Ivy League to withdraw from the NCAA. Harvard track and field captain Ed Nosal and two other Harvard athletes, sympathetic to Langer and Yale and disdainful of the absurdity of the NCAA rule, protested at the 1970 NCAA Indoor Track and Field Championships by standing on the awards stand wearing blue Yale jerseys. In February 1970, Representative Robert N. The Yale case, involving basketball player Jack Langer, is tragic. It shows that the NCAA is willing to use any weapon in its continuing power struggle with the Amateur Athletic Union. It shows that the NCAA does not care if it hurts member institutions or individual athletes in the process. It shows once again that the NCAA is …
Early Basketball Rules
The original rules for basketball were very different from today's modern rules of the sport, including the use of eight players per side. A player cannot run with the ball. The ball must be held by the hands. No shouldering, holding, pushing, striking, or tripping in any way of an opponent is allowed. The first infringement of this rule by any person shall count as a foul; the second shall disqualify him until the next goal is made or, if there was evident intent to injure the person, for the whole of the game. A goal shall be made when the ball is thrown or batted from the grounds into the basket and stays there, providing those defending the goal do not touch or disturb the goal. When the ball goes out of bounds, it shall be thrown into the field and played by …
