the delegates amended Zeta Beta Tau's constitution, ritual and internal procedures both in theory and in practice to eliminate sectarianism as a qualification for membership. Mergers The Zeta Beta Tau has merged with four other national Jewish fraternities: Phi Alpha, Kappa Nu, Phi Sigma Delta and Phi Epsilon Pi, with chapters and colonies at over 90 campus locations. In 1959, Phi Alpha merged into Phi Sigma Delta, and in 1961 Kappa Nu merged into Phi Epsilon Pi. In 1969–70, Phi Sigma Delta and Phi Epsilon Pi merged into Zeta Beta Tau. Zeta Beta Tau's official name is "A Brotherhood of Kappa Nu, Phi Alpha, Phi Epsilon Pi, Phi Sigma Delta and Zeta Beta Tau". Pledging abolished Zeta Beta Tau abolished the institution of pledging in 1989 as a way to combat and eliminate hazing, and replaced the pledging process with one in which new members are accepted as brothers upon receiving a bid to the fraternity. Zeta Beta Tau's decision to do away with pledging did not involve an associate membership process, however. Once a brother joins the fraternity he will receive all rights and responsibilities as the rest of the chapter, and shall be eligible for any position within the chapter regardless of how long he has been a brother. This decision was made in response to the Age of Liability, in which extensive research on hazing shed light on how the culture of subservient pledging led to a number of deaths nationwide. National philanthropies Children's Miracle Network Hospitals (CMNH), which raises funds for children's hospitals in North America, was chosen as an official philanthropy of the fraternity during a Supreme Council meeting in summer 2002. Chapters host Get on the Ball events in which people donate to CMNH to sign a large inflatable beach ball. The Zeta Beta Tau Foundation, a non-profit corporation exclusively committed to educational and charitable purposes that assist the Brothers of Zeta Beta Tau Fraternity, as another official philanthropic partner of the Fraternity. The foundation assists the fraternity by funding scholarships and academic and leadership programs to maximize their personal development and prepare them to be leaders of society. The scholarships and academic and leadership programs funded by the Foundation enhance the overall value of membership in Zeta Beta Tau Fraternity by complementing the collegiate educational experience. Jewish Women International has been the third official philanthropic partner of ZBT, since 2015. JWI is the
