Most Devoted to Public Service: Delta Sigma Theta

The largest Greek letter sorority for black women, Delta Sigma Theta was founded in 1913 at Howard University—only two months later, the founding sisters participated in the Women's Suffrage March in Washington D.C. (Thousands of members are pictured above retracing their route in the capital on March 3, 2013.) Over the last century, DST has grown to more than 1,000 chapters, and operates on a "five point" program designed to promote economic and educational development, international and political awareness and involvement, and physical and mental health. Sorority programs and initiatives include Delta Academy to enrich education for young teens, and Mary Help of the Sick Mission Hospital, which provides prenatal and maternity care to women in Kenya. Delta Sigma Theta also established the Delta Research and Educational Foundation (DREF) as a public charity supporting scholastic achievement, public service programs, and research initiatives focused on African-American women. DST sisters have included Shirley Chisholm, Barbara Jordan, Barbara Watson, Patricia Roberts Harris, and Ruby Dee Davis.

Oldest: Alpha Delta Pi

Founded in 1851 as the Adelphean Society at Wesleyan College in Macon, Georgia, the country's first secret society for women changed its name to Alpha Delta Phi in 1905. That year, it expanded to Salem College, in Winston-Salem, North Carolina; it later changed its name in 1913 to Alpha Delta Pi. The sorority has now grown to include 155 active chapters in the U.S. and Canada.

Best Sorority House: Phi Mu

Each semester, 68 women live in the house, whose highlights include a baby grand piano, marble floors, an elevator, and a chandelier that originally hung in New York's Waldorf-Astoria Hotel.

Boasting more than 155,000 members, Alpha Omicron Pi also has more active chapters (190) than any other sorority in the country.

Coolest Symbols: Sigma Sigma Sigma

While Sigma Sigma Sigma's official symbol is a sailboat, initiated members wear a badge adopted in 1903 featuring a golden triangle, a gold Sigma in each corner, and a skull and crossbones in the center. The symbolism of the skull and crossbones is only revealed to Tri Sigma members after initiation—although it's not a leap to guess, as the sorority's motto is Faithful Until Death.

Best Charity Partnership: Delta Delta Delta

Delta Delta Delta has supported St. Jude Children's Research Hospital since 1999 (with support for children's cancer charities since the 1970s). Tri Delt has raised more than $45 million for the hospital, and in July 2014 the sorority announced a fundraising commitment of $60 million over 10 years—the largest fundraising commitment in St. Jude's history.

Best Leadership Program: Kappa Kappa Gamma

Kappa runs a leadership and self-esteem program for middle-school-aged girls called GIRLS Academy—the first of its kind among Greek organizations—designed to combat objectification of women and promote empowerment. During half-day retreats, girls discuss personal challenges, participate in community service, and write about dreams they hope to accomplish.

Most Philanthropic: Delta Gamma

With the motto, "Do Good," Delta Gamma—founded in 1873 in Oxford, Mississippi—is inextricably linked with philanthropy. DG's foundation gives annual grants and benefits Service for Sight, which is devoted to protecting the gift of sight, and funds four schools founded by Delta Gamma for blind or visually-impaired children. Anchor Splash, its annual swimming competition fundraiser, is a social highlight at many colleges. Last year, DG sisters donated 227,171 service hours, and over the past 10 years, the Delta Gamma Foundation has donated more than $4.3 million. Delta Gamma also offers a Sisters Helping Sisters scholarship program, which has given more than $2.2 million to help collegiate women with student loan debt.
