Arne Duncan

In January 2022, Duncan expressed interest in running for Mayor of Chicago in the 2023 Chicago mayoral election. In March 2022, he announced that he had decided not to run.

In 2021, Duncan endorsed Deborah Kerr, his former high school teacher, in the non-partisan race for Superintendent of Public Instruction of Wisconsin. Though Duncan has no direct ties to Wisconsin, he said "I was lucky to have Dr. Kerr as a high school teacher, her care for students is evident...Wisconsin needs a strong leader in this role and I am thrilled this state has the chance to have her as their next state superintendent." Alongside State Senator Lena Taylor of Milwaukee, Duncan was one of very few prominent Democrats to endorse Kerr in the race.

His 2018 book, How Schools Work: An Inside Account of Failure and Success From One of the Nation’s Longest-Serving Secretaries of Education, details his work pushing forward the Common Core standard and discusses examples of students falling far below the education level needed to pursue college that instigated this policy push.

In 2017, he was appointed a distinguished senior fellow at the University of Chicago's Harris School of Public Policy.

In March 2016, Duncan announced he would join the Palo Alto-based education group Emerson Collective as a managing partner.

On October 2, 2015, Duncan announced he would be stepping down at the close of 2015, to be succeeded by John King Jr. The media stated his tenure had been marked by a "willingness to plunge head-on into the heated debate about the government's role in education."

On July 4, 2014, the National Education Association, the largest teacher's union in the United States, passed a resolution of "no confidence" in Duncan's leadership of the Department of Education and asked for his resignation.

On July 13, 2014, the American Federation of Teachers approved a resolution calling for Education Secretary Arne Duncan to resign if he does not improve under a plan to be implemented by President Barack Obama. The "improvement plan" would require that Duncan enact the equity and funding recommendations of the Equity Commission's "Each and Every Child" report; revise the No Child Left Behind and Race To The Top "test-and-punish" system of accountability to a "support-and-improve" structure; and "promote rather than question" teachers and school staff.

On May 11, 2014, Duncan was a member of the 2014 USA Basketball 3x3 Men's Championship Team. The team of Duncan, Jitim Young, Thomas Darrow and Craig Moore qualified to represent the United States in Moscow, Russia in the 24-country 2014 FIBA 3x3 World Championship from June 5–8. Duncan's schedule did not permit him to attend, but the team finished in 9th place in the 24-team tournament.

Addressing a group of school superintendents in late 2013, Arne Duncan stated that he found it "fascinating" that some of the opposition to the Common Core State Standards Initiative came from "white suburban moms who—all of a sudden—their child isn't as brilliant as they thought they were, and their school isn't as good as they thought they were." He was widely criticized for framing the controversy in racial terms.

In March 2011, Duncan said 82 percent of the nation's public schools could be failing by the following year under the standards of the No Child Left Behind law. The projection amounted to a startling spike from previous data, which showed that 37 percent of schools were on track to miss targets set by the law. "Four out of five schools in America would not meet their goals under [No Child Left Behind] by next year", Duncan said in his statement.

Opinions vary on Duncan's success as CEO. In 2009, Kathleen Kingsbury of Time noted improved test scores and described Duncan as a consensus builder. Jitu Brown, Rico Gustein, and Pauline Lipman wrote a 2009 article published by Rethinking Education which argued that notion of improvements having been made to the school system were largely a myth, and which expressed concern over the closure of neighborhood schools and their replacement by charter schools, and what they described as schools' militarization.

Duncan was appointed U.S. Secretary of Education by President Barack Obama and confirmed by the Senate on January 20, 2009. One of Duncan's initiatives as secretary has been a $4 billion Race to the Top competition. It asks states to vie for federal education dollars by submitting proposals that include reforms such as expanding charter schools and judging teachers partly on how well their students do on standardized tests.

Mayor Richard M. Daley appointed Duncan to serve as Chief Executive Officer of Chicago Public Schools on June 26, 2001. As CEO, Duncan was in charge of the implementation of the Renaissance 2010 initiative and served as the public spokesman for it.

After graduating, Duncan played professional basketball for several years until 1991. In 1992, childhood friend and investment banker John W. Rogers, Jr., appointed Duncan director of the Ariel Education Initiative, a program mentoring children at one of the city's worst-performing elementary schools and then assisting them as they proceeded further in the education system. After the school closed in 1996, Duncan and Rogers were instrumental in re-opening it as a charter school, Ariel Community Academy. In 1999, Duncan was appointed deputy chief of staff to Chicago Public Schools CEO Paul Vallas.

Duncan attended the University of Chicago Laboratory Schools and later Harvard College, where he played on the basketball team and graduated magna cum laude in 1987 with a bachelor's degree in sociology. His senior thesis, for which he took a year's leave to do research in the Kenwood neighborhood, was entitled "The values, aspirations and opportunities of the urban underclass".

While at Harvard, Duncan co-captained the varsity basketball team and was named a first team Academic All-American. From 1987 to 1991, Duncan played professional basketball, mostly in Australia, with teams including Melbourne's Eastside Spectres, of Australia's National Basketball League. Duncan also participated in the 2012, 2013, 2014, and 2020 NBA All-Star Weekend Celebrity Games. Comedian Kevin Hart conceded the 2014 MVP of the celebrity game to Duncan (20 points, 11 rebounds, 6 assists). The 20 points are a Celebrity Game high.
