U.S. Department of Education
In February 2011, King was appointed by United States Secretary of Education Arne Duncan to serve on the U.S. Department of Education's Equity and Excellence Commission.
In January 2015, King became the Acting Deputy Secretary of Education (officially, the "Senior Advisor Delegated Duties of Deputy Secretary of Education"). In this position, he oversaw all policies and programs related to P-12 education, English learners, special education, and innovation. King also oversaw the agency's operations.
In the fall of 2015 when Arne Duncan announced that he would resign as Secretary of Education at the end of the year, U.S. President Barack Obama announced that King would succeed Duncan. At the White House press briefing discussing King's appointment, President Obama called King "the right man" to lead the Department of Education, and King replied that the President and Secretary Duncan had laid out "an ambitious agenda ... and I'm proud to be able to carry it forward." In choosing King to succeed Arne Duncan, The Washington Post stated that President Obama was "choosing continuity" and noted that King was pushing for the adoption of teacher evaluations, Common Core Standards and next generation student testing as the New York State Commissioner of Schools while the Obama administration was pushing for the adoption of similar reforms across the United States. Even if their education reform agendas are similar, Duncan pointed out that King's background (he has African-American and Puerto Rican heritage, and was orphaned at age 12) gave him a "set of experiences that I think will help to make him especially impactful."
On December 10, 2015, President Obama signed the Every Student Succeeds Act, the successor law to the No Child Left Behind Act. In remarks at the signing ceremony, the President said, "we are going to miss Arne Duncan a lot. Fortunately ... we also have a great replacement for Arne in Dr. John King, who is going to be doing outstanding work helping to implement this [new legislation]."
On January 1, 2016, King became Acting Secretary. On March 14, 2016, King was approved to be Secretary of Education by the United States Senate after a 49–40 vote. King was the second African-American, the second Latino and first Afro-Latino to serve as U.S. Secretary of Education. In September 2016, King travelled to six states to discuss education—visiting 11 cities and towns—for the Obama administration's final Back to School Bus tour.
King worked to advance the implementation of the Every Student Succeeds Act (ESSA), saying that it provides for a "well-rounded education" and that he is "among those who worry that the balance has shifted too much away from subjects outside of math and English that could be the spark to a child's interest and excitement, and are actually essential to success in reading, and are critical to a child's future."
In November 2016, the U.S. Department of Education released the final ESSA accountability rules, boosting state flexibility in key areas. "The final rules give states more time and flexibility to provide every student with a high-quality, well-rounded education while ensuring that states and districts keep the focus on improving outcomes and maintaining civil rights protections for all children, particularly those who need our support the most," King said in a statement.
King continued his efforts towards socioeconomic and racial integration by centering federal education policy on increasing student diversity and in December 2016 he announced a $12 million grant competition "that would give up to 20 school districts the opportunity to craft new roadmaps for increasing student diversity and get started on those plans. Districts could use the money to get ideas from their communities on the best ways to bolster school integration, do a data analysis of where they currently stand on integration, and more."
King has addressed school discipline directly—especially as it disproportionally affects students of color and students with disabilities—calling on states that continue to allow corporal punishment on students to cease and implement disciplinary measures that support students and reducing exclusionary disciplinary practices. King has played an integral role in coordinating inter-agency work on My Brother's Keeper including allowing as many as 12,000 prison inmates to apply for federal Pell grants to finance college classes, despite a 22-year congressional ban on providing financial aid to prisoners.
Preparing teachers to lead has been a top priority for King, allowing states to use Title II funds to aid in the development and preparation of teachers. For example, states can use Title II funds to:
Offer extra pay to teachers who teach in high needs subjects, or teach special populations, such as English-language learners.
Address working conditions in high-needs schools, or give teachers who work in them extra time to plan and collaborate.
Use federal teacher quality funds to support preparation programs at traditional universities, but also for alternative-preparation programs, and teacher residency programs.
Train principals, including giving them time to learn from each other.
King has also worked to increase and support teachers of color.
In addition to improving Pre-K-12 outcomes, King focused on college completion, noting that "far too many students start college but do not finish, with students of color and first-generation and low-income students dropping out at higher rates than their white or better-off peer." King introduced a number of initiatives and tools to increase college completion, crack down on predatory for-profit colleges, and minimize student debt.
