President Trump has chosen who he wants in his Cabinet. This powerful group of advisers include heads of the 15 executive departments. Each leader must be confirmed by the incoming Senate.

[ How long Cabinet confirmations take — and why past nominees failed]

Other top Trump administration officials and advisers do not require Senate confirmation.

Who Trump chooses to surround himself with greatly affects what his administration will accomplish. These top aides are just a slice of the 4,100 positions Trump’s transition team may need to find appointees for — people who will oversee day-to-day operations at the agencies that make up the executive branch of government.

[ Complete list: See how many key positions Trump has filled so far]

The following list includes descriptions of each of Trump’s Cabinet picks and their nomination timelines.

Jan. 20

Confirmed

Secretary of Education

Current head: John B. King Jr.

The bipartisan Every Student Succeeds Act, passed last year, shifted authority over public education from the federal government to the states. Trump's education head is likely to further reduce the federal role in public schools, and to push for an expansion of charter schools and vouchers for private and religious schools. Trump called the Common Core State Standards "a total disaster" during the campaign, and repeatedly pledged to get rid of them. But he won't be able to do that; it's up to states to decide which standards they use.

Nominee

AnnouncedBetsy DeVos

Chairman of American Federation for Children, a pro-school-voucher group

DeVos, a conservative activist and billionaire philanthropist, has pushed forcefully for private school voucher programs nationwide.

Secretary of Health and Human Services

Current head: Sylvia Mathews Burwell

During his campaign, Trump railed against the Affordable Care Act, the 2010 law that is providing insurance coverage to about 20 million Americans and is changing many other aspects of the U.S. health-care system, and the president-elect and congressional Republicans are sounding eager to repeal it as one of their first acts. HHS also runs two vast insurance programs: Medicaid for low-income people and Medicare for older Americans. Altogether, the $80 billion department budget funds 11 operating divisions, including the National Institutes of Health, the Centers for Disease Control and Prevention, the Food and Drug Administration and the agency that runs the nation’s welfare program, TANF.

Nominee

AnnouncedTom Price

Georgia congressman

Trump’s seriousness in carrying through on his “repeal” pledge is evident from his choice of health secretary: House Budget Committee Chairman Tom Price (R-Ga.), a champion of the House GOP’s efforts to abolish the law and replace it with free-market health policy ideas. Price also has wanted to convert Medicaid from an entitlement program to state block grants and to redefine Medicare by giving older Americans money to help buy private health plans.
