The widely held assumption that Congress gets nothing done doesn't exactly fit this year. For one thing, the government didn't shut down and there were no defaults on the national debt. Here are eight other legislative matters Congress addressed in 2015 -- and a few they couldn't agree on.
  1. Trillion-Dollar Government Funding Bill
    Right before they split for the holidays, lawmakers passed a trillion-dollar spending bill that will keep the government open until the end of next September. The measure also beefed up cybersecurity and renewed a health care program for Sept. 11 first responders. It also made changes to the visa waiver program so people who have traveled to Iraq, Iran, Syria and Sudan in the past five years will face greater scrutiny if they wish to enter the U.S.
  2. Tax Extenders
    Paired with the government spending bill was a measure containing hundreds of billions of dollars in tax breaks. Year after year, Congress has had to extend dozens of tax breaks that expire. In this measure, lawmakers made permanent the most popular tax breaks, such as the $1,000 child tax credit, the earned income tax credit for low- and moderate-income workers, and the research and development tax credit.
  3. Two-Year Budget Agreement
    Right before Boehner left office, he managed to reach a two-year budget deal with the White House and other congressional leaders. The agreement suspends the debt ceiling through March 2017 and increases spending by $80 billion over the next two years — an increase that's split evenly between defense and domestic programs.
  4. No Child Left Behind Rewrite
    Congress easily passed legislation to rewrite the 2002 No Child Left Behind Act. Federally mandated math and reading tests will continue, but the new law cedes greater authority to states, rather than the federal government, to figure out how to use the test results in evaluating schools.
  5. Five-Year Transportation Bill
    Congress passed its first long-term bill in a decade to fund roads, bridges and mass transit systems. The measure does not raise the gas tax, currently at 18.4 cents per gallon, but found other sources of funding — such as changing customs fees and dipping into funds from the Federal Reserve.
  6. Ended The NSA's Bulk Surveillance Program
    Lawmakers passed the USA Freedom Act, which ended the government's bulk collection of phone records. Passage of the measure came after Republican senator and presidential candidate Rand Paul of Kentucky forced a two-day shutdown of the bulk collection program.
  7. Trade Promotion Authority
    Congress approved a measure to give the president expedited authority to enter a trade deal with 11 other Pacific Rim countries. Attention now turns to the Trans-Pacific Partnership agreement, which Congress is expected to consider next year — possibly after the election is over.
  8. Medicare Reform
    Known as the "Doc Fix" bill, this measure permanently ended automatic Medicare payment cuts to physicians. Under a law from the late 1990s, Medicare payments to doctors would be cut to keep the program's budget in check. Since then, Congress had failed every year to figure out a long-term solution to the problem.
  9. But there are still some unresolved issues ...
    Not because lawmakers think they're unimportant but because partisan divisions on these ideological issues are so deep, they can't find common ground. Congress seems happy to take these issues to the voters in 2016.
  10. Guns
    After a spate of gun-related tragedies in 2015, Democrats vowed to push for gun control legislation, such as measures to expand background checks and prohibit individuals whose names are on terrorist watch lists from purchasing firearms. Both measures failed in the Senate in 2015, as in past years.
  11. Immigration
    The Senate managed to pass a comprehensive immigration overhaul package in 2013, but attempts to move the legislation through the House failed. Efforts to resurrect immigration legislation have since languished.
  12. Tax Reform
    After the midterm election, corporate tax reform was seen as a possible area Republicans and Democrats could work together on. But at his year-end news conference, McConnell expressed pessimism about getting any tax reform accomplished with a Democrat in the White House, saying that any tax changes need to be revenue-neutral and he doubted the president would go for that.
