In 2012, the university raised $1.035 billion, becoming the first school to raise more than a billion dollars in a year. Stanford follows a quarter system with the Autumn quarter usually starting in late September and the Spring Quarter ending in early June. The full-time, four-year undergraduate program has an arts and sciences focus with high graduate student coexistence. Stanford is accredited by the Western Association of Schools and Colleges. Full-time undergraduate tuition was $42,690 for 2013–2014. Stanford's admission process is need-blind for US citizens and permanent residents; while it is not need-blind for international students, 64% are on need-based aid, with an average aid package of $31,411. In 2012–13, the university awarded $126 million in need-based financial aid to 3,485 students, with an average aid package of $40,460. Eighty percent of students receive some form of financial aid. Stanford has a no-loan policy. For undergraduates admitted in 2015, Stanford waives tuition, room, and board for most families with incomes below $65,000, and most families with incomes below $125,000 are not required to pay tuition; those with incomes up to $150,000 may have tuition significantly reduced. 17% of students receive Pell Grants, a common measure of low-income students at a college. As of 2016 the Office of the Vice Provost and Dean of Research oversaw eighteen independent laboratories, centers, and institutes. Other Stanford-affiliated institutions include the SLAC National Accelerator Laboratory (originally the Stanford Linear Accelerator Center), the Stanford Research Institute (an independent institution which originated at the university), the Hoover Institution on War, Revolution and Peace (a major public policy think tank that attracts visiting scholars from around the world) and the Hasso Plattner Institute of Design (a multidisciplinary design school in cooperation with the Hasso Plattner Institute of University of Potsdam that integrates product design, engineering, and business management education). Stanford is home to the Martin Luther King Jr. Research and Education Institute which grew out of and still contains the Martin Luther King Jr. Papers Project, a collaboration with the King Center to publish the King papers held by the King Center. It also runs the John S. Knight Fellowship for Professional Journalists and the Center for Ocean Solutions, which brings together marine science and policy to address challenges facing the ocean. Together with UC Berkeley and UC San Francisco, Stanford is part of the Biohub, a new medical science research center founded in 2016 by a $600 million commitment from Facebook CEO and founder Mark Zuckerberg and pediatrician Priscilla Chan.
