IA was recognized by "Newsweek" magazine as the top public school in the nation in 2003, second in 2004, second in 2005, ninth in 2006, seventh in 2007, twelfth in 2008, second in 2009, 25th in 2010, 20th in 2011, 5th in 2012, 18th in 2013, 9th in 2014, and 8th in 2015. "Newsweek"'s standings were based on the number of IB (International Baccalaureate) or AP (Advanced Placement) tests that the school averaged per graduating senior. The IA's high rankings are due to the full diploma program being required of all students, meaning they each sit for at least 6 IB exams in May of their senior year. Each senior therefore takes at least six IB tests (in addition to the Theory of Knowledge course; Creativity, Action, & Service hours; and Extended Essay requirements), giving the school a high average number of IB tests.
