Academic divisions
Purdue offers both undergraduate and graduate programs in over 211 major areas of study, and is well known for its competitive engineering curricula. The university has also been integral in America's history of aviation, having established the first college credit offered in flight training; the first four-year bachelor's degree in aviation; and the first university airport: Purdue University Airport. Purdue's aviation technology and aeronautical engineering programs remain among the most competitive aviation-specific programs in the world. In the mid-20th century, Purdue's aviation program expanded to encompass advanced spaceflight technology, giving rise to Purdue's nicknames Cradle of Astronauts and Mother of Astronauts. Twenty-seven Purdue graduates have become astronauts, including Gus Grissom, one of the original Mercury Seven astronauts; Neil Armstrong, who was the first person to walk on the Moon; and Eugene Cernan, who was the last person to walk on the Moon.
The English department at Purdue launched the first Online Writing Lab (OWL), in 1994. Many colleges and universities use the Purdue OWL website as an academic writing reference source for proper word usage, punctuation, grammar, and style. Professors criticized the partnership, begun in 2020, between OWL and the company Chegg, which provides AI-generated "homework help" that some consider to be plagiarism.
Purdue is organized into 10 colleges and schools. In 2010, the College of Health and Human Sciences was formed, through combining existing academic units, including the School of Nursing, the School of Health Sciences, the College of Consumer and Family Sciences, and non-humanities majors psychology and hearing and speech pathology from the College of Liberal Arts.
The university's College of Agriculture supports the university's charge as a land-grant university for the study of agriculture throughout the state.
The College of Education offers undergraduate degrees in elementary education, social studies education, science education and special education, and graduate degrees in these and many other specialty areas of education.
The Purdue University College of Engineering was established in 1874 with programs in Civil and Mechanical Engineering. The college now offers BS, MS, and PhD degrees in more than a dozen disciplines. Purdue's engineering program has also educated 27 American astronauts, including Neil Armstrong and Eugene Cernan, who were the first and last astronauts to have walked on the Moon, respectively, and Gus Grissom, a member of the Mercury Seven. In 2025, the department announced an all-Boilermaker team to crew a commercial spaceflight mission flown by Virgin Galactic. Many of Purdue's engineering disciplines are recognized as top-ten programs in the U.S. The college as a whole is currently ranked 4th in the U.S. of all doctorate-granting engineering schools by U.S. News & World Report.
The university's Exploratory Studies program supports undergraduate students who enter the university without having a declared major. It was founded as a pilot program in 1995 and made a permanent program in 1999.
The College of Health and Human Sciences was established in 2010 and is the newest college. It offers BS, MS and PhD degrees in all 9 of its academic units.
Purdue's College of Liberal Arts contains the arts, social sciences and humanities programs at the university. Liberal arts courses have been taught at Purdue since its founding in 1874. The School of Science, Education, and Humanities was formed in 1953. In 1963, the School of Humanities, Social Sciences, and Education was established, although Bachelor of Arts degrees had begun to be conferred as early as 1959. In 1989, the School of Liberal Arts was created to encompass Purdue's arts, humanities, and social sciences programs, while education programs were split off into the newly formed School of Education. The School of Liberal Arts was renamed the College of Liberal Arts in 2005.
The Daniels School of Business offers management courses and programs at the undergraduate, master's, and doctoral levels.
The university's College of Pharmacy was established in 1884 and is the 3rd oldest state-funded school of pharmacy in the United States.
The Purdue Polytechnic Institute, formerly known as the College of Technology, offers bachelor's, master's and PhD degrees in a wide range of technology-related disciplines. With over 30,000 living alumni, it is one of the largest technology schools in the United States. In addition to the main school in West Lafayette, Purdue Polytechnic operates nine satellite campuses in Anderson, Columbus, Indianapolis, Kokomo, Lafayette, New Albany, Richmond, Vincennes, and South Bend. These locations offer certificate, associate, and/or bachelor's degrees, some of which are ABET-accredited technical degrees.
The Polytechnic Institute also maintains two high school campuses in Indianapolis that focus on science, technology, engineering, and mathematics and feature hands-on project-based learning. While having also maintained a high school campus in South Bend, Polytechnic Institute announced the closure of the South Bend campus with the end of the 2025-2026 school year.
The university's College of Science houses the university's science departments: Biological Sciences; Chemistry; Computer Science; Earth, Atmospheric, & Planetary Sciences; Mathematics; Physics & Astronomy; and Statistics. The science courses offered by the college account for about one-fourth of Purdue's one million student credit hours.
The College of Veterinary Medicine is accredited by the AVMA.
Purdue's John Martinson Honors College supports an honors program for undergraduate students at the university. The Honors College's mission is to "create and foster well-rounded, well-educated global leaders," through their four pillars of interdisciplinary academics, undergraduate research, community and global engagement, and leadership development.
Through Purdue Online, the administrative unit charged with planning and enabling the effort, Purdue has a growing online presence, in addition to Purdue Global, offering more than 200 programs through the university's four accredited institutions (Purdue West Lafayette, Purdue Northwest and Purdue Fort Wayne in Indiana and Purdue Global) including master's degree programs. Purdue Online, the unified online education initiative approved by Purdue President Mitch Daniels and the Purdue Board of Trustees in December 2018, is intended to radically expand these offerings by developing a "coordinated, unified system-wide portfolio of online course and degree offerings for students of all types." Students manage their Purdue University admin account using the BrightSpace Purdue Student Portal.
