To be eligible to apply to the Extension School's degree programs, students must "earn [their] way in" by passing the Test of Critical Reading and Writing Skills as well as completing two or three designated admission classes with a B or better. In 2016, then-Dean
Huntington D. Lambert said that 32% of those who want to pursue an undergraduate degree (ALB) earn the grades necessary for admission, making admissions "very selective." If the admission requirements are met, acceptance is not guaranteed but very likely. About 85% of those admitted successfully earn their degree (ALB). ALB students may graduate
cum laude, but
magna and
summa cum laude are not offered. Extension students may earn the Dean's List Academic Achievement Award upon graduation based on a high GPA (at least 3.5 for ALB, 3.8 for ALM). Many courses are offered online, but a degree cannot be earned entirely online as students are required to take classes on campus before earning their degree. Students who wish to earn degrees must be formally admitted by the Admissions Committee. Admitted degree candidates are granted full privileges to Harvard's libraries, facilities, and student resources, as well as access to Harvard's museums and academic workshops. As of 2019–20, an undergraduate degree cost about $58,800, and a graduate degree cost about $28,400–$34,080. Of the over 30,000 students enrolled in the Extension School, 850 are admitted degree candidates for the Bachelor of Liberal Arts in Extension Studies (ALB) and 3,063 are admitted degree candidates for the Master of Liberal Arts in Extension Studies (ALM).
Bachelor of Liberal Arts (ALB) The undergraduate curriculum requires expository writing, quantitative reasoning, foreign language, moral reasoning, upper-level coursework, and an area of concentration. The expository writing class is known as a "gatekeeper course" as it will typically "determine whether [students] are prepared for the intensive and demanding curriculum." Once admitted as an ALB degree candidate, students must successfully complete 128 credits (Harvard courses are typically 4 credits each) and maintain good academic standing to meet graduation requirements. Upon admission into the ALB program, students may petition to transfer up to a maximum of 64 credits from other accredited post-secondary institutions, but at least 64 credits must be completed at Harvard. Students select one of three "areas of concentration" which are humanities, science, and social sciences. ALB degree candidates are also required to complete a minimum of 16 on-campus-only credits at Harvard; students must also complete a minimum of 12 writing-intensive credits and earn a minimum of 52 credits in courses that are taught by Harvard instructors. In addition to a concentration, degree candidates have the option to pursue one of twenty "fields of study" (similar to majors). In order to successfully complete a field of study, students must earn a B− or higher in 32 Harvard credits in one field, and maintain a B average in the field. Students may also complement their degree with up to two minors.
Undergraduate admissions Undergraduate degree programs require pre-admission courses as well as a formal application process. Students must also hold a "high school diploma or its equivalent [which] must have been earned at least five years prior to enrolling in any ALB degree-applicable courses." Students applying for degree candidacy must complete three 4-credit liberal arts courses at Harvard with at least a B grade in each, and maintain a minimum 3.0 cumulative
GPA. One of these three pre-admission courses must be EXPO E-25. To enroll in this course, students must either pass a placement test, which measures critical reading and writing skills, or enroll in EXPO E-15 (a course that acts as a precursor to EXPO E-25). Students failing to earn at least a B in a class can retake it once. Those who meet all these criteria are then eligible to apply for admission into the school's undergraduate degree programs.
Graduate programs (ALM) The
Master of Liberal Arts (ALM) encompasses over 20 fields of study across the liberal arts and professional disciplines. Subjects range from traditional humanities and social sciences (such as Anthropology, English, History, and Psychology) to specialized professional and STEM programs (including Biotechnology, Data Science, Cybersecurity, Management, and Sustainability). All ALM candidates must complete 12 courses—48 credit hours—to earn their degree. Most fields of study require students to complete either an in-depth thesis or a capstone project, which is typically crafted under the direction of an instructor or faculty member holding a teaching appointment in the Harvard Faculty of Arts and Sciences.
Graduate admissions Application to a graduate degree program requires an accredited four-year bachelor's degree (or foreign equivalent), passing the Test of Critical Reading and Writing Skills, the completion of two or three designated pre-admission courses with grades of B or higher, and a cumulative grade-point average of 3.0. One of the pre-admission courses must be the "proseminar" course for the intended area of study, which is akin to a traditional research methods course. Some disciplines have additional specified pre-admission coursework, while others have specific coursework that is required before submitting a master's thesis proposal (biology and psychology students must take a specific graduate statistics course). In addition, several programs require supplemental application materials; for instance, Creative Writing and Literature ALM candidates must submit original manuscripts. Students who meet these criteria are then eligible to submit an application for admission into the graduate degree programs (ALM). A student who fails to earn a grade of B after twice enrolling in the proseminar course—often considered a "gatekeeper" course—will be denied admission indefinitely.
Degree naming convention The formal titles of the Harvard University undergraduate and graduate degrees are
Baccalaureus in Artibus Liberalibus (ALB) and
Magister in Artibus Liberalibus (ALM). On a diploma, the degree is officially conferred by Harvard University as "Bachelor of Liberal Arts in Extension Studies" or "Master of Liberal Arts in Extension Studies." The specific area of focus (e.g., Management) is designated as the "Field of Study." Over the years, there have been efforts by faculty and students to remove the phrase "in Extension Studies" from the school's degrees. In 2009 and 2010, a faculty committee proposed renaming the school and dropping the phrase, but the proposal was rejected due to concerns that the new degree titles would be too similar to those offered by Harvard College and the Graduate School of Arts and Sciences. Since then, students have continued to advocate for degree names that reflect their specific fields of study, organizing rallies in 2016, 2022, and 2023. Although former Dean Huntington D. Lambert publicly agreed with the students' concerns in 2019, the official degree titles remain unchanged; however, students' official transcripts do reflect their specific areas of academic concentration or fields of study.
Privileges and demographics Students who graduate with a degree from the Extension School become part of the Harvard Alumni Association. Extension students have dedicated study spaces, conferences rooms, and access to the dining hall in
Lehman Hall.
Alpha Sigma Lambda, the national honor society for nontraditional students, has a Harvard chapter. There is a student government body for the Harvard Extension School which participates in the
Harvard Graduate Council. Admitted degree candidates have access to many of the same student privileges of other Harvard alumni, such as access to athletic facilities, libraries, and museums. The Extension School primarily serves working professionals and adult learners. As of 2026, the average age of the student body is 32, with students representing all 50 U.S. states and over 110 countries. The student body is generally divided between individuals taking single courses for professional enrichment and those formally pursuing a degree. Historically, the student body has included a wide range of educational backgrounds. In 2000, the school enrolled over 14,000 students; at that time, 75% of enrolled students already held a bachelor's degree and more than 1,700 were Harvard employees using the Tuition Assistance Program. While the school occasionally allowed high-school-aged minors to enroll during the early 2000s, it has since implemented strict age requirements to focus exclusively on adult learners. The Extension School now requires that a high school diploma or its equivalent is earned at least five years prior to enrolling in any courses applicable to its undergraduate degree. The Extension School enrolls thousands of international students each year. While international degree candidates must meet the same on-campus residency requirements as domestic students, the Extension School itself does not issue F-1 student visas for its part-time fall and spring semesters. Instead, international students typically fulfill these residency requirements by obtaining short-term F-1 visas through Harvard Summer School to attend intensive on-campus sessions. ==Student life==
