Undergraduate study is the first level of higher education: the associate and bachelor’s degrees you enter from secondary school, before any degree is behind you. Graduate study is everything built on top of a completed bachelor’s degree: master’s degrees, doctoral degrees and professional degrees such as law and medicine, entered only once a bachelor’s is already earned. The federal data system that classifies every US student draws the line in exactly those terms — in the IPEDS glossary definitions, a graduate student is one who holds a bachelor’s degree or above and is taking courses at the postbaccalaureate level, while undergraduate students are those working at the level below it. Almost every practical difference between the two levels — admission requirements, how classes are taught, how long programs last, even how federal student loans treat you — follows from that single dividing line: a bachelor’s degree is the exit of the undergraduate level and the entry ticket to the graduate one. In the UK and most countries outside the US, the graduate level is called postgraduate; the two words name the same level.
Undergraduate vs graduate at a glance
| Undergraduate | Graduate | |
|---|---|---|
| Position | First level of higher education | Level above the bachelor’s degree |
| Degrees | Associate, bachelor’s | Master’s, doctoral (research and professional practice), post-baccalaureate certificates |
| Entry requirement | Secondary school completion (or equivalent) | A bachelor’s degree, usually in a related field |
| Typical duration | Associate ~2 years; bachelor’s ~4 years of full-time study | Master’s 1–2 years beyond the bachelor’s; doctorate several further years |
| Study style | Broad: general education plus a major; structured curriculum | Narrow and deep: one field, seminars, independent research or clinical practice |
| Who teaches / class size | Larger introductory lectures plus smaller classes | Small seminars, supervision, research groups |
| Federal loans (US) | Subsidised loans available to those with financial need; lower annual limits | Unsubsidised loans only; higher annual limit |
| UK term | Undergraduate | Postgraduate |
Durations in the table are the federal definitions’ own norms, set out below — individual programs vary around them in both directions.
What is an undergraduate student — and what degrees are undergraduate?
An undergraduate is a student who has not yet completed a bachelor’s degree and is enrolled at the first level: in a certificate or associate program below the bachelor’s, or in a bachelor’s program itself. The IPEDS degree definitions used across US higher education describe the two undergraduate degrees in time terms:
- An associate degree is an award that normally requires at least 2 but less than 4 years of full-time equivalent college work.
- A bachelor’s degree normally requires at least 4 but not more than 5 years of full-time equivalent college-level work.
Undergraduate study has a characteristic shape wherever you take it. The curriculum is deliberately broad — general education across several fields, then a chosen field in depth (the major, whose structure is set out in the comparison with minors elsewhere on this site) — because its job is to build a foundation rather than to complete a specialisation. Classes run from large first-year lectures down to smaller advanced ones. Students are typically admitted straight from secondary school, on school results, and — for the bachelor’s level — on the admissions tests compared in this site’s test guides. The degree totals a bachelor’s student must accumulate are covered in how many credits to graduate.
One wrinkle the definitions handle carefully: not everything below a master’s is undergraduate in the simple sense. Post-baccalaureate certificates — programs taken after a bachelor’s that do not reach master’s level — sit on the boundary; IPEDS counts some such students as graduate (they already hold a bachelor’s and study at postbaccalaureate level) and treats certain teacher-preparation certificate students as undergraduate despite the bachelor’s some of them hold. The line follows the level of the program and the student’s standing in it, not merely the person’s history — a detail that matters when loan and enrolment rules are applied.
What is a graduate student — and what degrees are graduate?
A graduate student holds a bachelor’s degree (or above) and is taking courses at the postbaccalaureate level — the definition carried in the federal IPEDS survey materials, which add that such students may or may not be enrolled in a formal graduate program. The graduate degrees, again in the federal definitions:
- A master’s degree requires the successful completion of a program of at least the full-time equivalent of 1 but not more than 2 academic years of work beyond the bachelor’s degree.
- A doctor’s degree is the highest award for graduate study. The federal classification splits it by purpose: research/scholarship doctorates (the PhD and its kin) built around original research and a dissertation, and professional practice doctorates — the degrees that qualify you to practise a profession, such as medicine (MD) and law (JD) — alongside a small “other” category.
That split explains the two very different experiences sold under the one word “graduate.” A research master’s or PhD is an apprenticeship in producing new knowledge: small seminars, close supervision, and a thesis or dissertation as the centrepiece. A professional degree is an apprenticeship in a practice: set curricula, clinical or field placements, and licensing examinations at the end. Both are graduate, both require a bachelor’s first, and confusing their shapes is the commonest planning error at this level — a student who wants to practise medicine and a student who wants to research it take different doctorates.
Admission is the other structural difference. Undergraduate admission judges readiness for a broad education, from school records. Graduate admission judges readiness for one specific field, from inside that field: a bachelor’s degree (often in a related subject, sometimes with prerequisite courses), undergraduate grades at a level the program sets, recommendations from people who taught you, a statement of purpose — and, for research programs, evidence you can do the work, up to a research proposal at doctoral level. Which undergraduate grades carry that weight is why the calculation in how to calculate GPA matters long after the bachelor’s itself is finished.
How teaching and study differ between the levels
The contrast students actually feel:
- Breadth vs depth. An undergraduate timetable mixes the major with general education and electives across unrelated fields. A graduate timetable is one field, at full depth — a master’s student in economics takes economics, methods for economics, and little else.
- Structure vs independence. Undergraduate programs prescribe most of the path: required courses in a set order. Graduate programs prescribe the territory and leave the route increasingly to the student — chosen seminars, self-directed reading, and at doctoral level a multi-year research project that the student defines and defends.
- Class format. Lectures dominate early undergraduate teaching; seminars, laboratories, studios and one-to-one supervision dominate graduate teaching. Cohorts are smaller, and classmates are colleagues in a field rather than a cross-section of a generation.
- Assessment. Undergraduate assessment is frequent and course-based. Graduate assessment leans on long projects, papers, comprehensive examinations and the thesis or dissertation — fewer, larger judgements.
None of this makes one level “harder” in a single sense. Undergraduate study is broader and more supervised; graduate study is narrower, more independent, and judged against the standards of a profession or a research field rather than a syllabus.
Cost and funding: where the levels genuinely diverge
Sticker prices vary too much by institution to generalise honestly — a graduate year at one university can cost less than an undergraduate year at another — so treat any guide that declares one level simply “more expensive” with suspicion. What does differ systematically is the funding machinery:
- Federal loans treat the levels differently by rule. Federal Student Aid makes Direct Subsidized Loans — where the government covers interest while you study — available only to undergraduates with financial need. Graduate students borrow Direct Unsubsidized Loans only, at a higher standard annual limit ($20,500 on the current Federal Student Aid table). The level you are enrolled at, not the price of the program, decides which loan rules apply to you.
- Graduate funding often comes attached to work or merit. Assistantships, fellowships and scholarships are a normal part of graduate — especially doctoral — funding in a way they are not at undergraduate level, where aid is dominated by need-based grants and loans. The terms differ program by program, which is why the only reliable graduate cost figure is the one a specific program publishes for itself, net of the funding it offers you.
- Time is a cost in opposite directions. An undergraduate degree is the long one (typically four years), a master’s the short one (one to two) — but it is bought after the four years, so the full path to a master’s is five to six years of study, and to a doctorate several more. Comparisons of “which level costs more” that ignore the sequence mislead by construction.
Undergraduate vs postgraduate: the same line, British wording
Outside the US, the graduate level is usually called postgraduate: an undergraduate degree is the first degree (bachelor’s), and postgraduate study — master’s and doctoral programs — follows it. The structure mirrors the American one almost exactly, including entry (a bachelor’s, often at a stated classification), duration (master’s commonly one to two years; doctorates several), and the research/professional split. American “graduate school” and British “postgraduate study” are translation equivalents, and application materials cross between them without conversion. One nearby word is not an equivalent: postdoctoral work comes after a doctorate, above both levels discussed here.
The institutional setting of the two levels — which kinds of institution teach which level — is the subject of college vs university: universities typically house both levels, colleges typically centre on the undergraduate one, with the familiar exceptions that article works through.
Is a bachelor’s degree undergraduate or graduate?
Undergraduate — always. The bachelor’s degree (BA, BS and their variants) is the senior degree of the undergraduate level, and holding one is precisely what qualifies a student to enter the graduate level. The same test settles the neighbouring questions: an associate degree is undergraduate (it sits below the bachelor’s); a master’s, PhD, MD or JD is graduate (each requires or builds beyond a bachelor’s — the JD and MD are professional practice doctorates in the federal classification); and a student in the final year of a bachelor’s program is still an undergraduate until the degree is conferred. “Graduate” as a level label describes where you study, not the ceremony: the person who has finished a bachelor’s is a graduate of it in the everyday sense, and becomes a graduate student only when enrolled at the level above.
Frequently asked questions
What is the difference between undergraduate and graduate degrees? An undergraduate degree (associate or bachelor’s) is a first degree, entered from secondary school and built broad — general education plus a major. A graduate degree (master’s or doctorate) is an advanced degree entered with a bachelor’s already completed, built narrow — one field, studied through seminars, supervised research or professional practice.
What is an undergraduate student? A student enrolled at the first level of higher education who has not yet completed a bachelor’s degree — including associate and certificate students below that level and bachelor’s students themselves.
Can you go straight from undergraduate to a PhD? In the US, commonly yes: many doctoral programs admit students directly from a bachelor’s degree — Stanford’s Earth and Planetary Sciences admission FAQ, for example, answers “Do I need a Master’s degree to apply to the Ph.D. program?” with “No” — with master’s-level work built into the doctoral program’s early years. Other systems and some programs require a master’s first. The admitting program’s own requirements decide — there is no general rule, and any guide stating one is overclaiming.
Is graduate school harder than undergraduate? It is different in kind: narrower, more independent, and assessed by fewer, larger pieces of work judged to a field’s standards. Students who thrived on breadth and structure can find the independence demanding; students who chafed under a prescribed curriculum often find graduate study easier to sustain. The level change is a change of method, not simply of difficulty.
What does postgraduate mean? The same as graduate, in UK and most non-US usage: study above the bachelor’s degree — master’s and doctoral programs. An undergraduate degree is a first degree; postgraduate study follows it.
Do graduate students get the same student loans as undergraduates? No. Under the federal rules published by Federal Student Aid, subsidised loans are undergraduate-only; graduate students use unsubsidised loans at a higher annual limit. Other aid — grants, assistantships, fellowships — follows its own program-level rules at both levels.
This article is general information about the two levels of US higher education and their UK equivalents, based on the federal IPEDS definitions and Federal Student Aid sources linked above and checked in November 2026. Program requirements, durations and funding are set by individual institutions; a program’s own published requirements are the final authority for admission to it.
