Tertiary education is the stage of formal education that follows secondary schooling, but the term does not map perfectly onto higher education, post-secondary education, college, or university in every country. For international comparison, the clearest reference point is UNESCO’s International Standard Classification of Education (ISCED): tertiary education covers ISCED levels 5 through 8, from short-cycle tertiary programs through doctoral study. Education can still be post-secondary without being tertiary, because ISCED 4 is classified as post-secondary non-tertiary education. [UNESCO UIS]
This distinction matters when comparing countries. A Canadian college diploma, a British further-education qualification, a Danish Academy Profession degree, a Japanese junior-college award, and an Australian VET qualification may all sit after secondary school, yet they do not automatically occupy the same education level. The name of the institution is not enough. Program level, entry requirements, learning outcomes, qualification awarded, and access to further study determine where a program sits.
What Tertiary Education Means Internationally
The ISCED system allows national education structures to be compared without assuming that every country uses the same school names or degree titles. The dividing line appears between ISCED 4 and ISCED 5. ISCED 4 remains outside tertiary education, while ISCED 5 begins the tertiary sequence.
| ISCED Level | International Classification | Typical Role | Tertiary? |
|---|---|---|---|
| ISCED 4 | Post-secondary non-tertiary education | Builds on upper secondary education; may prepare learners for employment or entry to tertiary study | No |
| ISCED 5 | Short-cycle tertiary education | Often practical or occupation-specific; may lead directly to work or onward tertiary study | Yes |
| ISCED 6 | Bachelor’s or equivalent level | First-degree academic or professional study | Yes |
| ISCED 7 | Master’s or equivalent level | Advanced academic or professional specialization; some long first degrees may also sit here | Yes |
| ISCED 8 | Doctoral or equivalent level | Advanced study centered on original research | Yes |
OECD reporting follows the same basic sequence. Its 2026 definitions describe short-cycle tertiary education as programs that commonly provide professional knowledge and occupational skills and may also provide progression into bachelor’s- or master’s-level study. Bachelor’s programs are typically three to four years when entered directly after upper secondary education, while master’s-level study contains more advanced specialization. [OECD]
The Boundary to Remember
Education after secondary school is not automatically tertiary education. UNESCO defines ISCED 4 as post-secondary non-tertiary study because its content remains below the complexity associated with tertiary programs. [UNESCO UIS]
Tertiary Education vs Higher Education vs Post-Secondary Education
The three expressions overlap, but they should not be treated as universal synonyms. Tertiary education has the clearest international statistical boundary. Post-secondary education is often broader. Higher education depends more heavily on national terminology and law.
| Term | General Meaning | Can Include Vocational Study? | ISCED 4 Included? | Universities Included? |
|---|---|---|---|---|
| Tertiary education | Internationally comparable education at ISCED 5–8 | Yes | No | Yes |
| Higher education | Advanced education defined by each national system; often overlaps strongly with tertiary education | Yes, where nationally classified as higher education | Not necessarily | Yes |
| Post-secondary education | Education taken after secondary schooling | Yes | Can include it | Yes |
The United States illustrates the broad use of postsecondary. The U.S. Department of Education uses the term for education options after high school and discusses colleges, degree programs, and career-oriented study within that space. [U.S. Department of Education]
Canada also uses post-secondary broadly. Federal guidance identifies universities, colleges, vocational schools, and Quebec CEGEPs as post-secondary institutions, while provinces and territories hold major responsibility for education. [Canada]
Short-Cycle Tertiary Education Is a Separate Level
International discussions of higher education often jump directly from secondary school to a bachelor’s degree. That misses ISCED 5. Short-cycle tertiary education is not an unfinished bachelor’s program. It is a recognized tertiary level in its own right.
Programs at this level are often practical, occupation-specific, and shorter than first-degree study. Some are designed mainly for direct labor-market entry. Others allow graduates to receive credit or move into a longer tertiary program. UNESCO also allows academic tertiary programs below bachelor’s level to be classified at ISCED 5 when they meet the relevant criteria. [UNESCO UIS]
Vocational Does Not Automatically Mean Non-Tertiary
A vocational program can sit below tertiary level, at short-cycle tertiary level, or within professionally oriented bachelor’s and master’s education. The word vocational describes orientation; it does not, by itself, determine the international education level.
Institution Type and Education Level Are Different Questions
A common comparison error is to classify education only by the institution’s name. A college can award tertiary degrees in one country and mainly sub-degree qualifications in another. A vocational institution can offer tertiary study. A university may offer short-cycle or professionally oriented programs alongside traditional degrees.
- A university does not imply that every program it offers occupies the same ISCED level.
- A college is not a globally standardized institution type.
- A polytechnic may deliver diploma, short-cycle tertiary, bachelor’s, or postgraduate study depending on the country.
- A vocational school may operate below tertiary level, inside tertiary education, or across both.
- A qualification called a diploma cannot be assigned an international level from its title alone.
Britain provides a useful example. Further Education (FE) generally covers study after secondary education that is not part of an undergraduate or graduate degree, yet FE colleges can also deliver higher-education qualifications. Provider category and qualification level therefore overlap without being identical. [UK Government]
How Tertiary and Post-Secondary Terminology Changes by Country
National terminology reflects each country’s institutions, qualification system, and history. The table below compares the common language used across the 19 education systems covered by EducationByCountry.org. It describes the broad structure rather than claiming that similarly named qualifications are academically identical.
| Country | Common Term or Structure | Main Post-Secondary / Tertiary Institutions | Distinctive Feature |
|---|---|---|---|
| Australia | Higher education, VET, tertiary education | Universities, non-university higher education providers, TAFE institutes, registered training organizations | Higher education and VET form separate but connected sectors with credit and pathway options |
| Canada | Post-secondary education | Universities, colleges, institutes, vocational schools, CEGEPs | Structures and terminology vary by province and territory |
| China | Higher education | Academic higher education institutions, undergraduate vocational institutions, associate-level vocational institutions | Academic and vocational tertiary provision operate on a very large scale |
| Denmark | Higher education | Universities, university colleges, business academies, artistic institutions, maritime institutions | Academy Profession programs provide a clear short-cycle professional route |
| Estonia | Higher education | Universities and professional higher education institutions | Academic and professionally oriented tertiary routes coexist |
| Finland | Higher education | Universities and universities of applied sciences | Universities emphasize research; applied-sciences institutions emphasize professional higher education |
| France | Higher education | Universities, Grandes Écoles, engineering schools, business schools, specialist institutions | University and selective institutional routes coexist with shorter higher-education programs |
| Germany | Higher education | Universities, universities of applied sciences, art, film, and music colleges | Applied-sciences institutions place greater emphasis on professionally oriented study |
| Indonesia | Higher education | Universities, institutes, polytechnics, colleges, academies and other recognized providers | Academic, vocational, and professional routes operate within higher education |
| Japan | Higher education | Universities, junior colleges, professional and vocational universities, colleges of technology, specialized training colleges | Several recognized non-university routes sit beside four-year university study |
| Netherlands | Tertiary / higher education | Research universities and universities of applied sciences | The system distinguishes WO academic study from HBO higher professional education |
| New Zealand | Tertiary education | Universities, wānanga, polytechnics, private training establishments and work-based providers | The national use of tertiary is broader than university education alone |
| Singapore | Post-secondary education | Junior colleges, polytechnics, ITE, arts institutions, autonomous universities | The post-secondary umbrella includes both pre-university and tertiary routes |
| South Korea | Higher education | Four-year universities, associate-degree colleges, graduate schools and specialized institutions | Two- and three-year associate-degree pathways sit beside four-year degree programs |
| Sweden | Higher education | Universities and university colleges | Higher education is organized through first-, second-, and third-cycle study |
| Switzerland | Higher / tertiary education | Universities, federal institutes of technology, universities of applied sciences, universities of teacher education | Academic higher education sits within a wider tertiary level that also has strong professional routes |
| Türkiye | Higher education | Universities and vocational schools within the higher-education system | Associate, bachelor’s, master’s, and doctoral programs form the main degree sequence |
| United Kingdom | Further Education and Higher Education | Universities, higher-education providers, FE colleges and specialist providers | FE and HE are separate concepts even though some FE colleges deliver HE qualifications |
| United States | Postsecondary / higher education | Universities, four-year colleges, community colleges and career-oriented institutions | Postsecondary often functions as the broadest term for education after high school |
Australia: VET and Higher Education Are Connected but Distinct
Australia separates Vocational Education and Training (VET) from higher education institutionally, while both operate within the wider tertiary landscape. TAFE institutes and registered training organizations deliver VET. Universities and non-university higher education providers deliver higher education, including associate degrees, bachelor’s degrees, graduate certificates, graduate diplomas, master’s degrees, and doctorates. Some TAFEs also operate in higher education. [Study Australia]
The boundary is becoming more permeable through credit recognition and progression routes. Australia also formally established the Australian Tertiary Education Commission in April 2026, with part of its role centered on closer coordination between higher education and VET. [Australian Department of Education]
New Zealand Uses “Tertiary” in a Particularly Broad National Sense
New Zealand offers one of the clearest examples of why tertiary education should not be translated as “university education.” Its tertiary sector includes universities, wānanga, vocational providers, private training establishments, and work-based training. Wānanga can award certificates, diplomas, and degrees, with some provision extending to doctoral level. [New Zealand Ministry]
The country’s vocational tertiary arrangements are also changing. Reforms that took effect on January 1, 2026 began a transition toward regional polytechnics, Industry Skills Boards, private training establishments, and wānanga taking defined roles in vocational and work-based learning. The transition is scheduled to continue through 2027. [New Zealand Ministry]
The Netherlands Separates Academic and Professional Higher Education
Dutch tertiary education has two main branches. WO refers to scientific or research-oriented university education, while HBO refers to higher professional education delivered mainly by universities of applied sciences. Both sit inside tertiary higher education, and both use bachelor’s and master’s degrees, although their orientation and normal program structure differ. [Netherlands Government]
This distinction shows why professional should not be read as “below tertiary.” A professionally oriented bachelor’s degree remains tertiary education even when it has a more applied curriculum than a research-university degree.
Finland and Germany Show Different Forms of Applied Higher Education
Finland divides higher education between universities and universities of applied sciences. Universities combine teaching and research and can award doctorates. Universities of applied sciences concentrate more strongly on professionally oriented higher education and applied research and development. [Finnish National Agency]
Germany also has universities and universities of applied sciences, alongside art, film, and music colleges. Universities of applied sciences are especially associated with practice-oriented academic study. The institutional distinction is therefore about academic orientation and mission, not a simple division between tertiary and non-tertiary education. [DAAD]
Denmark Gives Short-Cycle Higher Education a Visible Place
Denmark’s higher-education system includes universities, university colleges, business academies, artistic institutions, and maritime institutions. Its Academy Profession (AP) programs are especially relevant to international comparisons: they are short-cycle, professionally oriented programs, commonly around two to two-and-a-half years, and can provide progression into a professional bachelor’s top-up route. [Study in Denmark]
Japan Has Several Higher-Education Routes Beyond Universities
Japan’s official higher-education structure includes four-year universities but also junior colleges, professional and vocational universities, colleges of technology, and specialized training colleges. Junior colleges commonly award associate degrees after two or three years. Specialized training colleges can award diplomas and advanced diplomas, while professional and vocational universities award professional bachelor’s degrees. [Study in Japan]
South Korea likewise includes four-year universities, graduate schools, and two- or three-year associate-degree programs. This is another case where higher education extends below bachelor’s level. [Study in Korea]
Singapore Shows Why Post-Secondary and Tertiary Are Not Identical
Singapore’s official post-secondary education category includes several institution types with different purposes. Junior colleges and Millennia Institute prepare students for qualifications such as A Levels or the International Baccalaureate before university. Polytechnics provide diploma-level, practice-based education. The Institute of Technical Education offers technical and work-study routes, while autonomous universities deliver degree education. [Singapore MOE]
So, a student can be in post-secondary education without yet being in tertiary education. Singapore makes that distinction easy to see because pre-university junior colleges sit within the post-secondary sector.
Türkiye Includes Associate Degrees Within Higher Education
Türkiye’s higher-education system includes associate, bachelor’s, master’s, and doctoral study under the supervision of the Council of Higher Education. Associate-degree programs normally take two years, while bachelor’s programs commonly take four years, with longer programs in fields such as medicine. Vocational schools operate inside the higher-education system rather than forming a wholly separate post-secondary layer. [CoHE]
Degree Names Do Not Have Universal International Levels
Words such as certificate, diploma, associate degree, professional bachelor, and advanced diploma are useful inside national systems, but their names alone cannot establish equivalence across borders.
- Certificate: may describe secondary, post-secondary non-tertiary, tertiary, continuing, or professional study depending on the system.
- Diploma: may identify a short-cycle tertiary award in one country and a different level elsewhere.
- Associate degree: usually represents short undergraduate study, but its international classification depends on program design and national mapping.
- Bachelor’s degree: commonly corresponds to ISCED 6, though entry, duration, and professional orientation differ.
- Master’s degree: commonly corresponds to ISCED 7; some long first degrees can also be classified at this level when their content and complexity meet the criteria.
- Doctorate: generally corresponds to ISCED 8 and requires advanced study centered on original research.
This is why international credential comparison examines more than the award title. It considers the recognized education level, duration, admission standard, curriculum, learning outcomes, institutional authority, and progression rights attached to the qualification.
Common Routes From Secondary School Into Tertiary Education
Tertiary systems are not single ladders. Students can reach advanced study through several routes, and a country may support several of them at once.
| Route | Typical Sequence | What It Shows |
|---|---|---|
| Direct degree route | Upper secondary → Bachelor’s → Master’s → Doctorate | The familiar academic progression |
| Short-cycle route | Upper secondary → ISCED 5 → Employment or Bachelor’s-level progression | Tertiary education can begin below bachelor’s level |
| Post-secondary bridge | Upper secondary → ISCED 4 → Tertiary education | Post-secondary study can prepare students for tertiary entry without itself being tertiary |
| Applied professional route | Upper secondary → Applied / professional tertiary program → Employment or postgraduate study | Professional education can operate at tertiary level |
| Vocational progression route | Vocational education → Work experience or further qualification → Tertiary study | Vocational and tertiary paths can connect rather than remain separate |
Academic, Professional, and Vocational Tertiary Education
Academic Tertiary Education
Academic tertiary education places more weight on theoretical knowledge, disciplinary study, and research methods. Research universities commonly occupy this space, although academic and professional content can coexist within the same institution.
Professional Tertiary Education
Professional tertiary education prepares students for defined occupations or applied fields while still operating at tertiary level. Universities of applied sciences, professional bachelor’s programs, teacher education institutions, nursing programs, engineering programs, and similar routes may fit here depending on national classification.
Vocational Tertiary Education
Vocational tertiary programs usually place stronger emphasis on occupation-specific skills, practical instruction, work placements, or direct labor-market preparation. Short-cycle tertiary education is often vocationally oriented, but vocational education also exists at secondary and post-secondary non-tertiary levels. Context determines the level.
OECD’s 2026 education analysis notes that vocational and tertiary pathways should not be treated as mutually exclusive categories. Applied and work-based learning can appear within tertiary education, while short-cycle vocationally oriented programs can create progression into higher tertiary levels. [OECD]
Tertiary Attainment and Tertiary Enrollment Measure Different Things
International education statistics use several terms that sound similar but measure different populations. Confusing them can produce misleading country comparisons.
| Measure | What It Describes | What It Does Not Automatically Mean |
|---|---|---|
| Tertiary enrollment | Students enrolled in programs classified at tertiary levels | It does not mean all students attend universities |
| Tertiary attainment | People whose highest completed education is tertiary | It is not the same as current enrollment |
| University enrollment | Students enrolled at institutions counted as universities | It may exclude colleges, polytechnics, or other tertiary providers |
| Higher-education enrollment | Students covered by a country’s national higher-education definition | Its national boundary may not match another country’s terminology exactly |
| International students | Students identified as international under the relevant data definition | It is not automatically identical to foreign citizenship or all cross-border learners |
Tertiary attainment normally refers to completed qualifications, not attendance. A person who entered university but did not complete a tertiary qualification is not automatically counted as tertiary-educated in attainment statistics. Likewise, a person whose highest completed qualification is ISCED 5 may be counted as tertiary-educated even without a bachelor’s degree.
Tertiary enrollment is also broader than university enrollment. In systems where short-cycle colleges, professional institutes, applied-sciences institutions, or other providers deliver ISCED 5–8 programs, tertiary enrollment can include students outside traditional universities.
Why Tertiary Enrollment Rates Need Careful Country Comparison
A higher tertiary enrollment figure does not, by itself, prove that one education system offers broader access or stronger outcomes than another. The measured population and system design matter.
- Program length: longer programs keep students enrolled for more years and can affect headcounts.
- Short-cycle inclusion: systems with large ISCED 5 sectors may enroll many tertiary students outside bachelor’s programs.
- International mobility: countries receiving many students from abroad can have enrollment totals that exceed what domestic demographics alone suggest.
- Part-time study: headcount statistics and full-time-equivalent measures describe different volumes of study.
- Adult participation: tertiary systems with mature learners and flexible study can have different age patterns from systems dominated by recent school graduates.
- Population denominator: gross enrollment ratios and age-specific participation measures should not be treated as interchangeable.
Comparisons are strongest when countries are measured with the same data definition, same education levels, same reference year, and compatible population measures. Otherwise, an apparent difference may reflect classification rather than student participation.
National Qualification Levels Should Not Be Matched to ISCED by Number Alone
Many countries maintain numbered national qualification levels. Europe also uses a common reference structure for comparing national qualifications. These systems serve a different purpose from ISCED. A qualification labeled Level 6 nationally or regionally is therefore not automatically the same thing as ISCED 6.
ISCED classifies education programs and attainment for international statistics. National qualification levels describe qualifications according to learning outcomes and national rules. The numbers may sometimes appear to align, but that visual similarity should never substitute for the official mapping used by the country and international data provider.
Common Misunderstandings About Tertiary Education
| Claim | Accurate Interpretation |
|---|---|
| “Tertiary education means university.” | No. ISCED 5–8 can include non-university institutions and short-cycle programs. |
| “Anything after high school is tertiary.” | No. ISCED 4 is post-secondary but explicitly non-tertiary. |
| “Vocational education is always below higher education.” | No. Vocational and professional programs can exist at tertiary levels. |
| “College means the same thing everywhere.” | No. College can mean very different institution types across the United States, Canada, the United Kingdom, Japan, and other systems. |
| “A two-year program cannot be tertiary.” | No. Short-cycle tertiary programs commonly operate below bachelor’s level. |
| “A diploma has one international level.” | No. Diploma is a national award name, not a universal ISCED level. |
| “Higher education and tertiary education are always identical.” | No. They overlap strongly, but national usage can define higher education differently. |
What Makes Two Tertiary Programs Comparable
Country comparisons become more accurate when they move beyond institution names and compare the characteristics of the program itself. The strongest comparison checks several dimensions together:
- ISCED classification or the officially mapped international education level.
- Entry requirement, including the prior qualification needed for admission.
- Qualification awarded after successful completion.
- Normal study duration and full-time equivalent workload.
- Academic, professional, or vocational orientation.
- Progression rights into bachelor’s, master’s, doctoral, or other advanced study.
- Institutional authority to award the qualification.
- Learning outcomes rather than the English translation of the award name.
A two-year qualification from one country and a two-year qualification from another can therefore belong to different education levels. Conversely, programs with different names may occupy comparable tertiary levels when their official classification, learning outcomes, and progression rights align.
Tertiary Education in 2026 Is Less Linear Than the Traditional University Ladder
The classic sequence of bachelor’s, master’s, and doctorate remains central to higher education, but national systems now make much greater use of short-cycle qualifications, applied degrees, credit transfer, work-based learning, professional higher education, and vocational-to-degree progression. The result is a set of routes rather than one universal ladder.
OECD’s 2026 reporting reflects this reality by keeping vocational orientation and tertiary level as separate characteristics: a program can be both vocationally oriented and tertiary. Australia is working toward closer coordination between VET and higher education, while New Zealand’s 2026 vocational changes are reorganizing how polytechnic and work-based tertiary training is delivered. These developments reinforce a basic statistical principle: education level, institution type, and program orientation must be identified separately. [OECD]
For international comparison, the most reliable baseline remains simple: ISCED 5–8 is tertiary education; ISCED 4 is post-secondary non-tertiary education. National terms such as higher education, college, further education, polytechnic, professional education, and post-secondary education should then be interpreted within each country’s own system rather than assumed to carry the same meaning everywhere.
