Universities in Greece form one part of constitutionally-recognized institutions with degree awarding powers. According to Greece's Constitution, higher education institutions (HEIs) include universities, polytechnics, some specialist HEIs, and formerly technological educational institutes (TEIs). In Greece, universities are private and public-owned and funded having state-accredited university title and authorization of university degree awarding powers at level 6 (first cycle qualification, bachelor's level) under the Bologna Process and the National Qualification Framework of Greece which is officially named Hellenic Qualification Framework (HQF; Greek: ).
The State University System of Greece operates on the term system of two semesters per academic year, has the national curriculum (national education system) set forth by the Ministry of Education of Greece ().
Higher education institutions.
Public Higher Education Institutions' (HEIs; Greek: ) undergraduate programmes in Greece are government funded and have free education without any payment of tuition fee. About one-fourth of postgraduate programmes are offered without tuition and 30% of students can be entitled to attend tuition-free postgraduate programmes after they are assessed on individual criteria. ;ref name="Law 4485/2017 Government Gazette 114/Α/4-8-2017" ; ;/ref ; The Hellenic Qualification Framework (HQF) sets out the different levels of education qualifications and the requirements for each of these and is linked to the European Qualifications Framework (EQF), and thus to other qualifications frameworks across the European Union.
The regulated framework for Greece higher education qualifications, which is tied to the HQF, covers degree-levels qualifications of Greece degree-awarding bodies and is linked to the Qualifications Framework in the European Higher Education Area (QF-EHEA) established by the Bologna process where Greece is a full member since 1999. Joining to the Bologna process Greece began education reforms in order to get higher education meeting the common European Union standards. Now the process is implemented in all higher education institutions. The programmes of EHEA are set at three levels of study which are usually referred to as the three cycle system.
First (entry level), a four-year cycle of study at EQF level 6 to attain a bachelor's degree or its equivalent (Greek: ; transliterated to Ptychio in dhimotiki from 1976–present; or defunct ; Ptychion in polytonic, katharevousa up until 1976). A second cycle of study follows at EQF level 7 lasting one or two years to attain a master's degree (, also known as: δίπλωμα μεταπτυχιακών σπουδών (Δ.Μ.Σ.), 'diploma of postgraduate studies') or equivalent, which is distinguished from a postgraduate diploma, typically having 120 ECTS, as opposed to a full master's degree which usually has 180. The third cycle of study at EQF level 8, lasting three years, awards a doctoral degree () or equivalent.
With the law 5094/2024, Government Gazette 39/A/13-3-2024, the establishment and operation of private ("non-state")Higher Education Institutions (HEIs) was permitted. A fully-recognized private Higher Education Institution must obtain a Higher Education Accreditation by the National (Hellenic) Authority for Higher Education (HAHE) and an official establishment and operating license by the Greek Ministry of Education. Such HEIs are yet to be accredited and established. 
The Open Courses are undergraduate and graduate courses taught in Greek Public Higher Education Institutions (HEIs) that are free of cost, freely accessible and freely available to any person over the Internet (online). It operated by the Greek Academic Network (GUnet), also known as Greek Universities Network (GUnet), a member of the Open Education Global (OE Global).
With the paragraph 10 of article 34 of the Law 2725/15-6-1999, Government Gazette 121/A/17-6-1999, high school graduate athletes from 17 to 30-year-old who hold specific sport achievements are admitted without entrance Panhellenic Examinations to anyone of their choice undergraduate department of the public Higher Education Institutions of Greece.
Universities and technical universities.
Universities () can grant one or more of bachelor's, master's, integrated master's and doctorate degrees. The undergraduate programme of study for most disciplines is four years with awarded qualification in line with the Bologna process legal equivalent to a bachelor's degree, 240 ECTS, at level 6 of Greece's National Qualification Framework (NQF), European Qualifications Framework (EQF), or International Standard Classification of Education (ISCED).
Technical universities, also known as polytechnics (Greek: ), grant degrees at the integrated master's level (which is divided into a 3-year undergraduate degree qualification and a 2-year postgraduate one), master's, and doctorate level. In specific disciplines, only the undergraduate programme is five years with awarded qualification (Greek: "", Latinised version: Diploma) that is legally equivalent to an integrated master's degree, which is often the standard route to chartered status for a regulated profession in Greece. The integrated master's degree is a specialized degree corresponding to a master-level degree which has integrated part of an undergraduate degree. It is also called an undergraduate master's degree, where instead of studying for two separate degrees, a student will study for a single, longer programme. A student can also be awarded the 3-year undergraduate qualification (180 ECTS), instead of pursuing the masters should he wishes to. The most common integrated master's is in engineering, for example a Dipl.-Eng or Dip.Arch.Eng/M.Arch, and also others along with some programmes in the fine arts.
In medical schools, six years of studying are required to earn a bachelor's degree.
In addition to earning an academic degree in specific disciplines only, state license is required to practice independently within the country of Greece, and some disciplines have further licensing requirements to bestow a recognized appellation (chartered accountant, attorney at law, doctor of medicine, etc.). Diploma is a prerequisite for registration as a chartered professional, so it is also known as professional degree. The use of specific professional titles for some professions is legally regulated. For a regulated profession, access to professional practice requires holding a particular specific degree (e.g. professional degree), taken special exams that are required to earn state practice credential such as it must pass the National Council Licensure Examination, a period of practical training under supervision similar to internship, and/or registration with a professional body.
International programmes.
With the law 4692/2020, Part II, Chapter III, from Article 82 to Article 95, the Greek Higher Education Institutions (HEIs) can provide first cycle programmes of studies in a language other than Greek. 
Among the Greek universities offer English-taught full-time programmes with tuition are: 
University rankings in Greece.
An external evaluation of all Greek universities was conducted by the Hellenic Quality Assurance and Accreditation Agency (HQA).
The following universities rank in at least one of the four major global rankings:
Technological educational institutes.
Technological educational institutes (TEIs; Greek: ) was a classification of Greek public HEIs (government subsidised) from 1983 to 2019, also called "Technological Educational Institutes" (TEIs) "of Higher Education", "Technological Institutes", "Institutes of Technology", "Technological Universities", and rarely "Technical Colleges".
The undergraduate degree programmes, which by default included a one-time, 960 hours-long internship term known as "practical training semester", consisted of four years and 240 ECTS-credits, previously a ;templatestyles src="Fraction/styles.css" / ;3+1⁄2-year (law 1404/24-11-1983, 1983–1995) and 210 ECTS, in line with the Bologna Process equivalent to a Level 6 ISCED bachelor's degree; the postgraduate degree programmes were ;templatestyles src="Fraction/styles.css" / ;1+1⁄2 years full-time or three years part-time with 90 credits and awarded qualification equivalent to a master's degree, ISCED 7. All TEIs in Greece were reformed between 2013 and 2019 and their departments have been incorporated into existing Higher Education Institutions.
Former HEIs.
HEIs are defunct due to either closure or merger. Such events include:
The progressive education reforms of the "ATHENA" reform plan restructured higher education from 2013 to 2019.
Mergers of TEIs in 2018–2019:
Specialist HEIs.
Military HEIs offer undergraduate programs which lead to a bachelor's degree-level in military studies, have been called Higher Military Education Institutions (ASEI; Greek: ). Since 2010, they have offered studies for master's degree-level specialized diplomas and doctoral degrees. They conduct officer training for the Hellenic Armed Forces and have been considered national defense universities since 1961. Students at all Military Forces Academies are referred to as cadets and receive a monthly stipend during education. All cadets reside on campus and receive meals in dining halls. Cadets are not referred to as freshmen, sophomores, juniors, or seniors but instead fourth class, third class, second class, and first class cadets, respectively. All foreign cadets are commissioned into the military forces of their home countries. Upon graduation, all cadets become commissioned as second lieutenants, entry-level rank, and are employed in the Hellenic Armed Forces for a compulsory minimum term of duty service. 
Non-HEIs.
After the law 5094/13-3-2024 published on Government Gazette 39/A/13-3-2024 permits in Greece the establishment and operation of private Higher Education Institutions (HEIs). Before the law 5094/13-3-2024 it was prohibited the operation of private Higher Education Institutions (HEIs). 
In Greece, there are also the private colleges which are not considered universities and are not recognized as HEIs or degree-awarding bodies by the Greek government. The Post-secondary Education Centres (Greek: ) accredited by the Ministry of Education to which the Private Colleges belong, also they can be called Post-secondary Colleges (non-tertiary), they are bodies of non-typical education ("") known as non-formal education bodies.
According to the State Constitution of Greece, "education at university level must be provided exclusively by institutions which are fully self-governed public law legal bodies".
This prohibits private companies from operating post-secondary education that provides studies at Level 6 and higher on the Greek Qualifications Framework. However, it does not prohibit colleges from collaborating in Greece with foreign universities to offer undergraduate and postgraduate programmes.
The Panhellenic Association of Recognised Colleges (Greek: ) is the representative body for the Greece located recognised private colleges. All the private colleges located in Greece are for-profit. Generally, any individual who wants to found a college in Greece must obtain a Higher Education Accreditation by the National (Hellenic) Authority for Higher Education (HAHE) and a license by the Ministry of Education, but has no obligation to become a participatory member of HCA.
The vast majority of colleges are offering programmes of study under franchise or validation agreements with universities established in other European Union countries, primarily in the UK, leading to degrees which are awarded directly by those universities. The monitoring of those agreements as well as of additional provisions for the operation of colleges is carried out by the Ministry of Education and confirmed by Parliament by a 2008 law. Amendments were passed in 2010, ;ref name="Law 3848/2010 Government Gazette 71/A/19-5-2010" ; ;/ref ; 2012, ;ref name="Law 4093/2012 Government Gazette 222/A/12-11-2012" ; ;/ref ; 2013, and 2014. They are also monitored by the respective educational authorities of the countries of the partnered universities, for example QAA and NARIC for a British university.
One example of a college which neither operating as a franchise nor was validated through arrangements in the UK was the University of Indianapolis – Athens Campus, which ceased operations in July 2014. By contrast, this college was wholly owned and operated by its home campus, and is therefore accredited by the same agency which accredits the home campus. Consequently, students of the University of Indianapolis could switch between campuses at any time.
Degrees, diplomas, certificates, and any other type of attestation awarded by universities in European Union and European Free Trade Association countries to students that have completed their studies in an accredited private college located in Greece, can be recognized as professionally equivalent "in terms of the professional (practice) rights only" (Greek: ) to higher education titles awarded in the formal Greek education system. Recognition of professional equivalence permits access to a specific economic activity that the title-holder can exercise on the same rules, rights, terms as holders of comparable titles of Greece HEIs education system.
Recognition of legally-recognized professional degree rights in Greece can only be granted by the Independent Department of Implementation of European Legislation (ATEEN; ) of the Ministry of Education (Υ.ΠΑΙ.Θ.), as of the 2005 Directive of the European Parliament and Council, implemented domestically by a presidential decree in 2010.
Higher Education qualifications obtained from abroad foreign countries are recognised by the Interdisciplinary Organisation of Recognition Academic Titles and Information (D.O.A.T.A.P.; Greek: ) supervised by the Ministry of Education (). The "Hellenic National Academic Recognition and Information Center (Hellenic NARIC)" is the official international name of DOATAP. In most cases, it can obtain a "statement of comparability" of a qualification (certificate of qualification equivalency information), stating how it compares to the qualifications delivered in Greece.
HAHE authority.
The Hellenic Quality Assurance and Accreditation Agency for Higher Education (ADIP; Greek: ), established by law 3374/2005, keeps the competent bodies of the state and the HEIs informed on current international developments and relevant issues. The ADIP was reformed by law
