The French university system is based on three letters and a number: L1, L2, L3. These abbreviations refer to the three years of the bachelor’s degree, the first level of the LMD (licence-master-doctorat) framework. Understanding what L1, L2, and L3 mean allows one to place each year within a European framework built around ECTS credits, rather than just the final diploma.
ECTS Credits and Bachelor’s Degree: the Mechanism the Acronym Doesn’t Mention
L1, L2, L3 are not just simple chronological labels. Each year corresponds to the acquisition of 60 ECTS credits, for a total of 180 credits upon completion of the bachelor’s degree. This credit accumulation system was introduced to make academic paths more understandable across the entire European higher education area.

An ECTS credit represents a total workload: lectures, tutorials, personal work, and possible internships. The distribution varies by university and field of study, but the total volume per year remains the same, whether studying sciences, arts, or law.
The practical advantage of the system lies in its portability. A student who completes their L1 in France and wishes to continue in L2 at another European university can present their 60 credits. Equivalences are not automatic, but the ECTS framework significantly simplifies the process compared to the old pre-LMD system.

To better understand what L1 L2 L3 means in this context, one must look beyond the simple annual division.
L1, L2, L3: What Really Changes from Year to Year
The first year of the bachelor’s degree (L1) is a year of discovery. The courses remain largely multidisciplinary: a student enrolled in a science bachelor’s program may take modules in mathematics, physics, and chemistry before specializing. The rate of reorientation after L1 is the highest of the cycle, reflecting the exploratory role of this year.
L2: The Beginning of Specialization
In the second year, the program narrows around the main discipline. Optional teaching units gradually give way to specialized subjects. This is also the time when the first methodological requirements (long essays, research reports, structured presentations) intensify.
L3: Preparing for Graduation or Further Studies
L3 is the graduating year of the bachelor’s degree. A student who validates their 180 ECTS credits receives a diploma at the bac+3 level, recognized at level 6 of the national framework for professional certifications. Two options then arise: enter the job market or apply for a master’s program (M1).
L3 often includes an internship or a supervised project, depending on the field. In sciences, arts, literature, or multidisciplinary training, the content varies, but the logic remains the same: consolidate disciplinary knowledge and prepare for a transition, whether professional or academic.
Bachelor’s Degree, Bachelor, BUT: Do Not Confuse Bac+3 Diplomas
The French landscape at bac+3 has become more complex. Several diplomas coexist at this level, and their differences do not depend on the number of years of study, but on the nature of the training and the institution that issues it.
- The university bachelor’s degree (L1-L2-L3) is awarded by public universities. It automatically confers the bachelor’s degree and opens access to university master’s programs.
- The bachelor, offered by private schools (business, arts, communication), does not automatically confer the bachelor’s degree. For this, the program must have received specific accreditation. Without this recognition, the diploma remains a school title.
- The BUT (bachelor universitaire de technologie), awarded by IUTs, is a national diploma in three years that confers the bachelor’s degree since the reform that replaced the DUT as the exit diploma at bac+2.
Checking whether a diploma confers the bachelor’s degree is an essential precaution before committing to a program, as this degree conditions access to competitions and master’s programs.
The LMD Framework and the Classification of Diploma Levels in France
The LMD system structures French higher education into three cycles:
- First cycle: the bachelor’s degree (bac+3, 180 ECTS), which corresponds to levels L1, L2, and L3.
- Second cycle: the master’s degree (bac+5, 300 ECTS accumulated), divided into M1 and M2.
- Third cycle: the doctorate (bac+8), accessible after a master’s degree.
This structure was adopted to harmonize European diplomas. Before the LMD, the first university cycle in France was divided into DEUG (two years) and then bachelor’s degree (one year), with a different logic. The transition to LMD unified the bachelor’s degree into a three-year block, making the path more understandable for employers and foreign institutions.
The official classification, as described by the public service, ranks the bachelor’s degree at level 6 (formerly level II). This classification serves as a reference for administrative competitions, collective agreements, and recognition of professional qualifications.
Reorientation and Pathways Between Bachelor’s Levels
One point that guidance counselors rarely address precisely: pathways between fields during the bachelor’s program. A student in L1 sciences who wishes to switch to a bachelor’s degree in arts or literature does not necessarily start from scratch. The validated ECTS credits in transversal units (languages, methodology, computer science) can be retained.
Field reports vary on this point. Some universities facilitate reorientations as early as the end of the first semester of L1, with “staggered entry” arrangements in January. Others only allow field changes between two academic years. Conditions vary from one institution to another, and there is no uniform national rule on this subject.
For a student in L2 or L3, changing fields generally involves having their file examined by a pedagogical commission that decides on transferable credits. The outcome depends on the degree of proximity between the two disciplines and the specific content of the validated courses.
The bachelor’s degree remains the foundation of the French university path, but its interpretation is not limited to three letters followed by a number. Behind L1, L2, and L3 lies a system of cumulative credits, progressive specializations, and variable pathways that structure higher education, with rules that often differ from one university to another.
