L1, L2, L3: three acronyms that designate the three years of the bachelor’s cycle in the LMD system (bachelor-master-doctorate). Each level corresponds to an academic year validated by the acquisition of 60 ECTS credits, totaling 180 to obtain the bachelor’s degree. This architecture, harmonized at the European level, structures the training path of the majority of students enrolled in universities in France.
To delve into the meaning and differences between L1, L2, and L3, one must go beyond simple numbering and look at what actually changes from year to year in terms of content, requirements, and possibilities for reorientation.

Multidisciplinary portals in L1: a poorly supported filter
The first year of the bachelor’s program is no longer, in many universities, a direct entry into a single discipline. Multidisciplinary portals group several fields (law-political science, economics-management, human sciences) within the same semester, or even an entire year. The stated goal: to allow time for maturation before specialization.
The problem is concrete. The UNAF survey “Health and Studies of High School and University Students 2025-2026” reports a downward trend in the validation rate of the first semester, attributed to a lack of personalized support. Students find themselves facing a volume of subjects that can be disparate, without acquired academic methodology.

We observe that L1 functions as a double filter: disciplinary (understanding the expectations of the chosen field) and methodological (learning to work independently, managing a fragmented schedule). The workload in a multidisciplinary portal often exceeds that of a traditional L1, as the student must assimilate the fundamentals of several fields simultaneously.
ECTS and progression L2-L3: what compensation changes
Each validated semester earns 30 ECTS credits. The transition from L1 to L2, and then from L2 to L3, relies on the acquisition of these credits, but the compensation rules vary from one institution to another. Some universities apply annual compensation (the average of the two semesters is sufficient), while others require the validation of each unit of teaching.
This difference has direct consequences on the path. A student who compensates for a weak semester with a strong one earns their 60 annual ECTS, but may have gaps in fundamental subjects. In L3, these gaps become visible: the level of demand increases, the teachings specialize, and assessments mobilize skills presumed acquired in L1 and L2.
- In L2, specialization begins with the choice of pathways or options that orient towards a specific field (private or public law, quantitative economics or management, for example).
- In L3, the teachings incorporate a pre-professional or preparatory dimension for the master’s degree, with seminars, tutored projects, or internships depending on the field.
- Interdisciplinary minors, rapidly developing in several universities, allow for the completion of a major with a related field (computer science + management, literature + communication).
L3 is the year where the bachelor’s degree is at stake, but also the year where reorientation choices become the most strategic.
Bridges from L3 to BUT or schools: retaining accumulated ECTS
Standard guides present the bachelor’s degree as a linear three-year path. The reality is more fragmented. An increasing number of L3 students are considering a shift towards a BUT (bachelor of technology) or a post-bac school, without wanting to lose the credits they have accumulated.
Recognition of ECTS between bachelor’s and BUT
The ECTS system was designed to facilitate mobility. In practice, the recognition of credits depends on the educational commission of the host institution. A student who has validated 120 ECTS in the bachelor’s program (L1 + L2) can request integration into the third year of a BUT, but acceptance is not automatic. The commission evaluates the coherence between the courses taken and the reference framework of the targeted BUT.
Some universities and IUTs have formalized bridge agreements that precisely list the recognized units of teaching. Without an agreement, the student must compile an individual file, with transcripts and course descriptions, to validate their prior learning.
Alternation in L3: an underutilized lever
The IGÉSR report “Assessment of Work-Study Training in Higher Education” (March 2026) confirms a rising trend in work-study bachelor’s programs in L3, particularly in MIAGE programs and professional bachelor’s degrees. This formula allows for the validation of the degree while accumulating professional experience that subsequently facilitates entry into a master’s program or direct employment.
For a student in L3 who is hesitating between continuing to a master’s program and shifting to a more applied training, work-study in the bachelor’s program represents a compromise that secures both the degree and the CV.
Bachelor’s and master’s: what the L3 level determines for the future
The bachelor’s degree is a level bac+3 diploma (level 6 CITE in the international classification). It opens access to the master’s degree (bac+5), but the selection for entry into M1 transforms L3 into a decisive year. Universities examine the results of the three years, the coherence of the path, and complementary experiences (internships, Erasmus mobility, associative engagement).
We recommend not treating L3 as a mere validation year. The choice of options, the quality of the thesis or final project, and the construction of a readable profile for master’s commissions weigh as much as the overall average.
- The most sought-after bachelor’s degrees for master’s programs apply a selection based on application files from M1 onwards, with sometimes very low admission rates in law, psychology, or STAPS.
- A bachelor’s degree obtained with ECTS acquired through compensation may weaken a file if the compensated subjects correspond to the core of the targeted master’s program.
- Students who have followed an interdisciplinary minor or a work-study program have a differentiating element in their application.
The bachelor’s degree remains the foundation of the LMD system, but its value in the job market largely depends on the field, the chosen path, and the ability to articulate academic training and practical experience. The three years L1, L2, L3 are not three repetitions of the same exercise: each has its own logic, constraints, and opportunities for reorientation that students would benefit from anticipating from the first semester.
