Early School Leaving (ESL), or Early Leaving from Education and Training (ELET), remains a critical challenge across Europe and globally, with profound implications encompassing economic disadvantages, social exclusion, and reduced life opportunities for individuals. This entry analyzes the authoritative definition of the phenomenon, explores the multifaceted causes that drive it, and outlines the severe professional, social, and psychological consequences of failing to attain a minimal credential. ESL is widely understood not as an abrupt event but as a complex, cumulative, long-term process of school disengagement that is influenced by a myriad of interconnected risk factors originating in childhood and early adolescence. Understanding the interplay between individual, family, and institutional factors is crucial for designing effective, coordinated policy responses.
At the European Union (EU) level, the concept of ELET is officially defined as the percentage of the population aged 18 to 24 years old who have completed at most a lower secondary education, International Standard Classification of Education (ISCED) 2011 levels 0, 1, or 2, and who were not involved in any further education or training during the four weeks preceding the labor force survey [

ELET is considered a major social concern and its prevention is a strategic objective and a top policy priority throughout the EU [

Numerous other educational and social issues are closely related to the ESL phenomenon. A related term, underachievement, is the failure to meet predetermined achievement objectives for a particular age group. This can manifest as negative behaviors like learning difficulties, chronic absenteeism, low motivation, and grade repetition [

Another commonly used metric related to ESL is the status of being NEET (Not in Education, Employment, or Training) [
10,
11]. Young people who have low educational attainment face a high risk of being NEET. The European Pillar of Social Rights Action Plan includes an objective to decrease the NEET rate to below 9% by 2030 [

These influences operate at multiple levels—individual, family, socioeconomic, institutional, and structural—and their combined effects shape students’ engagement, achievement, and educational trajectories.
