Adult learner dropout is adults’ withdrawal or stop-out from formal or non-formal educational programs before successful completion. For adult learners, withdrawal often manifests as stop-out or temporary disengagement rather than permanent attrition, reflecting the episodic nature of their participation. Unlike traditional students, adult learners must often balance multiple life responsibilities—employment, caregiving, financial obligations, and community roles—while also pursuing education or training. Their vulnerability to attrition is further exacerbated by these overlapping demands, particularly when educational programs do not accommodate their situational and motivational needs. Adult learner dropout therefore requires a more dynamic understanding of persistence as a continuous negotiation between internal and external demands. Participation in online education has significantly expanded over the past two decades, particularly during and after the COVID-19 pandemic, as adult learners increasingly engage with digital platforms for work and communication. This exposure has enhanced their digital fluency, transforming their expectations and experiences of online learning. Thus, the underlying factors that influence adult learner dropout have also shifted—moving beyond technological and access-related barriers to instructional quality, engagement design, and relevance issues. In this evolving landscape, adult learner dropout can no longer be regarded as isolated or individual events. It is a systemic phenomenon emerging from dynamic interactions among psychological, pedagogical, contextual, and institutional factors.
