This study examines students' self-directed learning skills at Nong Lam University - Ho Chi Minh City, focusing on their attitudes and competencies in various aspects of autonomous learning. A quantitative research design was applied, and a cross-sectional survey was employed to explore the determinants of self-directed learning among undergraduate students systematically. The sample of 8,472 students was chosen using a convenience sampling method, and data were collected through a structured questionnaire based on the Self-Directed Learning Skills Scale (SDLSS). The research analyzes nine dimensions: attitudes towards learning (ATL), learning responsibility (LR), motivation and self-confidence (MS), the ability to plan learning (PL), the ability to use learning opportunities (ULO), ability to manage information (MI), ability to apply learning strategies (ALS), assessment of the learning process (ALP), and the evaluation of learning success/results (ELS). Findings indicate positive student attitudes, with average mean scores ranging from 3.5 to 4.2, suggesting high levels of agreement across these dimensions. Students demonstrated the most substantial commitment to responsibility for their learning, showing consistent accountability.
