Purpose: This study examines the current status of a second-degree Bachelor of Science in Nursing (BSN) program in South Korea, identifies its advantages and limitations, and provides future directions for improving the program. Methods: A mixed-methods, sequential explanatory design was employed. A cross-sectional survey (n=28 faculty members, 122 enrolled students, 20 graduates) was conducted, followed by focus group interviews (n=six faculty members, 13 enrolled students, six graduates). Results: Among the 28 nursing colleges, 19 had a second-degree BSN program enrollment capacity of less than 10% of their total student capacity, whereas six colleges had a capacity ranging from 20% to 30%. The advantages of the program included producing nurses with diverse backgrounds, demonstrating a strong aspiration for the nursing profession, diligent attitude, and mature interpersonal skills among the second-degree BSN students. The limitations included inadequate support and resources for program operations, difficulties in ensuring the quality of classes and clinical practice, and limited opportunities for interaction with other students. Conclusion: This study highlights the importance of establishing clear policies and guidelines for such programs and developing standardized curricula to ensure high-quality nursing education while accommodating an increasing number of students.
