This research explores the determinants of career success by examining the interplay between individual career attitudes and organizational career development practices in academia. Recognizing employability as a key predictor of career progression, the study differentiates between perceived internal and external employability to assess their mediating roles. Based on responses from 256 Malaysian academics, results show that protean career attitude does not directly impact career success but influences it indirectly through both internal and external employability perceptions. Organizational learning practices, in contrast, exert both direct and indirect effects on career success via employability perceptions. The analysis highlights that external employability has a stronger influence than internal employability in shaping career outcomes. These findings provide new insights into how individual adaptability and organizational learning contribute to academic career advancement, while also pointing to areas for further investigation and practical applications.
