This study aims to analyze the transformation of the educational pattern at the Indonesian Naval Academy (AAL) from a four-year to a three-year system and its impact on graduate competencies and operational readiness. This educational system change responds to budget efficiency needs and accelerated officer formation filling, yet raises questions about the new system's ability to maintain the quality of officer education. The research employs a mixed methods approach with a concurrent embedded design, involving 250 respondents comprising graduates from both educational systems, AAL instructors, and unit commanders receiving graduates. Quantitative data were collected through structured questionnaires and analyzed using descriptive and inferential statistics (independent sample t-test and regression), while qualitative data were obtained through in-depth interviews, observations, and document studies analyzed using thematic analysis. Results indicate no significant difference in overall Grade Point Average (GPA) between the two groups (p=0.470), but significant differences in competency patterns emerged: four-year system graduates excelled in theoretical competencies (p=0.001), while three-year system graduates excelled in practical competencies (p=0.003). Operational readiness evaluation shows that four-year system graduates obtained higher scores (82.5) compared to three-year system graduates (78.3), with significant differences (p=0.012), particularly in strategic leadership and complex decision-making aspects. Qualitative analysis identified five major themes: high learning time pressure, orientation shift from comprehensive to pragmatic, gaps in character formation and corps values, concerns about theoretical understanding depth, and need for more intensive post-graduation mentoring programs. This study concludes that educational time compression successfully increased operational efficiency but involved trade-offs in learning depth and professional maturity. To optimize the three-year educational system, a comprehensive approach is required, including curriculum revision with integrated learning methods, utilization of modern learning technology, strengthening of leadership development programs, and development of continuous professional mentoring systems. The recommendations of this research are expected to provide input for AAL and the Indonesian Navy in refining the officer education system to produce officers who are not only technically competent but also mature in leadership and strong in character.
