Background: This study was motivated by the importance of developing self-leadership in students, which in turn influences their motivation, self-management, and responsibility in daily life. Self-leadership plays a crucial role in shaping students' character and influencing their academic and social success. Objective: This study aims to provide an overview of students' self-leadership and to design a personalized social guidance and counseling program to enhance students' self-leadership. Method: This study employed a quantitative descriptive research design with a random sampling technique, involving 106 second-year students at SMAN 1 Jawilan. This study used indicators of behavioral focus, natural reward strategies, and constructive thinking to measure students' self-leadership. Results: The results showed that 65% of students fell into the moderate self-leadership category, 19% into the high category, and 16% into the low category. Conclusion: Based on these results, it is essential to design a guidance program that enhances students' ability to lead themselves, manage their goals, and foster a greater sense of responsibility. Originality/Value: This study provides novel empirical insights in the field of developmental guidance and counseling, specifically within personal social counseling, by uncovering the distribution of high school students' self leadership profiles, revealing that the majority (65 percent) fall into the moderate category, along with specific developmental needs across behavior focused strategies, natural reward strategies, and constructive thought patterns, regarding adolescent self leadership competencies in the context of baseline school level need assessments for tailored counseling interventions, an area that has remained underexamined. These findings enrich empirical evidence and serve as a strategic benchmark for the development and implementation of structured personal social guidance programs and modular counseling interventions aimed at fostering students' self management, autonomy, and accountability in educational settings.
