Abstract. This study assesses the performance and challenges of the Sangguniang Kabataan (SK) in a city in Bukidnon, Philippines, under the SK Reform Act of 2015 (RA 10742), and proposes a capacity-building framework. Employing a mixed-methods explanatory sequential design, quantitative data from 113 SK officials were collected via surveys, followed by qualitative insights from interviews and focus group discussions with 20 officials. Results indicated a "Very Satisfactory" overall performance (mean: 4.12, SD: 0.25), with notable achievements in mandated duties, planning, program management, and government engagement. However, lower performance in meeting facilitation, monitoring/reporting, and resolution revealed deficits in administrative and technical competency. Key challenges included resource limitations, capacity gaps, declining youth engagement, and systemic barriers. Addressing these, the study introduces a Capacity Enhancement and Governance Sustainability Framework, a multi-level intervention, integrating individual, institutional, and systemic reforms. This research contributes to empowering young leaders, advancing democratic participation, and fostering effective governance in the Philippines, while also addressing the mandate-resource mismatch prevalent in decentralized governance systems.
