<![CDATA[The Adiwiyata program, as part of environmental education in schools, plays an important role in shaping students’ ecological awareness. This study aims to evaluate the implementation of the Adiwiyata Program at SMA Negeri 4 Bogor, which has been designated as a National Adiwiyata School since 2022. The evaluation was conducted to monitor the sustainability of environmentally based programs that strengthen students’ environmental awareness and character. The research employed the CSE-UCLA evaluation model, covering five key areas: system assessment, program planning, program implementation, program improvement, and program certification. A qualitative research approach was used, involving interviews, focus group discussions, observations, and document analysis to obtain a comprehensive understanding of the program implementation. The findings indicate that SMA Negeri 4 Bogor has successfully implemented the Adiwiyata Program through well-integrated policies within the curriculum, structured planning, and environmental activities involving school members and external partners. Program improvement is demonstrated through the use of environmentally friendly products, capacity-building initiatives, and collaboration with local government programs. The program has also contributed to enhancing students' environmental awareness and character development. However, further efforts are needed to expand students' environmental awareness and character development, strengthen partnerships, and optimize the use of environmentally friendly technology to ensure long-term program sustainability.
