This study evaluates the Green School Program in Guimaras, Philippines, based on the ratings provided by internal and external stakeholders. Internal stakeholders, including principals, head teachers, teachers, and students, gave an overall rating of M=3.87, with a descriptive rating of “good” in all five areas: physical aspects, curriculum, program, practices, and culture. External stakeholders, including LGU, PTA, and alumni, rated the program as a whole with an M=3.65 and a descriptive rating of “good” in all five areas. However, the mean rating for each area was lower than that of internal stakeholders. In terms of physical aspects, internal stakeholders rated the program with an M=3.98, while external stakeholders rated it with an M=3.75. For the curriculum, internal stakeholders rated the program with an M=4.00, while external stakeholders rated it with an M=3.87. This indicates that internal stakeholders are more comfortable with the program than external stakeholders. The study also reveals that the use of LED lights is not popular among schools, and external stakeholders are not fully aware of the benefits derived from using environmentally friendly lighting. The study suggests that the Green School Program needs further improvement to be fully implemented, particularly in some areas.
