Among the qualities developed in science students is to become good caretakers of nature. Yet, ecological and health problems continue to occur related to poor solid waste management. This study aims to assess students’ ecological awareness, knowledge, practices, and impacts of solid waste management programs in flood prone DepEd and private senior high schools in Metro Manila. Descriptive-cross sectional design was used for the study with 535 senior high students using a random sampling technique. Using researcher-developed 4-point Likert Scale survey instrument, the data were collected, subjected to percentage, mean, standard deviation, t-test, and ANOVA statistical analyses at 0.05 level of significance with IBM SPSS v.20. Based on findings, it showed that majority of senior high school students were moderately aware of the ecological issues. These students were highly knowledgeable on ecological issues, problems, and ecological conditions. This implies a good information dissemination drive at the school level. It also showed that there is a significant difference in the level of awareness and practice between DepEd and private senior high schools, particularly in the level of ecological knowledge and its impact. Generally, a holistic approach to waste management education in school is vital to building dynamic solid waste management systems and programs.
