This study aims to verify green practice constructs using a confirmatory factor analysis (CFA). A total of 100 secondary school students were selected as a study sample using a simple random sampling technique. The green practice constructs consisted of five major subconstructs, paper resource management practices, electricity-saving practices, water-saving practices, recycling, and eco-friendly product consumption. The constructs included 37 items and used a five-point Likert scale. The data obtained were processed through an exploratory factor analysis (EFA) to ascertain the structure of the green practice determinants. Then, a confirmatory factor analysis (CFA) was used to find the measurement model for each construct using AMOS software. The results showed that the measurement model fit the data obtained which the value of the fit indices of CMIN/DF, TLI, CFI, IFI, NFI and RMSEA were used to produce the appropriate model. As a result, a total of 17 items were retained, consisting of recycling management practices (four items), electricity-saving practices (three items), eco-friendly product consumption (three items), paper resource management (four items), and water-saving practice (three items). Overall, the constructs were valid and credible for measuring green practice in the context of this study. The implication of this study will positively lead to the implementation of "going green" to pursue knowledge and practices that can lead to more environmentally friendly and ecologically responsible decisions and lifestyle, which can help protect the environment and sustain its natural resources for current and future generations in Malaysia.
