The population of the study was allSenior High School students of Divine Word College of Vigan. The data were gathered throughvalidated questionnaires. In order to analyse the data, statistical tools were used such as weighted mean was used to determine the level of cognitive and affective attitude toward environment and environmental behaviour, while the Pearson r was used to determine the correlation between cognitive and affective attitude toward environment and environmental behaviour. The study found that students have very high on cognitive and affective attitude toward environment particularly on anthropocentric and eco-centric view of the environment.
