Studying individuals and students’ attitudes towards environment and factors affecting students to be responsible individuals towards their environment may provide help towards the solution of environmental problems. In this study, it is aimed to evaluate environmental attitudes of high school students in terms of some variables. The sample of the study consists of 330 participants of whom 145 are male and 185 are female having studied in a High School in Balikesir (in western Turkey). In the study, as a means of data collection, Environmental Attitude Scale (EAS) and the personal information form have been used. The EAS which consists of 35 items is composed of 4 sub-dimensions as “Environmental awareness”, “Attitude toward recovery”, “Attitude toward recycling” and “Environmental consciousness and behavior”. According to the findings, considering the analysis of the EAS, statistically a considerable difference was reached between the sub-dimensions of the EAS and the gender, grade and parent education level variables. However, a considerable difference was not found between the branch of students and some sub-dimensions of the EAS.
