More detailed information about environment get passed on child in preschool care and elementary school. Particular schools beside regular schooling and introducing environmental contents to some classes are offering broader opportunities for ecological education. They also give more attention to environmental preservation hence they are awarded with charter of International ecoschool and Green flag. Their status is renewed every two years if they manage to comply with standards, if not, schools can lose their ecoschool status. Main goal oft his study was to investigate impact of ecoschool status on ecological consciousness of its students. Participants in this study were 25 ecoschool students, age 9 to 10, and 22 regular school students, age 9 to 10. Results showed no connection between ecological consciousness and ecoschool status. However, results showed that regular schools have modernized implementation of teachingin a wa ythat involves more ecological contents in its regular curriculum. Conclusion is that classes additionally enriched with ecological contents and activities can have positive impact on ecological consciousness of its students and that that positive impact is not exclusively result of ecoschool status.
