This article presents a qualitative evaluation of the EcoSchool program in the Czech Republic. In order to analyze the way in which pupils interpret the purpose of their membership in EcoTeams, eight focus groups in schools highly involved in the program were interviewed (N = 83). The study is based on the assumption that the implementation of the program varies from a highly instrumental to a highly emancipatory approach. As a result, the analysis found significant differences between EcoTeams in terms of the level of pupils' participation in decision-making processes, their satisfaction with the program, and their identification with the program's outcomes.
