Environmental Science is one of the General Education subjects among college students that focuses on preservation and conservation of biological and physical aspects of the natural world by emphasizing problems and corresponding solutions. To understand these concepts and to demonstrate the Expected Lasallian Graduate Attributes (ELGAs) such as developing students to become critical thinkers, excellent communicators and socially responsible citizens, the transformative learning design was employed. Thus, this study aimed to evaluate the outcomes of employing the said design specifically in the attainment of ELGAs. This study used descriptive method of research with the aid of the questionnaire checklist and unstructured interview to assess students' perception regarding the level of attainment of the three expected learning outcomes among purposively sampled students who were enrolled in Environmental Science course during the SY 2010-2011 and 2011-2012. Based on the results of this study, an action plan for 2012 – 2013 and guideline for transformative learning were proposed.
