This research developed a life skills structured learning experience (SLE) module for the adolescents in the long-term residential care center using the results of triangulation method of needs assessment. Employing an action research design that used both quantitative and qualitative methods, the researchers assessed the needs of the respondents in three levels namely: person level, job level, and organizational level. The responses came from the total enumeration of the social workers and house parents in the Institution and from the inputs of the adolescents through self-awareness group dynamics activity. With the results of the triangulated needs assessment, the researchers developed a research-based structured learning experience (SLE) module by considering the leading themes that were extracted from the responses of the adolescents, house parents, and social workers. Lastly, the researchers developed an evaluation tool aimed to measure the effectiveness of the SLE module based on the reaction and learning of the participants after the activity. This was in line with the concept of Kirkpatrick’s four levels of evaluation and the evaluation tool of the Institution.
