Cambodia is a country dense with Non-Governmental Organizations (NGOs) and the third sector of the country is active in education. Educational NGOs in Cambodia vary in many aspects; however, many education programs exhibit the capacity to facilitate social and emotional learning (SEL). This study aims to compare two different NGOs and their respective influences on student SEL to identify positive features leading to increased SEL levels. Through a mixed-method design involving surveys, interviews, and observations, this research compares and evaluates two educational NGOs programs, SOS Childrens Village (SOS) and Village Development Program (VDP), as well as their effectiveness in fostering Cambodian youth SEL development. The results show higher levels of social awareness and relationship skills within VDP. Regression analysis reveals a negative correlation between the socioeconomic control with self-management and responsible decision making. The results obtained in the study could provide information for the educational program design regarding SEL and present valuable insight into two educational NGOs operating in Cambodia.
