Developing Christian moral values and making the students actively engage in community extension activities can be a challenge to the teachers and administrators. Thus, this study sought to determine the relationship between the Christian moral values and prosocial behavior of the students and their involvement in community extension activities. This study used a descriptive correlation research design involving 517 third year college students selected through stratified quota sampling technique from the nine member schools of the Davao Association of Catholic Schools (DACS).” The data revealed that the respondents’ Christian moral values and prosocial behavior are significantly related to their involvement in community extension. Moreover, moral values and prosocial behavior are predictors of the student involvement in community extension.
