This qualitative dissertation, positioned within a critical consciousness conceptual framework examined the shared experiences of eight Southeast Asian youth, as they engaged in an activism internship at a movement-based youth program. It documented the internship, within the context of the youth program, where the researcher served as a mentor and advocate for six years. This dissertation study followed the interns as they engaged in lessons and direct actions focused on social, racial, and gender justice. Further, it explored how engagement as an intern shaped the immigrant youth experiences and developed their critical consciousness in the face of anti-immigrant rhetoric and policies, and systemic discrimination. Data were collected, first informally for five years preceding this study, in the form of field observations as the researcher engaged as a mentor and advocate with the youth program. During the course of the activism internship, data were collected through individual interviews, field observations, and archived data analysis. Each participant’s experiences were examined, and themes emerged through the development of a short case study using their interviews, observations, and data collected through the examination of their final projects. The youth participants’ shared experiences along with an analysis through a critical consciousness lens reveal that engagement in an activism internship developed their critical reflection, political efficacy, and critical action. The findings of this study indicated that the shared experiences of the participants, including engagement as an activism intern, allowed for the development of their critical consciousness. While this process was ongoing, and each participant approached their time as an intern at different points in the development process, the activism internship exposed the participants to issues impacting the Southeast Asian community. Engagement as an intern also allowed the participants to examine the systems within which they live, and learn how to take action against those systems. Further, this study exposed how community-based organizations allow immigrant youth the space and experiences to deeply examine anti-immigrant systems and policies. Findings of this study added to critical consciousness theory scholarship, which empowers marginalized peoples to take action against oppressive forces. It informed future research by exposing the need for community-based organizations to incorporate activism and advocacy programming.
