The aim of this paper is to explore high school students' critical consciousness development in the context of youth participatory action research (YPAR) focused on food security at an alternative school in Alabama. The YPAR project took place in an elective agriscience class with 10 students (Seven Black, two white, one Latino) who were in the 10th to 12th grades. Utilizing data from researcher notes, classroom observations, and archival classroom documents, we present students' YPAR project outcomes to share their research-driven solutions to food insecurity in their community. Vignettes of classroom dialogue are also constructed to illustrate moments of reflection in the YPAR context about food security. We present three "critical moments," or instances of social analysis, to illustrate how students' individual-level attributions occurred alongside teacher dialogue and student-led investigation of structural inequities in the community. Findings illustrate how students' nonlinear critical consciousness development consisted of reliance on individual-level attributions in classroom dialogue co-occurring with systems-thinking activities and other YPAR project outcomes. This paper has implications for research on the imperfect and wavering nature of adolescent critical consciousness development in YPAR.
