This paper reports on an instrumental case study exploring what migrant and refugee-background youth in Australia make of the critical media literacy they learn in school, and what critical media practices they use out of school. It addresses the perennial question of the relationship between school literacy learning and everyday literate lives, paying deliberate attention to the experiences of youth whose diversity is underrepresented in research. Interviews with two English teachers and focus groups with culturally and linguistically diverse Year 10 students were analysed using content analysis and the concept of recontextualization. Findings are that these youth see significant value in their critical literacy learning at school, and they report utilising the types of critical reading/viewing skills they experience at school but for different purposes. They frequently use five main strategies for critical reading/viewing out of school: (1) using awareness of myriad multimodal semiotic features to examine representations of products and information; (2) evaluating trustworthiness; (3) fact checking; (4) doing further research; (5) identifying attempts at positioning. This research brings in-school and out-of-school domains together to understand the connections between critical literacy practices undertaken in school, and those reshaped by immigrant youth, who are still learning English, out of school.
