This presentation highlights the design of my doctoral research utilizing testimonio as a decolonial method and methodology. The study examines the intersection of cultural identity, educational equity, and maternal involvement through the lived experiences of ten first-generation Latinx immigrant mothers. Its purpose is to analyze these mothers' experiences, communication, and activities in supporting their children’s educational success. Grounded in testimonio as a Latina feminist methodology and epistemology, the study draws on data collected through in-depth, semi-structured interviews conducted in Spanish, resulting in ten testimonios of maternal involvement.
