Our Stories: Black Parents’ Experiences At K-12 Predominantly White Institutions, Jason Thompson

Dissertations

Black parents of Black children attending K–12 predominantly White institutions (PWIs) often experience stress as they navigate school environments where they may be perceived as uninterested, combative, or “token” members of the school community. These deficit-based perceptions can cause Black parents to limit school interactions, question whether their perspectives will be valued, and develop distrust toward school personnel. Although research has examined Black students’ experiences in PWIs, fewer qualitative studies have centered on Black parents’ stories. Capturing these experiences in parents’ own words helps challenge harmful stereotypes and offers schools, especially school counselors, deeper insight into strengthening relationships with Black …
