Researchers have found that compared to the support offered at tribal colleges and universities (TCUs), American Indian students at predominantly White institutions (PWIs) face a lack of support (Bryan, 2019). TCUs create environments that foster students' sense of belonging and their sense of self (Shorty & Robinson Kurpius, 2021). "Sense of belonging" for American Indian students refers to their "perceptions of being valued within a campus community" (Oxendine et al., 2020, p. 269). TCUs preserve Native cultures and encourage Native nation-building through academic programming and associated curriculum that support tribal communities (Neutuch, 2018). As institutions and through their curriculum, TCUs reflect and honor tribal practices and Indigenous cultures, knowledges, values, and languages, which affirms students' identities as American Indians (Crazy Bull & Guillory, 2018; Huaman et al., 2019; Nguyen et al., 2019). TCU staff and faculty mentor students and partner with their families to create a support network that honors students' cultural backgrounds and community, helping retain Native students at TCUs (Bryan, 2019; HeavyRunner & DeCelles, 2002; Nguyen et al., 2019). This study examines the unknown extent to which American Indian students' sense of belonging at PWIs compared to American Indian students' sense of belonging at TCUs (Oxendine et al., 2020; Oxendine & Taub, 2021).
