This paper explored racial discrimination as the primary underlying factor which creates an unwelcoming campus racial climate for Black students in K-12 public schools. It also highlights how the validation of the White race over the Black race perpetuates racial discrimination in the form of institutional racism. It shows how institutional racism creates negative relationships between most Black students and their White teachers, resulting in hostile campus racial climates. This paper, through the lenses of racial battle fatigue and critical race theory, argues that hostile campus racial climate results in a lack of sense of belonging among Black students in K-12 public schools. In addition, this paper demonstrates that the negative relationship that often exists between Blac k students and White teachers is due to negative perceptions (deficit thinking) and behaviors of White teachers. Various ways White teachers can help eliminate hostile campus racial climate against Black students are discussed. Data for this study were collected through the review of scholarly literature that discussed the experiences and negative effects of campus racial climate on the relationship between most White teachers and Black students in K-12 public schools.

Campus racial climate accounts for the issues and practices of racial equity in schools to accommodate the racially minoritized students, and the promotion of these practices results in a positive campus racial climate (Hart & Fellabaum, 2008). Hart and Fellabaum (2008) added that campus racial climate is a set of attributes, such as perception and attitudes, which shape the ways organizations deal with their members. By emphasizing the two key concepts, perception and attitudes, Hart and Fellabaum (2008) showed the importance of the members of an organization's discernment on the way they understand and react to or behave toward their members. While Hart and Fellabaum (2008) was based on the higher education experience of racial campus climate, research has demonstrated that higher education and the K-12 public schools are tightly held together on the issues concerning racial equity as both perpetuate racially imbalanced attitudes and perceptions that do not support racial and ethnic diversity (Wells, 2020). This is pertinent because presently, "more than any other time in U.S. history, Black students are being educated by people who are not o f their racial or cultural background" (Douglas et al, 2008, p. 48). According to the report published by the National Center on Education Statistics in 2019, White teachers accounted for 90 % of staff at elementary and secondary schools with more minoritized students. These statistics demonstrate that most Black students in K-12 public schools are taught by White teachers. Despite the imp...
