The essay aims to critically-interpretatively analyze the phenomenon of school lag of boys in relation to girls in high school, a theme in which gender-related factors are combined with race and class issues. In any case, admitting that black boys from poor sections of the population are the main victims of school failure, the discussion of the construction of racialized masculinities and the relationship they establish with the schooling process is imperative. The text has an argumentative character as it is restricted to the intersections between the political-scientific clashes of racial and gender relations, of black masculinities, of power relations, of subjectivities and racialized masculine identities, of state violence; all this based, effectively, on theoretical-empirical studies.
