This investigation is a subset of a larger study (Fitchett et al., 2020; Lambert et al., 2020; McCarthy et al., 2020) of the relationship between a teacher’s racial / ethnic congruence with the students in their school and occupational stress. Prior to comparing congruent and incongruent teachers on indictors of stress, the researchers sought to investigate whether teachers working in congruent and incongruent school settings are equivalent with respect to personal characteristics, professional qualifications, and contextual factors.
