This study presents evidence of the validity and reliability of scores for the newly developed Brazilian Portuguese version of the Delaware School Climate Survey-Student (Brazilian DSCS-S). The sample consisted of 378 students, grades 5 through 9, attending four private and three public schools in southern Brazil. Confirmatory factor analyses supported both a bifactor model and a six-factor model, but support was stronger for the latter. Most scores across factors correlated significantly with students' self-reported cognitive-behavioral and emotional engagement in school. As discussed, the Brazilian DSCS-S provides schools with a useful tool for conducting needs assessments and evaluating programs in Brazilian schools.
