This article presents a tool that provides reliable scores for studying the school climate from the students' perspective, created for the Romanian context. The main aim of the article is to present the psychometric properties of the instrument. The participants were 605 students, enrolled in four secondary schools and four high schools, from an urban area. The exploratory and confirmatory factor analyses revealed a seven-factor structure: student-teacher relationships, headmaster's involvement in school life, student-student relationships, school satisfaction, achievement motivation, student-form teacher relationship, and perceived safety. The results revealed that gender, school location, and parents' educational level could significantly predict school performances.
