This study aimed to design and validate an instrument to measure the school climate in basic and secondary education institutions in Bogotá. The research focused on the perceptions of teachers regarding their work environment. A quantitative, psychometric methodology was used, involving standardized data analysis and a questionnaire with 50 items administered to a non-probabilistic, intentional sample of 432 teachers. The study proposed six dimensions of the school climate: structure and processes, infrastructure, decision-making, interpersonal relationships, compensation, and sense of belonging. The results showed high reliability (Cronbach's alpha of 0.94) and construct validity, explaining 48% of the variance for seven factors corresponding to the six dimensions. The instrument was found to have adequate psychometric properties and is relevant for understanding the educational environment from the teachers' perspective. The study contributes to the understanding of educational institutions by analyzing the school climate through teacher perceptions, which influence teaching processes, student learning, and the institution's image. The instrument is useful for diagnosing the school climate effectively and improving educational quality. Key words: basic and secondary school teachers, educational institutions, teacher working conditions, school climate.This study aimed to design and validate an instrument to measure the school climate in basic and secondary education institutions in Bogotá.
