The School social climate has been object study by various disciplines including: The sociology, psychology and pedagogy, given its complexity and multifactorial nature. This article discusses the adaptation and validation of School Social Climate Scale (CES) originally developed by Moos & Trickett (1979), whose objective is oriented to the construction of reliable tools for the analysis of variables related with formation process in a school setting. This is a non-experimental psychometric study. The sample involves 204 students in grades 6th, 7th, 8th, two educational institutions in the city of Bogotá (one public and one private), aged between 10 and 14 years old. The validation process is done through pilot study before, observing analysis of reagents and verbal semantic aspects and the concep of expert expert judges. The confiability was obtained from the model of the two halves, with the alternative equation proposed by Rulon reaching values between 0.8 and 1 for all categories; this index is corroborated with Cronbach's Alpha which reached a value of 0.9. The content validity analysis was done through the criterion of seven expert judges, finding a level agreement between judges from 95% to locate the items in their conceptual domain and the Kappa concordance rates reached values of 0.74.
