Development and Validation of the Teachers’ Perceptions of Classroom Climate Scale for the Portuguese Population

To improve learning outcomes, evidence-based processes suggest that classroom climate is a means of creating more sustainable schools committed to improving the quality of teaching and learning. Therefore, valid measures of classroom climate are necessary to enable comparative studies focused on teachers' perceptions, including important dimensions such as cooperation. As no validated instruments exist for the Portuguese context, we developed and validated the Teachers' Perception of Classroom Climate (TPCC), consisting of five dimensions: teacher support, peer support, academic competence, satisfaction with the school, and cooperation. Following a quantitative research approach, the construct validity was analyzed using Confirmatory Factor Analysis, internal consistency was evaluated using Cronbach’s Alpha coefficient, and test-retest reliability was assessed using univariate and multivariate General Linear Models and Spearman’s rho correlations. The study supported the five-factor structure of the TPCC and demonstrated good psychometric properties. These results support the use of the TPCC to evaluate teacher perceptions of classroom climate.
