Resumen: En este estudio se evalúa la percepción del clima escolar de dos grupos de profesores de dos centros educativos. El primer grupo (grupo experimental) ha implantado un programa de convivencia escolar, el otro (grupo de control) no. En esta investigación participaron 48 profesores que cumplimentaron la Escala de Percepción del Clima y del Funcionamiento del Centro (24 del centro experimental y 24 del centro que sirvió como grupo de control). Se encontraron diferencias estadísticamente signifi cativas a favor del centro experimental en diferentes ítems de la escala, así como en dos de los seis factores evaluados. En lí-neas generales, los docentes perciben un mejor clima y un mejor funcionamiento en el centro experimental.Palabras clave: educación primaria; convivencia escolar; clima escolar; evaluación. Abstract:The aim of this work was to assess the perceptions about school climate in two groups of teachers from two different primary schools. The fi rst group (experimental group) has implemented a program of school coexistence, the other (control group) did not. This research involved 48 teachers who completed the Perception Scale Climate (24 from experimental center and 24 from control group). Statistically signifi cant differences were found in favor of experimental center. Differences between the experimental center and control group were found in different scale items, as well as in two of the six evaluated factors. In general, teachers from the experimental group perceived better school climate than teachers from control group.
