School climate is a topic of increasing importance internationally. The current study investigated the established measurement invariance of an eight-factor school climate scale using a multi-national sample of secondary students. School climate factor means across 14 international groups were compared and findings on the association between school climate factors and mental health were also investigated. Findings from this study illustrate several

Teachers’ collective efficacy is predictive of students’ success. School-Wide Positive Behavior Interventions and Supports implementation requires the whole team to set itself common goals regarding behavior management. The main purpose of this study was to investigate the medium-term effects of a SWPBIS intervention on teachers’ collective efficacy. Nine schools and 139 teachers and staff members (n intervention = 74, n control = 65) took part in the study. The study shows that SWPBIS implementation has a positive effect on teachers’ collective efficacy both for primary and secondary schools at post-test 1 (ES = +0.80) and 2 (ES = +0.71). Differences are observed at baseline and at posttests according to the educational level. The link between subscales of a school climate instrument and teachers’ collective efficacy is also investigated. The “structure for learning” subscale explains the greatest variance in collective efficacy.

School-Wide Positive Behavior Interventions and Supports is a framework that aims to improve school culture and climate, students’ behavior and attendance. As the program is largely spreading, comparative studies showing its efficacy on students’ outside the United States are needed. In addition, there is a need for studies examining SWPBIS effects on school climate from all the stakeholders’ point of view, especially students and parents. Moreover, few researches used comprehensive questionnaires including the three main components of school climate: engagement, safety and environment. The purpose of this study is twofold: investigate the SWPBIS implementation feasibility in a French speaking European country and measure implementation effects on school climate and absenteeism. Using a quasi-experimental design, the current study investigates the impact of SWPBIS implementation in elementary and secondary high-need schools (n intervention schools = 4, n control schools = 5). Findings show positive effects for all stakeholders on different components of school climate. Effects on absenteeism are mixed. Implications and limitations are discussed.
