School climate describes the quality of the school environment. School climate is a construct that refers to the perceived structural, interpersonal, and learning aspects of a school; a positive school climate is associated with school success and academic achievement (Hoy & Hannum, 1997), prosocial development (Koth et al., 2008), and positive attitudes towards school (Kuperminc et al., 1997). Within educational literature, school climate has been studied across diverse populations to examine the experiences that students have encountered within their educational systems (Cohen et al., 2009). The series of evaluation briefs explores the relationship between (1) school climate (as measured by the Brief School Climate Survey for elementary and secondary students); (2) student-level demographics; and (3) Positive Behavioral Interventions and Supports (PBIS) Fidelity (as measured by the Tiered Fidelity Inventory (TFI). This brief examines the relationship between PBIS Fidelity and perceptions of school climate.
