Confusion among school leaders regarding how to interpret and implement special education legislation, and specific federal and state policies and mandates such as a free and appropriate public education (FAPE), in the least restrictive environment (LRE) at the school-site level has existed since the 1970s and continues to exist. This metasynthesis explores the literature surrounding sensemaking by which building principals adapt and transform policy as they enact it in their schools. Findings suggest that a phenomenon of internal forces had a more significant influence on the actions that took place throughout their sensemaking of LRE and FAPE.
