This Self-Reflection Tool was developed as part of the Inclusive Early Childhood Education (IECE) project, conducted by the European Agency for Special Needs and Inclusive Education from 2015 to 2017 (www.european-agency.org/agency-projects/inclusive-early-childhood-education). The project’s overall goal was to identify, analyse and subsequently promote the main characteristics of quality IECE for all children. To that end, a need was detected for a tool that all professionals and staff could use to reflect on their setting’s inclusiveness, focusing on the social, learning and physical environment. This tool is intended to help improve settings’ inclusiveness.
