Developing a good pro-pluralism religious education curriculum requires much planning and a deep understanding of the context. In a country like Iraq, where the education system is in decline due to years of conflict, weak governance and management, and a displacement crisis, this becomes a challenging task. This Learning Briefing, prepared during the implementation phase of the Coalition for Religious Equality and Inclusive Development (CREID) project to introduce reform to the religious education curriculum in Iraq, highlights the key areas of best practices and lessons learned from our stakeholder engagement. The aim is to share this learning with programme managers, donors and partners to help inform future interventions and curricula development on effective approaches and models for improved quality education.
