This paper explores how primary school principals in the Republic of Ireland engage with the Anti-Bullying Procedures for Primary and Post-Primary Schools (DES 2013b). Informed by theoretical literature on policy enactment, the paper illustrates the complex, context-dependent process of enactment. Through qualitative interviews with ten primary school principals, the research uncovers the challenges they face in enacting standardised anti-bullying procedures in their unique school environments. The findings highlight the crucial role of principals in cultivating a positive school culture and managing the expectations of various stakeholders, including parents and teachers. Although distributed leadership is encouraged, the paper reveals that principals often carry the primary burden of responsibility, leading to feelings of isolation and significant pressure. Additionally, the research identifies considerable gaps in teacher education and professional learning. The paper advocates for more flexible, context-sensitive policies that provide better support for school leaders and recommends improved professional learning, shared leadership, and parental engagement to enhance the effectiveness of anti-bullying efforts. As the Department of Education in Ireland revises its anti-bullying procedures, this paper offers critical insights that can guide the development of more effective, supportive policies tailored to the complex realities faced by school leaders.
