A study of two schools in northern Australia demonstrated the impact on Education for Sustainability (EfS) initiatives of a disruptive policy environment set in motion by neoliberal reforms focused on standards, accountability, and international competitiveness. In one of the schools, a culture characterized by trust and an emphasis on cultivating teacher and student strengths and interests contributed to the resilience of these initiatives in the face of outside pressures. In the other, administrators preoccupied with the need to implement state mandates with fidelity failed to nurture and develop a collection of remarkable EfS projects and activities.
