Our study explored the professional characteristics and contexts of school-based environmental education (EE) leaders within elementary and secondary schools. Using complementary mixed-methods (surveys and focus groups) we detail the characteristics of EE leaders in these schools. Our analyses revealed that these leaders were predominantly classroom or subject-based teachers and experienced practitioners. They demonstrated the ability to negotiate the constraints of schools and implement school-wide EE initiatives due to their personal commitment to student learning about and for the environment. With our findings and using distributed leadership principles, we provide recommendations to support and enhance EE leadership in schools.
