Abstract
This qualitative multiple case study explored the responsibilities of teacher leaders in the classroom,
within the school, outside the school and in the community in the context of Nigerian public secondary
schools. It aimed to determine the extent of teacher leaders’ responsibilities in relation to national
development within and outside the school. Participants included nine teachers, three principals, viceprincipals
and an educational administrator in an Educational District in Lagos, Nigeria. Data for the
study was generated through the use of semi-structured interviews and documentary analysis. The
study revealed that the professional, administrative and social roles of teachers are a continuum within
and outside the school. It also shows that teachers spend majority of their time in the classroom as
well as assisting in administration and managerial processes in a school system. The study
recommends giving merit awards to teachers to enhance their image and self worth. It also
recommends that professional standards and training should be of importance in the teaching and
learning processes. The study contributes to professional development of teachers thereby enhancing
their responsibilities in and outside the schools.
