Recent years have seen a greatly enhanced focus on the learning needs of schools leaders. This paper examines the perceptions of such leaders about the best ways of enhancing leadership skills. Data were collected by semi-structured interviews with 34 headteacher respondents in 18 schools. Findings reveal that most respondents expressed a preference for forms of mentoring and experiential leadership development rather than formal courses. More specifically, results suggested that headteachers should be encouraged to take increased responsibilities for developing new and future leaders in the context of individual schools and through more informal and experiential learning. It is also suggested that future empirical investigation focus on headteachers' contribution to the stimulation of school leaders' professional learning.
