The use of coaching has been increasing in UK schools since the 1990s, as has interest in coaching among educational leaders and academics. Although research tends to focus on a specific facet of coaching in schools, it is also useful to take a broader approach and explore the overall coaching culture of schools. A coaching culture in schools is one in which “coaching values, principles and practices are part of the fabric of school life, influencing relationships, conversations, teaching, learning and leadership at all levels” (van Nieuwerburgh, 2012:17). Using interviews and questionnaires with eight headteachers involved in coaching, this study explored multiple facets of the “coaching values, principles and practices” in schools, with the results collectively providing an impression of their coaching culture. The focus was on comparing the headteachers’ responses to identify similarities and differences.
