Harris and Muijs argue that teachers’ leadership beyond their own classrooms is an important capacity for school improvement. Drawing on research and school examples, they describe teacher leaders as influencing colleagues, leading pedagogical development, coordinating improvement work, coaching or mentoring, and contributing to collective decisions without necessarily holding senior posts.
The book connects leadership with professional collaboration, development, and improved teaching and learning rather than treating it simply as delegated administration. It examines roles, responsibilities, organisational conditions, professional learning, and ways schools can foster participation. Support from principals, time, trust, recognition, clear purposes, and cultures that value teachers’ expertise enable teacher leadership; hierarchy, isolation, role ambiguity, and overloaded volunteers can constrain it. The authors do not suggest that appointing more formal post-holders automatically raises achievement.
Their central proposition is that schools improve when they deliberately develop teachers’ agency and expertise, distribute meaningful influence, connect leadership activity to classroom learning, and create structures through which colleagues can learn and act together.

Hattie’s policy report argues that education systems should shift attention from structural fixes toward collaborative professional expertise focused on the impact of teaching.
It proposes eight connected tasks: agree on what a year’s progress means, expect every student to make that progress, develop dependable assessment and evaluation tools, understand instructional impact, ensure teachers have expertise in diagnosis and intervention, stop practices unsupported by evidence, strengthen collaboration, and communicate the profession’s collective responsibility. Variation among teachers and schools is treated as a source of information for improvement, not merely a basis for ranking. Leaders should create conditions in which educators jointly examine student work, moderate judgements, discuss evidence, learn from high-impact practice, and intervene when progress is insufficient. The report is an advocacy and synthesis document rather than a new systematic review, so its proposals depend on the quality and interpretation of the underlying evidence.
Its central idea is collective efficacy: professional autonomy should be accompanied by shared standards, transparent evidence, and collaborative responsibility for every learner’s growth.
