“…The causality belief is often deployed by mainstream educational leadership researchers as a rationale for examining, and the departure point for presenting findings on, the work of educational institutions’ senior management post-holders, such as headteachers and principals, as illustrated by the following statements – all appearing in the abstracts or opening paragraphs of articles in specialist educational leadership, management and administration journals: ‘School leaders are essential to the success of schools’ (Anderson et al, 2020: 1); ‘School principals play an invaluable role in schools’, teachers’, and students’ success’ (Woong Lee and Mao, 2020: 1); ‘Effective school leadership is a critical aspect to improve the quality of education.

As their dates of publication show, such statements indicate the causality belief to remain, ostensibly at least, alive and kicking in the third decade of the 21st century, and evidently resilient in the face of extensive criticism (outlined below) that has accumulated over the last five decades of educational leadership scholarship.…”
