Drawing on data from 116 survey responses by School Business Managers, and 7 semi-structured interviews with education professionals carried out between October 2017 and February 2018, this article reports on findings from a research project focussing on the opportunities and constraints for career progression into leadership roles for School Business Managers (SBMs) in the state sector in England. The article considers the differing roles and responsibilities of SBMs, how leadership is perceived in schools, the visibility of the SBM role, career aspirations of the SBMs who were surveyed, and the perceived constraints to progression to leadership roles. Analysis of the data was carried out using an inductive research approach using mixed methods. Snowballing was used to obtain a meaningful sample size for survey responses. Interviewees were chosen on the basis of judgement sampling. The sampling design for the survey and the interviews was one of non-probability. Findings suggest that leadership roles for SBMs do exist but that there are considerable constraints to these being achieved, not least the lack of appetite amongst SBMs to do so.
