Overview

                 Retaining more teachers is crucial for the education system when there are not
                 enough teachers coming in to the profession to meet the growing need from rising
                 pupil numbers. Unmanageable workload and low job satisfaction are significant
                 factors determining teachers’ decision to stay in the profession or leave.

                 Our research is the first large-scale quantitative   School leaders and the Department for Education
                 study to look at teacher autonomy and its            should consider how to adapt policy and

                 profession. We also find that the average teacher
                 has a lower level of autonomy compared to
                 similar professionals.

                 Teachers’ autonomy over their professional
                 development goal-setting is particularly low,
                 and is the most associated with higher job
                 satisfaction. Increasing teachers’ autonomy,
                 particularly over their professional development
                 goals, therefore has great potential for
                 improving teacher job satisfaction and retention.

1   By autonomy, we mean the capacity to make informed decisions and/or act independently. The term ‘agency’ is also used in the research literature to refer to a similar, although
    not identical, concept. Another occasionally used term is ‘job control’ (see for example, Bryson et al., 2019). We use the term ‘autonomy’, following the convention used by
    self‑determination theory (Deci and Ryan, 2008) and the Taylor Review of Modern Working Practices (HM Government, 2018).

8    We use the term ‘professional development’ to mean activities that teachers engage in to develop and enhance their teaching abilities, after having completed initial teacher training or
     education. The research literature uses a range of terms with subtle differences in definition, such as continuing professional development (CPD), professional learning (PL). We use PD
     as a catchall term for these concepts, as the subtle distinctions between the various terms are not relevant for interpreting these findings.
