Decision Making in For School Leaders: Best Practices for Headteachers
Over the last 10 years, the role of headteachers has become increasingly complex. Effective decision-making is at the heart of successful school leadership, requiring analytical thinking, emotional intelligence, and strategic foresight. In this article, we explore the best practices for headteachers in making informed decisions and examples of how these practices can be applied in school settings.

Understanding the Context
The first step in effective decision-making is understanding the context in which decisions are made. This includes recognising the unique characteristics of the school, such as its demographic makeup, community values, and institutional goals, values and stories. According to recent studies, successful school leaders tailor their leadership strategies to their specific school context, demonstrating an ability to respond to the needs and motivations of others. This contextual awareness allows headteachers to make decisions that are not only relevant but also impactful.
Data-Driven Decision Making
One of the cornerstones of effective decision-making is the use of data. Headteachers must be committed to data-based decision-making, as this approach provides a solid foundation for evaluating the effectiveness of various initiatives and interventions. For instance, a study highlighted that a clear focus on pupil learning and achievement, supported by data, significantly influences school leaders’ sense of efficacy and, consequently, their leadership practices.
To illustrate, let’s consider a headteacher who is looking to improve literacy rates in their school. The headteacher can identify specific areas where students are struggling by analysing data from standardised tests, classroom assessments, and reading logs. This information can then inform targeted interventions, such as after-school reading programmes or professional development for teachers on literacy instruction.
Collaborative Decision-Making
Effective decision-making in schools often involves collaboration. Headteachers should foster a culture of partnership and teamwork, engaging staff, students, and parents in the decision-making process. This approach brings diverse perspectives and a sense of ownership and commitment to the outcomes.
For example, when considering the implementation of a new curriculum, a headteacher might form a committee comprising teachers from various departments, parents, and even students. By doing so, the headteacher ensures that the decision is well-rounded and takes into account the views and needs of all stakeholders. This collaborative approach was exemplified in a case study where school leaders worked closely with the SENCo and class teachers to evaluate the effectiveness of interventions and share the results with the wider school community.
Ethical and Moral Considerations
The foundation of effective decision-making lies in a strong moral and ethical compass. Headteachers must ensure that their decisions align with the core values of equity, social justice, and inclusivity. These values should guide every decision, from resource allocation to disciplinary actions.
An illustrative example is a headteacher who is deciding how to allocate funds for extracurricular activities. By prioritising programmes that promote inclusivity and provide opportunities for all students, regardless of their socio-economic background, the headteacher demonstrates a commitment to social justice. This approach not only enriches the school culture but also ensures that all students have access to a well-rounded education.
Strategic Planning
Strategic planning is integral to effective decision-making. Headteachers must be adept at setting long-term goals and developing a roadmap. This involves not only identifying priorities but also allocating resources and monitoring progress.
For instance, a headteacher aiming to enhance STEM education in their school might start by setting a goal to improve student performance in these subjects. The next steps could include investing in professional development for teachers, upgrading laboratory facilities, and creating partnerships with local universities and industries. By strategically planning these initiatives, the headteacher ensures that each decision is aligned with the overarching goal.
Flexibility and Adaptability
In the ever-changing landscape of education, headteachers must be flexible and adaptable. This means being open to new ideas and ready to pivot when necessary. Flexibility is particularly crucial when faced with unforeseen challenges or when initial plans do not yield the expected results.
A pertinent example is the rapid shift to remote learning during the COVID-19 pandemic. Headteachers who were able to quickly adapt to this new mode of instruction, by leveraging technology and supporting teachers and students, were better positioned to minimise disruptions to learning. Their ability to remain flexible and responsive in the face of unprecedented challenges underscores the importance of adaptability in school leadership.
When implementing interventions, headteachers should rely on evidence-based strategies. This involves reviewing research and evaluating the effectiveness of different approaches before adopting them. For instance, a meta-analysis by Robinson et al. (2009) identified specific leadership practices that significantly contribute to school improvement, such as promoting and participating in teacher training, and managing strategic resources. By focusing on proven methods, headteachers can ensure that their interventions are both effective and sustainable.

Personal Anecdote: The Great Technology Debate
Allow me to share a personal anecdote from my time as a headteacher. We once faced a decision about whether to invest in new technology for our classrooms. The staff were divided; some were enthusiastic about the potential benefits, while others were concerned about the cost and the learning curve.
To make an informed decision, we formed a committee that included teachers, IT experts, and even a few tech-savvy students. We conducted a pilot programme in a few classrooms, gathered data on its impact, and held several meetings to discuss our findings. Ultimately, the data showed significant improvements in student engagement and achievement, which convinced even the sceptics. This collaborative and data-driven approach led to a successful implementation and strengthened our school community.
