Chapter
The past quarter century of school leadership research has, among many other things, produced two broad claims now assumed by most of the research community to be exceptionally robust (e.g., Marzano, Waters, & McNulty, 2005; Heck & Hallinger, 2014; 2009; Robinson, Hohepa, & Lloyd, 2009): School leadership has small but significant effects on studen...
Chapter
Parent involvement in their children’s learning is widely acknowledged as having a positive effect on student academic success. Of particular relevance is the finding that the influence of parent engagement can mitigate differences in socioeconomic status (SES) and family background. Family background is a multi-dimensional concept that includes th...
Article
This paper addresses a wicked problem faced by leaders wanting to be evidence informed in their choices of school improvement priorities and the most productive leadership practices to enact in pursuing those priorities. While local contexts will always be central to these choices, results of research ought to provide useful points of departure. Bu...
Book
While considerable evidence indicates that school leaders are able to make important contributions to the success of their students, much less is known about how such contributions are made. This book provides a comprehensive account of research aimed at filling this gap in our knowledge, along with guidelines about how school leaders might use thi...

Chapter
Full-text available
The effects of leadership on student learning are largely indirect. This means that to be successful, leaders must eventually have influences on conditions that directly influence student learning. Such conditions include, for example, the quality of classroom instruction, the nature of the curriculum taught, and the disciplinary climate in the sch...
Chapter
In this article we tie together evidence drawn from several extensive reviews of the educational leadership literature that included instructional leadership as a key construct (Hallinger, 2001, 2003; Hallinger and Heck, 1996a, 1996b; Southworth, 2002). This article defines the characteristics underlying this approach to school leadership based upo...

Results of a wide-ranging review of literature, initially completed several years ago (Leithwood, Louis, Anderson, & Wahlstrom, 2004) and regularly updated, are combined with key findings from a large-scale study of leadership and student lea...
Article
There is a significant strand of theory and research about turning around underperforming organizations; however, very little of it speaks to the unique mission and character of schools. This literature is unambiguous in its claim that leadership is the pivotal explanation for success, suggesting that efforts to better understand the nature of succ...
Chapter
Current interest in distributed sources of leadership is pervasive among both researchers and practicing leaders (e.g., Harris, 2009; Hammersley-Fletcher and Brundrett, 2005; Storey, 2004). Nevertheless, systematic evidence is modest, at best, about the factors that influence the nature and extent of distributed leadership in schools, as well as th...
Article
Purpose: This study aimed to estimate the impact of collective, or shared, leadership on key teacher variables and on student achievement. As well, it inquired about the relative contribution of different sources of such leadership and whether differences among patterns of collective leadership were related to differences in student achievement. Me...
Article
Purposes: This study aimed to improve our understanding of the nature, causes and consequence of school leader efficacy, including indirect influences on student learning. We asked about district contributions to school leader efficacy, whether leader self- and collective efficacy responded to the same or different district conditions and the effec...
Article
Policy makers and leadership developers now admonish both aspiring and practicing educational leaders to base what they do on evidence of “best practice”. Some argue, however, that today’s best practices stand a reasonably good chance of being unsuitable for schools in the future. Unfortunately, effective leadership in future schools is empirically...
Article
In this paper the authors provide a synopsis of their results to date by organising them in response to four questions. These are questions about: leadership actions that account for sustained improvement or effectiveness in their school over at least several years; how the influence of these actions is exercised; differences among heads’ leadershi...

Book
The leadership of school principals is an enormously powerful influence on the quality of schools and the learning of pupils. While the work of principals has been examined intensively over the past 20 years, almost no effort has been made to understand the role from an international or cross-cultural perspective. This book contributes significantl...

Chapter
Reflecting the prevailing sentiment of the public-at-large, governments in many parts of the world show little patience for the usual pace of educational change. One of the primary reasons for this impatience is the largely uncontested link, in the minds of many policy makers, between a globally competitive national economy and the quality of a nat...

Book
The first International Handbook of Educational Leadership and Administration (Leithwood et al.) was published in 1996 and quickly became something of a best seller for reference works within education. Such success, we suggest, was at least partly due to the unprecedented global waves of concern for improving schools launched in the mid 1980's, co...

... Por ejemplo, Sun & Leithwood (2014), tras una revisión documental de 24 estudios que evaluaban efectos directos del Liderazgo Transformacional Escolar (LTE) (Kvashnina & Martynko, 2016), en el logro de los estudiantes, encuentran una relación pequeña, pero con significativo efecto positivo directo, con un coeficiente de correlación promedio de 0.09. Los autores también encuentran que algunas prácticas de LTE como "construir estructuras de colaboración" y "proporcionar consideración individualizada" hicieron contribuciones mucho más grandes en los logros de los estudiantes (r= 0.17 y r=0.15 respectivamente), que otras prácticas, las cuales oscilaron entre r= 0.03 y r= 0.05. ...
... The adoption of collaborative and network-oriented approaches to educational leadership is imperative for successfully addressing the intricate challenges that schools confront and meeting the demands of evidence-based learning practices for all students (Chestnutt et al. 2023;Leithwood et al. 2023). This approach to educational leadership underscores the significance of the network and the individual actors comprising it, as the strength and quality of the connections and relationships between network actors are necessary for effective leadership practices (Tipurić 2022). ...
... The earlier sections relating to learning-centred leadership and personalised learning have made clear the complexity of information systems required and the skills needed to interpret data and then communicate that analysis. Leaders can be expected to employ 'evidence-driven decision-making' and work is needed on developing relevant quality indicators for such things as school culture, pupil engagement and collaboration among staff (Leithwood et al 2007). The new arrangements for extended schools and the idea of successful engagement with parents suggest leaders need performance indicators beyond measures of value-added academic performance. ...
... For such expertise to be exercised in schools, there need to be strong professional communities bound by a strong sense of collective responsibility for improving student learning. Such school capacities depend on active, highly competent, and confident instructional leaders working everyday in schools with teachers to refine teaching (Leithwood, 1994; Leithwood and Prestine, 2002). At the base of such instructional leadership must lie the firm belief that all teachers are capable of delivering high quality lessons and assessment tasks. ...
... • Shared leadership that values teachers' participation in making decisions (Hord, 1997, Leithwood, Jantzi and Steinbach, 1998. ...
... The research anticipated that involving diversified evaluation subjects in the assessment of P. E. learning would lead to a more holistic and comprehensive understanding of students' experiences. The findings aligned with this expectation, demonstrating that students, parents, and the broader community contribute unique perspectives that enrich the evaluation process (Leithwood, 2021;Wang & Degol, 2016). Their involvement provided a broader view of P. E. learning, extending beyond traditional quantifiable measures. ...
... Research has found that leadership influences student achievement (Bryk et al., 2010;Fullan, 2010;Grissom et al., 2021;Leithwood & Louis, 2012b;Louis, Dretzke et al., 2010;Penlington et al., 2008;Sergiovanni, 1984). Therefore, school leaders must exercise their skills, knowledge, and beliefs (Leithwood & McCullough, 2021;Louis, Dretzke et al., 2010;Wahlstrom & Lewis, 2008) to enhance student achievement (Bryk et al., 2010;DiPaola & Tschannen-Moran, 2003). What they choose to do intentionally is referred to as "leadership agency" (Bandura, 2006). ...
... In a broader sense, it refers to all procedures that lead to student learning, including managerial behaviors (Hallinger, 2013). Leithwood et al. (2020) posit that instructional leadership theoretically encapsulates all that a principal does during the day to support the achievement of students and teachers. Hallinger (2000) and Kwan (2011) suggest that defining the school's mission and framing and communicating the school's goals are the principal's responsibilities. ...
... Also, when it comes to local education authorities (LEAs), earlier research offers important insights into how successful LEAs operate and support school managers in various contexts (see, e.g. Anderson and Daly, 2013;Leithwood, 2010;Leithwood et al., 2019;Liljenberg et al., 2022;Nordholm, 2016;Rorrer et al., 2008). However, less attention has been paid to the level above the LEA level, i.e. the level of the national school agency (i.e. the Swedish National Agency for Education -SNAE). ...
... It became a foundational building block for a culture of continuous improvement that encouraged the development of school norms that support an openness to change in the direction of the purpose or vision of the school. The content and clarity of a principal's vision has been linked to educational reform efforts as well as student outcomes and is consistent with an array of relevant and well-established works in the literature on successful school leadership, including studies of the ISSPP [14][15][16]. ...
