This volume provides a succinct up-to-date summary of global research on principal instructional leadership as it has evolved over the past 50 years. The book’s particular focus is on the development and use of the Principal Instructional Management Rating Scale (PIMRS). The PIMRS is the most widely used survey instrument designed for assessing instructional leadership for research and practice. It has been used in more than 250 studies in more than 30 countries around the world. The authors provide a detailed conceptual and data-based description of the rationale and development of the instrument as well as the ways in which it has been used in practice. The book also provides, for the first time, a comprehensive assessment of the scale’s measurement properties. This represents essential information for future users of the instrument across different national contexts. Finally, the volume outlines an agenda for improving future research on the role of principal instructional leadership in student learning and school effectiveness.

This book focuses on the effect of leadership on organizational outcomes and summarizes the current research findings in the field. It addresses the need for inclusive and interpretive studies in the field in order to interpret leadership literature and suggest new pathways for further studies. Appropriately, a meta-analysis approach is used by the contributors to show the big picture to the researchers by analyzing and combining the findings from different independent studies. In particular, the editors compile various studies examining the relationship between the leadership and thirteen organizational outcomes separately. The philosophy behind this book is to direct future research and practices rather than addressing the limits of current studies.

Over the last decade, the educational context for students with disabilities has significantly changed primarily as a result of mandates contained in NCLB and IDEA. The purpose of this book is to summarize the research literature regarding how students might be provided classrooms and schools that are both inclusive and effective. Inclusive schools are defined as places where students with disabilities are valued and active participants in academic and social activities and are given supports that help them succeed. Effectiveness is addressed within the current movement toward multi-tiered systems of support and evidence-based practices that meet the demands of high-stakes accountability.
