As countries make continued investments in early childhood care and education (ECCE) systems, data and measurement play a critical role in outlining strengths and areas for improvement. To promote data-driven decision-making across all levels of early childhood systems, measurement must be valid, reliable, and feasible, especially when used at…

Both 'collegiality' and 'distributed leadership' have, as terms, occasioned a good deal of debate. Conceptually elastic, they are often used interchangeably, or not appreciated as embodying a range of leadership styles and relationships. Spurred by an unanswered query from a research project, this theoretical article attempts to clarify what the…

The study of educational leadership suffers from a lack of precision in definition of key concepts (Modeste et al., 2020; Wang, 2018). This is particularly true for teacher leadership (Wenner & Campbell, 2017) where the core leadership practices that teacher leaders engage in are collaborative in nature and take many forms, including mentoring…

Focussing on teachers' subject pedagogical actions over the course of a series of lessons on a mathematical topic, this paper sets out an original analytical approach to characterise the shape of mathematics teaching decisions made over time: tri-polar analysis. The notion of manifestation is introduced as a way of categorising how the teacher is…

The COVID-19 pandemic has disrupted some traditional assessment practices and drawn attention to the range of evidence students produce in their day-to-day learning. In this edition of Assessment News, Charles Darr and Rosemary Hipkins argue that using this evidence to make sound summative judgements requires a robust understanding of what it…

Increasing instructional quality in higher education is a key goal of educational development (ED) work, yet demonstrating complex outcomes remains challenging and lacks practical guidance. Evaluating ED services often relies on a reductionist approach characterized by linear assumptions of causal pathways to measure the extent to which…

More students are learning online than ever before, and while researchers have demonstrated that learning online can be as or more effective than learning onsite, there are challenges for students in online courses, including feelings of isolation. Intentionally planning for and supporting community in online courses can help overcome these…

In this paper, we draw upon in-depth interviews with teachers and administrators in 18 unionized charter schools around the country to investigate teachers' motivations for unionization. Our results suggest that while mismanagement and distrust are often the proximate cause of charter unionization efforts, both material and purposive…

This review has looked at how to maximise the difference that academy trusts can make to children's lives, so all children can fulfil their potential, through a focus on trust quality and improved system resilience. High-quality trusts deliver for children in their schools and in their wider communities, as civic institutions acting in the public…

The papers in the special series describe the role of data-based decision-making (DBDM) in improving the outcomes of students with learning disabilities based on research across Germany, the Netherlands, and the United States. The articles address multiple aspects of a model of DBDM that includes the role of teacher knowledge, skills, beliefs, and…

An increasing number of high schools have adopted Tier 1 PBIS; however, implementation of advanced tiers of PBIS in high schools is less common and specific guidance is scarce. To address this need and better understand the level of support needed to successfully implement advanced tiers of PBIS at the high school level, the National Center on…

The collection and use of empirical data for educational decision-making in the United States is required by the Every School Succeeds Act (ESSA) and the Results Driven Accountability mandate, but there is insufficient data available for one population, in particular: refugee, asylee, and humanitarian migrant (RAHM) students. As a result, the…

The language assessment literacy of English language teachers has been one of the topics of discussion in the language testing field. In this article, I focus on the need to expand research constructs and methodologies to understand, in depth, the language assessment literacy for these key players in language assessment. I first explain the need…

With the proliferation of video-based professional development (PD) courses for mathematics teachers, understanding the role of the facilitators of these courses has become an emerging field of theoretical and empirical study. The purpose of this article is to address some of the challenges and opportunities that facilitation of discussions…

Drawing on the capability approach to human development and Bourdieuan reflexive sociology, this paper explores the interplay of teacher agency and professional practice. The paper names five facets of teacher agency. It shows that teachers with a strong sense of agency actively seek learning opportunities--inquisitive agency; think effortfully…
