Research-practice partnerships are collaborative research arrangements that seek to transform the relations among researchers, educators, and communities. There is a wide diversity in partnership forms and research methods used in them. In addition, there remain questions about the value of partnerships, given the time and resources they require…

Although experimental evaluations have been labeled the "gold standard" of evidence for policy (U.S. Department of Education, 2003), evaluations without an analysis of costs are not sufficient for policymaking (Monk, 1995; Ross et al., 2007). Funding organizations now require cost-effectiveness data in most evaluations of effects. Yet,…

Lottery-based identification strategies offer potential for generating the next generation of evidence on U.S. early education programs. The authors' collaborative network of five research teams applying this design in early education settings and methods experts has identified six challenges that need to be carefully considered in this next…

Though there is widespread recognition of the importance of implementation research, evaluators often face intense logistical, budgetary, and methodological challenges in their efforts to assess intervention implementation in the field. This article proposes a set of natural language processing techniques called semantic similarity as an…

Among all the factors that influence the success of preschool programs, none is more important than the quality of the teaching workforce. The design and delivery of effective approaches to professional development (PD) are central to the support of the early childhood education workforce. In this article, we provide a model outlining the PD…

Five years into the Common Core initiative, researchers and the general public are interested to know whether and how the standards are "working." In this introduction to the special topic, I discuss the state of the literature on these questions and offer suggestions for what I view as the most important work moving forward.

Almost every state-level Quality Rating and Improvement System (QRIS) in the country includes family engagement as an indicator of early childhood education quality. Yet, most QRIS measure family engagement using a uniform, narrow set of parent involvement activities at the center. We propose an alternative approach that emphasizes a range of…

Recent attention on partnerships between researchers and practitioners highlights the potential of these relationships to provide high-quality usable knowledge for improving schools. But how do we translate guiding partnership principles into specific actionable steps? How do we build and maintain an effective partnership? How do we reconcile and…

Forty years ago, the National Center for Education Statistics initiated the national longitudinal studies program in response to congressional concern for policy-relevant information on school-to-work transitions. This program has grown substantially, and not unexpectedly, questions have arisen about its usefulness and present operation. This…

The introduction to this Special Topic Collection has two parts. To provide background and context for the articles in the collection, Part 1 tells the story of the Early Childhood Longitudinal Study program at the National Center for Education Statistics. It offers an abridged history of this program and describes the designs of the two national…
