For more than four decades, researchers, policymakers, professional educators, and the philanthropic community in education have wrestled with how to scale up promising pockets of reform. Centering equity in scaling efforts means working with and prioritizing students who have historically lacked access to powerful learning opportunities,…

Scaling in educational settings has tended to focus on replication of external programs with less focus on the nature of adaptation. In this article, we explore the scaling of Personalization for Academic and Social-emotional Learning (PASL), a systemic high school reform effort that was intentionally identified, developed, and implemented with…

Persistently large achievement gaps between high-social-class and low-social-class children in America, and the disparities in opportunity that drive these achievement gaps, threaten the very notion of the American Dream. The lack of true equality of opportunity calls for much more comprehensive interventions to tackle those gaps. This report…

This study defines subpopulation item parameter drift (SIPD) as a change in item parameters over time that is dependent on subpopulations of examinees, and hypothesizes that the presence of SIPD in anchor items is associated with bias and/or lack of invariance in three psychometric outcomes. Results show that SIPD in anchor items is associated…

Scaling in educational settings has tended to focus on replication of external programs with less focus on the nature of adaptation. In this article, we explore the scaling of Personalization for Academic and Social-emotional Learning (PASL), a systemic high school reform effort that was intentionally identified, developed, and implemented with…

This report provides a description of the development process, field testing, and psychometric properties of the fall 2015 grades 3-5 Elementary Mathematics Student Assessment (EMSA), a student mathematics test designed to be administered in a whole-group setting to students in grades 3, 4, and 5. The test was administered to 2,614 participating…

It is a truism of American social policy that our nation has great success generating innovative programs that improve outcomes for participants--but that we are far less effective at moving from small, "boutique" programs into broadly applied solutions that improve the prospects of large numbers of individuals. This is certainly true in…

This study examines the use of cross-classified random effects models (CCrem) and cross-classified multiple membership random effects models (CCMMrem) to model rater bias and estimate teacher effectiveness. Effect estimates are compared using CTT versus item response theory (IRT) scaling methods and three models (i.e., conventional multilevel…

This is the first in a series of Business-Higher Education Forum (BHEF) playbooks intended to assist companies, higher education institutions, private philanthropies, membership associations, professional societies, government agencies, and other stakeholders seeking to understand the potential value of investing in coordinated strategic,…

The release of School Grades by the State of Florida in the late summer of 2010 created quite a stir. Over 500 elementary schools all over the state dropped at least one grade level. Among those schools that experienced drops, the Reading Gains and Mathematics Gains components seemed especially low. Some of the historically best performing schools…

A vertical scale, in principle, provides a common metric across tests with differing difficulties (e.g., spanning multiple grades) so that statements of "absolute" growth can be made. This paper compares 16 states' 2007-2008 effect size growth trends on vertically scaled reading and math assessments across grades 3 to 8. Two patterns…

This study investigated the psychometrics of the "Diagnostic Evaluation of Language Variation-Screening Test" (DELV-S) test using confirmatory factor analysis, item response theory, and differential item functioning (DIF). Responses from 1,764 students in kindergarten through second grade were used in the study, with results indicating…

The core work of the National Center on Scaling Up Effective Schools consists of four stages: identifying practices of highly effective high schools, designing interventions and transfer of practices, evaluating the intervention's implementation and effects, and evaluating implementation at scale. The purpose of this report is to describe the…

Rasch measurement can provide a much needed solution to scaling teacher ability. Typically, decisions about teacher ability are based on dichotomously scored certification tests focused on knowledge of content or pedagogy. This paper presents early developmental work of a partial credit teacher ability scale of 42 tasks (performances and…
