A fundamental premise in assessment is that the underlying construct is equivalent across different groups of students and that this structure does not vary over years. The pandemic has potentially impacted opportunity to learn and disrupted the internal structure of assessments in various ways. Past research has suggested that students tended to…

Head Start is a national program that helps young children from families with low income get ready to succeed in school. It does this by working to promote their early learning and health and their families' well-being. The Head Start Family and Child Experiences Survey (FACES) provides national information about Head Start programs and…

The impact of misspecifying covariance matrices at the second and third levels of the three-level model is evaluated. Results indicate that ignoring existing covariance has no effect on the treatment effect estimate. In addition, the between-case variance estimates are unbiased when covariance is either modeled or ignored. If the research interest…

Proactive preliminary minimum sample size determination can be useful for the early planning stages of a latent variable modeling study to set a realistic scope, long before the model and population are finalized. This study examined existing methods and proposed a new method for proactive preliminary minimum sample size determination.

Evaluators of education interventions are increasingly designing studies to detect impacts much smaller than the 0.20 standard deviations that Cohen (1988) characterized as "small." While the need to detect smaller impacts is based on compelling arguments that such impacts are substantively meaningful, the drive to detect smaller impacts…

This study investigates the psychometric properties of the Romanian version of the Dyadic Coping Inventory with data from 510 married couples. The results confirm the theoretical factorial structure of the Dyadic Coping Inventory for both partners, indicating convergent validity, discriminate validity, and measurement invariance (across genders…

This year signifies two key milestones in the GradNation campaign to raise high school graduation rates. First, the release of the 2015 federal graduation rate data marks five years since states began reporting the Adjusted Cohort Graduation Rate (ACGR). The ACGR, for the first time, created a common formula for collecting graduation rate…

A valuable extension of the single-rating regression discontinuity design (RDD) is a multiple-rating RDD (MRRDD). To date, four main methods have been used to estimate average treatment effects at the multiple treatment frontiers of an MRRDD: the "surface" method, the "frontier" method, the "binding-score" method, and…

The Education Longitudinal Study of 2002 (ELS:2002) tracks the educational and developmental experiences of a nationally representative sample of United States high school students who were sophomores in the spring of 2002. This First Look report provides a descriptive portrait of their postsecondary education experiences through the end of the…

The purpose of this report is to describe the procedure for revising the ReadiStep™ score scale using the field trial data, and to provide technical information about the development of the new ReadiStep scale score. In doing so, this report briefly introduces the three assessments--ReadiStep, PSAT/NMSQT®, and SAT®--in the College Board Pathway…

This report presents selected findings from the Public School Principal Status and Private School Principal Status Data Files of the 2012-13 Principal Follow-up Survey (PFS). The PFS is a nationally representative sample survey of public and private K-12 schools in the 50 states and District of Columbia and was initiated to inform discussions and…

This revised data file includes corrections that were provided to NCES as a result of a special collection effort designed to address data quality issues found in the 1a release of this file. In May 2012, NCES became aware of data errors for key data items for several schools on the published version of the SY 2009-10 school file; in some cases…

The IDEA Feedback for Administrators system provides feedback to academic administrators about their performance of relevant administrative responsibilities and their leadership style and interpersonal characteristics. The system is based on a model of reflective practice, which is consistent with The IDEA Center's longstanding approach to…

This report examines the differences in impact estimates and standard errors that arise when these are derived using state achievement tests only (as pre-tests and post-tests), study-administered tests only, or some combination of state- and study-administered tests. State tests may yield different evaluation results relative to a test that is…

Student victimization in schools is a major concern of educators, policymakers, administrators, parents, and students. Understanding the scope of the criminal victimization of students, as well as the factors associated with it, is an essential step in developing solutions to address the issues of school crime and violence. This report uses data…
