Most of the world is multilingual--multilingual at the national level (policies), at the community and family level (practices), and at the individual level (cognitive)--and each of these has implications for teaching and learning. Yet, at present, most reading decisions are not based on empirical research of how children learn to read in…

The purpose of this study is to evaluate the implementation and impacts of the Building Assets, Reducing Risks (BARR) model in its first year of implementation in 66 schools across the U.S. and to document scale-up progress during the Investing in Innovation (i3) grant period (2017-2021). The impact evaluation included 21,529 9th grade students…

The present study was commissioned by the Massachusetts Department of Elementary and Secondary Education (ESE) to provide a profile of Massachusetts English Language Learners (ELLs) and policy recommendations for improving their outcomes. ESE was concerned about previous study findings that most of these learners exited ELL instructional programs…

This report uses international benchmarking as a common metric to examine and compare what students are expected to learn in some states with what students are expected to learn in other states. The performance standards in each state were compared with the international benchmarks used in two international assessments, and it was assumed that…

California's Kindergarten Readiness Act of 2010 established transitional kindergarten (TK), the first year of a two-year kindergarten program for students affected by the change in the birthdate cutoff for entry into kindergarten from December 2 to September 1. This final report from the program's evaluation focuses on results from a five-year…

The objectives of this research are to (a) compare the trend lines after some adjustments for level and scale only and determine if and how they differ; (b) describe the methodology of each assessment and identify similarities and differences; and (c) attempt to explain any observed differences based on comparable subsets or on special analysis.…

In 2010, Governor Arnold Schwarzenegger signed the Kindergarten Readiness Act into law, which changed the kindergarten entry age so that children must turn 5 by September instead of December to enroll. The new grade level was put into place to promote school readiness for California's youngest learners. It also established a new grade…

Fundamental to statistical analyses is the comparison of means of one variable from two or more populations. Population samples may be constructed (i.e., experimental and control groups), or they may be natural groupings (i.e., students at a particular grade in different years). If the populations are similar, the mean comparisons are…

The NAEP Validity Studies (NVS) Panel provides advice and recommendations to help insure the "validity" of the National Assessment of Educational Progress (NAEP) test scores. The primary objectives of NAEP tests are to accurately monitor the progress of defined groups of students over time and to measure valid differences in scores…

This report outlines several critical issues that should be addressed in order to allow states to explore and understand relationships between the performance of ELL students on NAEP and on state assessments in this policy context. The results of this study can be useful to a variety of education stakeholders who are interested in improving the…

Because NAEP estimates of state-level achievement play an important role in the evaluation of strategies for improving the nation's educational system, it is important that these estimates have as small a standard error as possible. NAEP estimates for state-level achievement are based on measurement of the performance of a random sample of…

A simulation study was conducted to explore the potential of state assessment scores to improve adjustments for nonparticipation (McLaughlin, Gallagher, and Stancavage, 2004). That study found that state assessment scores could potentially be more effective than demographic information in removing the bias related to absences. The present study…

Under the federal Individuals with Disabilities Education Act (IDEA), school districts are required to meet the educational needs of all students with disabilities. However, school districts struggle to provide adequate services to students with disabilities who have extraordinary needs and require unusually high expenditures to meet those…

Rapid changes in technology make it necessary for adults of all ages to use written information in new and more complex ways. For example, learning how to operate computers, filling out complicated tax forms, and comparing price labels when shopping for groceries are just a few of the many tasks that are important parts of peoples lives. Every…
