The purpose of this report is to present a synthesis of the research on test accommodations for U.S. elementary and secondary students (K-12) published in 2018. The academic literature described here encompasses empirical studies of performance comparability, investigations into accommodations use, implementation practices, and perceptions of the…

Students living in poverty tend to perform worse in school than their peers from better-off families. This paper examines whether computer availability helps narrow down educational inequalities in Slovakia, using TIMSS and PIRLS data. The results show that computer availability in reading lessons improves reading scores and that the effect is…

Background: Students vary in their initial achievement when they enter school and their rate of academic growth as they move through school. These differences have implications for classroom instruction and educational policy. Although previous research has examined initial achievement and growth differences, a gap remains in understanding how…

Researchers explored how 13 states in which policymakers have adopted an A-F school letter grade accountability system performed on the National Assessment of Educational Progress (NAEP) post-policy implementation. Researchers found mixed results, with approximately half of these 13 states increasing achievement post-policy, and the other…

The 2015 reauthorization of the Every Student Succeeds Act (ESSA) placed a state-level 1.0% threshold on student participation in the alternate assessment based on alternate academic achievement standard (AA-AAAS). ESSA also stipulated that state education agencies (SEAs) may not impose on any local educational agency (LEA) a cap on the percentage…

This study analyzed the relationship between benchmark scores from the newly published Dynamic Indicators of Basic Early Literacy Skills Math (i.e., Acadience™) math probes and student performance on math and reading sections of a state-mandated high-stakes test. Participants were 420 students enrolled in third, fourth, and fifth grades in a rural…

This "Guide" is an update to the State Guide to Universally Designed Assessments produced by the National Center on Educational Outcomes (NCEO) in 2006 (Johnstone et al.). It provides a brief overview of what a universally designed assessment is, followed by a set of steps for states to consider when designing and developing, or…

The student population throughout the United States has shifted; thus, it is essential to consider ways to address the needs of culturally, linguistically diverse (CLD) students. Prior research found that culturally relevant teaching (CRT) improves academic performance. However, little quantitative research examines the relationship between CRT…

Under the Individuals with Disabilities Education Act, schools are required to provide a free appropriate public education to students with disabilities and show that the students are making academic progress. This study compares within- and across-years academic growth from kindergarten to 4th grade for students who were ever in special education…

The present longitudinal study investigated the developmental trajectories of addition, subtraction, and multiplication fluency; their relationships to general cognitive functions; and potential interrelations between reading fluency and growth in arithmetic fluency for different operations. The central prediction was that measures of arithmetic…

Scientific reasoning is an important skill that encompasses hypothesizing, experimenting, inferencing, evaluating data and drawing conclusions. Previous research found consistent inter- and intra-individual differences in children's ability to perform these component skills, which are still largely unaccounted for. This study examined these…

Speeded tests set time limits so that few examinees can reach all items, and power tests allow most test-takers sufficient time to attempt all items. Educational achievement tests are sometimes described as "timed power tests" because the amount of time provided is intended to allow nearly all students to complete the test, yet this…

During the Spring 2020 semester, all fifty states in the United States closed schools from in-person instruction due to the COVID-19 global pandemic. When the two Upstate South Carolina school districts in this study reopened in the Fall of 2020, they gave families the option of allowing students to attend newly developed virtual schools which…

Reading comprehension skill is seen as a predictor of word problem-solving performance, and the close relationship between reading comprehension and mathematical skills is accentuated. On the other hand, more research is needed as to determine how logical thinking and word problem solving are related to each other and to analyze the role of…

The "5Essentials Survey" is one of the few validated instruments to measure school climate. Schools that are strong in at least three of the five essential supports are up to 10 times more likely to experience substantial gains in students' math and reading scores. More than 6,000 schools nationwide have administered the…
