Although Montessori is the most common unconventional education model, no multi-state study has compared standardized test proficiency of Montessori schools with districts. Here we report on this for the 10 states/regions with the most public Montessori schools (n = 195). In 3rd grade, Montessori schools were less proficient in math but more…

The purpose of this technical appendix is to share detailed results and more fully describe the sample and methods used to produce the research brief, "COVID's Impact on Science Achievement: Trends from 2019 through 2024. We investigated three main research questions in this brief: 1) How did science achievement in 2021 and 2024 compare to…

This brief continues ongoing research by NWEA® examining the degree to which the COVID-19 pandemic, and its associated school closures, influenced student learning.

The research featured in this paper is part of the CORE-PACE Research Partnership, which is focused on producing research that informs continuous improvement in the CORE districts as well as policy and practice in California and beyond. In this report, the authors used data from multiple interim assessments to examine how the rate of student…

As the U.S. population has become increasingly diverse--a continuing trend led by children--there has been an accompanying rise in the number of children who grow up hearing and learning more than one language.

We studied developmental trends in 5 important reasoning tasks that are critical components of the operational definition of rational thinking. The tasks measured denominator neglect, belief bias, base rate sensitivity, resistance to framing, and the tendency toward otherside thinking. In addition to age, we examined 2 other individual difference…

This study describes enrollment and achievement trends of limited English proficient (LEP) students in New Jersey public schools between 2002/03 and 2008/09. It documents achievement gaps between LEP and general education students in language arts literacy and math. The study's main findings include: (1) From 2002/03 to 2008/09, LEP student…

This report compares state math and reading proficiency scores in grades 4 and 8 to National Assessment of Educational Progress (NAEP) basic scores for the period of 2005 to 2009. The study found that scores on state tests and NAEP have increased in most states with sufficient data. Also included with the report are profiles for the 23 states that…

This study describes English language learner (ELL) student enrollment and achievement trends in Delaware public schools from 2002/03 to 2008/09. Two research questions guide this study: (1) How did the enrollment of ELL students in Delaware public schools change between 2002/03 and 2008/09?; and (2) How did performance (the percentage scoring at…
