This study reports achievement and growth from kindergarten to 4th grade for three groups of English Learners. The findings suggest summer support is required to help ELs maintain and develop academic skills.

This study presents a statistical model motivated by the seasonal character of interim achievement data and analyses aimed at reducing barriers to the generation of empirical benchmarks for repeated measures achievement data.

This report documents the results of an item parameter drift study designed to check the parameter stability of MAP Growth items.

The COVID-19 pandemic, coupled with political and social unrest, has deeply disrupted the lives and learning experiences of most students. It has created an urgent need to address long-standing opportunity gaps and has highlighted the importance of providing resources that support student achievement, social-emotional learning, and physical and mental well-being. This urgency for action to address the impacts is valid, but it has also created a noisy environment of potential options of what might be best for students. It’s critical, now more than ever, for decisions to be grounded in solid research.

School officials regularly use school-aggregate test scores to monitor school performance and make policy decisions. In this report, RAND researchers investigate one specific issue that may contaminate utilization of COVID-19–era school-aggregate scores and result in faulty comparisons with historical and other proximal aggregate scores: changes in school composition over time. To investigate this issue, they examine data from NWEA’s MAP Growth assessments, interim assessments used by states and districts during the 2020–2021 school year.

Students with disabilities lose even more ground than peers during summer and other interruptions in their learning—but they don’t need to. Data point to a need for services that extend beyond the school year.

To what extent has the COVID-19 pandemic affected student achievement and growth in reading and math, and which students have been most affected? Using data from 6 million students in grades 3-8 who took MAP Growth assessments in reading and math, this brief examines how gains across the pandemic (fall 2019 to fall 2021) and student achievement in fall 2021 compare to pre-pandemic trends. This research provides insight to leaders working to support recovery.
