This Statistics in Brief (SiB) uses data from the 2011 and 2019 Trends in International Mathematics and Science Study (TIMSS), and explores how achievement gaps between high- and low-performing 4th- and 8th-grade students in the U.S. and other education systems have changed over time. Achievement gaps are defined as the differences in scores…

The purpose of this technical appendix is to share more detailed results and to describe more fully the sample and methods used in the research included in the brief, "The Widening Achievement Divide during COVID-19." The authors investigated two main research questions in this brief: (1) To what degree have students' reading and math…

This volume of PISA examines the readiness of students to engage with learning strategies, to be motivated to learn and to be confident in their abilities and in their capacity to improve their skills and knowledge. Countries like Korea have reduced mathematics anxiety, Portugal excels in critical thinking, and more low-performing students in…

The Trends in International Mathematics and Science Study (TIMSS) is an international comparative study that measures trends in mathematics and science achievement at the 4th and 8th grades every 4 years. TIMSS is designed to align broadly with mathematics and science curricula in the participating education systems and, therefore, to reflect…

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…

Although low performers should invest more time and effort in their studies, they seldom do. One reason is because they often feel that they get no return on their investment: more studying does not automatically lead to better marks in school. But with the right kind of in-school support, including creative and engaging mathematics-related…

Socio-economically advantaged and disadvantaged students are not equally exposed to mathematics problems and concepts at school. Exposure to mathematics at school has an impact on performance, and disadvantaged students' relative lack of familiarity with mathematics partly explains their lower performance. Widening access to mathematics content…

The OECD Programme for International Student Assessment (PISA) examines not just what students know in science, reading and mathematics, but what they can do with what they know. Results from PISA show educators and policy makers the quality and equity of learning outcomes achieved elsewhere, and allow them to learn from the policies and practices…

The OECD Programme for International Student Assessment (PISA) examines what students know in reading, mathematics and science, and what they can do with what they know. It provides the most comprehensive and rigorous international assessment of student learning outcomes to date. Results from PISA indicate the quality and equity of learning…

The release of the latest results of the Programme for International Student Assessment (PISA) garnered all the usual headlines about America's lackluster performance and the rise of competitor nations. To be sure, the findings--that America's fifteen-year-olds perform in the middle of the pack in both reading and math--are disconcerting for a…

Summarizes results from a larger report identifying both school and individual variables related to the test score decline of the 1970s. Public awareness of the relationship between changes in student and school variables and score decline will help prevent another national educational deficit of this type. (LHW)

This paper highlights the results of analysis of achievement trends, described in report "Changes in Student Performance by Achievement Class and Model Class." This paper extrapolates from the complete study those findings that have the most direct implications for education policy and decision makers. Overall, students in the lowest…

An overview of results from the National Assessment of Educational Progress in reading, science, and mathematics for American students during the 1970's -- ages 9, 13, and 17 -- is presented. Results are for three learning areas commonly accepted as critical to the maintenance of our increasingly technological society. Data on performance have…

ExceL grants are a local funding initiative of the Austin Independent School District (Texas) designed to improve student achievement at the elementary level. Schools submit proposals for the 4-year grants, and the amount of the grant is determined based on the number of students not meeting minimum expectations on the Texas Assessment of Academic…

This year the Center on Education Policy (CEP) analyzed data on the achievement of different groups of students in two distinct ways. First, it looked at grade 4 test results to determine whether the performance of various groups improved at three achievement levels--basic and above, proficient and above, and advanced. Second, it looked at gaps…
