This research brief explores the relationship between how students responded to a survey about their math experiences and mindsets and how they performed on an end-of-year state standardized math assessment. For this study, NORC partnered with a racially diverse school district in the northeastern region of the United States. Educators in the district learned about NORC's Youth and Teen Math Mindset study (funded by the Bill and Melina Gates Foundation) and expressed interest in administering NORC's survey to get a better sense of what factors may underlie and influence students' math achievement. Together, NORC and the district administered the survey in the spring of the 2022-2023 academic year to students in the fourth through tenth grades.
