Where students live and their background shape their educational experience. This project explores how the COVID-19 pandemic impacted educational outcomes and various demographic subgroups in California and Ohio.

The COVID-19 pandemic was an unprecedented global event that profoundly impacted education systems worldwide. In the United States, school closures forced a shift to remote and hybrid learning—a challenge that was unfamiliar to both students and educators. Even before the pandemic, students from low-income families and communities of color already faced pre-existing achievement gaps. However, COVID-19 further exacerbated these disparities, as under-resourced schools lacked the technological infrastructure needed to support remote learning. This created significant barriers for students of color and those from economically disadvantaged backgrounds. A study examining learning loss during the COVID-19 pandemic found that losses were 55% greater among students whose parents had lower levels of educational attainment, further widening the achievement gap (Engzell et al., 2020). Similarly, across California, student grades dropped significantly during the pandemic, with more students receiving D’s and F’s (CalMatters). As a result, these students faced greater challenges in achieving educational outcomes comparable to their white and more affluent peers. Our research uses the Stanford Education Data Archive (SEDA) 2023 Version 5.0 dataset, which contains information on aggregated test scores (math and English language arts) of students with various racial and socioeconomic backgrounds across U.S. school districts between 2016 and 2023. This dataset is relevant because it allows us to analyze long-term trends in achievement gaps before, during, and after the pandemic, which helps us assess the pandemic’s impact. Given that the data highlights disparities, we believe schools must adopt targeted interventions and educational strategies to effectively address the needs of diverse student populations. If left unaddressed, these educational setbacks could have lasting effects on college readiness and socioeconomic mobility for affected students.
What are the implications of focusing primarily on standardized test scores to measure educational success, especially in a post-pandemic context?
What historical educational inequalities are mirrored in the pandemic’s impact on academic performance across different states, according to SEDA2023?
How might educators use the SEDA2023 dataset to tailor educational strategies that address the needs of diverse student populations effectively?

We decided to examine Ohio and California because the two contrasting states have different student demographic makeup and COVID policies, which allowed us to analyze the differences in their outcomes. California is one of the largest and most diverse states, with various socioeconomic and racial backgrounds, and implemented some of the longest school closures during the pandemic. On the other hand, Ohio differs in demographics and policy responses, and had different approaches to school reopening. By comparing these two states, we wanted to understand how differences in population, policy, and access to educational resources may have influenced student outcomes during and post pandemic.
