Which assessment keeps a record of school performance at the national level?

The assessment that keeps a record of school performance at the national level is the National Assessment of Educational Progress (NAEP). NAEP is often referred to as the "Nation's Report Card" and is the only assessment that provides a comprehensive view of what students across the United States know and can do in various subjects, including mathematics, reading, and science. It is administered periodically to a representative sample of students in different states and grades, allowing for comparisons over time and across demographic groups.

NAEP results are crucial for understanding educational trends and informing policy decisions, as they highlight areas where students are excelling and where improvements are needed on a broader scale. This national-level data is vital for educators, policymakers, and the public as it helps gauge the effectiveness of educational strategies and resource allocations across the country.
