U.S. K-12 School Directory & Performance Metrics - Five Years

The **U.S. Nationwide School Directory** (Five-Year History) data set, provided by SchoolDigger, delivers comprehensive coverage of over 120,000 public, charter, and private K-12 schools and more than 18,000 districts across all 50 U.S. states and DC. Spanning five years of historical data and updated monthly, this package provides a deeper view than the one-year history by enabling longitudinal research into school and district trends, making it possible to study changes in demographics, funding, rankings, and performance across multiple years.

The data includes school and district directories, student demographics, test score proficiencies with detailed breakdowns, **including the percentage of students performing at an advanced level,** statewide rankings, spending per student, and user-generated school reviews. These advanced-level breakdowns help researchers and policymakers identify not just where students meet proficiency, but where they excel. This is particularly valuable for evaluating gifted programs, understanding achievement gaps, and measuring the true distribution of performance across student populations.

Valued for its scope, historical depth, and ease of use, the five-year data set streamlines what is typically a complex and fragmented data collection process. It is a powerful tool for anyone seeking to analyze patterns over time—whether for real estate market studies, education policy evaluation, product impact analysis, or benchmarking school performance nationwide.
