Stanford education data archive (SEDA)

Comparing academic performance across states has historically been difficult because each state administers its own assessments and establishes its own performance standards.

The Stanford Education Data Archive, commonly known as SEDA, brings state assessment data together on a nationally comparable scale. Developed by Stanford University’s Educational Opportunity Project, SEDA allows educators, policymakers, and community leaders to explore patterns in educational opportunity across schools, districts, communities, and states.

SEDA does not explain why a particular pattern exists. Instead, it provides a valuable starting point for asking better questions and identifying schools or communities that may warrant deeper study. SEDA provides information related to:

• Achievement: How average academic performance compares with national patterns

• Learning Rates: How much students learn as they progress through grade levels

• Trends: How achievement and learning rates are changing over time

• Educational Opportunity: How academic outcomes relate to community and socioeconomic conditions

"The Stanford Education Data Archive (SEDA) is an initiative aimed at harnessing data to help scholars, policymakers, educators, and parents learn how to improve educational opportunity for all children."
