Stanford Education Data Archive — comparison guide

Public data files and technical documentation for comparing educational achievement and group differences across geographic units.

Dataset / methodology guide · Stanford Educational Opportunity Project

Read with context.

The archive lists multiple releases, including Version 6.0. Record the exact release, achievement scale, years and aggregation used. The separate recovery/trends products should not be silently mixed with the main archive.

Limits to keep in view

Version-specific estimates and scales are not interchangeable. Read codebooks, uncertainty and coverage notes. This record contains no downloaded student-level data or new calculations.

Connect evidence to action

Choose a question, verify the relevant jurisdiction, and explain the action you are asking someone to take. A source-backed draft is a starting point—not a message sent on your behalf.

Your working notes

Keep the context with the claim.

Write the question first

What are you trying to understand? Identify the population and place before looking for a number that might support your position.

Capture the measure

Record the source title, table or indicator, units, reference period and any stated uncertainty. Preserve the original wording of technical definitions.

Distinguish observation from explanation

A difference between groups can prompt further inquiry. It does not, by itself, identify the cause or establish the effect of a particular policy.
