How to read school graduation rate data

The short version

The 4-year adjusted cohort graduation rate, or ACGR, is a high-school metric. It should not be expected on every school profile because many schools do not serve a graduating cohort. In K12 Atlas, graduation rows can come from state files or EDFacts fallback. That makes source year and estimated flag important. A rate with a small cohort can move more sharply than a rate with a large cohort.

How to use it

• Keep the source and vintage visible.
• Separate reported zeros from missing or skipped values.
• Use the field as context, not as a rating or recommendation.
• Link back to the source-backed data page when citing it.

Common mistakes

The most common mistake is stripping the field away from its source year. A school profile can contain CCD directory fields from 2023-24, CRDC fields from 2021-22, finance fields from FY 2022, and state accountability fields from a different state release. Those are all useful, but they should not be merged into one timeless claim.

The second mistake is converting a source field into a label. K12 Atlas does not publish composite scores or editorial ratings. The recommended pattern is to show the value, source, vintage, denominator, and limitation so the reader can decide what matters for their analysis.

How this supports organic research

This page exists to answer a narrow school-data query and then route the reader into the evidence web. A definition links to a data story. A data story links to a CSV slice. A CSV slice links back to source notes, sample fields, and product pages. That structure helps researchers, journalists, and data buyers land close to the proof instead of a generic sales page.

When to use the field

Use it for source-backed filtering, due diligence, reporting, product enrichment, and field discovery. Do not use it for steering language, demographic inference, or housing guidance. If a sentence would still make sense without the source and vintage, it is probably too vague for K12 Atlas copy.

Practical use cases

Journalists use graduation rates to report on school achievement trends. Policy analysts use them to study school performance benchmarks. Researchers use graduation outcomes to join with post-secondary enrollment.

Refresh and maintenance

Updates annually as state DOEs release cohort files. Cohort sizes, ACGR rates, and estimation flags must move in sync to maintain data integrity.
