ACGR

Adjusted cohort graduation rate is the 4-year graduation-rate measure used for high-school cohorts.

Definition

ACGR belongs with source year, cohort count, and estimated flag. It should not be expected on every school type.

How K12 Atlas uses it

The term appears in source-backed school data pages with the source, vintage, and limitation attached. The goal is to make the field citable without turning it into a score.

Source caveats

Definitions in school data are not just vocabulary. They control how a field should be queried, displayed, and cited. A term can come from NCES, CRDC, EDFacts, Census F-33, or a state agency, and each source has its own release cycle and missing-value rules.

Implementation rule

When this term appears in a K12 Atlas page, keep the definition near the field value. The useful pattern is source, vintage, denominator, and limitation. That keeps the page citable and prevents the term from becoming vague product language.

Organic role

This glossary page targets definitional searches and routes readers into deeper evidence pages. It should link to the data story that uses the term, at least one explainer, and the sample report. The goal is a compact authority web, not isolated dictionary entries.

What not to infer

A glossary definition should not be stretched into an outcome claim. It explains what a field means, where it comes from, and how it should be handled. It does not turn a source field into a score, recommendation, or housing claim. That boundary is part of the K12 Atlas editorial system.

Related buyer path

When a buyer needs this field across a district, metro, state, or the national file, the glossary should send them to the sample report first. The sample shows how the field appears with source notes, not just as isolated copy.
