Choose by how you will use the records
A school data download suits a defined analysis, reproducible joins, or an offline review. An API can suit an application that requests selected records during use. Delivery format does not establish accuracy, completeness, or freshness: both need documented field definitions, source years, and coverage.
When a download fits
Use a versioned file when you need to inspect every row, compare releases, or reproduce an analysis later. Save the release identifier, data dictionary, and any filters with the result. Check whether the delivery is CSV, a spreadsheet, or a PDF report; those formats support different kinds of analysis.
When to evaluate an API
For an interactive application, confirm endpoint availability, authentication, record identifiers, pagination, field coverage, rate limits, and version behavior before integration. Ask whether an update can change an existing response and how to retrieve the snapshot used in a previous result. An API response can contain historical data even when requested today.
A practical acceptance check
- List the fields and geographic coverage the project needs.
- Inspect a sample for identifiers, types, source years, and missing values.
- Verify duplicate and unmatched records using a small representative join.
- Confirm the actual delivery format, update terms, and permitted uses before ordering.
What to inspect at K12 Atlas
Start with the free Austin ISD sample, source and coverage methodology, and available packages. Check API access details before planning an integration. For federal raw files, inspect NCES Common Core of Data files and CRDC data and collection documentation directly.
