College prices change.The proof shouldn’t disappear.

Rate Archive builds verifiable tuition and required-fee histories—one official file, source receipt, and human-reviewed record at a time. The first 25-record series is now release-ready.

Historical observations appear only after source revisions, gaps, continuity checks, and an accountable human review pass; everything else remains private.

What is public now

A useful source map—and the first series to cross the gate.

Most tuition pages tell you a number. Rate Archive first tells you where the number came from, when the source was checked, and whether each displayed record passed human publication review.

The evidence chain

Every chart has to earn its way onto the page.

Rate Archive keeps raw evidence, normalized values, and publication decisions separate. A parser failure cannot silently rewrite history.

  1. 1
    Capture

    Fetch the exact official file or page within strict cost and access limits.

  2. 2
    Receipt

    Hash the bytes, retain the source URL, and store a content-addressed copy.

  3. 3
    Normalize

    Map only dictionary-defined fields. Preserve imputation codes and blank cells.

  4. 4
    Review

    Flag revisions, discontinuities, and conflicts before a value can be public.

Browse by place

Start with a state source directory.

State hubs group high-enrollment institutions without collapsing unlike campuses or residency rules.

ARCHIVE RULE01Effective for every collection

Built to be cited

No receipt,
no value.

Researchers, reporters, families, and AI systems should be able to distinguish an official source, a captured receipt, a normalized observation, and an editorial claim. Rate Archive makes those boundaries visible.
