History of the Rice Purity Test
The name connects the checklist to Rice University, but many precise origin stories circulate without citations. This timeline separates what Rice-affiliated sources establish from what remains uncertain.
Independent implementation
PurityTest.io is not operated by, endorsed by, or affiliated with Rice University. It publishes an independent browser-based version of the checklist and uses Rice-affiliated sources only to explain the documented history.
Source-led timeline
1990s
A Rice archival record exists
Rice University's Woodson Research Center catalogue includes an archival object titled “Purity Test, 1990s.” This establishes a Rice-associated record in that decade; the catalogue entry alone does not prove a single creation date, author, or unchanged canonical wording.

Rice-affiliated reporting documents evolution
The Rice Thresher published an account of the test's evolution and spread beyond Rice. That reporting supports a history of changing versions and wider circulation, rather than the idea that every modern website reproduces one fixed official edition.

A versioned independent checklist
This site's question set was reviewed on 2026-07-18. The review date describes this implementation only. It does not claim that the wording is official, original, or endorsed by Rice University.
What remains uncertain
- •A single person or date responsible for creating every later version.
- •Whether any modern 100-question list preserves every line of an earlier campus version.
- •Population totals for how many people have taken the test across different websites and offline copies.
These points are left uncertain rather than filled with unattributed dates or popularity figures.
