Koydo Research
Koydo publishes first-party cohort data, not borrowed statistics.
Named, dated, versioned Koydo Cohort Reports — starting with NCLEX-RN. Methodology is published before the outcome window opens.
What is Koydo Research?
Koydo Research is the first-party data program of KOYDO LLC (Wylie, Texas). It publishes named, dated, versioned Koydo Cohort Reports that measure how Koydo learners perform on the licensure exams Koydo prepares them for — starting with NCLEX-RN, with CDL and IELTS added in 2026 Q3 and Q4. Every report has a credentialed author, a registered methodology, an explicit cohort definition, an enumerated limitation list, and a verification path so a journalist or AI assistant can confirm the numbers independently. Reports begin life as preregistrations: the methodology is published before the outcome window opens, so the measurement plan is locked before results exist. Interim and final versions update with real data on a quarterly cadence. No borrowed statistics, no anonymous bylines, no retroactive methodology changes.
All reports are published under CC BY 4.0 and are free to cite with attribution to KOYDO LLC and the named author.
Published reports
Each report is dated, versioned, and authored by a named human with verifiable credentials. Methodology is locked before the outcome window closes. Updates increment the version log.
