Platforms we've designed, built, and shipped.

A spread across assessment, education, operations, and data — each one taken end to end. Some are public products; one is client-confidential and described by capability only.

Adaptive assessment platform

PassDeed

In production

A readiness-diagnostic platform for the Texas Real Estate Sales Agent exam, built around the same computer-adaptive testing discipline as our other assessment engines rather than a static quiz bank. A free adaptive diagnostic estimates exam readiness and shows candidates exactly what to fix before test day.

CAT engine using Item Response Theory, producing a 0–100 readiness score with a stated confidence range
Coverage mapped to all 14 TREC exam domains — 8 National, 6 Texas State Law — weighted by question difficulty
Misconception tracking that flags repeated conceptual gaps rather than just counting wrong answers
