Software Studio

We forge software that measures, adapts, and responds.

TestForge builds adaptive assessment engines, learning platforms, and operational systems for teams in education, healthcare, and beyond — full-stack, psychometrically grounded, shipped end to end.

What we do

Four kinds of software, one obsession: measurement.

We don't take every project. We take the ones where the software has to understand and respond to the people using it.

Adaptive assessment & psychometrics

Computer Adaptive Testing engines grounded in Item Response Theory, Rasch modeling, and Bayesian ability estimation — assessments that adjust to each learner in real time.

Learning platforms & LMS

End-to-end e-learning systems: video delivery, course catalogs, certification and CEU tracking, subscriptions and checkout, and the dashboards that hold it together.

Operational & business systems

Bespoke internal software that consolidates scheduling, workflow tracking, roles, and automation into a single source of truth for the teams that run on it.

Full-stack engineering & AI

Next.js, Supabase, Stripe, and Vercel as our default stack — with applied machine learning, structured content generation, and data visualization where they earn their place.

The difference

Most teams build quizzes. We build the engine underneath.

Real adaptive assessment is a measurement problem before it's a UI problem. Our work is grounded in the psychometric models that high-stakes testing actually relies on — so a score means something, and the next question is the right one.

Adaptive assessment platform

PassDeed

In production

An adaptive real estate exam-preparation platform for Texas, Florida, and California, built around a real Computer Adaptive Testing engine rather than a static quiz bank. Its free diagnostic estimates readiness, maps performance to each state’s official exam blueprint, 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
State-first question banks mapped to the official Texas, Florida, and California exam blueprints
Source-verified legal content and misconception tracking that identifies repeated conceptual gaps
