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

RNTestPro

In production

An NCLEX exam-preparation platform for nursing students built around a real Computer Adaptive Testing engine — not a static quiz tool. Question selection is driven by live ability estimates, with Next Generation NCLEX case studies modeled on the Clinical Judgment Measurement Model.
