Technology Readiness Levels (TRL) are a 9-step scale — from a basic principle observed in the lab to a system proven in the real world. They are the spine of the build-first Technology Readiness Pipeline. Read the levels, then assess where you stand.
TRL rises as evidence accumulates — research becomes a prototype, a prototype becomes a qualified, operational system.
Tap the highest milestone you have genuinely completed — TRL is cumulative, so every level beneath it is included automatically.
Tap your highest completed milestone — lower levels tick automatically. Tap it again to step back down.
