Technology Readiness Levels

Technology Readiness Levels (TRLs) are a method for estimating the maturity of technologies. The use of TRLs enables consistent, uniform discussions of technical maturity across different types of technology. A technology's readiness level is determined during a Technology Readiness Assessment that examines program concepts, technology requirements, and demonstrated technology capabilities.

TRLs are based on a scale from 1 to 9 with 9 being the most mature technology, please find the definition of each level in the following list:

  • TRL 1 - Basic research: basic principles are observed and reported
  • TRL 2 – Applied research: technology concept and/or application formulated
  • TRL 3 – Critical function, proof of concept established
  • TRL 4 – Laboratory testing of prototype component or process
  • TRL 5 – Laboratory testing of integrated system
  • TRL 6 – Prototype system verified
  • TRL 7 – Integrated pilot system demonstrated
  • TRL 8 – System incorporated in commercial design
  • TRL 9 – System ready for full scale deployment
