Why Most Technology Readiness Level Assessments Lie to Everyone Involved

Technology Readiness Levels were invented by NASA in the 1970s to give engineers a shared vocabulary for how mature a technology actually was. Nine levels, TRL 1 through TRL 9, from basic principles observed all the way to proven flight heritage. Clean. Logical. Useful, at least in aerospace, where the environments are well-defined and the tests are objective.

Somewhere along the way, the rest of the innovation ecosystem adopted TRL scoring without adopting the discipline behind it. Now the number on a tech transfer summary sheet means almost nothing.

The Problem Isn't the Scale. It's Who's Scoring It.

Ask an academic inventor what TRL their technology sits at. Then ask a seasoned licensing associate at the same institution. Then ask an industry partner who's tried to integrate something similar before. You'll get three different answers, often separated by two or three levels.

That gap isn't dishonesty, exactly. It's motivated reasoning combined with vague definitions. A researcher who has demonstrated a proof-of-concept in a controlled lab setting with optimized reagents, ideal temperatures, and a graduate student running it will confidently say TRL 4 or even TRL 5. A manufacturing engineer looking at the same data will say TRL 2 or 3, because they're mentally simulating what it would take to make the thing work in the real world, repeatedly, without the grad student.

Both people are technically using the same scale. Neither is lying. But the gap between their assessments can mean millions of dollars in misallocated resources and deals that collapse eighteen months in.

What TRL Was Never Designed to Capture

Even when scored accurately, TRL only measures one axis: technical maturity. It says nothing about manufacturing readiness, which has its own separate scale (MRL) that almost nobody outside defense contracting uses. It says nothing about regulatory pathway. It says nothing about whether a market actually exists.

A TRL 6 material science innovation, validated in a relevant environment, might be twelve years and $80 million from commercialization if the relevant environment is inside a human body. A TRL 4 software tool might reach market in eighteen months because deployment is cheap and iteration is fast.

Using TRL as a proxy for commercial readiness is like using a building's floor count to estimate its rent. Correlated in some contexts. Wildly misleading in others.

How Deals Get Distorted

Here's where this becomes an actual commercial problem. When a university files a patent and a licensing associate writes up the technology summary, the TRL score often gets anchored to the inventor's self-assessment. That number then travels, into marketing materials, into pitch decks, into term sheet conversations with potential licensees.

A corporate partner's business development team sees TRL 5 and starts modeling a three-year path to product launch. Their internal champion uses that assumption to get budget. Two years later, when they discover the technology has never been validated outside the inventor's specific lab setup with bespoke equipment, the deal doesn't just stall, it poisons the relationship. The company pulls back from future university deals. The technology sits unlicensed.

This isn't hypothetical. It's a pattern that plays out constantly, in sectors from medical devices to agtech to advanced materials.

A More Honest Approach

The fix isn't complicated, but it requires institutional honesty that's uncomfortable. Three things actually work:

Independent validation before the number is published. Some tech transfer offices now require that TRL scores above 4 be reviewed by an external technical assessor with industry experience in that specific domain. Not a consultant who writes reports, someone who has built and shipped something in that space. The number gets harder to inflate when the person scoring it has seen what TRL 7 actually looks like in practice.

Publish the scoring rationale, not just the number. A TRL score without the evidence log is just an opinion. What tests were run? Under what conditions? With what equipment? This documentation slows things down slightly at the front end and saves enormous amounts of time and credibility on the back end.

Pair TRL with a plain-language gap analysis. What would it take to move from the current level to TRL 7? What's the estimated cost? What's the single biggest unknown? Answering these questions honestly, in writing, in the technology summary, resets expectations before they calcify into bad assumptions.

None of this makes TRL a perfect instrument. But it moves the conversation from a number that feels objective to an honest accounting of where the science ends and the hard work begins. That's what industry partners actually need. And frankly, it's what the technology deserves.
