Too many entrants in the credentialing and assessments space make the same mistake. They build for the test-taker: smoother UX, faster scoring, cheaper fees. And then they wonder why growth stalls.

The credentials or tests that dominate don’t win because of who takes them.

They win because of who accepts them.

The order matters.

Acceptance drives adoption, not the other way around.

Every market in credentials and assessments runs on this same asymmetry:

In other words, these markets aren’t driven by consumer demand; they are controlled by gatekeepers. And that’s where most entrants lose the plot: they chase convenience features for users instead of legitimacy signals for institutions.

The core truth: In credential markets, legitimacy is the real currency. And legitimacy lives with those who hold the power to say “we accept this.”

Over the past two decades advising assessment providers, universities, and workforce bodies, I’ve seen this mistake repeat itself. Product teams jump straight to the user experience while the institutions they depend on are still debating policy, data standards, and fairness frameworks. The result is predictable: strong technology, weak adoption.

For decades, TOEFL was the default assessment that every international applicant to the U.S. took, because every major U.S. university required it. It was the gold standard because it was the only standard.

Then IELTS broke the monopoly, by getting U.S. institutions to accept it. IELTS went directly to admissions offices. The pitch to institutions wasn’t about UX or design; it was about reliability, scoring validity, and comparability. The pitch to students wasn’t “this is easier” or “more convenient” it was “this is trusted by institutions.”

It started by understanding what admissions officers actually valued: predictable scoring, transparent data pipelines, and an assurance that the test wouldn’t expose them to fraud or fairness complaints. In institutional markets, the perceived risk of acceptance often outweighs the potential benefit of innovation. That’s the calculus many entrants overlook.

IELTS’s objective was to break TOEFL’s monopoly in the U.S. (IELTS was already the default assessment in the U.K. and Commonwealth countries). Once a few top schools announced they would accept it, everyone else followed. The signal was: if elite universities say IELTS is legitimate, other schools could safely follow suit.

By the time TOEFL executives noticed, the test-taker market had already moved. Widely accepted in the U.K. and now in the U.S. as well, IELTS rapidly gained market share amongst prospective students who wanted to keep their country of destination options open.

IELTS cracked TOEFL’s monopoly, and the Duolingo English Test (DET) blew the door off its hinges.

When it launched, DET looked like a toy: an app-based test from a language-learning company best known for its cartoon owl. Executives within IELTS and TOEFL dismissed it as unserious; unworthy of being a competitor. But Duolingo followed the same playbook IELTS had proven: start with institutional acceptance.

Before the pandemic, DET had a few hundred universities on its list. Then COVID-19 shut down testing centers worldwide, and Duolingo moved fast. Within months, it secured approvals from elite universities—Yale, Columbia, Duke, MIT. Once those names appeared on the list, thousands of others followed. DET didn’t sell convenience to students; it sold continuity to institutions.

That cascade didn’t happen by chance and indeed it’s a textbook strategy many of our clients pursue: get a handful of prestige institutions to make the first move. Duolingo managed to execute the strategy faster than its competitors expected.

While TOEFL and IELTS scrambled to launch at-home versions, Duolingo was already digital, verified, and ready to scale. It offered what admissions officers needed most in that moment: a defensible, remote-administered test.

By 2025, more than 6,000 programs accepted DET—up from fewer than 100 in 2016. The test’s lower cost, accessibility, and turnaround time were differentiators, but they only mattered after acceptance was secured. No student would pay even $59 for a test that no university would recognize. Legitimacy came first; affordability simply accelerated adoption.

This tale of two acts is a story about legitimacy in gatekeeper-driven markets. The winner isn’t the test that’s better to take. It’s the one that’s safe to accept.

When institutions updated their policies, student preference realigned instantly. That’s why IELTS’ expansion was so efficient: every new university on the list was a multiplier, not a single new customer. And Duolingo didn’t just digitize English language testing. It redefined the boundary between consumer tech and institutional trust. And once again, legitimacy—not innovation—was the real engine of growth.

The lesson: In credential and assessment markets, adoption is an outcome, not a strategy. You don’t win the learner until you’ve won a place on the list.

It turned out the English testing market wasn’t a consumer business after all. It only looked like one, because of who pays the test fees.

The same asymmetry that defines student testing plays out across the professional world. Credentials rise or fall not on learner enthusiasm, but on employer recognition.

For years, HRCI’s PHR and SPHR were the default in HR. Then SHRM entered in 2015 and flipped the market—not only through marketing to HR professionals, but by lobbying employers. When Fortune 500 firms updated job descriptions to “SHRM-CP or SHRM-SCP preferred,” the talent pool followed. Legitimacy shifted at the top, and professionals adjusted instantly.

Salesforce’s Trailhead program wasn’t built for individual learners; it was designed for partners and employers who needed certified talent. Google took the same approach with its Career Certificates, securing pledge partnerships with 150+ employers before marketing to learners. “Accepted by employers” was the strategy.

Cloud and IT certifications succeeded for the same reason IELTS did: they became the safe default for hiring managers. Once job postings specified those credentials, the learner market scaled itself.

None of these are consumer acquisition stories. They are stories of institutional alignment where credibility precedes adoption and employers act as the regulators of legitimacy. Once gatekeepers endorse the credential, everyone downstream falls in line.

In every one of these cases, the breakthrough wasn’t a better credential, it was a better understanding of employers’ incentives. Employers don’t just want proof of skill; they want liability protection, comparability, and signals that simplify screening.

Every credential or test runs on two engines at once: one faces individuals, the other faces institutions. One side sells to learners; the other sells to gatekeepers. The balance between the two determines whether a product scales or stalls.

The critical sequence is fixed. Legitimacy must come before volume can come. Once institutions say yes, consumers follow. A test-taker never asks, “Which one do I like?” They ask, “Which one gets me accepted?” That single question reveals who the real customer is.

The right sequence is diagnostic. Emerging Strategy’s research often begins on the institutional side: understanding how decision-makers define trust, what data or validation frameworks they require, and how competing options are perceived internally. Only after that landscape is mapped does it make sense to study consumer willingness to pay or brand preference. Otherwise, you’re optimizing demand that can’t convert.

Most entrants confuse the two markets. They chase users before they’ve earned institutional trust, mistaking temporary interest for durable adoption. Until gatekeepers accept the product, no amount of UX polish or price advantage creates a real market.

There are only two ways legitimacy takes hold:

This is the dominant model. Universities, regulators, or employers decide what counts. Demand isn’t built through advertising—it’s earned through recognition.

This model rewards credibility over creativity. You can’t growth-hack your way past a gatekeeper.

In less regulated or fragmented markets, legitimacy can bubble up from results. When outcomes are visible—placements, portfolio success, earnings—trust builds from demonstrated proof, not institutional blessing.

These models thrive only where gatekeepers are weak. When authority is centralized, legitimacy once again flows downward.

The diagnostic is simple:Who decides “this counts”? Can outcomes prove legitimacy on their own? If not, start B2B.

In every credential or assessment business, growth depends on mastering this sequence: earn legitimacy first, then scale demand.

Across education, workforce, and professional certification markets, the products that win are the ones institutions trust. Adoption follows legitimacy, every time.

Growth comes from sequencing strategy correctly: diagnose the institutional calculus first, then design for the user. UX, pricing, and marketing amplify momentum only after the gatekeepers say ‘yes.’

The real advantage lies in earning acceptance early. Once legitimacy is secured, volume, loyalty, and pricing power flow naturally downstream.

The lesson for new entrants is counterintuitive but simple: your primary customer isn’t the one paying the fee. Build for the institution or employer that determines whether a credential or assessment means anything to them.

The pattern is a familiar one across sectors: once you know who the real customer is, growth stops being a mystery and becomes a sequence.
