• By Rob Carthy, Director of International Development, Northumbria University.

Attending Duolingo’s inaugural DETcon London, I anticipated a day focused on the evolving landscape of language testing. What I experienced was a candid, and at times controversial, conversation about the geopolitical, political, and technological pressures facing UK higher education. Duolingo may have been the convenor, but the themes of the day went to the heart of the sector’s future.

Here are ten of my key takeaways from a thought-provoking day.

1. Crisis is the New Business-as-Usual

“Since I started, we’ve faced crisis after crisis.” These words from Katja Lamping, Director of Student Recruitment at UCL, resonated deeply. From the pandemic to the fall of Kabul, Ukraine, and Gaza, the past five years have demanded a level of institutional reactivity we’ve never seen before. The clear message was that this isn’t a blip. As former Home and Foreign Secretary Jack Straw bluntly put it, the first rule of preparing for uncertainty is to “expect that the unexpected is going to happen.” For university leaders, strategic planning now looks less like a road map and more like training for a cross-country race in the dark.

2. Agility is Now a Core Competency

The flip side of constant crisis is the need for agile solutions. We heard how the Duolingo English Test (DET) became a vital tool during the pandemic because it was accessible when physical test centres were not. This story is symbolic of a wider truth: our traditional processes and partnerships can be brittle. To keep our doors open to global talent, we must build resilience and responsiveness into our operations, from admissions to student support.

3. The Political Headwinds are Strengthening

Jack Straw’s portrayal of the government’s immigration white paper was sobering. He spoke of a view that some university business models are “not sustainable.” And highlighted the view in Westminster that the student visa route was being used as a “racket” for asylum claims. I might have disagreed with him – many in the room did – but this is a view held by many and is a reality we must face.

Straw, and later in the day Rory Stewart, said the mood in Westminster is hardening regardless of who is in power. This government wants to bring down immigration. It’s often said Brits don’t mean students, but the stark reality is the government wants to get numbers down, and students are one, if not the easiest, lever they can pull. We must be on the front foot, demonstrating our commitment to robust compliance and ethical recruitment, and articulating the immense value international students bring—a value HEPI’s own research has quantified at a net £37.4 billion for the 2021/22 cohort alone.

4. Technology Can Deliver Both Access and Integrity 

A powerful message came from Duolingo’s CEO and co-founder, Luis Von Ahn, who shared his personal story of growing up in Guatemala and seeing how English proficiency could transform a person’s life, yet how prohibitive the cost of testing was. His core argument was that technology should be a democratising force. But most compellingly, he tackled the security question head-on. He argued that far from being less secure, an AI-powered test can offer greater integrity than a traditional test centre. The ability to use AI to monitor hundreds of behaviours simultaneously—from eye-gaze to keystroke patterns—in addition to human proctors, presented a powerful case that a digital-first approach doesn’t have to mean a compromise on security; it could, in fact, mean the opposite.

5. The Biggest Risk of AI Might Be Inaction

In a fascinating session on technology, Dr. Laura Gilbert OBE of the Tony Blair Institute offered a powerful counter-narrative to the usual fears around AI. She argued that the biggest risk might be “not doing it at all.” While we worry about academic integrity, we risk missing the opportunity to use AI to solve our biggest challenges, from relieving the administrative burden in admissions to revolutionising personalised learning. Her point that technology like AI is essential to sustaining public services like the NHS has direct parallels with the financial challenges in our own sector.

6. Trust in Technology Must Be Earned

Dr. Gilbert was clear: you cannot just demand trust in AI. It must be earned through what she called “radical transparency.” For universities adopting tools like the DET for high-stakes admissions, this is a critical lesson. We must demand evidence from our tech partners that their tools are secure, equitable, and have been rigorously evaluated for bias. Publishing that evidence, as Duolingo was highlighted as a good example, should become the industry standard.

A crucial warning from Dr. Gilbert was that if left to market forces, AI will inevitably make the advantage more advantaged, worsening societal inequality. For a sector committed to widening participation, this is a profound challenge. As we adopt AI, we must actively and consciously steer it towards closing, not widening, access gaps. The goal of using technology to reach students from previously untapped regions is a noble one, but it requires a constant and active focus on equity.

7. AI Isn’t Just A Buzzword

It’s a transformative force in assessment, personalisation and inclusion. I was struck by Duolingo’s mission-led approach, especially its ability to deliver high-quality, low-cost English testing to learners across the globe, including refugee and displaced students. Innovations like adaptive testing, AI-driven speaking practice, and real-time fraud detection redefine what “secure” and “authentic” assessment looks like. The session challenged my assumptions about test integrity and proved that democratisation doesn’t mean compromise. The balance between rigour and compassion resonated strongly—proof that access and excellence can coexist. At Northumbria, we’re increasingly mindful of our role in enabling fairer pathways into UK higher education. The Duolingo English Test is no longer a disruptor—it’s fast becoming a vital enabler that we should all be paying attention to.

8. Is it a Brave New World?

Rory Stewart’s session offered a powerful analysis of our turbulent times, contrasting the post-1989 era of liberal democracy and globalisation with our current “shadow world” of populism, protectionism, and a retreat from a rules-based international order. Stewart highlighted key shifts, including China’s rise without democratisation, the 2008 financial crisis, and the chaotic impact of social media and failed interventions in Iraq and Afghanistan. Stewart warned that global trends, like Trump’s attacks on US universities, could easily manifest in the UK, emphasizing that “what happens in the US can come here”. These attacks include significant funding cuts and threats to academic freedom over perceived ideological biases. This serves as a stark reminder for UK higher education to remain vigilant against similar political pressures.

9. A Little Can Go A Long Way

The session on the carbon cost of testing made me sit up. John Crick from the International Education Sustainability Group (IESG)  revealed that switching from test centre-based exams to online alternatives can cut carbon emissions by up to 98%. The equivalent of planting a Sherwood Forest of trees every year. The analysis showed that the biggest environmental impact comes from travel to test centres, especially in regions without local provision. What struck me was how easily we overlook this area in our sustainability strategies. IESG’s meticulous modelling gives us a much-needed baseline to challenge assumptions and examine the unintended carbon consequences of our English language policies. It’s a conversation starter—but one we in international education need to have now if we’re serious about meeting climate goals.

10. Our Soft Power is Precious, But Not Guaranteed

The conference ended with a discussion on the UK’s soft power and the launch of Duolingo’s Welcome Project, which seeks to provide a place for students displaced by the turmoil in the US with opportunities in the UK.

While our leading universities remain beacons of global influence, the day’s discussions made it clear this cannot be taken for granted. A domestic political narrative focused on clamping down on immigration, combined with financial models that are visibly creaking, risks tarnishing one of the UK’s greatest exports. We must collectively find a way to reconcile the need for control and sustainability with the projection of being an open, welcoming, and world-leading destination for education.
