Noam Angrist and colleagues set out a research agenda designed to make implementation itself an object of rigorous study. Their central claim is deceptively simple: the frontier of education research and practice is no longer just discovering what works, but understanding how to make it work repeatedly, equitably and at increasing scale. The authors write that there is growing evidence on what works, and that the task now is to translate that evidence into action and to study that translation systematically, so that effective programs can be delivered again and again to achieve what they describe as effective, equitable and enduring learning for all. In their framing, implementation is not an afterthought to research but a scientific discipline in its own right.

The scale of the problem gives the argument its urgency. Although most children around the globe now enroll in school, a large share of them complete years of schooling without mastering basic literacy and numeracy. Decades of randomized trials and rigorous evaluations have produced genuine breakthroughs: teaching at the right level, structured lesson plans, and cost-effective tutoring programs have all shown strong effects in carefully managed studies. Yet when governments adopt these interventions and roll them out across thousands of schools, effects often shrink dramatically or disappear altogether. The authors point to a diagnostic blind spot that makes this pattern hard to interpret: education research rarely measures how faithfully a program is implemented or how widely it is adopted, so it is often impossible to tell whether disappointing results reflect a flawed program or a flawed rollout.

This distinction between program failure and implementation failure is the conceptual heart of the new agenda. A curriculum reform that succeeds when delivered by a motivated NGO with intensive training and supervision may falter when a ministry of education must train tens of thousands of teachers, manage supply chains, monitor compliance and sustain funding across political cycles. Without data on fidelity, dose, reach and adaptation, evaluators cannot distinguish between a program that genuinely does not scale and a program that was scaled badly. The authors argue that this measurement gap has distorted the field’s accumulated evidence base, leading policymakers to abandon promising interventions prematurely or, conversely, to scale up programs whose real-world performance was never properly understood.

To address this, Angrist and colleagues call for stronger implementation science in global education, drawing explicitly on lessons from health care. Over the past two decades, implementation science has become an established field in global health, where researchers study the barriers and facilitators to delivering interventions such as vaccination campaigns, HIV treatment and maternal health programs. Health researchers have developed validated frameworks for measuring fidelity, adoption, penetration and sustainability, and they routinely build implementation questions into trial design from the outset. Education, the authors contend, has the scientific foundations to do the same: a mature experimental toolkit, growing administrative data systems and an expanding corps of researchers embedded within government systems. What has been missing is a shared framework that treats the journey from evidence to practice as a staged, studyable process.

That framework is the paper’s most concrete contribution. The authors propose a four-stage pathway for turning educational research into effective, equitable practice at scale: efficacy trials, effectiveness trials, policy plans and large-scale implementation. In the first stage, interventions are tested under tightly controlled conditions to establish whether they can work at all. In the second, they are evaluated in real-world settings across diverse populations, schools and implementers to establish whether they do work outside ideal circumstances. The third stage involves translating trial evidence into concrete policy plans that account for cost, political feasibility and delivery systems. The fourth stage is full-scale implementation, where the intervention meets the realities of national education systems, and where, crucially, researchers continue to measure, learn and adapt.

Each stage asks different questions, and the authors emphasize that the later stages have been chronically understudied. Efficacy and effectiveness trials are now relatively common in education research, but the transition from trial to policy and from policy to system-wide delivery remains poorly documented and poorly theorized. The framework insists that scalability is not a binary property of a program but an empirical question that must be tested: does the intervention work across diverse populations and real-world settings, and is it affordable and sustainable when delivered through ordinary government channels? Cost-effectiveness, the authors argue, deserves a central place in this calculus, because an intervention that produces modest learning gains at very low cost may deliver more total benefit at scale than a more powerful but prohibitively expensive alternative.

The equity dimension of the framework is equally deliberate. Programs that succeed on average can mask deep disparities, benefiting children in well-resourced urban schools while leaving behind those in remote, underfunded or crisis-affected settings. By embedding equity into every stage, from trial sampling to implementation monitoring, the agenda aims to ensure that scale-up narrows rather than widens learning gaps. The authors also highlight durability: education systems are subject to political turnover, budget shocks and shifting donor priorities, and interventions that depend on continuous external support rarely survive. Implementation science, in their view, should identify the design features and system conditions that allow gains to endure after the researchers and funders move on.

The authors are candid about the cultural shift their agenda requires. Education economists, psychologists and evaluators have built impressive evidence on what works, but the incentives of academic research reward novel findings from clean trials rather than the slower, messier work of studying delivery. Governments, meanwhile, often lack the time, data and technical capacity to diagnose implementation failures before scaling decisions are made. Bridging this divide means embedding researchers within ministries, building measurement of implementation into routine administrative data, and designing evaluations that answer the questions implementers actually face. The payoff, the authors argue, is a virtuous cycle in which more science makes it into implementation and more implementation is made scientific.

Ultimately, the agenda is a bet that the next large gains in global learning will come not from new interventions but from better delivery of known ones. If the field can systematically study how programs are adopted, adapted, funded and sustained, the growing library of proven interventions could finally translate into learning gains for the hundreds of millions of children who currently sit in classrooms without acquiring basic skills. As the authors put it, implementation science can support the ultimate goal of all children learning. The framework they propose offers the field a roadmap for getting there, one carefully studied stage at a time.

The core problem is deceptively simple. Fortification works by adding essential micronutrients, such as iron, zinc, vitamin A, folic acid, iodine and B vitamins, to staple foods and condiments that populations already consume regularly. Salt iodisation, the fortification of wheat and maize flour, and the enrichment of edible oils and sugar have collectively prevented countless cases of goitre, neural tube defects, anaemia and blindness. The World Health Organization and the Food and Agriculture Organization codified the technical principles of this approach in their landmark 2006 guidelines on food fortification with micronutrients, which emphasize that a food vehicle must be consumed in sufficient and relatively consistent quantities by the target population before it can serve as an effective delivery channel for added nutrients.

That consumption requirement is precisely where many programmes stumble, particularly in low- and middle-income countries where the burden of micronutrient deficiency is concentrated. National fortification programmes tend to focus on a narrow set of vehicles, most commonly wheat flour, maize flour, salt, oil and sugar, because these are centrally processed foods that manufacturers can fortify at scale under regulatory oversight. The Global Fortification Data Exchange documents that the majority of countries with fortification standards have legislated programmes built around these few staples. But dietary patterns are not uniform within or between countries. Rural households may mill their own grain outside industrial channels, urban consumers may shift toward imported or processed foods, and the poorest families may consume very little of the fortified staples at all, relying instead on other foods that never pass through a fortification facility.

The new research highlighted in the commentary takes a systemic approach to this mismatch. Using publicly available household consumption and expenditure data from ten West African countries, the study maps which foods are eaten in sufficient quantities by which population groups, and cross-references those patterns with estimates of micronutrient intake and deficiency risk. The findings are striking: to reach the populations most at risk of micronutrient deficiencies, a wider mix of fortified foods than is currently considered for fortification would be needed. In other words, the standard portfolio of flour, oil, salt and sugar is insufficient to deliver adequate micronutrients equitably across diverse West African populations, because different wealth strata, regions and demographic groups obtain their calories and nutrients from substantially different baskets of foods.

This equity lens represents a significant shift in how fortification success is measured. Traditional programme evaluations often report national-level coverage, the percentage of households consuming any fortified food, or the technical quality of fortification at the factory level. Those metrics can look impressive on paper while masking deep disparities in who actually benefits. A programme may achieve high nominal coverage of fortified wheat flour while the poorest quintile, rural children and women of reproductive age, the groups most vulnerable to anaemia and other deficiency conditions, consume negligible amounts of the fortified product. When coverage is assessed against need rather than against consumption of any fortified food, the gaps become stark, and the case for expanding and diversifying the range of fortified vehicles becomes compelling.

The implications for programme design are far-reaching. First, the analysis underscores the value of leveraging the growing volume of publicly available dietary survey data to inform fortification policy. Household consumption and expenditure surveys, national demographic and health surveys, and dedicated dietary intake assessments collectively contain the raw material needed to identify which foods each population subgroup consumes in fortification-relevant quantities. Governments and their partners can use such data to move beyond one-size-fits-all vehicle selection and toward portfolios tailored to national and subnational dietary realities. This data-driven framework offers a replicable template that other regions with high burdens of hidden hunger could adapt, provided comparable survey data are available and kept current.

Second, the findings suggest that programme planners should consider fortifying a broader array of foods, including foods consumed by lower-income and rural households that traditional programmes have overlooked. Candidate vehicles might include additional cereals, legume flours, condiments such as bouillon cubes, and other centrally processed or semi-processed products that feature prominently in local diets. Expanding the vehicle mix is not without challenges: each new fortified food requires feasibility assessment, industrial capacity, regulatory standards, quality assurance systems, monitoring and consumer acceptance. But the cost of leaving the most vulnerable populations unserved is measured in preventable childhood mortality, impaired cognitive development, reduced adult productivity and intergenerational cycles of malnutrition, costs that dwarfs the marginal expense of extending fortification to additional foods.

The broader context reinforces the urgency. Recent global assessments of micronutrient intake, including work by Osendarp and colleagues published in the Food and Nutrition Bulletin, have documented the scale of inadequate vitamin and mineral consumption across low- and middle-income countries, while companion analyses by Friesen and colleagues in The Lancet Global Health have examined the reach and quality of existing large-scale fortification programmes. Together with the new West African modeling work led by Tang and colleagues in Nature Food, these studies sketch a consistent picture: fortification is effective where it is well matched to consumption, but coverage remains incomplete and inequitable when programme design relies on a narrow set of vehicles selected without adequate attention to who eats what.

For policymakers, the message is both a warning and an opportunity. The warning is that continued investment in fortification programmes designed around convenience rather than equity risks entrenching nutritional disparities even as headline coverage statistics improve. The opportunity is that the analytical tools needed to close these gaps already exist, in the form of public dietary datasets and systematic frameworks that link consumption patterns to micronutrient needs. Adams concludes that building more equitable fortification programmes will require deliberate effort to match the foods that deficient populations actually consume with the vehicles selected for nutrient delivery. As hidden hunger continues to undermine health and development across West Africa and beyond, that matching of needs and consumption may prove to be the decisive factor determining whether the next generation of fortification programmes fulfills their considerable public health promise.

The curriculum’s design responds to a growing awareness within the healthcare community that implicit biases and systemic inequities can adversely affect patient care and outcomes. By incorporating DEI principles directly into psychiatry training, the researchers aim to prepare future doctors to better understand the cultural and social factors that contribute to mental health issues, ensuring that all patients receive respectful and informed care regardless of their personal circumstances.

Central to the development of this curriculum is a commitment to experiential learning. The researchers emphasize that traditional lecture formats alone are insufficient to instill a deep understanding of DEI principles in medical students. Instead, their curriculum incorporates interactive workshops, role-playing scenarios, and case studies that encourage students to engage with complex social issues actively. This approach enables future psychiatrists to cultivate empathy and improve their ability to navigate challenging interpersonal dynamics, ultimately leading to more compassionate medical practices.

In addition to enhancing the students’ knowledge and skills, this curriculum aims to dismantle the barriers that may discourage underrepresented groups from pursuing careers in psychiatry. The research team highlights that by embedding DEI into medical education, they hope to inspire a new generation of healthcare professionals who reflect the diversity of the populations they serve. This alignment of workforce representation and patient demographics is not just a matter of equity but is essential for improving the overall quality of mental health care.

Another vital aspect of the curriculum is the emphasis on self-reflection and personal accountability. Students are encouraged to explore their own biases and examine how their identities influence their interactions with patients. This introspective component is crucial, as it fosters a deeper awareness of the social determinants of health and the systemic barriers that many patients face. By integrating self-reflection into psychiatric education, the curriculum challenges students to confront uncomfortable truths and recognize their role in shaping a more equitable healthcare landscape.

Moreover, the researchers have developed assessment tools to evaluate the effectiveness of the curriculum in real-time. These assessments enable educators to gauge students’ understanding of DEI principles and their application in clinical settings. By continuously monitoring progress, the researchers hope to refine the curriculum further, ensuring it meets the evolving needs of both medical students and the communities they serve.

The significance of this work extends beyond medical education; it represents a broader shift towards recognizing and addressing health disparities on a systemic level. By educating future psychiatrists about the importance of DEI, the curriculum aligns with national health objectives aimed at reducing inequalities in healthcare access and treatment. This alignment reinforces the idea that mental health care is best delivered when it is approached through a lens of equity and understanding.

In the context of ongoing discussions around healthcare reform, this initiative provides a tangible example of how educational practices can lead to meaningful change. The emphasis on DEI in psychiatry training signals a commitment to creating a healthcare environment where every individual—regardless of race, gender, sexual orientation, or socioeconomic status—feels valued and respected. Such an environment is critical for promoting trust and collaboration between patients and healthcare providers.

In addition to its innovative pedagogical approaches, the curriculum also draws on a wealth of evidence from social sciences and public health research. By grounding their curriculum in empirical data, the researchers ensure that the DEI principles taught are not merely theoretical but are supported by substantive findings. This connection to established research enhances the credibility of the curriculum and equips students with the necessary knowledge to adapt and respond to real-world challenges they will face as practicing psychiatrists.

The initiative has garnered interest not only from academic institutions but also from healthcare organizations seeking to implement similar models in their training programs. As awareness of health disparities continues to grow, the demand for educational frameworks that prioritize DEI will likely increase. By positioning their research at the forefront of this movement, the authors are poised to influence medical education and specialty training well beyond the confines of psychiatry.

Looking ahead, the authors envision the curriculum as a model for other disciplines within medical education, championing a cross-disciplinary approach that can be adapted to various specialties. This adaptability is vital as healthcare continues to evolve in response to an increasingly diverse patient population. The team hopes their work will inspire other medical schools to take proactive steps towards integrating DEI into all aspects of their curricula, fostering a culture of inclusivity across the entire healthcare system.

As the future of medicine depends on the ability to empathize with and understand the patient experience, the need for such transformative educational practices has never been clearer. By equipping future psychiatrists with the skills and knowledge to navigate complex human dynamics, this initiative stands to contribute significantly to the improved mental health and well-being of individuals from all walks of life.

In summary, the creation of a DEI curriculum for psychiatry rotations by Ondrey, Turk, Bydlon, and their colleagues represents a vital step towards reshaping medical education. At its core, this initiative not only addresses the importance of inclusivity but recognizes the profound impact that educational practices can have on the quality of healthcare delivered to diverse populations. By embracing the principles of diversity, equity, and inclusion, future psychiatrists will be better prepared to meet the challenges of an increasingly complex and diverse world.
