Why Schools Produce the Outcomes They Do
Medicine started as guesswork.
For centuries, physicians relied on observation, intuition, tradition, and treatments that often sounded reasonable but were poorly understood. Some interventions helped. Many did not. Some caused harm while attempting to heal. The problem was not that physicians lacked intelligence. The problem was not that they lacked commitment. The problem was that they lacked a governing principle. Over time, medicine evolved around a deceptively simple idea:
First, do no harm.
The phrase was never a promise of perfection. It was an acknowledgment of responsibility.
Before a physician prescribed a treatment, performed a procedure, or introduced an intervention, they were expected to consider a fundamental question:
Could the treatment itself be contributing to the problem?
That question changed medicine.It forced the profession to become more humble, more reflective, and ultimately more effective. Education has not yet had its equivalent moment.
We are a profession filled with people who care deeply about children. We innovate. We intervene. We assess. We remediate. We policy and charter. We accelerate. We reform. Every year new programs emerge. New initiatives are launched. New strategies promise better outcomes. Yet we rarely ask the question medicine eventually learned to ask:
What if the system itself is producing the outcomes we are trying to solve?
When students struggle, we study the student.
When teachers struggle, we study the teacher.
When schools struggle, we study the program.
Too rarely do we study the design.
And yet design is where the story begins.
There is a question I have carried for most of my career.
Why do some students spend their educational journey learning, while others spend their educational journey learning and learning how to navigate school? I noticed it first as a learner.
As a language learner, I often found myself working harder to access the same opportunities available to others.
As a neurodiverse learner, I learned that capability and access were not always the same thing.Years later, as a teacher, coach, and leader, I saw the same pattern repeated in schools across different communities, grade levels, and contexts. One learner is immediately recognized. Another must continually prove themselves. One learner encounters pathways. Another encounters barriers. One learner’s strengths are visible. Another learner’s strengths are obscured by the way the system is designed.
The difference is often described as achievement. Sometimes it is described as readiness. Sometimes it is described as motivation. But more often than we would like to admit, the difference is design
The longer I work in education, the more convinced I become of a simple truth:
Every system is perfectly designed to produce the experience it creates.
Schools are no exception.
This does not mean every outcome is intentional. It means every outcome is connected to a set of conditions. Students do not experience school through mission statements. They experience school through schedules. Through relationships. Through the curriculum. Through expectations. Through language. Through assessment. Through belonging. Through the thousands of decisions adults make every day.Over time, those experiences become outcomes. Which means outcomes are not mysteries. They are signals. They tell us something about the conditions that produced them.
The challenge is that many schools are designed around an imaginary learner.
A learner who arrives ready. A learner who learns through traditional methods. A learner who navigates language demands with ease. A learner who intuitively understands social expectations. A learner who can demonstrate understanding in predictable ways. A learner whose identity, culture, experiences, and ways of learning align naturally with the assumptions embedded within the system. That learner does not exist.
There is no average learner.
There are only learners. Each bringing different experiences, strengths, needs, identities, motivations, histories, and aspirations. Variability is not the exception. Variability is the rule. Yet many educational systems continue to treat variability as a problem to be managed rather than a reality to be designed for.
In product design, there is a concept known as designing for extreme users.
Instead of beginning with the average user, designers begin with the people whose experiences are most likely to reveal weaknesses in the system.
The curb cut is perhaps the most famous example.
Originally designed for wheelchair users, it ultimately benefited parents with strollers, travelers with luggage, delivery workers, cyclists, and countless others.
The design improved because it started at the margins. Education should operate the same way. The students who experience the greatest friction often reveal the most about the design of the system. The learner navigating multiple languages. The learner whose attention works differently. The learner questioning whether they belong. The learner whose strengths are not immediately recognized. The learner whose needs expose the assumptions embedded within the system. These learners are not exceptions to be accommodated. They are sources of insight. They help us see what others cannot.
This is why I believe education needs a professional principle of its own.
Not simply:
First, do no harm. But something more ambitious.
Above all else, design for the learner’s experience.
Before introducing an initiative, ask: Who might this exclude? Before implementing a policy, ask: Whose experience are we not considering? Before analyzing outcomes, ask: What conditions produced these results? Before asking learners to adapt, ask: What might the system need to become? These questions shift the work. From intervention to design. From compliance to belonging. From accommodation to access. From fixing learners to creating conditions where learners can thrive.
The schools that will define the future are not the schools that discover a perfect curriculum, a perfect program, or a perfect strategy. They will be the schools that understand a deeper truth: Outcomes are produced by conditions. And leadership’s most important responsibility is to design those conditions intentionally.
Not for the average learner. For the full range of learners. Especially those whose experiences reveal where the system still has work to do. Because when we design from the margins, we do not create better schools for some learners. We create better schools for everyone. And perhaps that is the principle education has been searching for all along:
Above all else, design for the learner’s experience.
