The Hidden Curriculum Has a Hidden Cost

How Nursing Education Inadvertently Excludes Diverse Minds

Your Classroom Has an Operating System You Didn’t Write

The hidden curriculum is not a new concept in nursing education. Research by Abbaspour and colleagues (2022) found that the hidden curriculum shapes learners’ professional identity, values, and role understanding. Its unexamined negative consequences include loss of confidence, incivility, negative role modeling, and the erosion of human values. A 2025 study by Doğan et al. found that negative hidden curriculum experiences correlate directly with lower education satisfaction and a higher likelihood of workplace harassment.

When the hidden curriculum operates without examination, it does not produce neutral outcomes. It produces a predictable sorting effect: learners whose neurotype, communication style, or processing pattern aligns with the unwritten norm move through it relatively unscathed. Learners whose brains work differently pay for an expectation that was never disclosed to them.

And those learners are not rare. Cummings et al. (2026) found that roughly one in five undergraduate learners across disciplines is neurodivergent, encompassing ADHD, autism spectrum disorder, dyslexia, dyspraxia, and sensory processing differences. In a cohort of twenty nursing learners, that is three or four people navigating a learning environment that may have been designed, without anyone’s intention, to work against them.

The Neuroscience of Belonging

Here is what happens in the brain when the hidden curriculum lands.

David Rock’s SCARF model (2008) identifies five domains of social experience that the brain treats with the same urgency as physical survival: Status, Certainty, Autonomy, Relatedness, and Fairness. Relatedness — the sense of belonging and connection — is the domain most directly threatened by the hidden curriculum. When a learner feels misread, othered, or penalized for the way their brain naturally operates, the Relatedness domain triggers a threat response.

Eisenberger et al. (2003) demonstrated that social exclusion activates the same pain pathways as physical injury. When belonging feels uncertain, the threat response fires and the prefrontal cortex goes offline, taking clinical reasoning and critical thinking with it.

We cannot teach into a threatened brain. The learner who cannot find their way into the classroom discussion may be trying to learn under a threat load their nervous system was never designed to absorb silently.

The Most Misread Behavior in Clinical

Move the scenario to the clinical floor. The dynamic shifts, but the mechanism stays the same.

Research by Adolph and West (2022) challenges the assumption that eye contact avoidance signals disengagement. Both autistic and typically developing children focused primarily on objects rather than faces during naturalistic play. Eye contact avoidance is a diagnostic marker used in clinical assessments of autism. It is not a reliable indicator of engagement, motivation, or competence in everyday interaction.

The preceptor’s read of “not paying attention” may have been a neurotype mismatch, not a clinical observation. And when that misread becomes part of a written evaluation, it becomes part of the learner’s record.

Research by Sharfi et al. (2022) found that learners managing high levels of sensory input have measurably fewer cognitive resources available for task sequencing, working memory, and verbal response. A learner filtering cardiac monitor alarms, overhead paging, simultaneous conversations, and competing smells is not distracted. Their brain is working — just on something the preceptor cannot see.

Start there, and the evaluation looks different.

The Environment Creates the Disability

Universal Design for Learning (UDL), developed by CAST, shifts the work from the learner to the design. It is built on three principles tied to three brain networks: Engagement (the why, affective networks), Representation (the what, recognition networks), and Action and Expression (the how, strategic networks). The question UDL asks is not “how do we accommodate this learner?” It is “how do we build an environment that anticipates the full range of neurotypes from the start?”

We did not add ramps to existing buildings as a special feature for a few users. We redesigned buildings with ramps from the start, because ramps serve parents with strollers, delivery workers, aging adults, and anyone navigating an injury. That is built-in design. And it is better design for everyone.

One environment, calibrated to serve a broader range — not individualized plans for thirty learners.

The same principle applies to the nursing classroom. An anonymous pre-course survey asking about sensory and environmental needs is not accommodating one learner. It is designing better. Forthun (2025) describes a nursing cohort where a simple pre-course survey revealed significant variation in lighting sensitivity, activity preferences, and learning formats — an educator who redesigned for all three at once.

Three Starting Points for Nurse Educators

Audit one policy before you audit anything else.

Look at how you define engagement in your classroom. If the unspoken expectation is that engaged learners speak up, volunteer answers, and participate in the visible flow of discussion — ask yourself what that privileges. The learner who processes in writing, who comes alive in small groups, or who needs a few extra seconds before they can respond may be fully engaged. Just not in the way the room was set up to recognize. Offering more than one way to demonstrate presence is not lowering the bar. It is moving the bar from “who engages this particular way” to “who engages.”

Replace one behavioral assumption with a curiosity question.

The preceptor who asks “why won’t they look at me?” and the preceptor who asks “what might their brain be managing right now?” are starting from different neurosciences. One activates judgment. One activates coaching. Before your next clinical evaluation, try: “I noticed you tend to look away during handoff. Can you help me understand what’s going on for you in that moment?” That sentence moves the learner from threatened to seen. It gives you information instead of a misread.

Add one UDL adjustment to your next class session.

Wherever you currently require one format to demonstrate understanding, offer two. If the learning objective is “demonstrates understanding of fluid balance,” a written analysis, a concept map, and a verbal case discussion are all valid evidence. The format is not the point. The competence is. When the format is not the learning objective, it should not be the barrier. Design for the edges of the population, and you improve conditions for everyone in the middle.

Why This Matters Beyond the Classroom

The case for equity in nursing education is a workforce argument and a patient safety argument. The Future of Nursing 2020–2030 report is plain about it: achieving health equity requires a diverse nursing workforce, and that workforce requires inclusive learning environments to grow. The profession’s major organizations have said the same.

We cannot build a workforce that serves diverse patients if we exclude diverse minds while they are still in training. Research by Carter (2020) shows that racial and ethnic minority nurses are more likely to return to and serve underrepresented communities, bridging cultural and linguistic gaps that directly affect patient outcomes. A diverse nursing workforce is a patient safety strategy.

The classroom that inadvertently excludes diverse brains is producing nurses who learned, quietly, that certain brains belong in nursing and certain brains do not. That lesson travels straight to the bedside.

Conclusion

Go back to the educator at her desk, reading through those anonymous evaluations.

She built a discussion-based classroom because that is how she learns, how she processes, how she came alive in her own training. She assumed her learners would too. She did not consider that the classroom she found so alive might feel, to other brains, like a room with a door they could not open.

The learner who wrote “I always knew the answer — just not quickly enough” sat in that room all semester. Present. Working. Excluded not by the content, but by the pace.

The hidden curriculum has a cost. It is not paid equally. Examining it is how you start to change that.
