The previous post in this series on formative assessment in medical education drew a distinction between administering assessments and designing them to actually function formatively. Feedback faces the same problem and arguably a more persistent one. You know feedback should be specific, timely and actionable. The harder question is why, even when it is, your students so often don't do anything with it.
And it's worth saying upfront: this isn't primarily a student problem. It's a structural one. The conditions under which feedback is delivered, received and followed up on shape whether it drives learning — and those conditions are frequently misaligned with what the research tells us works.
Timing isn’t a logistical default.
There's a widespread assumption that faster feedback is always better. The reality is that timing should be a deliberate design decision matched to the task, not a default driven by scheduling convenience.
For procedural or skill-based tasks, immediate feedback helps learners connect the response directly to the behavior while the experience is still fresh. Debriefing right after a simulation or OSCE station is often the right call; the learner can map the feedback onto what they just did, and the correction is more likely to transfer.
For complex clinical reasoning, the dynamic shifts. A brief delay, even just a day or two, often allows learners to reflect on their own performance before receiving external input. That reflective interval tends to produce deeper cognitive processing and more durable change than feedback delivered before the learner has had a chance to form their own assessment.
Specificity is where most feedback fails.
Generic feedback — "good job," "needs improvement," "work on your communication" — is one of the most consistent failure points in formative practice. Comments like these don't give your learners a path forward. They describe a verdict on the past without pointing toward a concrete next step.
Effective feedback identifies a specific behavior, explains why it matters and indicates what the learner should do differently. "Your differential was too narrow; consider a broader range of possibilities and use more diagnostic tests to rule out alternatives before committing to a diagnosis" gives the learner something to act on. It connects the gap to the competency and provides direction, which is what moves feedback from judgment to instruction.
This level of specificity also requires that feedback be explicitly tied to learning objectives. When a learner understands not just what went wrong but how it relates to what they're working toward, the feedback becomes easier to prioritize and act on.
The feedback sandwich isn't helping.
One of the most persistent structural problems in medical education feedback is the continued use of the feedback sandwich — bracketing critical feedback between two layers of positive comment. The intent is to maintain motivation and soften criticism. The evidence suggests it frequently does the opposite.
When feedback opens with praise, learners tend to anchor on it. They leave the conversation with a more favorable impression of their performance than the feedback actually warranted, a well-documented anchoring effect that limits their motivation to change. The critical content in the middle gets diluted, not because your students are resistant, but because the structure itself undermines the clarity of the message.
More effective is direct, specific feedback that addresses areas for improvement without artificial framing while still acknowledging genuine strengths when they exist. The goal isn't harshness — it's honesty and clarity. Research suggests learners find direct, specific feedback more useful and more sincere than praise-padded critiques they have to decode.
Feedback without follow-through doesn’t work.
Even well-constructed, well-timed, clearly delivered feedback can fail to produce change if it isn't connected to a subsequent opportunity to apply it. Feedback tells a learner what to do differently. Without a chance to practice the corrected behavior, receive another signal and close the loop, the learner can’t effectively use the feedback.
This is where self-reflection becomes critical, not as a soft add-on, but as a structural component of the feedback process. Structured self-reflection tools — journals, guided self-assessment forms, annotated examplars, detailed rubrics — give your learners a scaffold for doing this work. They also help calibrate self-perception against objective criteria, which matters because uninformed self-assessment is frequently inaccurate. Learners who reflect with reference to explicit standards are better positioned to act on feedback than those evaluating their own performance without guidance.
"Self-reflection is the culmination, the core, the heartbeat of assessment for learning, because what we want our learners to be able to do is to take a pause, evaluate where they are, think about where they need to go, and then formulate a strategy on how to get there or seek help."
~ Anastasiya Lipnevich, PhD, Principal Measurement Scientist at NBME
Feedback is most effective when it initiates a cycle — feedback, reflection, practice, feedback again — rather than functioning as a one-time event. Building that cycle into program design, rather than leaving it to individual instructors to improvise, is what makes feedback reliably formative.
What this means in practice
Fixing a feedback system that isn't working requires looking beyond the quality of individual feedback exchanges and asking whether the system as a whole is designed to support your students’ learning. That means:
Being deliberate about timing
Setting a standard for specificity and tying feedback consistently to learning objectives
Retiring the feedback sandwich in favor of clearer, more honest deliver
Building in structured opportunities for reflection and follow-up practice as core components of the assessment design
These aren't dramatic interventions. They're design decisions, and making them intentionally is what separates a feedback system that works from one that doesn't.
There's also real nuance in how feedback lands differently depending on context, source and the individual learner — factors that shape receptivity in ways that aren't always visible to you as the instructor. Our article on how guided reflection and thoughtful feedback shape empathetic clinicians goes deeper on these dynamics, with particular attention to communication skills, where what's being assessed is less procedural and harder to observe. Our downloadable Meeting Learners Where They Are guide offers a practical companion — concrete strategies for designing assessment and delivering feedback across each of these dimensions.
For programs focused specifically on communication skills, the Communication Skills in the Age of AI webinar explores how tools like our Communication Learning Assessment (CLA) can provide your students with structured, low-stakes opportunities to practice and receive feedback, building the kind of iterative practice loop that makes feedback stick.
