| Availability & practice | Available 24/7 with unlimited repeat attempts, so learners can practice as often as they need, on their own schedule, without waiting for a session.24/7; repeat anytime, as often as needed. | Practice is scheduled and episodic, limited by standardized-patient and faculty availability.Scheduled; limited by patient and faculty availability. |
|---|
| Feedback | Immediate, evidence-based feedback after every encounter, using a consistent assessment framework tied directly to the learner’s own words.Immediate, consistent feedback tied to the learner’s words. | Feedback quality depends on the debrief model in place and can vary by standardized patient or observer.Debrief quality varies by patient, observer and model. |
|---|
| Faculty time required | Minimal faculty involvement. Attempts, formative performance and trends are visible through a dashboard without faculty sitting in on each encounter.Dashboard review; no observer needed for every attempt. | Requires faculty or trained standardized patients to observe and assess in real time, which adds up across a cohort.Live observation and assessment required. |
|---|
| Cost to scale | Very low marginal cost to add another encounter or learner because there is no additional staffing requirement per session.Low marginal cost per learner or repeat encounter. | Each additional encounter adds cost through standardized-patient time, recruitment and training.Each encounter adds staffing and training costs. |
|---|
| Case variety & consistency | A large, growing case library with stable facts and configured difficulty across learners.Growing case library with consistent facts and difficulty. | Case portrayals can be excellent when well trained, with natural variability between standardized patients.High-quality portrayals with natural variation. |
|---|
| Longitudinal tracking | Improvement is tracked automatically across repeated attempts over weeks or months, without additional faculty data collection.Progress tracked automatically across attempts. | Tracking progress over time requires deliberate data collection and repeated assessments.Requires repeated assessment and separate data collection. |
|---|
| Physical realism | Voice-based encounters let the learner speak while the simulated patient responds with scenario-appropriate emotion, but there is no physical presence.Voice and emotion; no physical presence or examination. | Provides genuine physical presence, non-verbal cues and hands-on physical-examination practice.Physical presence, non-verbal cues and examination. |

| Best for | Frequent, low-stakes deliberate practice and coaching-style formative feedback.Frequent, low-stakes formative practice. | High-fidelity in-person encounters and summative assessment such as OSCEs.High-fidelity encounters and summative OSCE assessment. |
