Prebriefing
Prebriefing is everything a program does before a simulation scenario starts to get learners ready for it, and the INACSL standard splits it into two parts: preparation, which situates learners in a common mental model and readies them for the educational content, and briefing, which conveys the ground rules of the encounter. Its stated purpose is to establish a psychologically safe learning environment, so prebriefing is the point where a program earns the candor it later wants in the debrief. INACSL published it as a standard in its own right in 2021, having previously folded the preparation half into simulation design.
The standard exists partly to settle a vocabulary problem. Before 2021 the literature used prescenario learning activities, pre-planning sessions, briefing, preparation, presimulation preparation, presimulation briefing, and presimulation assignments to describe overlapping work, which made it hard for two centers to compare what they actually did. INACSL now uses prebriefing as the single umbrella term for all activities occurring before the scenario, then divides it into preparation and briefing so that each half can be planned and audited against its own criteria.
Preparation is the content side. It carries the reading, the case background, any prescenario activity, and the role modeling or expert modeling that some centers build in, and the standard frames the goal as balancing the learner's cognitive load so attention is available for the scenario itself. Briefing is the contract side. It covers the objectives, the environment, the roles, confidentiality, the time available, and how the encounter will be evaluated. For summative or high-stakes simulation the standard adds a specific requirement to tell learners in advance what type of scenario they will face and how they will be assessed, which is the difference between a fair examination and an ambush.
The general criteria hold the simulationist to the same bar as the debriefing standard. The person running the prebrief needs to be knowledgeable about the scenario and competent in prebriefing concepts, the prebrief has to be developed from the purpose and learning objectives of the experience, and the learner's own experience level has to shape it. A first-year resident meeting a family in crisis for the first time and a fellow rehearsing the same conversation need different preparation, and the standard treats that difference as a design decision rather than an accident of the schedule.
The connection to what happens afterward is direct. Rudolph, Raemer, and Simon argue that the presimulation briefing is where instructors build the safe container that lets learners take intellectual risks, and their practices include the fiction contract, the agreement that everyone will treat an imperfect simulation as if it were real. Programs that skip the fiction contract tend to spend the first third of the debrief arguing about realism instead of about the encounter.
What this looks like in a program
- Write the prebrief once per scenario and reuse it, so every learner gets the same objectives, ground rules, and confidentiality promise regardless of which faculty member is running the session that week.
- Say out loud whether the encounter is formative or graded. Learners who suspect a hidden assessment perform for the rubric instead of engaging with the patient.
- For asynchronous practice with AI patients, put the prebrief on the screen before the encounter opens, since there is no facilitator in the room to set the frame.
