SEPI-SIM: An Educational Architecture for Longitudinal Competency Development in Simulation-Based Health Professions Education
The paper introduces SEPI-SIM, a four-phase educational architecture that integrates competency-based education, simulation, programmatic assessment, structured feedback, and learning analytics to transform fragmented educational activities into a coherent longitudinal system for evidence-informed decision-making in health professions education.

In the high-stakes world of training doctors, nurses, and other healthcare professionals, the goal has shifted from simply counting the hours a student spends in a classroom to measuring what they can actually do. Modern medical education relies heavily on simulation, where learners practice skills in safe, controlled environments before ever touching a real patient. This approach is paired with competency-based learning, which focuses on mastering specific abilities like clinical reasoning or teamwork rather than just passing a test at the end of a term. Educators also use structured feedback, where instructors guide students through a careful review of their performance, and learning analytics, which involves tracking data over time to spot patterns in how students learn. While each of these tools is powerful on its own, they often operate in isolation. A student might practice in a simulation, receive a grade, get some feedback, and have their data recorded, but these pieces of information rarely connect to tell a complete story about their growth over months or years. This fragmentation makes it difficult to see the full picture of a learner's development or to make informed decisions about how to improve the curriculum.
To solve this problem, researchers Hugo Berríos-Arvey and Evelyn Cisterna-Vega from Universidad San Sebastián have designed a new educational framework called SEPI-SIM. This is not a new type of medical simulation or a specific test; rather, it is a blueprint for how to organize existing educational tools so they work together as a single, continuous system. The researchers developed this architecture by reviewing thousands of studies published between 2010 and 2024, looking for the most effective ways to teach and assess medical skills. They found that the most successful training programs rely on five key areas: competency-based education, simulation-based learning, programmatic assessment (which uses many small assessments instead of one big exam), structured feedback, and learning analytics. The challenge was that these areas were usually treated as separate departments. SEPI-SIM weaves them together into a four-step cycle that runs throughout a student's entire education.
The process begins with a diagnostic assessment, where educators figure out what a student already knows and what they need to learn before they even start a simulation. This creates a baseline profile for each learner. Next, the student enters the simulation phase, where they practice in scenarios that get progressively harder. Instead of just passing or failing, their performance is measured repeatedly using detailed checklists and rubrics that track specific skills like communication, technical ability, and decision-making. After every simulation, the third phase kicks in: structured feedback. Here, the student and instructor engage in a guided conversation to reflect on what went well and what needs improvement, turning the assessment into a learning moment rather than just a judgment. Finally, the fourth phase uses learning analytics to gather all the data from the previous steps. This information is compiled into a long-term record that shows how the student is progressing over time, allowing educators to spot trends, identify students who might need extra help, and adjust the curriculum to better suit the group's needs.
The core idea behind SEPI-SIM is that assessment should not be a series of isolated events but a continuous stream of evidence. By connecting the initial diagnosis, the practice sessions, the feedback conversations, and the long-term data tracking, the system creates a coherent narrative of a student's journey. This approach ensures that every simulation activity contributes to a larger understanding of the learner's capabilities. The researchers emphasize that this framework is designed to be flexible and transferable, meaning it can be adapted to different medical schools and training programs. It transforms the chaotic collection of grades and notes into a clear, organized system that supports both the individual student and the institution running the program.
However, the authors are careful to note that SEPI-SIM is currently a theoretical model, a design based on existing evidence rather than a system that has been fully tested in real-world classrooms. While the logic is sound and grounded in established educational principles, the framework has not yet been proven to work in practice across different institutions. The researchers acknowledge that future studies are needed to see if this system actually improves student outcomes, how well it fits into existing schedules, and whether the tools used within it are reliable. They also point out that schools will need to adapt the model to their specific resources and technologies. Despite these limitations, the proposal offers a clear path forward for a field that often struggles to connect the dots between teaching, testing, and learning. By providing a structured way to integrate these elements, SEPI-SIM aims to turn the fragmented pieces of medical education into a unified system that truly supports the development of competent, confident healthcare professionals.
