Simulated Patient Educators Set Global Standards for Human-Centered Medical Training

A landmark set of professional standards for simulated patient methodology has just expanded its reach, with the Association of SP Educators publishing new best-practice standards for Physical Exam Teaching Associates, or PETAs. Writing as elected leaders of ASPE, the authors of a new editorial in the journal Advances in Simulation place this third standards publication in historical context, tracing how a methodology that began in the 1950s grew into a global framework that now guides how health professions educators recruit, train, and safeguard the people who portray patients for learners. The editorial, authored by Amelia Wallace, Cory Krebsbach, Janice Radway, and Lou Clark, argues that understanding the history of simulated participant methodology is essential to appreciating why safety and inclusion sit at the center of every standards document the association has produced.

Physical Exam Teaching Associates occupy a distinctive niche within simulation. Unlike standardized patients who typically portray a case from a script, PETAs use their own bodies as the teaching model, guiding learners through physical examination techniques while providing feedback on pressure, comfort, and scope from the patient’s perspective. The new standards outline global expectations for the professionals who work alongside PETAs, covering domains related to safety, development of sessions, training, and program management. The authors emphasize that the standards are designed to provide guidance while remaining flexible enough to accommodate the wide variation that exists in how the methodology is applied across different institutions and countries.

Central to all three of the association’s standards publications are two themes: inclusivity and psychological and physical safety for all participants, including the simulated patients themselves. Inclusivity, in this framework, means engaging simulated participants in sharing their perspective wherever possible, whether during case design or feedback sessions. The methodology asserts that the person who experienced the stimulus should have the most agency in articulating their perspective. The authors explain that this principle matters because the human component of simulation involves an individual who is neither clinician nor learner, and that position requires an intentional commitment to stewardship. SP Educators, the professionals entrusted with safeguarding and advocating for these participants, are described as integral to the process precisely because they protect the human voice while learners focus on clinical technique.

The history of the methodology reaches back to the 1950s, when physicians Howard Barrows and Paula Stillman are credited with its innovation. The editorial highlights a largely unacknowledged group of interdisciplinary professionals, now known as SP Educators, who worked alongside Barrows and Stillman from the beginning. Their vision and resilience, the authors write, catalyzed the profession of SP education into existence throughout the 1980s and 1990s, ultimately leading to the formation of the Association of SP Educators itself.

A pivotal moment arrived in the 1990s and 2000s, when the concept of people without clinical backgrounds engaging in the educational process was galvanized by the adoption of simulated patient methodology as an element of national licensing examinations for learners in Canada and the United States. While North American educators concentrated heavily on summative assessment, international applications ranged far more widely, producing a variety of uses and an extensive lexicon of terms. The profession’s expansion generated a proliferation of labels for the people involved in human simulation, including role-players, patient instructors, programmed patients, teaching associates, simulated patients, standardized patients, simulated participants, patient teachers, and patient educators.

The first formal standards arrived in 2017, when a team led by ASPE past president Karen Lewis finalized the initial iteration of the ASPE Standards of Best Practice, published in Advances in Simulation under editor-in-chief Debra Nestel. Since then, the document has become widely cited and serves as the foundation for related advances in the field. It has been translated into multiple languages and is currently undergoing its first major revision, with an anticipated publication date of 2026. The standards are organized around five domains: safety, case development, training, program management, and professional development. These are undergirded by five values: safety, quality, professionalism, accountability, and collaboration.

The reliance on the original standards in the literature inspired ASPE members, led by past president Gayle Gliva-McConvey, to develop a book titled Implementing Best Practices of Standardized Patient Methodology, published in 2020 as part of Springer’s Comprehensive Healthcare Simulation series. Each chapter of that edited volume is framed by the five domains and grounded in the five values, and contributions came from ASPE members around the world.

In 2024, a team of ten international leaders in SP methodology and research, led by ASPE immediate past president Lou Clark, published an editorial described as a landmark call to action, urging the global simulation community to honor simulated participants and collaborate with their educators.
