Abstract Background The Medical Students Non‐Technical Skills (Medi‐StuNTS) system is a behavioural marker system (BMS) designed to identify and debrief non‐technical skills (NTS) for medical students during immersive simulation. Educators must be adequately trained in using the BMS. This study aimed to design and implement an online platform to deliver a faculty development course on using Medi‐StuNTS and evaluate the feasibility of this platform in training faculty to identify and debrief NTS. Approach The online platform was developed by faculty with expertise in NTS, based on guidance for faculty training programme requirements and the multimodal model for online education. Content was arranged in modules, using presentations, videos of simulation scenarios and interactive discussion boards. Evaluation Fifteen participants completed the course and feedback over a two‐month period. A feedback form was completed to assess feasibility, based on a feasibility framework. The areas of focus were acceptability, demand, implementation, practicality, adaptation, integration, expansion and limited efficacy. Feedback indicated that the course shows promise in improving the ability of faculty to identify and debrief NTS. Implications The platform was successfully developed and implemented and was able to reach a national audience due to its online nature. Specific strengths include increased flexibility and accessibility compared to in‐person training. Feasibility assessment suggests that this newly developed online platform can work as an effective method for faculty development in order to increase skills in identifying and debriefing NTS using Medi‐StuNTS. Future work will focus on expansion of the online platform and dissemination to an international audience.
