This study examines the relationship between performance and knowledge of three rehabilitation multidisciplinary (RM) groups during a Mock Harvey Team (MHT) after simulation of life‐threatening patient situation. It was hypothesized that with initiation of Mock Harvey Team inservice training, the quality of the RM groups' performance would be enhanced, and with inservice education on identified problem areas, the professional care givers would evidence increased knowledge and added performance skills during an MHT clinical experience. Each of the three groups that participated in the MHT was composed of 11 participants from a variety of disciplines. They were evaluated on equipment and drug performance and knowledge. Evaluation tools used were direct observation and checklist evaluation. Problem areas were identified, and inservice programs were held that focused on priority tasks. The MHT simulations were repeated after the RM groups completed a series of inservice programs. The checklist evaluation reflected an increase in MHT performance and knowledge. It was concluded that the RM members of each group were more knowledgeable and exhibited improved performance during the MHT simulation
