Defining performance standards for the next generation of surgeons

Procedural Learning and Safety Collaborative (PLSC) is a non-profit research consortium focused on investigating and developing tools, curriculum, and policy to improve the training of surgical and other procedural physicians.  The collaborative was founded by experts in surgical trainee performance assessment with the initial support of Massachusetts General Hospital, Northwestern University, and Indiana University.  We are now funded by our institutional members and grants.  Our passion is to investigate and combine innovative curricula, best-practice evaluation methodology, consulting services, and state-of-the-art technology to improve the training of residents in Surgery and other procedural specialties.
