The IACVIRTUAL project has an Educational Module (that is based on Intelligent Tutor System) and a Decision Support Module that will use Case- Based Reasoning (CBR) to disease diagnosing and training of medical apprentice. This paper has as objective to present a CBR model in the context of this system. KEYWORDS Case-Based Reasoning. Virtual Medical Office. Decision Support System. Intelligent Tutor System. 1. INTRODUCTION Computer science has been recognized as an important component in the process of decision taking, supporting, particularly, the medical diagnostics and education. Nowadays, thanks to the advances of the Information Technology, there are diverse proposals of virtual environment for the integration of people with common interests. In the medicine field, this virtual space can be guaranteed through Virtual Medical Offices. The IACVIRTUAL project (Artificial Intelligence applied in the Modeling and Implementation of a
