• Face-to-face lectures
• Exercises (exercises, database, software etc.)
• Case studies /Incidents (traditional, online)
• Group assignments

The course is located in a computer room in order to provide a hands-on approach to credit risk models building and validation. This feature of the course is based on lectures, in-class exercises, incidents and case studies, both as individual or small-groups work. Almost each topic involves (class or home) exercises and incidents. A unique case study, based on a real world database of SMEs financial data, is used for building and validating a statistical based rating system during many class sessions; SPSS is used as statistical tools, because it is used in real world risk departments, it is quite friendly also for newcomers, and the textbook published by Wiley is based on the same case study and SPSS application . IBM-SPSS will be download on students laptop by Bocconi help desk facilities. A group assignment is optional; each student in a group may earn from 0/30 to 2/30 additional points to those earned in the written exam.

• A written exam based on three short essays tries to check the proper understanding of areas of credit risk management that have been covered in class. The final mark is expressed in thirties (X/30).
• A group assignment is optional. Each student in a group may earn from 0/30 to 2/30 additional points to those earned in the written exam; these additional points can be used up to the end of September 2023. The group assignment is devoted to enhance not only how-to-do capabilities, but also team management, project management and (written) presentation skills.
