To acquire essential knowledge and skills for Public Health practice, residents in Hygiene and Preventive Medicine programs should be provided with excellent training. On behalf of the Roman Public Health Academy (ARSP), the authors, representing the three Hygiene and Preventive Medicine residency training programs in Rome (Italy) aimed to propose a training program to be shared by the above three schools. Firstly, they performed a scientific literature review to identify the core competencies that a public health specialist should have acquired at the end of training. Ten areas (macro-areas or domains) relevant to Public Health practice were defined. The authors then identified the main characteristics that the proposed training program should have, which include: enhancement of community healthcare services and optimization of local resources to create/strengthen exchange and cooperation networks; possibility to adapt the training proposal to an international setting; adoption of a training approach that can respond effectively to a changing health system; customization of training on the basis of residents' individual abilities and motivations, so that their individual strengths can be enhanced; achievement of educational excellence, in compliance with ethical requirements.
