The 1^st level is divided in 3 separated modules with an exam at the end of each giving access to the following module. At the end of the first module the member will receive the title of Tecnico Assaggiatore (Technical Taster).

Once these steps are concluded, the candidate can attend a 2^nd level course, that will assign the title of Maestro Assaggiatore (Master Taster).

As part of the training process, ONAS organises refreshment courses, conferences and lectures in order to both improve the capability and knowledge of its members and to promote different Italian traditions.
