The aim of this sub-module is to help small and medium-sized enterprises (users) understand the role of the data protection officer in the organization/company, the situations in which his mandatory appointment is prescribed and his characteristics and duties, as well as the obligations of the organization/company in relation to him. After reviewing the video and the theoretical part, users will be able to answer questions to check their knowledge. The user will be offered statements, in respect of which he/she will be able to state whether he/she considers them true or false. Once the user has answered the answers, an explanation of the correct answer will appear. If the user achieves a minimum of 80 % correct answers, then the system will generate a certificate as proof of successfully passing the theoretical sub-module.
