The aim of this twinning project was to strengthen the administrative capacity of the Lithuanian State Data Protection Inspectorate (SDPI) to implement the data protection acquis and to enable the Inspectorate to work according to the good practice of Austrian and German Data Protection Authorities. In order to achieve this goal, the practice of the SDPI in certain areas of work was analysed and recommendations were provided. To increase the general knowledge on data protection in the Beneficiary Country, the specialized training packages were elaborated. Furthermore, inspectors of the SDPI received training at data protection institutions in Member States. To facilitate the day-to-day work of the SDPI, an analysis on the Lithuanian Data Protection Law was prepared.
