Between 2011 and 2014, DAAD lectors from the three baltic states carried out a study under the topic "Language learning motivations for (potential) German learners in Estonia, Latvia and Lithuania"
As the title gives away, the main aim of the study was to determine the motivations German learners had for their studies - or alternatively, why these people didn't study German anymore, or never even started.
Methodically, the study was carried out both by means of qualitative preliminary talks with experts and focus groups, as well as quantitative surveys. Some participants were also invited to follow-up discussions.
The results show that German generally enjoys a good reputation in the Baltic states. It's frequently viewed as the most important foreign language to learn after English, and on the same standing as Russian. Many view German language studie as unusually challenging, however. Historical arguments for or against German language studies, on the other hand, play almost no role for most Baltic people.
