Present research is based on source materials which point at the importance of education in mother tongue to Poles inhabiting Lithuania in preserving their national identity. At the same time they disprove the thesis about the polonization of Vilnius region, which allegedly took place during the Soviet period as a result of the government’s permission for the existence of schools teaching in Polish. The percentage of students receiving education in the Polish language was always lower than the percentage of Poles inhabiting Lithuania. However, the process of russification was pressed in Vilnius region, which was stopped by regaining of the independence by Lithuania. Poles, who won the right to education in mother tongue in 1950s, in independent Lithuania opted for a traditional model of school with education in mother tongue as well. More and more students were receiving education in schools teaching in Polish, also the number of school leavers continuing studies at universities was increasing.
