This study sets out to investigate how the primary school students` sense of linguistic identity has changed since the 2000 survey in which early English learning raised a suspicion of weakening it. As a measuring factor of linguistic identity, attitudes towards mother tongue (Korean) was used in this study. The quantitative questionnaire survey was carried out with 128 students who were learning English at primary schools (of the same age and same schools as done before). For supporting the results of the questionnaire survey, the qualitative focus group interview was conducted with 6 primary school students. As a result of the quantitative survey, the participants did not show changes in attitudes towards their mother tongue and own culture compared to the 2000 survey. Rather, the perception of their mother tongue as a linguistic identity had been strengthened in the survey. The qualitative survey also supported the above results confirming that the participants had a positive attitude towards Korean and Korean culture. Therefore, this study suggests that early English learning does not lead to softening the learners` strong perception of their language.
