Adolescent language outcomes in a complex trilingual context: When typical does not mean unproblematic

This study examined the long-term language outcomes of adolescents in the complex multilingual context of Iceland, where children learn Icelandic as a first (L1) or second language (L2), in a background of incidental English from internet and media sources.

50 adolescents enrolled in grades 8, 9 and 10 in Reykjavik (Iceland) public schools (27 L1 speakers and 23 L2 speakers) participated. Standardized language tests and language samples were collected in Icelandic and English. Self-ratings and parent ratings of language proficiency were obtained in Icelandic, English and, for L2 speakers, in the home language as well.

As in previous studies, L2 speakers scored far below L1 speakers on formal tests of Icelandic, and also in conversation. The groups were similar in their English skills, with both groups scoring far below L1 English norms. Self-rated performance agreed well with measured performance. For the L2 speakers, self-rated performance in the home language was similar to performance in Icelandic and English. L1 speakers demonstrated much higher performance in Icelandic than English; L2 speakers' performance was more evenly distributed over their three languages.

The considerable English exposure available in Iceland leads to similar English skills for both L1 and L2 groups, but affects their overall language development in different ways. L1 adolescents maintain a clear dominance in Icelandic, whereas the proficiency of the L2 group is more equally distributed across their three languages, leading to unpredictable patterns of language dominance and at the group level, low performance compared to native speaker expectations in all three languages. These language outcomes in adolescence are of great concern as they do not equip the L2 speakers with the functional communication skills they require for further schooling and jobs. The study calls for a reconsideration of typical multilingual outcomes as necessarily implying unproblematic language skills and suggest that language policy changes are required in Iceland to ensure that children graduate compulsory education with solid language skills that allow them to pursue their goals.
