This study investigates individual factors and workplace practices associated with self-perceived communication competence in the workplace (SPCCW) at a university in Norway. Via an online survey, 313 international academic staff members reported their SPCCW in Norwegian as a second language (L2). Although 92% of the permanent staff who responded reported having taken formal training in L2 Norwegian, only 54% of these felt that they knew enough Norwegian to perform their work effectively. Findings showed that, in addition to length of residence in Norway, having a Germanic first language (other than English) was a significant predictor of SPCCW. Qualitative comments indicated that activities in Norwegian outside of work and having patient interaction partners to practise with were perceived as beneficial for L2 confidence in the workplace. The findings are discussed from a second language acquisition perspective and add to our understanding of how the language competencies needed for work in higher education can be developed.
