Many second language (L2) students in Sweden struggle with reading in Swedish. There needs to be more research on how L2 students with weak word decoding skills in Swedish could be individually supported. Therefore, the current study examined the impact of a systematic and intensive word decoding intervention in Swedish among individual L2 students identified as having a risk of reading difficulties in Grade 3. A multiple-baseline single-subject design study was conducted with three L2 students with Arabic or Dari as their first language. They were provided a word decoding intervention with Bravkod. All three students improved their decoding during the intervention phase. They decoded several words in a given time (NAP=0.96-1.00) and decreased their word decoding errors (NAP=0.91-0.98). The results are promising but should be replicated to be considered evidence-based and suitable for L2 students to improve their decoding in Swedish.
