Sweden's flagship: free municipal Swedish tuition for every adult immigrant.
Details
Skolverket (the National Agency for Education) sets the national SFI curriculum, and each municipality delivers the actual courses through its komvux. Open from age 16 to anyone living in Sweden who lacks basic Swedish, structured as four sequential courses A to D including literacy training, individually adapted to your prior schooling and goals. Tuition is free. This is the authority's page rather than an application form — apply through the municipality you live in (see the Stockholm and Gothenburg entries below).
