The Swedish National Board of Education studied 7,095 youth (mostly immigrants) who were in grade 9 of compulsory school in 1978-79 and who spoke a language other than Swedish at home. The part of the study reported on here focused on the concern that young immigrants leaving compulsory school tend less frequently than Swedish pupils to go on to (voluntary) upper secondary school. In 1979, study results indicated an average of 69% of pupils with other home languages (compared with 80% of Swedish home speakers) went straight on to upper secondary school. Pupils with other home languages who nontheless had a strong command of Swedish went on to upper secondary school with nearly the same frequency as Swedish home speakers, but pupils with less of a command of Swedish had lower average marks when applying for upper secondary school. However, those not having a command of Swedish comparable to Swedish pupils' represented a minor proportion (17%) of all pupils with other than home languages. Similarly, in the area of choice of line of studies, other home language students with a strong command of Swedish were more likely than those with less Swedish ability to choose a line similar to that of Swedish home speakers. In grade 9, 75% of pupils who had a lower command of Swedish attended auxiliary Swedish lessons. And finally, only a small proportion of the over 2,000 pupils with other home languages who did not go straight on to upper secondary school in 1979 participated (1979-80) in one of the introductory courses designed to make it easier for young immigrants to embark on upper secondary schooling.
