The training requirements of foreign-born workers may be different from those of native-born workers in similar jobs. Over recent decades Australian immigration policy has focused predominantly on accepting high-skilled migrants. Although this focus has resulted in the successful integration of foreign-born workers into the Australian labour market (Chiswick & Miller 2011), high-skilled migrant workers may require further training to upgrade their skills for high-skilled employment. Against this backdrop, this study examines the relationship between training requirements and the migration background of workers in four (mainly) English-speaking countries (Australia, New Zealand, the United States and Canada). The authors are particularly interested in the extent to which the training requirements of foreign-born workers differ from those of native-born workers, and the extent to which these requirements are met in each of these countries. They pay particular attention to the differences between native English-speaking and non-native English-speaking workers within migrant populations because it seems likely that these groups have very different training requirements. They analyse the relationship between adult literacy skills and a skill use measure that reflects the frequency with which workers undertake certain tasks in their jobs. Analysing this relationship allows them to draw inferences about the need for further training among certain groups of native- and foreign-born workers in each country. The results obtained from this analysis are then compared with an analysis of the determinants of the actual training participation of native- and foreign-born workers. Their empirical findings reveal that foreign-born workers in Australia usually seem to receive the training they need, indicating that the integration of foreign-born workers into the Australian education and training system has been successful. While training requirements are being met in a similar way in the US and Canada, the authors observe that foreign-born workers in New Zealand are significantly more likely to require further training, but do not receive significantly more training than comparable native-born workers.
