In September 2012 the Australian Industry Group (Ai Group) contracted the Australian Council for Educational Research (ACER) to conduct this study into the financial return to employers from investing in workplace literacy training programs. The Australian Government, through its Department of Industry, Innovation, Science, Research and Tertiary Education (DIISRTE), contracted the Australian Industry Group (Ai Group) to manage the project. Over 2013-14, this study developed and trialled a set of data collection instruments in pilot mode with seven training programs funded under the Workplace English Language and Literacy (WELL) program. This report presents the results from the study in the form of case studies (Chapter 5), drawing on an extensive literature review (Annex 4) and mapping of similar evaluations in Australia and overseas (Annex 5).
