The "National Science, Technology, Engineering and Mathematics (STEM) School Education Strategy 2016-2026" (the National Strategy) supports a long-term change agenda aiming to ensure that students have a stronger foundation in STEM and are inspired to take on more challenging STEM subjects. The National Strategy acknowledges that there is significant effort already underway within all jurisdictions to lift student outcomes in STEM. A national focus on STEM education aims to better coordinate this effort and target the key areas where collaborative action can provide fresh momentum to improve student participation and performance. The National Strategy sets out two high level goals: (1) Ensure all students finish school with strong foundational knowledge in STEM and related skills; and (2) Ensure that students are inspired to take on more challenging STEM subjects. For this project, the Australian Government, with partners South Australia, Victoria and Education Services Australia, sought information from all jurisdictions on STEM-related initiatives, with a focus on those that had completed or planned evaluations, and where available, the research and evaluation results. The project aims to build an evidence base to guide policymakers on what approaches work best for different purposes and circumstances. The information in this report provides a summary of the initiatives nominated by jurisdictions including a description of the scale, target group/s and program objective; and information on how well the initiative has achieved its goals, including external evaluation data if such data are available. The aim of this report is to share information about existing STEM initiatives, including evaluation findings, to establish a stronger evidence base to improve our understanding of what STEM initiatives work in Australian contexts.
