At the OpenEd Conference in 2013, Nicole Allen and David Wiley challenged the OER community to save students one billion dollars. Five years later, SPARC have collected a significant amount of data in order to answer the question of whether or not that goal has been achieved. You can read more about the data collection methodology and their ongoing work on this question here. SPARC have made the data available under a CC0 license and you can download them here. David Wiley's report is available here.
