Two weeks ago, IPPR\u2019s Commission on the Future of Higher Education published its final report \u2013 A Critical Path. There has already been a lively debate on these pages about some of the key findings of the report. Most recently, Andrew McGettigan posted some detailed technical criticisms about how IPPR\u2019s report treated the higher education funding system. This debate is very important because some of the details are critical to understand as they affect current and future policies. This piece will seek to answer Andrew's criticisms, and take the debate another step forward.
