Internet2 has recently updated its "The State of the Program: Identity and Access Management Self-Assessment" tool. This resource can help measure the maturity of your campus IAM program and identify areas of strengths and potential weaknesses to be remediated. Plus, it's free to use (but just as well-researched and applicable as similar commercial assessment tools and services). From the document:
This assessment is...a tool meant to help you identify the maturity of your IdM processes and infrastructure. It defines the characteristics of each maturity level in order to help you develop your IdM program with federation as the goal. It is likely that your institution may be at different maturity levels for the process or infrastructure of any given function.
