For Alumni

Access to Online Content

For those who participated in the 2012 course, the majority of course content is now available on the password-protected TREE site.  This includes: webcast presentations, lecture slides, and recommended supplemental journal articles.  

If you have not already created an account on the TREE website, you will need to do so in order to gain access to these materials.  Please note that your account will need to be approved by the site administrator before your access to Principles Course material is activated.
