GMU Salary Schemes

I've been told by several people who track GMU salaries that I'll never get close to the real information about what certain people are paid at GMU. While the salary information that GMU provides me is probably correct in that those payments are made to employees, there are various "special deals" cut for select people that continue to go unreported.

These "special deals" are additional payments that originate from alternative funding sources that GMU does not report when asked for salary information. They include:

Someone shared administrative-only published information suggesting that the Dean of the GMU law school makes more money than is disclosed on FOIA requests. I have no way to verify that, but administrators and faculty can access the published information on the faculty senate website and make their own guesses about why GMU discloses different salary figures and whether there are unconventional ways salaries are computed for different audiences.

The information I was sent claims Daniel Polsby's actual salary history is:
2000 2001 2002 2003 2004 2005 2006 2007 2008
187,000 187,000 187,000 194,500 198,876 225,327 301,600 313,664 325,583

The information GMU provided to RobLINK in response to FOIA requests (Spring semester data) was:
2000 2001 2002 2003 2004 2005 2006 2007 2008
180,500 187,000 187,000 194,500 198,876 290,000 301,600 313,664 272,019

Since the data published on this site is provided by GMU, I have no way to obtain alternative authoritative data or explain variations with data GMU publishes elsewhere. Perhaps they have "special deals" that provide payment through alternative methods that are not disclosed when they are required to release salary information.

If you have alternative answers or elucidating information to share, please get in touch.
