Hello Henry,
I dont have any evidence on grades and success, but a newly published 2006 Book, New Visions of Graduate Management Education by Charles Wankel and Rober DeFillippi (Greenwich, CT: Information Age Publishers) features a chapter by Edward J. Inderriiden of Marquette U. and Brooks C. Holtom of Georgetown University on the positive impacts of MBAs on income earnings .
Their chapter uses a panel study to compare two subsamples of GMAT test takes : those who complete an MBA and those who do no. They find that completing an MBA among GMAT test takers (controlling for cognitive ability and demographic factors) yields a positive income benefits when the two subsamples are compared in terms of their absolute income gains and percentagage income changes between taking the GMAT in 1990 and the their incomes in 1998.
They also report useful findings on the impact of gender and cognitive ability and career background and thus shed some empirical light on an issue that is often obscured by assumptions and conjecture.
This is a thoughtfully designed study and we need more such studies to allow us to go beyond "They said" conjectures about the impacts of graduate education or management education in general.

I would be far more supportive of this position if there was any research that demonstrated even a simple correlation between MBA ?grades or marks? and employment success. We continue to hear that there is little connection between academia and practice. In addition, there are publication that infer that management education is so disconnected with the practice of management that the more we ?learn? the lower the performance of on line managers.
Imposing an arbitrary cut score on marks is highly suspect from any science of measurement perspective. I think that it?s true that selling the ?consumer? model to students in pursuit of hard $$$ in exchange for degrees is less than ?ethical?. So long as potential users of the educational system believe that academic A?s guarantee better employees, maybe we?re stuck in an endless loop.
With regard
Henry
