What % of project managers in a PMO should be Certified?

I agree with the above statements. The U.S. federal government has started mandating certification, which I think is a good thing. I think 100% is difficult, and it's always good to have certified PMPs mentoring junior PMs who are working towards their certifications.

There is no defacto percentage, but I'd say a minimum of 25% is not unreasonable.
I like Eric's take on it. Showcase the value to the customer from professional designations held within the organization. Having employees with respected certifications in the industry is certainly a distinguishing trait for sales and advertising, but having the ability to showcase value through success stories provides an additional edge. Be careful though, while a designation gives a nice cover, at the end of the day, its the content that is important.

Percentages in this context mean very little. Assess if the PMO needs certified people, and if the answers is yes. and you employ some, divide it by the total PMO staff and you will have a percentage after the fact, rather than before the fact.
