Need information on good BPA certifications/centers/universities, that are available in and around philadelphia.

I already have a Masters's degree and have worked as a Business Process Analyst, I Have the experience but now need a concrete certification.

I browsed and found out there are many universities offering online certifications for BPA's, but which university is good, what should i look for when opting for a certification course, how much should such a certification cost.

Thank you

Priya
