What is the CPM Certification?

The Certified Purchasing Manager (CPM) credential, offered by the Institute for Supply Management (ISM), was once the choice for purchasing managers. Recently ISM has been transitioning to the Certified Professional in Supply Management (CPSM) certification to reflect the additional duties that purchasing managers are responsible for. The CPM exam is now reserved for recertification only, so unless you currently hold a CPM certification you must become CPSM certified.
