A. Both of these certifications evaluate an event professional's knowledge of certain areas of the event industry, but they differ in what experience they measure.
The CPM exam, administered by the Convention Industry Council, measures a candidate's specific knowledge and experience in meeting and conference planning, evaluating a variety of skill areas from strategic meeting management to the nuts and bolts of learning objectives and vendor management. The exam digs deep into specifics directly related to conventions and meetings, and so the CMP designation certifies a professional's experience in and knowledge of these areas.
While the CSEP exam, administered by the International Special Events Society, overlaps with the CMP exam a bit in areas such as budget management and risk assessment, it focuses more specifically on evaluating skills related to the design and execution of special events. Rather than focusing on the many project areas of a multi-day conference or meeting, the CSEP exam measures more specific skills related to planning a special event, such as a wedding, gala, or corporate evening event (to name only a few). This designation lets others know that you have in-depth knowledge of special events and are comfortable executing them from start to finish.
