Not necessarily. The number of PDUs for each credential is independent of other PMI credentials and therefore, the PDU values for the PMI-SP and PMI-RMP credentials do not add up to equal the value of PDUs for PMP or PgMP credentials. The number of PDUs applicable to a PMI-SP or PMI-RMP credential is based on the amount of material relevant to those specialty areas, while the number of PDUs applicable to the PMP/PgMP credentials is relevant to general project management. Project management is made up of many knowledge areas of which risk management and scheduling management are only two. It is possible that a particular activity may not apply to project risk or project scheduling at all, but if the materials do apply to these areas, only the portion that is pertinent to these areas can be counted towards those credentials.
