Are the new Power, Privilege & Oppression CEUs required by RID Professional Studies?

Yes!   The are only 2 categories of CEU types under RID:  Professionals Studies (PS) and General Studies (GS).  
Under PS, there are extra labels called Specialization Categories, required for people who have specialization certificates, like an SC:L, for example.  It can be helpful to think of these Specialization Categories a sub-labels under Professional Studies.  
PPO is a Specialization category under the Professional Studies umbrella.  Ethics and Legal are other Specialization labels.   (RID does not require specific Ethics credits to be earned in a cycle, but some state licensing/certifications do.)
Everyone who completes PPO labeled projects earn Professional Studies CEUs. 
In summary: All PPO Specialization labels on our site earn Professional Studies credit.
