The Center for Plain Language, located in Richmond, Virginia, USA, is a non-profit organization which aims to help government agencies and businesses write clearly in English and Spanish.
The Center supports plain writing legislation and evaluates how well federal agencies comply with requirements.
It also celebrates good writing with “ClearMark” awards, and publicizes bad writing with “WonderMark” awards. You may enjoy the WonderMark Hall of Shame here. 🙂
A 5-step checklist for better writing is also available.
