A frequently asked question in certification circles is: Who may not author or contribute to preparatory courses and exam study materials, or lead study groups related to the certification?
The only individuals prevented from contributing in this way are those who have been directly involved with certification test question writing – which sometimes includes certification board (CB) members. Item writers and CB members should sign agreements with the CB stating that they will not be involved in any activities which serve or could be interpreted to serve as preparatory for the certification exam for an established period of time extending beyond their related volunteer term (often 2-3 years).
An important distinction for CB members communicating with candidates is that they are free to talk about the process of certification and the content in general ways, but they should not be specifically training/preparing individuals to be successful on the certification exam. For example, they can certainly present at conferences and teach college courses; however, they should not lead courses that are promoted as preparatory for the certification exams.
