For the second renewal, you must complete an application and a series of reflective essays. Start the CDEI Second Renewal here: https://www.idecc.org/cdei-second-renewal/
As part of the second renewal application, you will have an opportunity to update your contact information. Then, you'll be presented with several essay questions asking you to relate your understanding of key concepts from the CDEI courses, and how you have applied them as an instructor. You can complete the questions in any order and stop and come back at any time. Once you complete the essay questions and pay the renewal fee, your CDEI designation will be renewed for another three years.
