Question: Is there a difference between the CBT version available for download and the play now version? 
Answer: The two versions are available for convenience for our Mission Partners. We understand that some connections may not give the ability to stream the training from the website, so it might be more convenient to let the training download first and then watch. The downloadable version is also something Mission Partners can refer to at a later time. The play now version also has closed captioning enabled for accessibility if it would be more convenient to read the text instead of listening to the voice over.

Question: How are topics picked to be developed into CBTs?
Answer: The topics are picked from a variety of sources. Surveys to the Connection Approval, DSAWG, and PPSM analysts helped the training team determine which questions they received most from mission partners, and in-depth metrics analysis on the top connection approval package rejection reasons continues to contribute. Now that the program is growing, interaction from Mission Partners via email and during the Q&A sessions add to training topics. This program is designed to bring information to Mission Partners that is useful and needed, so the syllabus will always remain flexible based on the needs of Mission Partners.
