I would probably customize a training plan based on what the new executive director already knows. If s/he has worked for a center in the past, s/he may not need history and philosophy but might need board and finance training. There is training for almost every item in the E.D.’s job description. You can search the website for a topic, or contact me and I will help you find what you are looking for. I like everything to be in the context of philosophy so I have included that.
The Rapid Course on history and philosophy is three parts and found at http://www.ilru.org/training/foundations-independent-living-series or if they don’t love that read and test format, the short films at http://www.ilru.org/il-history-and-philosophy-orientation-for-il-staff are great.
The financial management workshop (15 hours) at 
http://www.ilru.org/training/financial-management-workshop-for-cils-regulations-and-beyond is great for financial regulations. The topics are broken down so the person can watch what is the most useful, in any order.
For board recruitment, http://www.ilru.org/training/attract-and-retain-your-best-cil-board-members
There is also a monthly call for executive directors. Be sure to let me know so I can sign them up for that call.
How is that for starters? A new E.D. can request anything specific from me any time so make sure they have my name and number.
