A financial institution I know of started an advisory board approximately a year ago. They had all the same expectations as a board member but did not have a vote. They were to contribute at meetings, and the goal was to have them as a pool for future board positions. Recruitment could be from some of the organizations or unions that will benefit from the education provided. I had experience with a non-profit that had organizations donate / invest in / sponsor a student for the cost of the program since the person may end up filling a much need position in the organization. Recruitment can be for other reasons such as experience (i.e. financial / legal / fund raising, etc) I have only seen board members as liaisons, but I could see the ED being involved.
