Troy,
I would suggest you develop a "T" table with the descriptions of each type of board, one the left and the other on the right, then use this as a visual to communicate the differences between the two broad types. After illustrating the differences and explaining the values to senior management, you will need to specifically determine how the boards will be utilized in support of your school and programs. Be sure to solicit questions from your management team, which should provide substantial opportunity for you to elaborate and communicate your vision for the each board's contribution.
