In which plan is the appointed County Administrator supervised by the President of the Freeholder Board?

The correct answer is the Board President Plan. In this governance structure, the appointed County Administrator is directly supervised by the President of the Freeholder Board. This setup allows for a more centralized form of oversight, where the President holds the responsibility of managing the Administrator's performance and ensuring that the county’s operations align with the policies set forth by the Freeholder Board.

In this plan, the dynamics between the President and the Administrator create a framework that emphasizes accountability and responsiveness. This is distinctly different from other plans, where either the entire board or a separate executive figure may have oversight over the administrative functions, leading to varied governance styles and levels of direct supervision.

Other choices represent different governance models, such as the County Manager Plan or the County Executive Plan, where the executive’s role and the relationship with the legislative body are structured differently, often not involving the board president directly in the supervisory capacity over a county administrator.
