Frequently Asked Questions

List of 7 items.

  • What firm is supporting the search process?

    The Board of Trustees has engaged Resource Group 175 (RG175) to partner with The Rivers School on our head of school search. RG175 Senior Consultant Tom Olverson and Managing Partner John Farber will facilitate and support the process of identifying the very best individual to lead Rivers through its next chapter. Tom and John bring a thorough knowledge of the independent school landscape in the Boston area, and we were particularly drawn to the more transparent process they use. We are also confident that Tom Olverson, having served as Head of School at Rivers from 1997-2014, will bring a unique and invaluable depth of perspective to the search.
  • What is the timeline for the search?

    The current plan is to be able to identify a candidate and make a recommendation to the Board of Trustees by October 2022. The new head will assume responsibility on July 1, 2023.
  • What is the role of the Board of Trustees in the search?

    The Board is ultimately responsible for selecting the head of school. The task of conducting the search will be undertaken by a board-designated Search Committee, assisted by advisory committees comprising faculty, alumni, and parents.
  • How were Search Committee members selected?

    Search Committee members have a deep commitment to Rivers and a firm grasp of the school’s history, mission, and approach. They represent a diversity of viewpoints and experience, but they all share a love of the school and a strong desire to help steer the school through this exciting transition.
  • What is the role of the Search Committee?

    Initially, the Search Committee is charged with defining the qualities required of the next head of school. As the process moves forward, they will review candidate files, interview the most viable candidates, speak with multiple references, and make a final recommendation to the Board of Trustees.
  • How will the Search Committee keep the community updated?

    While much of the search process must be kept confidential, we are also committed to transparency and candor. The community will be kept updated through this website, as well as through periodic direct communications from the Board and the Search Committee.
  • How can I help during the search?

    Broad community input will be critical to facilitating a successful leadership transition. All community members will have an opportunity to complete an online survey, and we will be providing forums for faculty, staff, and parents to meet with finalist candidates later in the process. Here are some other ways in which community members can help:
    • Please make sure our search consultants are aware of any individuals whom you would recommend as potentially strong candidates. Please note that in addition to providing the search committee with valuable perspective, the survey also allows for you to suggest potential candidates.
    • Please bring any rumors or speculation directly to the Search Committee to minimize the spreading of any inaccurate information.  
    • Finally, please read carefully any communications from the Search Committee.
