Suggested Timeline Leading to ABO Director Appointment

Stage One: The Constituent Organization’s Nomination

September – January

(16 - 20 months prior)

ABO central office notifies the Board of Directors, via the President/Executive Director, of the constituent organization that the ABO Director Selection process should commence. 

The ABO recommends that an ABO Director Selection Committee is appointed by the constituent organization.  The current ABO Director from the constituency may be included in the committee meeting(s) but only to act in an advisory capacity to the constituency.

February – November

(6 - 15 months prior)


ABO central office is notified of committee appointments and the chairperson for future communication.

Solicitation begins for ABO Director candidates from the constituent organization.  The entire membership of the constituency should be notified that all ABO certified members of the constituent organization are eligible.  A deadline for submission of the candidate names and their curriculum vitae is strongly recommended. The nominating committee should meet to discuss and schedule interviews for viable candidates.

By December 1

(5 months prior)

The committee chairperson is required to submit a list of three to five final nominees to the ABO President/CEO. The nominees should be informed and committed to the Director expectations and responsibilities. 

Stage Two: The American Board of Orthodontics’ Nomination

By December 15th

(5 months prior)

Each ABO Director nominee will be asked to submit a one (1) page biography with Curriculum Vitae highlights as well as a personal statement to include areas of interest, qualifications and the nominee’s potential contribution to the Board.  If the nominee has a non-time limited certificate and the nominee has not already voluntarily recertified, the nominee must recertify prior to ABO Director interviews.  The ABO staff will make arrangements with the constituent nominees and the chairperson of the constituent nominating committee to participate in interviews with the ABO Directors.  All the curriculum vitae and personal statements will be forwarded to the ABO Directors.

February - March

(2-3 months prior)

ABO Directors will interview each nominee.  The chairperson of the constituent nominating committee will be invited to attend the ABO interviews. Once interviews are complete, a super majority vote will determine the chosen ABO Director Nominee.  The ABO President will notify the AAO Trustees of the selected nominee and provide the curriculum vitae following the ABO Directors’ decision.

Stage Three: The AAO Board of Trustees and House of Delegates Nomination


(2 months prior)

The AAO Trustees will consider the ABO’s nominee and pass the nominee to the House of Delegates for their consideration (as per Article XIX - American Board of Orthodontics of the Bylaws of the American Association of Orthodontists).  If the Trustees reject the nominee, the ABO Directors will submit a new nominee for approval.

April/May Annual Meeting of the AAO

(1 month prior)

At the meeting of the House of Delegates of the AAO, the ABO’s nominee that has been approved by the AAO Trustees will be presented to the body and voted upon.  If the House of Delegates rejects the nominee, the ABO Directors will submit a new nominee for approval. If the House of Delegates favorably supports the ABO’s nominee from the constituent organization, that nominee is duly elected as a Director from the constituent organization and will assume the duties of the Director at the end of the AAO annual meeting.
