Course Director (CD) Renewal

What is a renewing CD?  Renewing CDs are individuals who have maintained their status as CAOHC-approved CDs for the past five years and have met all application requirements.

What is necessary for CD renewal? Applicants must submit an application with all applicable documentation and fees, meet renewal criteria, re-sign the non-disclosure agreement, and achieve a passing score on the CD examination.

Professional Requirements for Renewal

  1. CDs seeking renewal will document the professional and credential requirements described in the "How to Become Certified as a CD"  section.

Course Directors who are COHC's

  1. In order to preserve the integrity of the standardized written examination, approved Course Directors who wish to maintain their COHC credential will submit a COHC application to CAOHC (front section of the standardized written examination answer sheet) along with recertification fees, but are not required to take the recertification workshop or standardized examination.
  2. Course Directors are not permitted to view the standardized written examination (certification or re-certification).

Training and/or Activity Renewal Requirements and Options

  1. Before the expiration of current CD status, submit the Course Director Renewal application and current renewal fee.
  2. Fulfill the criteria outlined in either OPTION 1 or OPTION 2 and successfully pass the CD examination, during the designated times, before the end of the five-year credential term:


  1. Complete the eight-hour CAOHC CD training workshop.
  2. Complete the on-line examination with a passing score of 80% or higher.
