What is Board Certification and why is it important?

Over the past decade, there has been considerable discussion among the DPA leadership concerning whether or not the DPA, like many of the other certification programs, should require some sort of continuing education or professional development to help raise the standard of certification.

A special committee was formed to develop a Board Certified membership level. This is a voluntary category of membership that recognizes those members that maintain their continuing education.

The requirements for certification (Article III. Section 6) at the Board Certified level are:

  1. Active member of the Division for a period of five years;
  2. Completion of a minimum of 20 professional development hours per year per the guidelines set forth by the Division’s Board of Certification;
  3. Annual affirmation to the Board of Certification of adherence to the AAPG's Code of Ethics.

Professional Development Hours (PDH) shall be considered that period of time during which the member is engaged in activities directly related to the transference of skills or knowledge as set forth in these guidelines above.

It is the vision of the DPA to develop reciprocity agreements with all states which have registration.

Irrespective of whether or not we successfully negotiate reciprocity arrangements with any state, the title Board Certified Petroleum Geologist will increase the prestige of those who have taken the time to earn it.

Requirements for Certification

Active member of AAPG.


Graduate of recognized institution with a degree in Geology.


A minimum of 8 years experience... (7 years with a Master's Degree | 6 years with a Ph.D.)

Professional Standards

Demonstrates a sustained record of the highest professional and ethical standards.

In the extenuating circumstance that such Sponsors are not available to the applicant, the applicant may be sponsored by noncertified AAPG active members having training and experience equivalent to the requirements for certification at the Certified Member level. Sponsors' endorsement shall be furnished in writing.

Board Approval

Approved by the Board of Certification of the Division of Professional Affairs.
