ASBOG Practice of Geology Exam

The applied professional judgment examination, and the final examination step before Professional Geologist licensure.

Quick answer

The applied professional judgment examination, and the final examination step before Professional Geologist licensure. Issued by National Association of State Boards of Geology. Intended for geologists who have completed their state qualifying experience requirement.

Our position

This exam tests whether you can act like a professional, not whether you memorized a textbook. Candidates who have done varied field and reporting work pass comfortably. Candidates who have done one narrow task for five years struggle, and that is a signal worth reading about your job, not just about the exam.

How it differs from the Fundamentals exam

The Fundamentals exam asks whether you learned geology. The Practice exam asks whether you can apply it responsibly: scoping an investigation, choosing methods, interpreting data with appropriate caution, understanding professional and ethical obligations, and communicating findings to people who will act on them.

Preparation is therefore less about textbook review and more about reflecting on your own project experience. Candidates who have worked across site investigation, reporting, and regulatory interaction find the examination reflects work they have already done.

What this means for you

If your work has been narrow, deliberately broaden it before you sit the exam. Ask for exposure to scoping, client communication, and report defense rather than only field data collection.

Verify your experience documentation with your board well before you register, since experience verification is the step that most often delays candidates.

Fees, eligibility rules, and examination windows change. Confirm every figure on this page with the issuer before you plan around it.

Frequently asked questions

How much experience do I need first?

Commonly around five years of qualifying supervised experience, but the exact requirement and its definition are set by each state board.

Can I take both exams at once?

Some boards permit taking both in the same cycle for candidates who already meet the experience requirement. Most candidates take the Fundamentals exam years earlier.
