Overview of ASBOG and its role
ASBOG, the national Association of State Boards of Geology, is a non-profit group that creates standardized exams for people who want to become licensed geologists. By using ASBOG's exam, state boards can fairly measure a candidate's skills and knowledge in the geologic sciences. In Oregon, passing both parts of the ASBOG exam—the Fundamentals of Geology (FG) and Practice of Geology (PG)—is required to register as a geologist. Passing the FG is required to register for the Geologist-in-Training.
ASBOG examsThe FG checks what you learn in a typical undergraduate geology program, while the PG focuses on skills gained through work experience. Both exams are closed-book and use multiple-choice questions with four answer options. The FG has 140 questions, and the PG has 110. ASBOG updates these exams every five years based on surveying licensed geologists across the country about the minimum skills and knowledge needed to practice independently. Survey participants rate how important different tasks are for public safety. ASBOG uses these results to keep the exams fair and relevant for candidates from all parts of the country.
How exam content is developed and maintained
ASBOG relies on a Council of Examiners, which includes volunteer geoscientists, academics, and professional test-makers, to develop and maintain the exams. These experts come from various geological fields and different states. After each test session, the Council reviews the exam and plans updates for the next one. Based on their input, a psychometrician sets the final passing scores and adds new questions to the item bank for future exams.
Application and registration steps in Oregon
ASBOG does not decide who is eligible to take the exam in Oregon. You must apply to the Board for approval first. For more details, check the
Qualify for Exams and
Exam Dates pages. Also, passing the exam does not automatically mean you are a Geologist-in-Training or a Registered Geologist. ASBOG does not directly register geologists. After passing, you must apply to the Board to get registered. To learn more, visit the
