Frequently Asked Questions

What are the eligibility requirements to sit for the PG Fundamentals of Geology Exam?

Eligibility is determined by individual state licensing boards, but common requirements include: a minimum of a Bachelor's degree in geology or a closely related geoscience from an accredited institution; a specific number of credit hours in geological science courses; and a period of supervised professional geological work experience (typically 3-5 years). Some states allow you to sit for the exam prior to completing all experience requirements. You must apply directly through your state's board for approval to test.

How is the exam structured and what is the format?

The ASBOG(R) Fundamentals of Geology (FG) exam is a 4-hour, closed-book, multiple-choice test consisting of approximately 120-140 questions. The questions are designed to assess knowledge and application across the core domains outlined in the official exam blueprint. The exam is typically administered in a pencil-and-paper format at designated testing centers twice per year, in the spring and fall.

What is the difference between the 'Fundamentals of Geology (FG)' and 'Practice of Geology (PG)' exams?

The FG exam tests broad, academic knowledge and fundamental principles of geological science. It is often the first exam taken. The Practice of Geology (PG) exam focuses on the application of geology in professional practice, including ethics, regulations, business practices, and advanced problem-solving related to case studies. Most states require candidates to pass both the FG and PG exams, along with meeting experience requirements, to obtain the full Professional Geologist license.

What is the passing score, and how is the exam graded?

The passing score is established by ASBOG(R) and the state boards using psychometric analysis and can vary slightly between exam administrations. Scores are reported on a scaled basis. Your state board will notify you of your pass/fail status. Raw scores or specific numerical cut-offs are not typically disclosed to candidates.

How should I prepare for the exam, and what are the best study resources?

Effective preparation involves a multi-faceted approach: 1) Obtain and thoroughly review the official ASBOG(R) Candidate Handbook and Exam Blueprint, which details the exact content areas and their weightings. 2) Use comprehensive review manuals and textbooks covering all blueprint topics. 3) Form or join a study group with other candidates. 4) Complete as many practice questions and simulated exams as possible to familiarize yourself with the question style and pacing. 5) Focus on integrating knowledge across topics, as exam questions often require synthesis of concepts from different geological disciplines.
