Geologist Licensing

Requirements for Geologist Licensing - Frequently Asked Questions


Q1. Where can I find an application for licensure as a geologist?     Back

Licensure is managed by the Board of Licensure for Geologists and Soil Scientists under the Maine Office of Professional and Occupational Registration. Application materials can be found at their website.


Q2. Who needs to be licensed as a geologist?     Back

Individuals conducting geological investigations in Maine for the public must be licensed. For the purposes of licensure, the terms "geology" and "practice of geology" are defined by statute (Title 32, Chapter 73).


Q3. What are the requirements for licensure?     Back

A combination of academic and professional experience is required for licensure.

Education: Generally, a candidate must be a graduate of an accredited college or university with a major in geological sciences, or have completed 30 credits in geological sciences at an accredited college or university.

Experience: Generally a candidate must have acquired 7 years of experience in responsible charge of geological work, toward which an undergraduate degree with 30 credit hours or more in geological science courses shall count as 2 years of training and each year of graduate study in the geological sciences shall count as 1/2 year of training, up to a maximum of 2 years of credit.


Q4. Is an examination required for licensure?     Back

Yes, the Board of Licensure for Geologists and Soil Scientists uses the National Association of State Boards of Geology (ASBOG) national examination together with a local knowledge examination to license geologists. The examination is offered twice a year in March and September.


Q5. Is there a study guide for the national examination?     Back

There is no specific study guide for the national exam. For information on the national exam, please visit: National Association of State Boards of Geology There may be private firms that offer study courses toward completing the national exam.


Q6. Is there a study guide for the local knowledge examination?     Back

While there is no specific study guide for this examination, the Maine Geological Survey recommends review of the following materials:
