Geologist Licensure by Reciprocity

When to Apply

The two methods by which Geologist applicants can apply for licensure are reciprocity and examination.

Apply by reciprocity only if you meet all of these criteria:

  • You hold a current geologist license in good standing in your selected reciprocity state, AND
  • You have at least two years licensed professional geologic work experience in your selected reciprocity state, AND
  • You have passed the ASBOG examinations unless your license in your selected reciprocity state was issued before June 17, 1998. Note: If you were licensed in your reciprocity state after June 17, 1998 but have never passed the ASBOG examinations, you cannot apply by reciprocity.

If you do not meet all of these criteria, you must apply by examination.

Selecting Your Reciprocity State

When applying for Geologist licensure by reciprocity, you must choose ONE reciprocity state. The term reciprocity state means the jurisdiction (which includes state, U.S. territory, or District of Columbia) where you:

  • hold a current Geologist license, AND
  • acquired two years of licensed professional geologic work experience.

Even if more than one jurisdiction where you hold a current license meets the definition of reciprocity state, you must select only one. In selecting your reciprocity state, remember that the entire two years of required licensed professional geologic work experience had to take place in the reciprocity state. Experience on projects that took place in other jurisdictions does not count even if you were employed by a firm in your reciprocity state at the time.

  • click “acknowledge” . This means you will either have to mail the documents yourself or request the “third-party” mail the document(s) directly to the Board office.
    • Examples of “third-party forms” are transcripts from schools, employment verifications from a supervisor, and license verifications from another state.
  • Forms requiring a supervisor signature, seal, or notary may have to be MAILED to the Board office directly UNLESS the document specifically indicates to UPLOAD the document.
