California Professional

Geologist Licensure

Obtaining a Professional Geologist (PG) License

Becoming a PG is a significant professional accomplishment and there are many rewards:

  • You can make a significantly higher salary.

  • You can work on, and have greater responsibility for, a greater variety of projects.

  • It is easier to change jobs or start your own business in geologic consulting.


  • Appropriate education: sufficient units in geology overall and within specified topics.

  • Sufficient work experience under other licensed professional geologists.

    • Note that work experience does not start to accumulate until your educational background meets the educational conditions. This means: Study geology now! You'll enjoy it, anyway.

  • Passing the California state Professional Geologist Exam

The Geology Concentration is designed to satisfy

the educational requirements for obtaining a PG license

Note: Reading through the legalese of these documents can be kind of a slog.
