Geology

The Ph.D. in geology is a research-intensive doctoral program combining advanced geological study with independent, original research. Students develop specialized expertise through graduate coursework and faculty-mentored research while building the analytical, field and scientific communication skills needed to contribute new knowledge to the geological sciences.

University of Idaho is committed to making graduate education accessible and helping students navigate the cost of earning an advanced degree. In addition to financial aid and scholarship opportunities, many graduate students receive funding through assistantships, research opportunities and other forms of academic support.

Here are a few key resources to help you understand graduate tuition, funding opportunities and available financial support:

• Submit your FAFSA: Completing the Free Application for Federal Student Aid (FAFSA) is the first step to accessing federal, state and institutional financial aid.
• Estimate your cost of attendance: Use U of I’s Cost Calculator to estimate tuition and other expenses associated with earning your degree.
• View a breakdown of tuition and fees: Visit the Student Accounts page to explore current tuition rates, fees and detailed cost information based on your program, residency status and enrollment level.
• Explore scholarships and graduate funding opportunities: Graduate students may qualify for scholarships, fellowships and other funding opportunities based on academic achievement, area of study and professional experience.  
• Learn about assistantships: Many graduate programs offer Research Assistantships (RAs), Teaching Assistantships (TAs) or Graduate Assistantships (GAs), which may provide tuition support, stipends and valuable professional experience. Assistantship availability and funding levels vary by program and department.  
• Connect with your program: Some graduate funding opportunities are coordinated directly through academic departments or faculty research projects. Prospective students are encouraged to review department funding information and speak with program representatives about available opportunities.  

If you have questions about financial aid, scholarships or graduate funding, U of I’s experienced financial aid counselors and graduate program staff can help you explore options and make informed financial decisions throughout the admissions process.

Application and admission process:

Applications are submitted online and are specific to the program and term selected. Applicants seeking admission to multiple programs must submit a separate application for each program.

Before submitting an application, applicants must provide personal and academic information from all post-secondary institutions attended, recommender information, required program-specific materials and their intended program and start term.

Applicants seeking a Ph.D. are encouraged to identify and contact a potential faculty advisor or major professor during the application process. Early identification of an advisor can help ensure that a faculty member in the applicant’s area of interest has capacity to supervise the student and appropriate research opportunities are available. Applicants should consult the College of Science website to identify faculty whose research aligns with their academic and research interests. 

Applications are reviewed for admission by the academic program. Only complete applications, including required letters of recommendation and payment of the application fee, will be forwarded for evaluation and admission decision. Applicants are strongly encouraged to complete their applications early to allow sufficient time for a thorough review.

International students seeking F-1 or J-1 visas must provide financial documentation demonstrating their ability to cover the cost of attendance. This documentation is required only after admission.
