Department of Geosciences Graduate Degree Handbook

Congratulations on your acceptance to the Department of Geosciences graduate program. This page is our graduate student handbook and information for MS and PhD Geosciences graduate students

⏳Pre-Arrival

Once you receive your official Colorado State University Notice of Graduate Admission, make sure to complete the following steps. A full explanation of each step can be found on the Graduate School Website.   

🎓 Academic & Course Planning 

  • Meet virtually with your advisor to plan your first semester schedule. 
  • Fall registration opens in April. Register via RAMweb and consult Registrar’s course registration guide. 
  • A few notes on course registration:
    • There is no set curriculum — your advisor will guide your course selection based on your research area.  
    • We recommend enrolling in GEOL 601: Professional Development for Geoscientists, a 1-credit course ideal for all new M.S. students.
      • This course is specifically designed to make the transition to graduate school at CSU go smoothly. It covers topics like thesis proposal writing and research ethics, and fulfills the federally required ethics training for students supported by grants.
  • How to register for more than one credit in a variable credit course (698, 699, 798, 799):
        • Add the course to your schedule (just 1 credit) and click “Submit”. 
        • Go to the tab on the top left titled “Schedule and Options”. 
        • There, you can modify the number of credits. 
        • Hit the “submit” button again to save any modifications.

Review timeline, credit and degree requirements for your degree to prepare with an in-person meeting with your advisor when you arrive in Fort Collins. 

🏠 Arrival in Fort Collins 

Welcome to Fort Collins! Your first weeks will be busy, so use this list to get settled and organized: 

  • Meet with your advisor in person. 
  • Get your CSU RamCard (student ID) 
  • Request keys (if needed) by visiting the GEO front office 
  • Attend Graduate School orientation and other welcome activities. 
  • Meet GEO faculty and fellow grad students. 
  • Come to GSO and other welcome events 
  • If you are working as a teaching assistant, meet with the faculty member teaching your course to gather a teaching plan and schedule and attend GTA training through TILT (only for TAs) 

Parking and Transportation

There are many transportation and parking options for Colorado State University. Please go CSU Transportation to review your options, or for parking permits visit CSU Parking.

🧩 Additional recommended items 

🏷️Residency

While Colorado residency is not required for graduate study, it significantly affects your tuition costs. During your first year, most Graduate Teaching Assistants (GTAs) and many Graduate Research Assistants (GRAs) have their tuition covered at the resident rate. However, after the first year, non-resident students will be responsible for paying the difference between resident and non-resident tuition, which is substantial and not covered by the department.

If you are a domestic student (U.S. citizen or permanent resident but not a Colorado resident), it is strongly recommended that you begin the residency process during your first year. Colorado has strict requirements for establishing residency, and the process must begin at least one year in advance of when you plan to claim residency status. In most cases, this means starting the process early in the spring semester of your first year.

📌 What You Need to Know:

Note: International students receiving assistantships are exempt from the residency process unless they already hold a green card.

What do I need to do to present clear and convincing evidence that I have been a resident for at least a year prior to the fall of my second year? You must: 

  • Be a qualified person 23 years or older at the start of your second year (or legally emancipated)
  • Establish a fixed and permanent home in Colorado:
    • Lease agreement/rent receipts
    • Colorado address in Ramweb (from August 24, 2025 – August 24, 2026) 
  • File Colorado state income taxes as resident in Colorado 
  • Obtain two of the following:

The first milestone in your study is the completion of the GS6: Program of Study. This document outlines your planned coursework and assigns members to your graduate committee. It is required by the Graduate School and is typically submitted by the end of your second semester. Failure to submit it on time may result in a registration hold. 

📅 When to Complete It: 

Start planning your GS6 early in your second semester. Schedule a meeting with your advisor to map out your coursework and discuss committee formation.

👥Graduate Committee

The function of the committee is to guide you in the development of your curriculum, research and thesis or dissertation. It is their responsibility to judge whether your work throughout this process warrants the conferral of a graduate degree. Your adviser will help you identify your committee members.

Select members who:

  • Understand your content area.
  • Have research interests compatible with yours.
  • Complement each other in the knowledge you want to attain through your program of study.

If for any reason you wish to change your committee member, do so by submitting a GS9A- Petition for Committee Member Changes.

Graduate Coursework

Your GS6 must list all courses you have completed and those you plan to complete during your degree. We recommend making an outline of your coursework before starting the GS6.

Note: You cannot edit the GS6 once submitted. If your courses change later, you’ll update them using the GS25: Application for Graduation during your final semester. 

The Department of Geosciences and its faculty support both Graduate Teaching Assistants (GTAs) as well as Graduate Research Assistants (GRAs). All Graduate Assistants must meet the Graduate Assistantship – Terms and Conditions of Appointment as detailed in the Graduate and Professional Bulletin. They must also be registered for at least one graduate degree credit. (Continuous Registration (CR) does not apply).

  • GTAs assist faculty in the teaching of undergraduate courses, primarily in the supervision/teaching of our lab components. Teaching assistants may be responsible for presenting lab material, supervising lab activities, grading, giving exams, and assisting with field trips.
  • GRAs assist their graduate advisor with their research activities. This may include field work, sample gathering and processing, data analysis, and authorship.

Assistantship resources information.

**Please Note: your first paycheck may not come until the end of September. Please plan accordingly.**

🎓 Graduation Checklist

To graduate, you must submit the GS25: Application for Graduation by the deadline for the semester you plan to finish. View current deadlines on the Grad School deadline dates website. If your timeline extends to the next semester, you can re-submit the GS25 form with the new term date. Summer graduates who want to walk and have their name listed in the commencement announcement for spring, must submit the GS25 early in spring semester- refer to the spring deadlines for that specific date.

🎉 Commencement Options 

For information on commencement, please see the CSU Commencement website, and the Grad School Commencement website.

Masters Research

During your first semester at CSU, you should start groundwork for your thesis (literature review, proposal) and begin identifying potential graduate committee members. By the beginning of your third semester you should have started your research and be at a point where you can analyze the data. At this point, you should meet with your advisor to plan your remaining research and thesis.  

Masters Thesis

The thesis will be an in-depth paper written using your own or shared research. An outline and perhaps a first draft of your thesis should be completed during the third semester. Utilize your advisor and committee for help and guidance in the analysis of your data, structure of the thesis, and writing style. Discuss the structure and content of your thesis with your advisor early, and early and ask for examples of previous students to guide your work. You can review previous student theses on Mountain Scholar to get an idea of what a thesis looks like. 

Understanding Research vs. Thesis Credits

You will register for both research credits (GEOL 698) and thesis credits (GEOL 699) as you progress: 

GEOL 698: Research 

  • Typically taken earlier in your program.
  • Used while you are actively conducting research, collecting data, or doing background work. 
  • These credits do not count toward the thesis credit requirement but may count toward total degree credits. 

GEOL 699: Thesis 

  • Taken when you are actively writing your thesis. 
  • These credits fulfill the Graduate School’s Plan A thesis requirement (a minimum of 6 credits). 
  • Should be taken closer to your defense semester 

Planning Your Defense & Graduation

  • Decide your intended graduation semester and consult Graduate School deadlines.
  • Submit the GS25: Application for Graduation (due early February for spring, early September for fall). 

Your thesis will be examined in an oral presentation before your advisor, committee members, and other colleagues. 

Before scheduling your defense:

  • Review your committee in RamWeb.
    • Make sure all members are listed correctly and hold active CSU faculty appointments.
    • If you need to make changes, submit a GS9A Committee Change Form
    • External members must have current affiliate status — check with the department office to make sure affiliate status is current.
  • Verify your GS25-Application for Graduation
    • This form needs to reflect the correct semester you are graduating. Confirm the graduation semester listed is accurate. If you’re graduating later than expected, update your GS25 accordingly.
  • Choose a defense date
    • Coordinate with your committee.
    • Check the Grad School deadlines, some of these come early in the semester.
    • Submit aGS25-Application for Graduation. These are due in early February for spring graduation or early September for fall graduation. The GS25 is a plan to graduate, however, if circumstances happen in which you need to delay, you can revise this plan as needed.
    • Work with your graduate coordinator to schedule a room and advertise the event. 
  • Check the deadline dates for forms GS24 and GS30.
    • Will you have enough time to complete your Thesis and upload it to ProQuest? The deadline dates are:
      • Spring graduation: mid-March
      • Fall graduation: mid-October

If not, you may defend in one semester and graduate in the next. In that case:

    • Update your GS25 to reflect the new graduation term
    • Register for Continuous Registration (CR) during the term you are officially graduating

To assist you and your advisor in planning your courses, the department has developed the graphic below and a spreadsheet to track plan and track your progress.

Graphic of PhD Coursework without previous MS degree

Getting Started

Begin developing your research focus as early as your second or third semester. Discuss potential topics with your advisor well before reaching candidacy—ideally as soon as you begin the program.

Preliminary Examination

You will take a preliminary comprehensive or general examination once you have completed the majority of your doctoral coursework, typically in the 3rd year of your doctoral program.

Format: Varies by advisor; may include a written paper and oral defense. 

Purpose:

  • Assess readiness for dissertation proposal and final dissertation work. 
  • Demonstrate ability to: 
    • Integrate and synthesize knowledge from coursework and academic experiences. 
    • Define and demonstrate knowledge of theoretical constructs, extant research, and research methods relevant to the domain of inquiry in which you will conduct your dissertation research 
    • Demonstrate depth and breadth of knowledge in your area of study 

Process:

  • Work closely with your advisor to determine readiness and prepare. 
  • Committee reviews your written and oral exam. 
  • Passing the preliminary exam advances you to doctoral candidate status. 

Dissertation Proposal

Once you have reached candidate status, it is time to begin your dissertation proposal. You should think about the topic of your research and discuss it with your adviser as early in your program as possible.

Ideally, you will have explored research subject ideas when you were first admitted to the doctoral program. It is important that you thoroughly discuss potential research topics with your adviser.

Once you have completed your dissertation proposal and your adviser has confirmed it is ready for committee review, you will need to schedule a dissertation proposal defense with your graduate committee. To allow committee members adequate time to read and evaluate your proposal, you must provide each committee member with a copy of your proposal no later than two weeks prior to the meeting.

The dissertation is a formal written document in which you present original research and analysis of your data. Once you, with the help of your adviser, determine your dissertation is complete and ready to be presented, your dissertation oral defense can be scheduled. The defense is designed to show your ability to fully and coherently discuss the meaning of your findings.

Before scheduling your defense:

  1. Review your committee in RamWeb.Is there anyone on the committee that should be added or deleted? Do they all have a current faculty assignment? External members need to be a current affiliate with the department, check with the department office to make sure their affiliate status is current.
  2. Is your GS25-Application for Graduation up-to-date?This form needs to reflect the correct semester you are graduating.
  3. Select a date for your oral defense with your committee. Work with your  graduate coordinator to schedule a room and advertise the event.
  4. Dissertation drafts are sent to your committee. These must be completed ~6 weeks prior to your defense to allow time for revisions and 2 weeks lead time to your committee for their review.
  5. Check the deadlines dates for forms GS24 and GS30. Will you have enough time to complete your Thesis and upload it to ProQuest? The deadline dates are mid-March for spring graduation and mid-October for fall graduation. If these date won’t give you enough time, you can complete all of the work in one semester, but officially graduate in the next semester. To do this, you will need to change your GS25 graduation semester, and you will need to register for CR for the semester you are officially graduating.

Immediately following the defense:

  1. Submit a GS24-Report of Final Examination.The form, signed by your entire committee, must arrive to the graduate school within two days of the completion of our defense.
  2. Celebrate, because that was hard.

After your oral defense is completed:

  1. Make any final edits to your dissertation.
  2. Dissertations must follow specific formatting guidelines. The Graduate School offers guides, sample pages, and publishing resources on its Electronic Thesis and Dissertation (ETD) Resources website. The Graduate School will review your thesis for formatting; once all formatting is correct your thesis will be cleared for publishing
  3. Submit your GS30-Thesis and Dissertation Submission form
  4. Uploading your thesis to ProQuest/UMI though the CSU Libraries ETD Submission Website
  5. Competing the Survey of Earned Doctorates Certificate

Lastly:

  1. Competing the Survey of Earned Doctorates Certificate
  2. Return any keys you have to the front office
  3. If you have rock samples, arrange for long term storage or disposal with your advisor. Please do not leave important samples at your desk, they will be disposed of.
  4. Clean out your desk
  5. Please leave a forwarding email address with the Grad Coordinator.
