The Internship – Put Your Professional Science Master’s to Use Right Away
How the Ecosystem Science and Sustainability Graduate Internship Works
In lieu of a thesis, students working toward their Professional Science Master’s in Ecosystem Science and Sustainability complete a 400-hr, four credit professional internship, putting their skills to work and getting on the job experience.
The internship placement may be with an academic, governmental, business, or nongovernmental agency.
Students usually complete this internship during the last summer of their studies, working 40 hours per week for 10 weeks. Many students are hired by their internship partner.
Graduate Internship Placement
The PSM- ESS faculty advisor and ESS internship coordinator mentors and coaches each student throughout the internship placement process. Students learn how to:
- Identify and apply for positions
- Network with prospective host organizations
- Develop a professional resume
- Develop a professional LinkedIn profile
The student must apply for the internship. We are consistently growing our networking opportunities and faculty advisors will help you find the right internship fit.

More information on Diff Tuition:
https://financialaid.colostate.edu/media/sites/38/2023/04/Graduate_Differential_Tuition.pdf
Are scholarships, grants, or financial aid available for PSM students?
The PSM is not a traditional research degree program. There is no tuition remission and no dedicated Graduate Teaching or Research Assistantships set aside for PSM students. Therefore, PSM students should expect to pay for the program through loans and scholarships. Very rarely do teaching assistantships become available to PSM students.
There are scholarships available, both CSU and external, that are geared towards students in natural resources. To see awards specific to CSU, WCNR, and ESS, check out the ESS Scholarships & Fellowships site.
The ESS Department maintains resources on scholarships relevant to ESS students that is periodically updated. This includes scholarships and fellowships for students at all levels, even graduates, with applications through CSUSA and external sites. Keep in mind that some external scholarships will have due dates and award amounts that vary from year to year. Check their websites to be sure you know what the current year information is.
Here is a list of important Financial Aid related dates:
October 1st – CSUSA application (in RamWeb) and FAFSA open for the following academic year. Starting the application before the spring can alleviate some stress when it is closer to being due!
March 1st – CSUSA and priority FAFSA deadline. CSUSA applications – both general and for specific scholarships – must be completed by March 1. Submit your FAFSA by this day to be considered for as much aid as possible and if you are applying for CSUSA scholarships that have a need-based component.
Mid-March – Financial aid awards may begin appearing in RamWeb for you to review and accept. Some aid or scholarships may take longer to appear in RamWeb, this is the earliest you can expect to be notified of awards.
Download the ESS Scholarship guide to see scholarships through CSUSA that ESS and WSS or PSM students may be eligible for.
Can I work part-time while pursuing the PSM?
Some students do work part-time while earning their PSM.
We do not recommend working full-time while studying for the PSM. The program is meant to be an 18-month intensive and if you choose to pursue this timeline, your course load will be full. Most classes are only offered during the day, making full-time work a challenge.
Is there a thesis or comprehensive exam requirement for graduation?
There is no thesis required to complete this program – but there is a mandatory 400-hr (4 credit) internship that is often completed over the summer.
This internship is not guaranteed to be a paid internship, but many students do receive a paid internship.
Is there a dedicated career services center to assist with job placement and networking?
Students in this program have access to our department specific internship coordinator, in addition to WCNR Career services and CSU Career services.
Faculty advisors and the internship coordinator will provide internship placement options and support.
Will I have an advisor?
PSM students are assigned a faculty advisor in their specialty. In addition, students have an ESS Academic Success Coordinator who can help guide you.
Do you have to know how to code to enter the PSM in ESS?
Students do not need to know how to code to enter the PSM-ESS.
The core curriculum includes a robust, 5-credit introduction to data science course (ESS 523a) exploring tools and best practices for working with large environmental datasets, primarily using the programming language R. This course is intended to provide all PSM students with basic data science skills and understanding.
In addition to this course, the department hosts a Coding Club and provides suggestions for data science professional development courses through LinkedIn Learning to help students gain skills and confidence.
Will I get field work through this program?
A 400-hr, 4-credit professional internship is a required component of the PSM. Some internships involve outdoor field work – such as taking field samples or measurements – to support various types of research. However, PSM internships usually involve skill-building and application geared more toward data analysis and assessment.
What does the internship entail?
The internship placement may be with an academic, governmental, business, or non-governmental agency. It can be completed during the academic year or during summer.
Through the internship, students:
- Apply their knowledge and skills
- Address real-world environmental and ecosystem challenges
- Develop additional professional expertise
- Grow their professional network
During the internship placement, students enroll in ESS 587 Internship for 4 credits. Students usually complete the internship in the summer, but may enroll in the internship credits during the spring semester. If a student completes their internship during summer, they often work 40 hours/week for 10 weeks.
The PSM faculty advisor and ESS internship coordinator mentors and coaches each student throughout the internship placement process. Students learn how to:
- Identify and apply for positions
- Network with prospective host organizations
- Develop a professional resume
- Develop a professional LinkedIn profile
How do I find an internship?
PSM faculty and the internship coordinator help identify places to intern and assist you with making connections when applicable. However, each student is responsible for finding, applying to, and finalizing placement in their internship. The ESS 587 curriculum empowers PSM students with meaningful job-related skills in resume building, interviewing, and professional networking.
Where do PSM graduates typically find employment?
Our graduates have gone on to work in an array of private and public institutions such as:
- Colorado Department of Public Health and Environment
- Northern Colorado Water Conservancy District
- Northern Water
- Brilliant Earth
- Dewberry
- American Carbon Registry
- Winrock
- The Nature Conservancy
- Ducks Unlimited
