DOE CSGF Essays and Program of Study: 2027 Guide

DOE CSGF Essays and Program of Study: 2027 Guide

DOE CSGF applications for the 2027–2028 incoming class are due Thursday, January 7, 2027 (the application FAQ gives 5:00 PM CST). The public pages require a Program of Study that covers three subject areas plus one high-performance computing course, and they name a Personal Statement. The essay questions themselves are inside the application portal.

It is tempting to treat the essays as the application. For the CSGF, the Program of Study is the part that is fully public and fully binding, and it is the part you build with an advisor. Our view: draft the Program of Study first, then write your statement as the argument for it. A statement that sells one discipline's research and never explains the computing or the course plan argues against the structure the fellowship requires. When you have a draft, a PhD statement of purpose review is one way to check that the story holds together.

Every Krell Institute page quoted below was checked on October 29, 2026, when the CSGF home page read "The 2027 application is now open!" We did not register for a portal account, so this page does not quote, paraphrase or guess at the essay questions. If you are also weighing federal and foundation awards, the GRFP, NDSEG and Hertz season guide covers how they fit together.

What is public and what is only in the portal

The How to Apply page and the application FAQ describe the parts of the application. Here is what each says, and where the rest lives.

Two portal facts are public. "Your application is not submitted until you press 'Final Submission'", and "You can check the version of the application that will be seen by reviewers using the Preview button on the Application Dashboard." Read that preview with the Program of Study and the statement side by side.

Pick the track before you write a word

The track sets what your research must be about. From the Math & Computer Science Track page and the Fields of Study page:

Three rules settle most edge cases:

1. CS, CE or EE research with no specific science application goes to Math/CS. The Fields of Study page says such students "should apply to the Math/CS Track as these topics are considered broadly applicable research areas".
2. Quantum information science splits by what you build. Students using "scientific computing for the design and/or control of quantum information systems, should apply to the Science & Engineering track." Students "pursuing research focused on algorithms or software for QIS" may apply to Math/CS, including from a physics department.
3. Not sure your field counts? The FAQ says that if your area "does emphasize high-performance computing, you are encouraged to apply and convey to application reviewers that your work can be properly represented as computational science."

What each track's statement has to carry (our recommendation):

• Science & Engineering: the science question first, then why answering it needs computing at a scale you cannot reach today.
• Math/CS: the method or tool first, then the science applications that would use it. The Krell page says the science courses in a Math/CS POS exist "to ensure that the fellow is exposed to the computational needs of science and engineering applications that will use these new broadly applicable methods and technologies." Your statement should name those needs too.

The Program of Study rules, verbatim

The Program of Study page (the page states no cycle year) sets the core rule:

The POS must provide a solid background in (1) a scientific or engineering discipline, (2) mathematics and statistics and (3) computer science and computer engineering. Fellows' major fields must fall into one of these categories, but they also must attain high marks in the other two to demonstrate that their POS has sufficient breadth. A course that introduces the concept of high-performance computing is also required and may be taken from any department with a preference given to those in computer science.

The rest of the rules, from the same page and the FAQ:

Our arithmetic: on a semester system the minimum POS is 2 + 2 + 2 + 1 = 7 courses; on a quarter system it is 3 + 3 + 3 + 1 = 10. The sample POS on Krell's page lists exactly seven semester courses. If your POS has seven courses, no more than three can be finished before the fellowship starts, because half of seven is three and a half.

If you are a senior, the FAQ says to "assemble a POS for the university that you want to attend", ideally reviewed by a graduate advisor there, or by "your current undergraduate advisor" if that is not feasible. If you win and attend somewhere else, you submit a new POS. The program also says: "The person listed as your advisor within the application will not be contacted".

How the Personal Statement should use the Program of Study

The questions are in the portal, so these are recommendations, not a reading of the prompts. They rest on what the public pages say fellows must show each year. The annual renewal application demonstrates that fellows are "progressing toward completing approved program of study coursework", have "completed a laboratory practicum experience" and are "conducting research in fields of study relevant to the DOE" (Eligibility & Program Requirements). The benefits page describes the practicum as "A 12-week practicum experience at one of 21 DOE national laboratories or sites" (Benefits & Opportunities).

1. Name the computing bottleneck in your own work. One sentence on what you could not run, resolve or scale, and why.
2. Point to the POS rows that close it. At minimum the HPC course and one course outside your major area. Use the same course titles the POS uses.
3. Say what you would want from a DOE laboratory practicum. A skill or a scale, not a lab name you cannot justify.
4. Use the statement for anything else reviewers should see. The FAQ routes supplemental information there, because attached files "will not be reviewed."

The countercase: if the portal splits the statement into several questions, answer each one as asked. Our alignment advice applies to the application as a whole, not to every answer. A leadership or background question should not be forced into a course list.

Constructed example: one paragraph and the matching POS rows

Constructed example, written by us, not a real applicant statement. The applicant, the universities, the course numbers and the results are invented.

Context (invented): a senior in mechanical engineering applying on the Science & Engineering Track, planning a PhD on ocean circulation modeling at "Westbrook University". Westbrook runs semesters, so the POS needs two courses in each area and one HPC course.

The plan obeys the rules above: seven courses, one of them taken before the fellowship (fewer than half of the seven, and the only one in its area), the HPC course in its own section, and the machine learning course listed under computer science, where its content aligns with that area.

Weak version of the statement paragraph:

My research interest is ocean circulation and climate. I want to understand how the ocean stores heat because this is important for predicting climate. In my undergraduate research I ran simulations of ocean currents and learned a lot about fluid dynamics. At Westbrook I hope to continue this work and become a leader in climate science.

Revised version:

My senior thesis model of a wind-driven ocean basin hit a limit I could not code around. Halving the grid spacing to resolve the eddies I was studying made each run about eight times slower on our department's 64-core cluster, so I could finish one resolved case a week. That is why my Program of Study pairs Geophysical Fluid Dynamics with Parallel Computing and Numerical Methods for PDEs, which I am taking this fall for graduate credit. The science question needs the resolution, and the resolution needs a parallel solver I can write and test myself. A DOE laboratory practicum is where I would learn how that solver behaves on a far larger machine.

The revision is 114 words. It names the bottleneck, cites three POS rows by their titles, and gives the practicum a job. The weak version could be pasted into any fellowship application, which is the problem.

Eligibility traps to check before you start

From the Eligibility & Program Requirements page and the FAQ:

The federal-fellowship rule matters if you also applied for the GRFP or NDSEG this fall. Read how external fellowships interact with a PhD stipend before you count two awards.

Letters, transcripts and the final-submit lock

• Submit on time even if letters are missing. "Please final submit your application by the application deadline, even if some of your supporting documents are outstanding." Letters are due "by Jan 07, 2027 at 5:00 PM CST", but the letter portal "will remain open throughout the application review process."
• Transcripts must come from the university ("Transcripts sent by an applicant will not be accepted"), by January 7, 2027 at 5:00 PM CST. A late fall 2026 transcript is "very common"; no need to contact the program if it arrives by the end of February.
• No edits after submission. "Once you have submitted your application, you cannot make changes to it."
• Results: "You will be notified whether or not you received a fellowship by early April." The fellowship starts September 1, 2027. The home page lists "A yearly stipend of $45,000", and the benefits page lists "Payment of full tuition and required fees during the appointment period".
• Reapplying: "We do not retain applications from year to year."

Checklist before final submission

1. Choose the track using the three rules above, and write the choice into your first paragraph.
2. Draft the POS with an advisor: two courses per area (three on quarters) plus one HPC course.
3. Check that no more than half the POS, and no more than one course per area, is already done.
4. In the statement, name the computing bottleneck and cite the POS courses that close it.
5. Say what a DOE laboratory practicum would add to your training.
6. Put any extra context in the Personal Statement; attached files are not reviewed.
7. Ask three writers for new letters written to the reference form.
8. Open the Preview, read the POS and statement together, then press Final Submission.

Questions about the DOE CSGF application

Are the DOE CSGF essay prompts public?

No, not on the public pages we checked on October 29, 2026. They are inside the application portal.

Can I apply to the DOE CSGF as a second-year PhD student?

No. The eligibility page lists "Second-year or beyond graduate students" as not eligible.

Does the DOE CSGF use GRE scores?

No. The FAQ says standardized test scores "will not be considered as part of the review and selection process."

Can I reuse my NDSEG or GRFP essays?

The CSGF FAQ we checked has no rule on reusing your own material. Each program sets its own document rules, and only the CSGF statement sits next to a Program of Study, so rebuild it around your POS. Our NDSEG essays guide, Hertz application guide and GRFP cycle guide cover those contracts. Applying to an NIH F31 or F30 as well? NIH rebuilt its candidate section in 2025; see what replaced the F31 Applicant's Background and Goals.

Biomedical applicants weighing an NIH fellowship can compare this with a constructed F31 Specific Aims example.

Get a free review of your DOE CSGF personal statement

Get a free Quick Review of your DOE CSGF personal statement against GradPilot's PhD SOP research dossier rubric. There is no CSGF-specific rubric; this is the closest match. It reads whether each research episode has a problem, something you built or tried, a decision and a result, whether you name one next problem, and whether you say what that problem needs at the receiving program. Paste the portal's question and its limit with each answer. For an engineering-field statement, the engineering PhD statement of purpose rubric reads your contribution and your technical choices; the general PhD statement of purpose rubric reads the whole statement.
