Data Science Masters

We’re delighted that you are considering applying to the University of Washington Master of Science in Data Science program!

Our application deadlines for the Autumn 2024 intake have now passed. We do not accept late applications for any reason. Please note that we admit students once per year for the Autumn quarter only.

For students who wish to apply in the next application cycle, the application opens in late September/early October 2024 for the Autumn 2025 intake. The deadlines for the MSDS application have not yet been decided for the 2024-25 admissions cycle, but are generally in January.

Admissions Requirements

4-year U.S. Bachelor’s degree or equivalent

Applicants are required to have a four-year bachelor’s degree from an accredited institution in the United States or its equivalent from an international institution. If you have a 3-year undergraduate degree, please contact the central UW Graduate School to clarify if your education will meet the requirement.

3.0 Minimum GPA from last 2 years of graded full-time study

Applicants are required to have a GPA of at least 3.0 for the last 60 graded semester credits or the last 90 graded quarter credits of their schooling (U.S.), or roughly the equivalent of the last two years of graded study (undergraduate and/or graduate). If you need help converting an international GPA to the 4.0 U.S. scale, you can use the grade conversion tool provided by the UW Graduate School, or you can use a GPA from another international GPA translation service (WES, Scholaro, etc.) if your grading system is not represented on the UW Graduate School tool.

If you have less than a 3.0 GPA for the last 2 years of graded full-time study, it is still possible to be admitted if you are an otherwise outstanding candidate for our program. If you are in this situation, please use the “Additional Information” section of the application to address what happened that caused a lower GPA, and why you might be a successful graduate student in our program despite a lower GPA. This 3.0 minimum is a requirement of the central UW Graduate School for all graduate school applicants, and we can petition for an exception for candidates we wish to admit with a lower GPA. We have successfully petitioned for exceptions to this requirement in the past.

No GRE or GMAT used in our holistic admissions process

We found that the GRE and GMAT were not good indicators of success in our program, so we do not accept GRE or GMAT scores as part of our application process. There is no benefit to providing GRE or GMAT scores with your application.

Prerequisite skills in Computer Science and Mathematics

As an interdisciplinary program, the MSDS curriculum includes graduate courses taught by faculty across multiple disciplines relating to data science. Students need core skills in Computer Science and Mathematics in order to succeed in these courses. Offers of admission will only be made to applicants who demonstrate strong competencies in these essential areas and skills.

Please see our Prerequisite Skills page for required skill areas as well as how to document these. In short, each applicant must document these Computer Science and Mathematics skills through either:

  1. Completed, graded, for-credit coursework that covers listed skill areas.
  2. Letter from a technical professional documenting these skills in specific projects.

Deadline Policy: no late applications or materials accepted

The UW MSDS program accepts students once per year for the autumn quarter intake. Applications must be received by the deadline to be considered. (Our deadlines have not been decided for 2025 but will be posted when available. Deadlines generally fall in January the year of admission.)

All materials must be submitted by the deadline, with the exception of recommendations which may be received up to 2 weeks after the respective deadlines. We do not have rolling admissions or priority deadlines.

We do not accept late/incomplete applications, or late application materials.

Application Materials

Online UW Slate application

Applicants are required to upload all application materials to the online Slate application system.


We are currently assessing our essay questions for the 2024-25 admissions cycle, which will be announced later in the summer. These short essays are an opportunity to articulate your candidacy for the Master of Science in Data Science program at the University of Washington. The best essays are clear, succinct, thoughtful, well-written, and engaging. Your essays play an important role in our holistic admissions process, and we expect that they are your own original work.

When available (late summer 2024), the MSDS essay questions will be posted on this website, and in the Slate MSDS application.

Unofficial digital transcripts

Applicants must upload unofficial transcripts/marksheets from every institution where they earned a degree or completed prerequisite courses. These are generally .pdfs, scans or other images. Transcripts and degree documents that are in a language other than English must be accompanied with an official English translation (translated by a university, government official/organization, or a certified translation service, example: American Translators Association).

We do not need or accept official/paper transcripts or other documents during the initial admissions process. If you are admitted and accept your offer, the central UW Graduate School will contact you about where/how to send required official materials sometime during the summer before you start classes.

Short resume or CV

We are looking for a concise summary of your professional and other credentials. It is strongly recommended that applicants limit their resume to one page, single-sided, with a specific focus on data science credentials and related jobs or internships.

Letters of recommendation: 2 required, 3 preferred

Letters of recommendation are collected by our recommendation system, once you have entered your recommenders in the online Slate application. Each recommender receives an email invitation to submit their recommendation via the UW’s Slate portal. They may upload their letter of recommendation into the system, as well as answer questions about your candidacy.

It’s a good idea to designate your recommenders as soon as you’re able, so they can start submitting their recommendations for you and have more time to do so. This can happen while you are still finishing your application, and have not yet finalized or submitted it yet.

Note: Interfolio and other recommendation aggregators are not directly compatible with UW’s Slate system.

Documentation of CS and Math skill proficiencies

All applicants are required to document how they meet the prerequisite skill requirements in the Additional Information section of the online application. Please refer to the Prerequisite Skills page for Computer Science and Mathematics skills/knowledge required, as well as the accepted forms of documentation.

Proof of English proficiency (for non-native English speakers)

There are many ways to prove English proficiency, as noted in UW Policy 3.2 which spells out the UW English Proficiency Requirement. Please note that the UW MSDS program’s requirements are higher than the central UW Graduate School. Here are the main ways to prove English proficiency for the MSDS application:

  • An undergraduate or graduate degree from a regionally-accredited institution located in the US, UK, Canada, Australia, or other country where English is the official language, and English is the medium of instruction.
  • Official documentation from the applicant’s undergraduate institution verifying that all of their instruction was completed in English. Usually this shows up as a note on a transcript or separate letter from the institution that simply states that “the medium of instruction was English.”
  • TOEFL scores with a minimum 106 total score and 25 in each area test. Official test scores must be sent directly to UW from ETS, using institution code 4854. UW does not use department codes, as all scores go through the central UW Graduate School. You may choose any department code and scores will be transmitted to all programs to which you apply via the Slate online application at UW. *Please note that transmission of electronic scores is not instantaneous and applicants should transmit their scores as soon as they can.
  • DuoLingo scores with a minimum 125 total score. Official test scores must be sent directly to UW from the testing company.
  • Electronic IELTS scores sent directly from the testing company, with a minimum score of 7.5. Applicants using ILETS test scores must submit official scores electronically via the IELTS system (E-TRF), using the University of Washington’s Recognizing Organizations (RO) ID 365. *Please note that transmission of electronic scores is not instantaneous and applicants should transmit their scores as soon as they can.
  • Applications without proof of English Proficiency within two weeks of the international deadline cannot be considered for admission.

Many international applicants do not realize that if they have completed their undergraduate education entirely in English, and can document this, UW does not require any test scores at all. All you need to provide is the documentation, which usually consists of a note your transcript or separate letter from your undergraduate institution that your “medium of instruction was English.” In this case, providing test scores has no benefit at all for your application.

If this documentation is in the form of a separate letter, you can combine this with your transcripts into a single file/.pdf and upload that in the transcripts section of the online application.

$90 Application fee

The central UW Graduate School collects an $90, non-refundable application fee for all graduate program applications to UW. Application fee waivers are available from the UW Graduate School to some domestic students who demonstrate financial need. Unfortunately, international students planning to study on a student visa are not eligible for these fee waivers.

Some applicants may be eligible for a pre-paid application fee, if they are part of certain pipeline programs. Please see our MSDS Application Fee Waiver and Pre-Payment page for more information.
