MSc Data Science is one of the Master's programs in ETH Zurich's Department of Computer Science, at Switzerland's leading public technical university and a fixture in the global top 10 university rankings. Unlike ETH's Bachelor's degrees, which are taught almost entirely in German, most Master's programs including Data Science are taught fully in English, making this the realistic entry point for the large majority of international applicants without German fluency. ETH's genuinely distinctive draw for international students is its tuition: even after a 2025 fee increase, non-Swiss/EU students pay a still-remarkably-low CHF 2,190 per semester, a fraction of comparable US, UK, or Australian master's tuition, though Zurich's cost of living is among the highest of any city in this dataset.
This guide walks through what it takes to get into ETH Zurich's MSc Data Science: acceptance rate realities, cost, requirements, English-test rules, and what graduates go on to do.
Acceptance Rate
ETH Zurich does not publish a single university-wide Master's acceptance rate, since admission is decided per programme against programme-specific criteria rather than a single, holistic-review competition. What we know, grounded in ETH's own admissions structure:
- ETH's Master's admission is credential-based: applicants are assessed against programme-specific academic criteria (a closely related Bachelor's field, in Data Science's case typically computer science, statistics, mathematics, or a closely related quantitative discipline) rather than ranked against each other in a single admit-rate calculation.
- Data Science sits within ETH's Department of Computer Science, one of ETH's most in-demand departments internationally given the university's strong global research reputation, so applicants should expect genuine competition for a limited number of places even without an official percentage to quantify it.
- No official ETH-wide or Data-Science-specific acceptance rate exists publicly at the time of writing.
Bottom line: treat any specific "ETH Data Science acceptance rate" percentage quoted elsewhere with skepticism, since it is not a figure ETH itself publishes. Approach the program as genuinely selective given ETH's global standing, while recognizing that ETH's process is fundamentally a credential and fit assessment rather than a numbers-driven contest.
Fees and Cost of Attendance
| Cost Item | Amount (USD/year) |
|---|---|
| Tuition (Swiss/EU-linked rate) | $1,650 |
| Tuition (international rate) | $4,950 |
| Living expenses (Zurich) | $25,990 |
| Total estimated cost of attendance (international) | ~$30,940/year |
Over the full two-year MSc, that's roughly $62,000 in total cost of attendance before any scholarships, and living expenses, not tuition, dominate that figure: Zurich is consistently ranked among the most expensive cities in the world to live in, while ETH's tuition itself remains a fraction of comparable US, UK, or Australian technical master's programs. ETH charges a CHF 150 non-refundable application fee (~$170) per programme applied to.
ETH's flagship Excellence Scholarship & Opportunity Programme (ESOP) covers full tuition plus a CHF 12,000/semester stipend (roughly $13,560/semester) for living and study expenses, for the regular duration of the Master's program. Around 60 scholarships are awarded per intake to applicants who rank in the top 10% of their Bachelor's cohort and meet Data Science's standard admission requirements, via a separate application submitted alongside the main Master's application by November 30.
Admission Requirements
ETH evaluates prior Bachelor's degree performance against programme-specific criteria rather than a single university-wide GPA scale. Based on ETH's published Master's requirements:
- eApply online application
- Bachelor's degree transcript and diploma, assessed against Data-Science-specific admission criteria; a Bachelor's in computer science, mathematics, statistics, or a closely related quantitative field is generally required
- IELTS Academic or TOEFL iBT scores, for this English-taught programme
- CHF 150 non-refundable application fee per programme applied to
- Motivation letter and/or CV, required by some (not all) departments
ETH's application window for Bachelor's degree holders from outside Switzerland is 1-30 November for the following autumn semester, with ESOP decisions specifically communicated by end of March. ETH does not require GRE or GMAT scores for its Master's programs generally.
How to Get Into ETH Zurich's MSc Data Science
-
Make sure your Bachelor's degree is a close quantitative match. ETH assesses your prior degree against programme-specific criteria, and Data Science generally expects a Bachelor's in computer science, mathematics, statistics, or a closely related field rather than a loosely adjacent background.
-
Aim for the ESOP scholarship tier if you're a strong student. Ranking in the top 10% of your Bachelor's cohort qualifies you to apply for ETH's Excellence Scholarship, a genuinely transformative award (full tuition plus a substantial living stipend) that requires a separate application submitted alongside your Master's application by November 30.
-
Highlight applied statistical or machine-learning work in your motivation letter. Where required, use concrete examples, coursework projects, research assistantships, or independent analysis work, to connect your background directly to ETH's Data Science curriculum.
-
Apply within the November window, not after. ETH's application period for non-Swiss Bachelor's degree holders is a fixed 1-30 November window, considerably narrower than the rolling admissions common at many universities, so missing it means waiting for the next intake cycle.
-
Clear the English proficiency bar comfortably, not exactly. ETH's discussion- and report-heavy project culture expects strong written and spoken communication from day one; a stronger-than-minimum score removes any doubt about your readiness for coursework taught entirely in English.
English Proficiency Requirement (IELTS/TOEFL)
ETH's Bachelor's programmes are taught almost entirely in German, so IELTS/TOEFL are not the relevant test at that level. At Master's level, where Data Science is taught in English, the standard is:
- IELTS Academic: commonly required standard of 7.0 overall, no band below 6.5 (IELTS General Training is not accepted, only IELTS Academic)
- TOEFL iBT: commonly required standard of 100 overall, no section below 23
ETH does not publish one single university-wide minimum; each Master's programme sets and publishes its own required score, so always confirm the exact figure for Data Science specifically before applying. TOEFL and IELTS certificates must be no more than two years old at the time of application, and ETH does not offer conditional admission or a bridge/pathway English program at Master's level.

Career Outcomes
ETH does not publish graduation, employment, or starting-salary figures broken out specifically for MSc Data Science, so treat any precise number quoted elsewhere with caution. What is well documented:
- ETH's graduate-level (Master's) reported recruiter relationships include Google, McKinsey & Company, Roche, Novartis, UBS, and Credit Suisse/UBS Group, reflecting strong demand for data-science skills across both the technology sector and Switzerland's globally significant pharmaceutical and financial-services employer base.
- ETH's Nobel Prize history is unusually concentrated for a technical university: Albert Einstein earned his diploma in physics and mathematics at ETH in 1900, and more than 20 Nobel laureates have studied or worked at the institution, reflecting the depth of ETH's research culture that Data Science students train within.
- ETH's central Zurich location gives graduates direct access to Switzerland's largest city and financial center, alongside a genuinely international campus culture, with 42% of Master's students international.
FAQ
Does ETH Zurich publish an acceptance rate for MSc Data Science? No. ETH does not publish a single university-wide or department-specific Master's acceptance rate, since admission is decided per programme against programme-specific criteria rather than a holistic-review competition.
What IELTS or TOEFL score do I need for ETH's Data Science Master's? A commonly required standard is IELTS 7.0 overall (no band below 6.5) or TOEFL iBT 100 (no section below 23), but ETH sets exact thresholds per programme, so always confirm the current figure for Data Science on ETH's own admission page.
How much does ETH's MSc Data Science cost?
Tuition is CHF 2,190/semester ($4,950/year) for international students, a fraction of comparable US, UK, or Australian tuition. Total cost of attendance, including ETH's own CHF 20,000-26,000/year living-cost guidance ($25,990), is closer to $30,940/year, since living expenses in Zurich, not tuition, dominate the real cost of studying at ETH.
Is the GRE or GMAT required for ETH's Data Science Master's? No, not as a standard requirement. ETH Master's programmes generally do not require GRE or GMAT scores.
What is the ETH Zurich Excellence Scholarship? The Excellence Scholarship & Opportunity Programme (ESOP) covers full tuition plus CHF 12,000/semester for living and study costs, for the full regular duration of a Master's programme. Around 60 scholarships are awarded per intake to applicants who rank in the top 10% of their Bachelor's cohort; it requires a separate application submitted alongside the main Master's application by November 30.
Do I need IELTS or TOEFL for ETH's undergraduate degrees? Generally no. ETH's Bachelor's programmes are taught almost entirely in German, so German-language proficiency and your underlying school-leaving qualification matter far more than an English test at that level. ETH does not offer a standalone undergraduate Data Science degree; Computer Science is the closest Bachelor's-level equivalent.
