GRE, TOEFL, or No Test? How to Approach Standardized Tests for MS in Data Science

Standardized testing for an MS in Data Science in USA is no longer as simple as preparing for the GRE and TOEFL because every university requires them. Requirements now vary considerably. One program may require the GRE, another may make it optional, and another may not consider it at all. English-language testing has its own rules and possible exemptions.

For students applying from India, this makes checking requirements university by university essential. While a strong test score may be helpful where accepted, the effort of months of preparation for an exam that is not required for admission to the programs you are applying to is not very beneficial.

How to Approach Tests For MS in Data Science?

The following steps can help you decide which exams to take and how much time to spend preparing for them.

1. Start With The University List

It is easy to register for the GRE first and shortlist universities later. For data science applicants, reversing that order can save both time and money. Testing policies differ even among well-known US universities.

Stanford’s Statistics MS/Data Science application currently requires the General GRE for external applicants, while NYU’s MS in Data Science makes the GRE optional. Columbia lists GRE General Test scores as optional for its 2026 MS Data Science applications.

This is why there is no single answer to whether you need the GRE for a Master in Data Science. Create your initial university list first. For each program, indicate if the GRE is required, optional, or not taken into consideration.

2. When Does Taking the GRE Make Sense?

If even one of your preferred programs requires the GRE, the decision is simple: you will need to take it unless you qualify for a stated exemption. The decision becomes less obvious when all your shortlisted programs make it optional.

In that situation, look at the rest of your application. A strong GRE score may provide another piece of academic evidence, particularly if you want to demonstrate your quantitative preparation. But an optional test should not take so much preparation time that your university coursework, projects, statement of purpose, or applications suffer.

If you decide that the GRE is worthwhile, GRE classes in Mumbai may provide structure for guided preparation. Others may be comfortable preparing independently. Choose based on how you study rather than assuming coaching is necessary for everyone.

3. What About the TOEFL Test?

The TOEFL test is mainly about your English proficiency, while the GRE looks at a different set of academic skills. So, even if the GRE is optional for a program, you may still need to meet the university’s English-language requirement separately.

Some universities allow exemptions based on previous education in English. NYU, for example, states that TOEFL or IELTS can be waived if an applicant’s bachelor’s or master’s degree was completed at an institution where English was the language of instruction. Stanford also lists circumstances in which applicants can meet its English proficiency requirement without submitting a test.

Do not assume that studying your bachelor’s degree in English automatically exempts you everywhere. Each university sets its own conditions and may ask for particular evidence.

4. Do Not Build Your Entire Application Around Test Scores

Test scores may supplement your application, but they’re not the only factor that universities take into account. The grades, coursework, statement of purpose, recommendations, projects, and research and work experience can all have a role in the decision.

Spend enough time on testing to meet requirements and represent your abilities well, but leave enough time for the rest of the application too.

An experienced Study Abroad Consultancy in India can help organise university-specific requirements, but always verify current testing policies on the program’s official admissions page before submitting your application.

FAQs

Is the GRE required for MS in Data Science in USA?

It depends on the university. Some programs require it, while others have made it optional. Stanford’s Statistics/Data Science MS currently requires the General GRE for external applicants, whereas NYU’s MS Data Science lists it as optional.

Do Indian students need the TOEFL test for MS in USA?

Many US universities require international applicants to demonstrate English proficiency, but exemptions may be available depending on previous education and the university’s rules. Check the exact policy of every program before registering for the TOEFL test.

Should I submit my GRE score if it is optional?

Consider the strength of the score and the rest of your profile. If your score adds useful evidence of quantitative ability, submitting it may make sense. If not, put that time into the parts of your application that the university will actually review, such as your academic record, technical work, and other required documents.

When should I start preparing for GRE and TOEFL?

Check the deadlines of your short-listed universities, then start backwards. You will have time to prepare, take tests, and send your scores a few months earlier than the deadline.

Conclusion

There is no standard testing route for every MS in Data Science in USA applicant. Start with the universities that you are sure to apply to. By knowing their requirements, you will know whether you should take the GRE, the English proficiency test, or none of them. However, be sure to look closely at every program for exemptions as well, to avoid taking the time to prepare for a test that may not be required.
