August 23, 2021
If you're a data science professional considering earning your master’s, you may be tempted to look at cheaper and faster certificate programs. But how do they really stack up against master’s programs and will they help advance your career?
If you're interested in earning a data science master’s, you’re already aware that this is a rapidly expanding field with numerous job opportunities and a median annual salary of $ 111,490. Yet, even though you know that obtaining this degree is an excellent way to advance your data science career, you may be hesitant about the cost, time, and effort involved—and are considering a faster and cheaper certificate program.
This article on data science master's vs. certificate programs examines the pros and cons of each option and covers subjects like:
- Which is better: a data science master’s or certificate (or both)?
- What is a data science master’s degree?
- Best programs to earn a data science master’s?
Which is better: a data science master’s or certificate (or both)?
A recent survey by Burtch Works found that 50% of the data science professionals had earned their master’s, and a study conducted by Stitch several years ago revealed that around 40% of data science professionals in both senior and chief leadership roles held master’s degrees. While earning a data science master’s may not be the sole path to a successful career in this field, these studies strongly indicate that possessing this advanced degree is definitely advantageous—and expected and/or required in many upper-level data science positions.
If you’re applying for an entry-level data science job, earning a certificate can be a good way to demonstrate to a prospective employer that you have some data science skills. Likewise, if you’re in a lower-level data science role and want to acquire a specific new skill that will help you become better at your job and be seen as a more valuable asset to your employer, a data science professional certificate is a good move. However, these are short-term career strategies (with short-term payoffs).
Below, you’ll find the pros and cons of both data science master's and certificate programs:
Pros of a data science master’s degree
- They are all-encompassing: A data science master’s will provide you an education that is both broad and deep, as well as prepare you for a rewarding career in this field.
- They are a known quantity: If you earned your degree from a top data science program, like those offered by the Stevens Institute of Technology, Tufts University, or the University of Virginia, an employer knows that you have been equipped with the knowledge and expertise to do your job effectively and well.
- They offer guided learning: You will have many opportunities to collaborate with professors and fellow students in your data science courses, especially during thesis, capstone, and group projects.
- They can connect you to great jobs: Top data science programs often provide excellent networking opportunities that can help you secure your ideal data science position.
Cons of a data science master’s degree
- They are expensive: Master's programs typically cost over $40,000, with tuition at top schools considerably higher (though the cost of this degree will be offset by the higher future earnings that you’ll command for the rest of your career).
- They are time-consuming: It generally takes around two years to complete a full-time master's program—and longer if you’re enrolled in a part-time course of study (though the investment of a few year’s time now will pay off for decades).
- They are comprehensive: If you're only looking to acquire skills in one limited area, you don’t want to spend the time and money enrolling in a master’s program.
Pros of a data science certificate program
- They are inexpensive: Most programs cost just a few thousand dollars to complete—though they can run more than $10,000.
They are quick: Though some certificates can take more than a year, most take just a few months to complete.
- They sometimes count towards a master's: Credits earned through some certificate programs can transfer if you decide to pursue your data science master’s.
- They offer targeted learning: Certificates allow you to focus on one specific subject, like big data or machine learning.
- They can be offered by top programs: Many top schools offer data science certificate programs, including Harvard University, Northwestern University, and University of Michigan.
Cons of a data science certificate program
- They aren’t equal to a master’s: It’s apples and oranges. Certificate programs are nowhere near as comprehensive and rigorous as a master’s, so their importance and value to employers (and your career) is significantly less.
- They will leave gaps in your knowledge: Even if you earn multiple certificates in data science, you will never achieve the breadth and depth of learning found in the curriculum of a degree program. They offer less support: Since certificates are fast, one-off affairs, the number of resources provided to students outside the class is minimal.
- They can be riskier: The quality-control of some certificate programs is sometimes questionable, so their perceived value among both participants and hiring managers can be low.
What is a data science master’s degree?
Simply put, data science is a computer science discipline that focuses on data. Data science professionals utilize advanced data analysis tools, such as machine learning, data visualization, artificial intelligence, and high-level statistical analysis to collect and interpret data sets.
Are there prerequisites for applying to a data science master's?
If you're applying to a data science master’s program, it’s beneficial to have at least two years of relevant work experience in data management, business analytics, or business intelligence. While there are programs that accept inexperienced applicants—those with a bachelor's degree in an unrelated subject looking for a career change—it’s likely you’ll be required to complete bridge coursework, in addition to your regular course of study.
A basic understanding of one or more of the top computer programming languages (Python programming, R programming, SQL, or Java) will bolster your application, and knowing how to manage data structures is helpful. In addition to specific programming skills, many data science program applicants have worked as data analysts and possess the skills and experience necessary for that role.
Overall, applying to a data science program is similar to other master’s programs, including submitting personal statements, letters of recommendation, and undergraduate transcripts. You'll also likely send in GRE scores, though many programs no longer require them, especially those offered online. Even highly regarded schools like Tufts University are loosening their standardized test requirements in favor of a more holistic approach to admissions, favoring related work experience over test scores.
What do you learn in a data science master's degree program?
