Is a Degree in Data Science Useful?
A degree in data science may not be required to get started in the field, especially for entry-level programmers and data analysts. Degrees in software engineering, computer science, math, and statistics can give you the basic skills you need to start a career in data science.
However, a graduate degree in data science offers a combination of skills that can help you stay competitive in the job market. In addition to programming and statistics, for example, a degree in data science offers advanced knowledge of modeling, data visualization, data analysis, and business intelligence.
Moreover, many mid- and senior-level positions such as data scientist or data architect for example, as well as most management positions, may require a master’s degree in data science.
Is a Career in Data Science a Good Career?
As organizations harness new technologies to gather and collect information more effectively, the demand for knowledgeable professionals with the skills to analyze that data correctly is growing—and quickly.
According to the US Bureau of Labor Statistics, jobs for data scientists and related positions are expected to grow 22 percent between 2020 and 2030.
And due to both growing demand and the complexity of the work, data science can be a lucrative career as well. According to Glassdoor, data science was the third-best job in the United States in 2022, based on median salary and availability of job openings.
How Long Does it Take to Complete the Data Science Graduate Program?
Program length is ordinarily anywhere between 2 and 5 years. It depends on your preferred pace and the number of courses you want to take each semester.
For an accelerated journey, we offer year-round study, where you can take courses in fall, January, spring, and summer.
While we don’t require you to register for a certain number of courses each semester, you cannot take longer than 5 years to complete the degree.
What Prerequisites Do You Need Before Applying for the Data Science Master’s Degree Program?
With Harvard Extension School’s unique “earn your way in” admissions process, there are no prerequisites required to begin your course of study in the data science master’s degree program.
To get started, you must complete two required courses that apply toward your degree: Foundations of Data Science and Engineering (CSCI 101) and Data Modeling (CSCI 106) or Introduction to Statistical Modeling (STAT 109).
However, to qualify for the master’s program, you must have prior knowledge of calculus and be able to write functions in Python and R. If you do not have these skills, it is recommended that you take Python (CSCI 7), Programming in R (CSCI 5A), and/or Calculus (MATH 15) before starting the degree program.
