Many computer scientists started out as mechanically inclined “tinkerers,” people who enjoy learning how something works and pushing the boundaries of their understanding. Take Bill Gates, for example. As a teen at Lakeside Prep School in Seattle, Washington, the Microsoft co-founder often skipped class to write his first computer program. It powered a human vs. machine tic-tac-toe game.

Decades later, he wrote: “I was 13 years old when I fell in love with programming. My school had just become one of the first in the country to get a computer terminal. The machine was huge and slow, and it didn’t even have a screen—but I was hooked.” While computers looked much different when Gates was a teen, their ability to help students explore their creativity remains unchanged. These days, there are more computer science programs than ever devoted to doing exactly that.

A robust job market for computer science graduates helps drive enrollment trends in computer science degree programs. According to the US Bureau of Labor Statistics (BLS), the number of computer and information technology (IT) jobs is projected to increase by 12 percent through to 2028, the result of a growing emphasis on cloud computing, the collection and storage of big data, and information security.

BLS data also show that many common career paths among computer science degree-holders lead to six-figure salaries. For example, in 2019 the median annual income among professionals who held the title of database administrator was $93,750. Software developers and computer network architects did even better, making a median $105,590 and $112,690, respectively.

Add in ample research opportunities, specialization options, and the wide variety of convenient online programs available in the field, and it’s understandable why pursuing a degree in computer science may be on your mind. But how long will it take to complete? The answer depends on the degree path that’s right for you.
