How do I know if the computer science graduate program is right for me?
Harvard Extension School does not require any specific skills prior to applying, but because this is an advanced degree, it is helpful to have an undergraduate degree in computer science, mathematics, or a related field, as well as some work experience in a technical field. Proficiency in programming languages — Java, Python, C++ — is recommended, and you should possess excellent problem-solving skills, attention to detail, and critical thinking abilities.
Who pursues the master’s degree in computer science?
Students in the Computer Science Master’s Degree Program are accomplished professionals from a range of technical and nontechnical backgrounds. Many are looking to deepen their expertise in software engineering and emerging technologies, while others are building the advanced skills needed to move into more senior or specialized roles.
What can you do with a master’s degree in computer science?
A master’s degree in computer science can help you build both a strong theoretical foundation and practical skills to support the next step in your career in one of today’s most in-demand fields.
Graduates may pursue a wide range of roles, including software engineer, computer scientist, database administrator, and software architect. Opportunities are not limited to the technology sector. Computer science skills are applicable across industries such as finance, government, and healthcare.
You may also explore emerging areas such as cloud computing, artificial intelligence, and data-intensive systems, depending on your interests and previous experience.
Is a degree in computer science useful?
A degree in computer science can help you develop software engineering, systems thinking, and problem-solving skills, along with a deeper understanding of algorithms, data structures, and modern computing technologies. As organizations increasingly rely on data, software, and computing systems, these skills are relevant across a wide range of professional contexts.
In addition, some mid- and senior-level roles may require or prefer candidates with a master’s degree, particularly for positions that involve advanced technical knowledge or specialized expertise. The Bureau of Labor Statistics reports the median annual salary for computer scientists and related professions was $140,910 in 2024.
Whether you are starting your career, changing fields, or looking to grow in your current role, a master’s degree in computer science can support your professional development and help broaden your potential opportunities.
