How to Advance Your Career in Data Science
The two most prominent ways to advance your career in data science are to complete additional education and obtain relevant professional experience. Since data science careers require advanced skills in specialized fields like machine learning, data mining, and statistics, these professionals strongly benefit from earning a graduate degree.
Internships, fellowships, and other professional development opportunities help students and recent graduates gain practical field experience. Students may also seek out jobs as research assistants to help offset the cost of their education while gaining valuable skills. Additionally, aspiring scientists may consider postdoctoral research.
Individuals can also consider obtaining certifications, pursuing nondegree educational opportunities, and joining professional organizations.
Certifications and/or Licensure
Certifications are typically optional credentials issued by professional organizations, while licenses are typically mandatory permits issued by government agencies. Most data science careers do not require professional licenses.
Certifications demonstrate concrete skills and expertise. As such, they are attractive to employers. There are several professional certifications relevant to the field of data science, including the certified analytics professional, certified professional data engineer, certified data scientist, certified advanced analytics professional, and senior data scientist credentials, which are offered by various organizations.
Many big data companies also offer their own certification programs. Examples include Google's professional data engineer certification, Dell's data science associate certification, and Microsoft's Azure data scientist associate credential.
Professionals may also seek out certifications in specialized subfields of data science. For example, the American Health Information Management Association offers the certified health data analyst credential and the International Institute of Business Analysis offers the business data analytics certificate. These specialized credentials may be especially useful for learners who complete a degree in data science that does not offer a concentration in their area of interest.
Although degrees are the most common form of education for data science professionals, many schools and organizations offer nondegree continuing education opportunities. These options typically feature a short course or sequence of courses. As such, learners can complete them in a much shorter amount of time than a traditional program.
Online learning platforms like Coursera and edX offer several free or inexpensive programs. For example, IBM's data science professional certificate, available through Coursera, imparts skills in SQL, Python, business intelligence, and statistical analysis.
Nondegree certificate programs at colleges and universities allow learners to access the institution's academic and professional resources without committing to a full degree. Many schools allow learners to apply certificate credits toward a degree later on, if they so choose. Like certifications, certificates can be particularly useful for helping individuals gain experience and credentials in specialized subfields of data science.
There are myriad options available. For example, Harvard University offers a data science graduate certificate, Massachusetts Institute of Technology offers a professional certificate in machine learning and artificial intelligence, Pennsylvania State University offers a certificate in business analytics, and Arizona State University offers an advanced analytics in higher education graduate certificate.
Outside of educational opportunities, students and professionals can advance their career in data science by networking, joining professional organizations, participating in conferences, and conducting original research.
Professional organizations host events, disseminate the latest research in the field, maintain job boards, and advocate for their members. Many professional organizations provide scholarships and fellowships to students and postdocs. They may also deliver continuing education opportunities, such as certificate programs and webinars. These opportunities are particularly important because many professionals need to complete continuing education credits on a regular basis to renew their certifications.
Additionally, since data science is a rapidly evolving field, professionals must stay abreast of the latest research and technologies. Reading industry magazines, academic journals, and other publications can benefit students and experts alike.
