If coding bootcamps are step one, new 12-week data science bootcamps from accredited parties are step two.

It seems that coding bootcamps are so 2015. For students eager to get into a burgeoning field that pays well, data science bootcamps promise to be the new oases amidst hiring deserts.

Starting this summer and continuing throughout the fall, third-party hosts, such as Metis and NYC Data Science Academy (NYCDSA), are offering 12-week programs in data science for students that have some beginner’s knowledge of coding and/or statistics.

The impetus behind these trending data science bootcamps, say creators, is largely due to reports from career research websites, like Glassdoor, which say positions in data science fields not only aren’t getting filled—leading employers to offer high-paying salaries—but will only increase in number of positions available in the future, providing stability within the field.

Data Science is an increasingly interdisciplinary field about processes and systems to extract knowledge or insights from data in various forms, either structured or unstructured, which is a continuation of some of the data analysis fields such as statistics, data mining, and predictive analytics, similar to Knowledge Discovery in Databases (KDD). The field can also relate to data administration, or data resource management, as an organizational function working in the areas of information systems and computer science that plans, organizes, describes and controls data resources.

According to Glassdoor, the average base salary of a data scientist is $105,395, with the number of current job openings exceeding 3,400. A database administrator’s average base salary is currently $97, 258, with the number of job openings over 9,000. [Read: “3 blossoming fields of study with massive potential.”]

As data science and data analytics is embraced around the globe, however, the supply of data scientists is lagging far behind burgeoning demand. According to McKinsey, the U.S. will experience a shortage of up to 190,000 skilled data scientists by 2018 due to the ongoing data deluge. The projected heavy shortage of data scientists has universities around the world scrambling to put together data science programs.

This is fine for those now entering the college system, but what about the thousands of students who have graduated with a degree in a similar field and want to prepare themselves for the data science boom?

That’s where data science bootcamps come into play.
