How 'official' are your certificates?

What data science certificate is really official?

There is no such thing as a "proven" certificate in data science — unlike a field like Law or Medicine, there's isn't an officially accepted set of criteria that determines whether someone can be a data scientist or not. Any certificate telling you otherwise is misleading, at best. 

While the Dataquest certificates you earn are great for showcasing skills you've acquired. What employers will be impressed by is the quality of your portfolio and how well you communicate your work to others.

Luckily, that's what we're all about.

We've blogged about the entire process of building a good portfolio  here: it's a 6-part series that will clear up many, if not all, of the questions you might have about the portfolio-building process. 


Our biggest advantage to students is that we get you started on building a great portfolio with our guided projects. We currently have over 30 of these guided projects, and we add more monthly. Rather than teaching specific concepts, the guided projects take a particular data set and get you to perform a series of steps on them, giving you a feel for what a proper data workflow is like, and leaving them open for extended analysis as you improve your data skill set.

Once you’ve finished, you can download the project to create a portfolio, which is a great way to showcase what you know to prospective employers.
