THE 21-DAY DATA CHALLENGE ENDED ON MAY 1ST, 2022. You can continue to practice at your own pace but no prizing is available.

What is the 21-Day Data Challenge

In today's job market, data skills hold great value. They can help you build your career and stand out in an increasingly competitive job market.

The wide applicability of data skills is why they've become so valuable. But developing a new skill can seem daunting. You've probably already worked with data in some shape or form, reviewing a statistics spreadsheet or managing customer data. To truly learn how to master data, you need to dive right in and immerse yourself in it. You need to commit to practicing every day.

That's why Lighthouse Labs created the 21-Day Data Challenge. By spending just 30 minutes a day working on these challenges, you can build up your data skills. The challenge is fun, free, and filled with rewards. You'll have the chance to win some really exciting prizes!

How much experience do I need

None at all. For those completely new to data, we've created some resources that will help you prepare for the daily challenges. Plus, you'll have access to a community forum where you can get hints and tips from fellow participants and our team of mentors.

We'll Help You Prep

How does it work

Starting April 11th, 2022, you'll have 21 days to build a data practice working your way through our challenges. Each daily challenge will take 30 minutes to complete, and they're designed to be fun! You'll play as Dot, who leaves their home in Vancouver to embark on an around-the-world adventure. You'll learn and use skills in Python, SQL, and Pandas to help Dot solve problems in Dubai, Tokyo, Barcelona, and more.

These challenges are designed to encourage your daily data practice and to help you stick to it, we are giving away special daily prizes! If you miss a day or two here and there, no worries: you can still catch up, though you will lose out on the chance to win the daily prize giveaway.
