Free certificationPower BI Certification
A free, verifiable Power BI certificate you earn by building reports and writing DAX in a Power BI workspace in your browser. Each of the three sections issues its own certificate for LinkedIn or your CV. It is Coddy's certificate of completion, not Microsoft's PL-300 exam; the DAX is the same.
Inside the journey
Each section below issues its own certificate when completed. Browse the full journey to see every lesson and challenge.
01
Power BI BasicsYour first week as the analyst of a coffee chain: tables and fields, your first charts and slicers, DAX measures, why one measure gives a different answer in every bar, and calculated columns.
02
DAX with CALCULATEChange what a measure counts with CALCULATE: add filters, remove them for a percent of total, keep the ones a visual sets. Then work row by row with SUMX, FILTER and RANKX, and write DAX you can read with variables and SWITCH.
03
Time IntelligenceAnswer questions about time: the date table, revenue per day, year to date and running totals, the same period last year, growth from one period to the next, and moving windows like the last 7 days.

Are Coddy certifications really free?
Yes. Every certificate on Coddy is 100% free to earn, view, download, and share. There is no hidden paywall or subscription required to receive your certificate.
Why should you get a Coddy certification?

How can someone verify my certificate?
Every certificate has a unique ID and a public URL. Anyone, including recruiters and employers, can paste the ID into the verification tool on this page, or open the URL directly, to confirm the certificate is genuine and see the details.
Can it be showcased on LinkedIn or an other platform?
Of course, it's easy! You are provided with a URL link, PDF format and a certification ID, you can share any of those to showcase your active certification.
How long does it take to earn one certificate?
It depends on the section and your pace. Most sections take a few hours of focused practice spread over a few days. Coddy is built around short, daily sessions, so you can fit it around school or work.
Can I earn multiple certificates?
