The Databricks Certified Data Engineer Professional exam assesses your ability to perform advanced data engineering tasks on the platform. Where the Associate asks whether you can build a pipeline, this asks whether you can write the code, tune it for cost and performance, secure it, and debug it when it fails at scale.

There are no prerequisites and the Associate is not required. Databricks recommends one year of hands-on experience with the data engineering tasks in the exam guide.

The outline changed on 9 October 2026. Exams taken from that date follow a new nine-section outline with 60 scored questions; the old ten-section version ran until 8 October. The exam format page lists what moved.

What the exam covers

SectionWeight
Developing Code for Data Processing using Python and SQL23%
Cost & Performance Optimisation15%
Data Ingestion & Acquisition12%
Data Manipulation12%
Monitoring and Alerting10%
Debugging and Deploying10%
Ensuring Data Security and Compliance8%
Data Governance5%
Data Modelling5%

Nine sections, still the most granular structure of any exam covered here. Only one exceeds 15%, and three are 8% or less.

Two things follow. First, writing code is the centre of the exam: at 23%, Developing Code for Data Processing using Python and SQL is nearly a quarter of it and has no counterpart on the Associate. Second, nothing else is large enough to carry you, so breadth is mandatory and blind spots are expensive.

Note what grew relative to the Associate: cost and performance optimisation is a 15% section of its own, where the Associate bundles tuning into a 10% troubleshooting section. Ingestion drops from 21% to 12%, and at this level it includes CDC from relational databases, OpenSharing (formerly Delta Sharing), Clean Rooms and Lakehouse Federation rather than basic file loading.

Format at a glance

60 scored questions in 120 minutes, multiple choice, online or at a test centre. The fee is $200 and the credential is valid for two years.

Databricks’ exam page still lists English, Japanese, Portuguese (Brazil) and Korean, and does not say whether the new version is available in each of those yet. Check the language list when you book.

Where to start

Read the exam format, then how it differs from the Associate if you hold that credential. The study plan groups the nine sections into manageable blocks.
