The short version
Databricks requires no prerequisite for this exam, but it highly recommends relevant training and about one year of hands-on experience with the tasks in the exam guide. In our view, working knowledge of Python and of libraries such as scikit-learn, SparkML, and MLflow also helps. If you are missing more than a few items on the checklist below, build those skills first.
Required versus recommended
| Type | What Databricks says |
|---|---|
| Required | Nothing. No prerequisite exam or course. |
| Highly recommended | Course attendance and about 1 year of hands-on Databricks experience |
| Recommended courses | Machine Learning at Scale; Advanced Machine Learning Operations (instructor-led or self-paced in Databricks Academy) |
| Our suggestion (not a vendor list) | Working knowledge of Python and ML libraries such as scikit-learn, SparkML, and MLflow, and of Lakehouse Monitoring and Databricks Model Serving |
Databricks does not say that you must hold another Databricks certification first. The associate-level machine learning exam is a separate credential, and the pages we read do not list it as a requirement. If you are new to Databricks machine learning, it can still be a useful stepping stone, but that is our suggestion, not a vendor rule.
What to know before you start
Python and machine learning basics. You should read Python comfortably, because questions show code and API calls. You should know how to train, tune, and evaluate a model, and what leakage, overfitting, and drift mean.
Spark. Understand DataFrames, how work is distributed across executors, and what is held in memory on one worker. Many scaling questions turn on that.
MLflow. Know tracking, runs, parameters, metrics, artifacts, model signatures, and the model registry in Unity Catalog.
Databricks platform. Notebooks, jobs, clusters and compute, Unity Catalog, and the Databricks CLI.
Software engineering habits. Version control, testing, and continuous integration are part of the MLOps domain, so ideas such as unit tests and environment promotion should not be new.
Skills self-check
Tick the items you can do or explain without looking anything up.
- Build a SparkML pipeline with indexing, encoding, vector assembly, and an estimator, then tune it with cross-validation.
- Explain when SparkML is a good fit and when a single-node model is simpler.
- Train a model per group with a pandas Function API, and say what limits group size.
- Describe how Optuna and Ray each distribute tuning, and log the results to MLflow.
- Use nested runs, and log custom metrics and artifacts.
- Explain point-in-time correctness and why it prevents leakage.
- Describe the difference between offline features, online tables, and on-demand features.
- Explain the deploy-code approach to moving work between dev, test, and prod.
- Describe which tests (unit, integration) belong at which stage.
- Define a job, an experiment, a registered model, and a serving endpoint in a Databricks Asset Bundle.
- Name the three table types a Lakehouse Monitoring monitor can profile, and say when each fits.
- Explain how drift is detected against a baseline and between consecutive windows.
- Describe blue-green and canary rollouts and when each makes sense.
- Log a custom PyFunc model with an artifact and query it through REST or the MLflow Deployments SDK.
Ten or more ticks means you are close. Five or fewer means a month of hands-on work will pay off more than extra reading.
Ways to fill gaps
- Take the courses Databricks recommends in Databricks Academy, and read the matching documentation.
- Build a small end-to-end project: features, training, tracking, a bundle, a monitor, and a serving endpoint.
- Use the skill list in the exam guide as a checklist, and write one sentence per bullet in your own words.
- Run a practice set early to find which domain needs the most work. Our study plan shows where this fits.

Frequently asked questions
Do I need the associate exam first?
No. The Databricks pages we read list no required prerequisite.
Can I take the exam without Databricks experience?
It is allowed, but Databricks highly recommends about a year of hands-on experience, and the questions assume it.
