What PL-300 tests
Microsoft’s study guide lists four skill areas, with these weights as of 20 April 2026:
| Skill area | Weight | What it includes |
|---|---|---|
| Prepare the data | 25–30% | Getting data from sources, cleaning and transforming it with Power Query, checking data quality |
| Model the data | 25–30% | Designing tables and relationships, writing DAX measures, improving model performance |
| Visualize and analyze the data | 25–30% | Building report pages and visuals, adding interactivity, finding patterns and trends |
| Manage and secure Power BI | 15–20% | Workspaces, sharing, refresh, and row-level security |
Microsoft also says candidates should be proficient with Power Query and DAX. In practice, those two skills support almost every question.
How to prepare for PL-300, step by step
- Read the official study guide. Turn each listed skill into a checklist and mark what you already know. Ready when you know exactly which skills are your weak spots.
- Install Power BI Desktop and practise daily. Power BI Desktop is free from Microsoft (Power BI Desktop). Ready when you are comfortable moving between Power Query, the model view and report view.
- Master Power Query. Merging and appending queries, unpivoting, data types and handling errors (What is Power Query?). Ready when you can clean a messy dataset without notes.
- Learn data modelling. Star schema, relationships, cardinality and a proper date table (Star schema guidance). Ready when you can explain why your model is designed the way it is.
- Practise DAX. CALCULATE, filter context, time intelligence and the difference between measures and calculated columns (DAX reference). Ready when you can write year-to-date and year-over-year measures from memory.
- Build and share reports. Publish to the Power BI service, set up workspaces, scheduled refresh and row-level security (Row-level security). Ready when you have done each task at least once yourself.
- Take Microsoft’s practice assessment. Use the official practice assessment linked from the certification page, which shows the style and difficulty of exam questions, then revise your weakest area. Ready when you score well consistently and understand why each wrong answer was wrong.
Is the PL-300 certification worth it?
It is worth it if you want a recognised, structured target and a credential that matches the skills Microsoft defines for a Power BI data analyst. It is especially useful for freshers and career switchers who have no work experience to show yet.
It is not a substitute for projects. Employers still want to see dashboards you built and hear you explain your choices. The strongest profile combines PL-300 with two or three finished projects and solid SQL. See Power BI jobs in Bangalore for the roles and interview questions to prepare for.
Common mistakes
- Memorising answers instead of practising. The exam can include interactive tasks that test whether you can actually do the work.
- Skipping the “manage and secure” area. It carries 15–20% and is often neglected by people who only build reports locally.
- Weak DAX fundamentals. Filter context questions catch out many candidates.
- Forgetting to renew. Set a reminder; renewal is free but must be done every 12 months.
