The PL-300 (Microsoft Certified: Power BI Data Analyst Associate) is the main Microsoft certification for Power BI. It replaced the older DA-100 exam, covers the same broad territory, and is achievable for anyone with three to six months of regular Power BI use. Whether it is worth your time depends on what you are trying to prove, and to whom.
What PL-300 actually covers
The exam is split into four domains, with the weighting changing slightly every couple of years. As of 2026:
Prepare the data (25–30%). Connecting to sources, profiling data quality, cleaning and shaping in Power Query (M). Expect questions on dataflows, parameters, and folding.
Model the data (25–30%). Building star schemas, defining relationships, configuring filter direction, writing DAX measures and calculated columns, designing date tables, applying row-level security. The largest topic by weighting and the one most candidates underestimate.
Visualise and analyse the data (25–30%). Choosing appropriate visuals, formatting reports, accessibility considerations, AI visuals, paginated reports basics, and the bookmark / drill-through / tooltip patterns.
Deploy and maintain assets (10–20%).Workspaces, apps, sharing, sensitivity labels, scheduled refresh, deployment pipelines (dev / test / prod), and the admin features a regular user might touch.
Format, cost and pass mark
The exam is 40–60 questions delivered over 100 minutes, sat either in a test centre or online with Pearson VUE proctoring. The pass mark is 700 out of 1000 — note that questions are scored differently, so this is not a straightforward 70%. The UK exam fee is £113 plus VAT (so £135.60) as of 2026. Microsoft regularly runs offers — Cloud Skills Challenges and conference attendees often get a free voucher worth keeping an eye out for.
Results are immediate at the end of the exam, with a domain breakdown showing which areas you were strong or weak on. A retake is possible after a 24-hour cooling-off period, and you can sit the exam up to five times in a 12-month period.
A realistic study plan
For someone with some prior Power BI experience and 5–7 hours a week of study time:
Weeks 1–2: Microsoft Learn PL-300 path, modules 1–4. Build a small Power BI report on a public dataset (Premier League results, UK road accidents, anything with both dates and dimensions). The point is to do, not just read.
Weeks 3–4: DAX fundamentals via SQLBI's free "Introducing DAX" video course or "DAX in a Day". Focus on time intelligence, CALCULATE and filter context — these appear in almost every exam.
Week 5: Row-level security, workspaces, sharing, deployment pipelines. Hands-on practice in a free Power BI tenant. If your employer's tenant is locked down, sign up for a free 60-day Pro trial in your own name.
Week 6: Practice exams. The official MeasureUp PL-300 practice tests cost about £80 and are the closest to the real thing. Several free practice question sets exist on YouTube and Whizlabs, of variable quality — treat them as supplements, not as your main preparation.
Week 7: Targeted revision on weak domains identified from practice exams, then sit the real exam.
Is PL-300 worth it?
Three honest answers depending on the situation.
If you are job-hunting in BI or analytics: yes. Recruiters filter on it, even when hiring managers do not particularly care. Costs you a few weekends and £135 and clears an artificial bar.
If you are an internal team building reports for your own business: probably not. Nobody who matters will check, and the time is better spent building actual production reports and learning DAX properly.
If you are a consultant or freelancer: a soft yes. It does not win you work on its own, but the absence of it occasionally costs you a procurement tick-box. We treat ours as housekeeping that needs renewing every couple of years.
What PL-300 does not prove
Worth being honest. PL-300 proves you understand the platform's surface area and can answer multiple-choice questions on it. It does not prove you can:
Design a maintainable semantic model for a complex business domain. Write efficient DAX that performs on tens of millions of rows. Decide whether DirectQuery, import, or DirectLake is right for a given situation. Have a useful conversation with a finance director about why their numbers do not match the source system.
Those are the things consulting clients actually pay for, and they come from doing the work, not from passing an exam.
Renewal
PL-300 is valid for 12 months. Microsoft now uses a free annual online renewal assessment rather than re-sitting the full exam, which is a sensible change. The renewal is 20–30 questions, takes about an hour, and is unproctored. As long as you are still using Power BI regularly, it is straightforward.

Frequently asked questions
How much does the PL-300 exam cost in the UK?
£113 plus VAT (£135.60) as of 2026, with regular discount vouchers available via Microsoft Cloud Skills Challenges and partner events.
How long does it take to prepare for PL-300?
Roughly 6–8 weeks of study at 5–7 hours per week for someone with prior Power BI experience. Longer from a cold start.
Is PL-300 enough to get a Power BI job?
It is often a filter recruiters use, so it helps you pass screening. It does not on its own demonstrate the skills employers actually need — a portfolio of real reports usually matters more in the final interview.
