The Certified Data Analytics Engineer (CDAE) is an advanced, vendor-neutral certification for the analysts who turn data into decisions. It validates that you can frame the right question and run the analytics lifecycle, prepare and clean data to a trustworthy state, apply statistics without falling into the classic traps, visualize honestly and design clear dashboards, communicate insight to any audience, and work within governance, privacy and ethics. The exam is computer adaptive and performance-based, and the credential is kept current through continuing education.
| Level | Advanced. A specialist credential: it goes deep on analyzing and communicating data and assumes working analytics or reporting experience. |
|---|---|
| Delivery model | Computer adaptive, three stages. Your score on each stage selects the difficulty of the next, so no two candidates sit the same paper. |
| Format | 120 questions. A performance-based exam that includes performance-based questions and multiple-choice questions. Concepts transfer across every tool and platform. |
| Time | 180 minutes for the whole exam, timed. Autosaves every answer. |
| Scoring | You need a score of 700 out of 900 to pass. Results are reported on a scale of 100 to 900, and 700 corresponds to answering 72% of the exam correctly. Harder questions carry more weight, so a score means the same thing on any route. Multiple-response items and PBQs are all or nothing. |
| Retakes | No waiting period after a failed first attempt. Every attempt is paid for at the exam price. See the CertLabz Certification Retake Policy. |
| Voucher validity | 12 months from purchase, for one sitting. |
| Certification validity | 3 years. Renew with 75 CEUs per cycle and the $55 annual CE fee, or pass the current exam. Renewal details. |

A signed, verifiable:
The CDAE is a performance-based exam: it includes performance-based questions alongside multiple-choice questions. Instead of only picking A, B, C or D, you match analytics types to the questions they answer, fix a misleading chart, order the data-preparation steps, and draw the sound conclusion from a statistic. It is computer adaptive, is proctored and timed, needs no mandatory course, and tests doing analytics rather than reciting definitions.
Framing the question, the analytics lifecycle, and cleaning and integrating data to a trustworthy state.
Central tendency and spread, correlation versus causation, p-values, sample size and sampling bias.
Choosing the right chart, avoiding misleading axes and chartjunk, and designing clear, focused dashboards.
Data storytelling for any audience, plus privacy, ethics and reproducible analytics operations.
Data analytics is one of the most in-demand skill sets across every sector, and analysts who can be trusted with the whole lifecycle move up fast. Every route is shown here at once, so nothing is hidden behind a control you have to find.

Every form is drawn from a bank of more than 150 items to these exact weights, whichever adaptive route you take. Filter by the area you want to study.
The exam runs in three stages. Your score on each stage selects the difficulty of the next, so a strong candidate is stretched and a struggling one is measured fairly rather than swamped. No two candidates sit the same paper. Harder questions carry more weight, so a scaled score means the same thing whichever route you took.
Each exam can have up to 5 to 12 performance-based questions, drawn fresh on every attempt, alongside the multiple-choice questions. A PBQ is a task rather than a list: you match analytics types to questions, fix a misleading chart, order preparation steps, or draw the sound conclusion. They are scored all or nothing, so partial guesses do not pass.
Yes. Concepts apply across spreadsheets, SQL, BI tools and notebooks. Where a question involves a technique, it is described generically, not by one product's menus.
No. The CDAE focuses on analytics reasoning, statistics, visualization and communication. Familiarity with a spreadsheet, SQL or a BI tool helps, but no specific language is required.
700 out of 900. Results are reported on a scale of 100 to 900, and 700 corresponds to answering 72% of the exam correctly.
