The DY0-001 exam is the official CompTIA exam behind CompTIA DataAI Certification — passing it earns you the CompTIA Data+ certification, a credential positioned at the Expert level. It is built for candidates who want to validate the skills measured by CompTIA DataAI Certification. Depending on your track, the exam is also linked to the CompTIA DataAI (formerly DataX) certification, so one pass can move you toward more than one CompTIA credential.
The DY0-001 exam presents Up to 90 questions to be completed within 165 minutes. That pace leaves little room for second-guessing: read each question carefully on the first pass, flag the ones you want to revisit, and keep moving instead of stalling on a single item. Before exam day, run at least one full timed session in the TestSimulate desktop or online test engine with a comparable question load — a steady rhythm under the clock is a trainable skill, and it is often what separates a pass from a near miss.
To pass the DY0-001 exam you need Pass/Fail (No scaled score), and the official registration fee is $529 USD. Keep in mind that a failed attempt means paying that fee again in full — retakes are not discounted. Given the cost, self-test before you book: if you can score comfortably above the passing mark on two or three consecutive timed TestSimulate practice tests, your budget is far better spent on the exam itself than on a retake.
5+ years of experience in data science or a similar role recommended. Because CompTIA revises its certification programs from time to time, treat this as a starting point rather than the final word. Confirm the current eligibility requirements on the official CompTIA exam page before you register.
Yes. A free PDF demo of the DY0-001 practice questions is available, so you can check the question style and answer quality before spending anything.
