CompTIA Data+ Practice Test

The CompTIA Data+ Practice Test is a free intermediate-level, 20-minute skill test from Science of Apps. It tests readiness for the CompTIA Data+ (DA0-002) exam — data concepts, structures and sources, acquiring and preparing data with SQL and cleaning techniques, statistical analysis, visualisation and reporting, and data governance, quality and privacy. Score 70% or more on its 20 questions to earn a verifiable Data+ Exam Readiness certificate (SOA-DTPL). Every question is based on published standards and research — including CompTIA Data+ (DA0-002) exam objectives (CompTIA), DAMA-DMBOK: Data Management Body of Knowledge (DAMA International), Visual Vocabulary (Financial Times) — and each answer is explained with its source.

Read the four skill areas on this page, then take the 20-minute test online — no fee, course or sign-up. You see every answer explained when you finish. Score 70% or more and you get a Data+ Exam Readiness certificate straight away, on screen, as a PDF and by email, with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: CompTIA Data+ (DA0-002) exam objectives (CompTIA); DAMA-DMBOK: Data Management Body of Knowledge (DAMA International); Visual Vocabulary (Financial Times); Introductory Statistics 2e (OpenStax (Rice University)); Dimensional modeling techniques (Kimball Group); MySQL 8.4 Reference Manual (Oracle). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Data Concepts and Acquisition (Data types and structures, Sources and storage and SQL basics); Data Preparation and Analysis (Cleaning, Transformation and Statistics); Visualisation and Reporting (Chart choice, Dashboards and Communication); Data Governance and Quality (Quality dimensions, Privacy and security and Stewardship). Every question is an original scenario based on a published standard, official documentation or research, named under the question.
