Before you start

It helps to have used spreadsheets, a database or a reporting tool, and to know basic maths such as averages and percentages. CompTIA suggests 18 to 24 months in a data analyst or similar role, plus some exposure to databases, analysis tools, basic statistics and data visualisation, before you sit the exam.

About the DA0-001 exam

DA0-001 is an exam for the CompTIA Data+ certification. CompTIA is a global, vendor-neutral IT certification body. Data+ shows that you can collect, analyse and explain data in a way that helps a business make decisions. It covers data concepts, data mining, analysis, visualisation and governance. CompTIA launched a newer Data+ exam, DA0-002, in October 2025, so check which version you can book on the CompTIA website before you schedule. The core skills taught here still apply to both.
