CompTIA Data+

CompTIA Data+ (DA0-002) is an early-career, vendor-neutral certification that validates the skills needed to analyze, interpret, and communicate data insights for informed business decision-making. It covers the full data analytics lifecycle from acquisition and preparation through analysis, visualization, and governance.

Version 2 expands coverage to include AI concepts, cloud data environments, and emerging compliance frameworks. Data+ is ideal for aspiring data analysts, business intelligence specialists, and professionals transitioning into analytics roles. It maps to the NICE Framework Data Analyst work role (IO-WRL-001).

The exam consists of up to 90 questions to be completed in 90 minutes. Question types include multiple-choice, multiple-response, and performance-based questions (PBQs) that simulate real-world data analysis scenarios. PBQs may involve interpreting datasets, selecting appropriate visualizations, or identifying data quality issues. The passing score is 675 on a scale of 100-900. Experienced test-takers recommend answering multiple-choice questions first and returning to PBQs, as they typically require more time.

Candidates commonly underperform in several predictable areas. Weak statistical foundations trip up many test-takers — understanding when to apply mean vs. median, correlation vs. causation, and basic hypothesis testing is essential. The Visualization and Reporting domain (20%) catches candidates off guard because it requires practical knowledge of chart selection, dashboard design, and BI tool concepts. Data Governance (14%) is often deprioritized despite covering compliance, privacy, and quality assurance topics that appear throughout the exam. Finally, performance-based questions require applied thinking rather than memorization, so candidates who rely solely on flashcards tend to struggle.

CompTIA Data+ is delivered through Pearson VUE at authorized testing centers or via online proctoring. The exam costs $255 USD ($304 with retake assurance bundle). There is no wait period before a second attempt, but subsequent retakes require a 14-day waiting period. The certification is valid for 3 years from the date earned. Renewal requires completing 20 Continuing Education Units (CEUs) within the 3-year cycle, with a 30-day grace period for final submissions. An annual CE fee applies. Alternatively, passing a higher-level CompTIA certification automatically renews Data+.
