The official exam objectives, rigorously developed with industry subject matter experts, are mapped directly to the critical functions of an early-career data analyst.
1. Data Acquisition and Preparation: The 'Cleaning Crew' Foundation (22% of Exam)
What you learn: This domain focuses on the crucial, often-overlooked first steps: sourcing, cleaning, and structuring raw data. You master the process of Extracting, Transforming, and Loading data (ETL/ELT), along with techniques for data profiling, handling missing values, and addressing data redundancy.
What you’ll actually do: You will spend a significant portion of your day manipulating data using tools like SQL and scripting languages like Python or R. Your task won't be simply pulling a report; it will be diagnosing why a critical column has inconsistent formats or why 30% of customer records are incomplete. You’ll be the gatekeeper ensuring data quality the single source of truth before any analysis even begins.
- Key Takeaway: The ability to clean, profile, and shape a messy dataset is arguably the most valuable skill for an early-career analyst, directly translating to Data Quality and trustworthy analysis.
2. Data Analysis: From Raw Numbers to Business Insights (24% of Exam)
What you learn: This core domain covers the application of basic statistical methods, hypothesis testing, and exploratory data analysis (EDA). It ensures you can apply analytical techniques to uncover trends, measure performance, and identify correlations.
What you’ll actually do: You will be asked business questions like, "What factors are driving our customer churn rate?" or "Has the new marketing campaign led to statistically significant sales growth?" You won’t just run a calculation; you’ll determine the appropriate type of analysis (e.g., trend analysis, correlation) and interpret the results to provide an actionable business insight. This involves going beyond simple averages and applying descriptive and inferential statistics to inform strategy.
3. Visualization and Reporting: Telling the Data Story (20% of Exam)
What you learn: The exam covers the principles of effective data storytelling, dashboard design, and the use of industry-standard visualization tools (like Tableau or Power BI). This is where you transform complex data findings into clear, compelling narratives for stakeholders.
What you’ll actually do: Data only has value when it can be understood. You will design and deploy dashboards and reports that track Key Performance Indicators (KPIs). You’ll choose the right chart not just the prettiest one to present an argument. For instance, you’ll use a time-series line chart to show a trend analysis to an executive team, ensuring the visual presentation supports the underlying data narrative and makes the findings immediately clear.
4. Data Concepts and Environments: Navigating the Data Landscape (20% of Exam)
What you learn: This domain provides the foundational context, covering different data types (structured vs. unstructured), file formats (JSON, XML, CSV), and data architecture concepts (data warehouses, data lakes, OLAP/OLTP). The newer version of CompTIA Data+ DA0-002 also begins to introduce modern topics like cloud data systems and AI concepts.
What you’ll actually do: You’ll be expected to know where to find the data and how to access it. This includes understanding schemas, querying relational and non-relational databases, and knowing the difference between static and continuous data feeds. When a manager asks for sales data, you’ll know where to find it. It may be in the OLAP data warehouse or in a raw, unstructured data lake. This knowledge enables efficient data acquisition.
5. Data Governance: Security, Quality, and Compliance (14% of Exam)
What you learn: This critical domain covers data governance principles, master data management, security requirements, and regulatory controls (like GDPR or HIPAA).
What you’ll actually do: You’ll ensure compliance and data security are paramount. Your day-to-day may involve assisting with setting access permissions for sensitive PII (Personally Identifiable Information) or documenting data lineage to ensure auditability. This skill sets clear expectations for a Data+ certified professional. It shows you are aware of the ethical and legal responsibilities tied to data handling. These responsibilities are a non-negotiable requirement for employers.
