Informations sur l'examen du cours
- CompTIA
Data+ is an entry- to early-career certification designed for professionals who
are beginning their journey in data analytics or looking to validate
foundational data skills. The certification demonstrates a candidate’s ability
to mine, analyze, and interpret data to inform business decision-making.
CompTIA Data+ emphasizes understanding data concepts, different data
environments, data collection and mining techniques, data visualization, basic
statistical methods, and data governance. The certification ensures that
professionals can effectively translate business requirements into actionable
insights and meaningful analyses. Being vendor-neutral, Data+ equips candidates
with transferable skills suitable for roles such as junior data analysts,
business intelligence specialists, reporting analysts, or any position that
requires working with structured and semi-structured data.
- Eligibility
/ Prerequisites:
While there are no mandatory prerequisites to take the Data+ exam, CompTIA recommends that candidates have approximately 18–24 months of experience in a reporting or business analyst role. Exposure to databases, data manipulation tools, analytical platforms, basic statistics, and visualization techniques is highly beneficial. This prior experience helps candidates grasp exam concepts more effectively. However, motivated newcomers to data analytics can also pursue Data+ successfully by combining study materials, hands-on practice, and exam preparation courses. The certification is designed to be accessible yet challenging enough to establish a solid data foundation.
- Exam
Structure:
The CompTIA Data+ certification is assessed through a single exam, DA0-001, which consists of up to 90 questions, including multiple-choice questions and a limited number of performance-based items (simulated, interactive scenarios). Candidates have 90 minutes to complete the exam. The passing score is 675 on a scale of 100–900. The exam covers five main domains:
- Data Concepts – foundational understanding of types of data, data structures, and the role of data in business.
- Data Environments – exposure to relational and non-relational databases, cloud and on-premises data storage, and data lifecycle management.
- Data Mining – techniques for collecting, cleaning, transforming, and profiling data to prepare it for analysis.
- Data Analysis and Visualization – applying descriptive statistics, summarizing data insights, creating dashboards, and interpreting results to inform decisions.
- Data Governance – understanding policies, procedures, compliance, data quality, and security standards that ensure reliable and ethical data usage.
- Renewal
/ Recertification:
The CompTIA Data+ certification is valid for three years from the date of issue. To maintain the credential, certified professionals must earn 20 Continuing Education Units (CEUs) over the three-year period or recertify through other qualifying CompTIA activities, such as completing a higher-tier certification or participating in relevant training programs. Data+ can automatically renew related lower-tier certifications like ITF+, if held. Failure to complete the renewal process results in expiration, as the certification is part of CompTIA’s Continuing Education Program, which encourages ongoing learning and skills maintenance.
- Additional
Notes:
Data+ not only validates technical data skills but also prepares candidates to communicate insights effectively to business stakeholders, ensuring that data-driven decision-making is accurate, actionable, and aligned with organizational goals. Its vendor-neutral approach makes it a flexible foundation for further certifications in analytics, data science, or business intelligence.
