CompTIA A+ Certification Exam Objectives
Exam Number: 220-902

Introduction
In order to receive CompTIA A+ certification a candidate must pass two exams. The first exam is the
CompTIA A+ 220-902 Certification Exam. The CompTIA A+ 220-902 Certification Exam is the second
exam required in order for CompTIA A+ certification candidates to complete their certification.
The CompTIA A+ 220-902 examination measures necessary competencies for an entry-level IT
professional with the equivalent knowledge of at least 12 months of hands-on experience in the lab or field.
Successful candidates will have the knowledge required to: Assemble components based on customer requirements
 Install, configure and maintain devices, PCs and software for end users
 Understand the basics of networking and security/forensics
 Properly and safely diagnose, resolve and document common hardware and software issues
 Apply troubleshooting skills
 Provide appropriate customer support
 Understand the basics of virtualization, desktop imaging, and deployment.
CompTIA A+ is accredited by ANSI to show compliance with the ISO 17024 Standard and, as such,
undergoes regular reviews and updates to the exam objectives. The following CompTIA A+ 220-902
certification exam objectives result from subject matter expert workshops and industry-wide survey results
regarding the skills and knowledge required of an entry-level IT professional. The percentages in thisdocument represent the relative importance of the subject areas (domains) in the associated body ofknowledge, and together establish the foundation of an entry-level IT professional.
This examination blueprint includes domain weighting, test objectives, and example content. Example
topics and concepts are included to clarify the test objectives and should not be construed as acomprehensive listing of all the content of this examination.
Candidates are encouraged to use this document to guide their studies. The table below lists the domains
measured by this examination and the extent to which they are represented. The CompTIA A+ 220-902
certification exam is based on these objectives.
