CompTIA offers both Core certifications and Expansion Series certifications to help technology professionals develop and validate their skills. While both support career growth and professional development, they are designed for different purposes.
Core CompTIA Certifications
Core CompTIA certifications validate the broad knowledge and skills required for a specific job role or career pathway. These certifications establish foundational and intermediate competencies that professionals need to perform successfully in their roles.
Core certifications are designed to:
- Validate a wide range of job-role skills
- Establish foundational and career-level knowledge
- Support career entry and advancement
- Build long-term career pathways
Examples include:
- A+
- Network+
- Security+
- Linux+
- Cloud+
- Server+
- CySA+
- PenTest+
Expansion Series Certifications
Expansion Series certifications are designed to build upon existing knowledge and experience by focusing on specialized and emerging skill areas.
Rather than validating the full breadth of a job role, Expansion Series certifications concentrate on targeted skills related to specific technologies, tools, or industry trends.
Expansion Series certifications are designed to:
- Develop skills in emerging technologies
- Complement existing certifications and professional experience
- Focus on specialized areas of expertise
- Help professionals stay current as technology evolves
- Provide focused skill development without repeating knowledge already gained through broader certifications
Examples include:
- SecAI+
- AutoOps+
Additional Expansion Series certifications may be introduced as technology and workforce needs continue to evolve.

Which Option Is Right for Me?
Core certifications are typically the best choice for learners looking to build foundational skills, prepare for a specific IT or cybersecurity role, or establish a career pathway.
Expansion Series certifications are best suited for professionals who already have experience or certifications and want to develop expertise in newer or specialized areas of technology.
