How to Verify a CompTIA Linux+ Certification
CompTIA Linux+ validates foundational to intermediate Linux system administration skills, including scripting, security hardening, container management, and automation. It is a vendor-neutral Linux credential and part of CompTIA's CE (Continuing Education) program. Here is how to verify it.
Quick answer
Verify CompTIA Linux+ at verify.comptia.org. Enter the candidate's name and certification code or email to confirm active status. CompTIA Linux+ is a CE certification requiring 30 Continuing Education Units (CEUs) every 3 years to remain active.
What CompTIA Linux+ covers
The current Linux+ (XK0-005) exam covers:
- System management: installation, configuration, file systems, processes
- Security: permissions, SELinux, firewall configuration, cryptography
- Scripting and automation: Bash scripting, Git basics, infrastructure as code
- Troubleshooting: boot issues, network diagnostics, log analysis
- Containers and virtualization: Docker, Kubernetes basics, virtual machines
Linux+ is vendor-neutral and covers skills applicable to any Linux distribution (RHEL, Ubuntu, Debian, SUSE). It is distinct from distribution-specific certifications like RHCSA (Red Hat) or the Ubuntu Certified Professional.
How to verify via CompTIA
- Go to verify.comptia.org
- Enter the candidate's name and their CompTIA certification code (found on their certificate)
- Confirm the Linux+ certification is listed as Active
- Check the expiration date — CE certifications expire after 3 years without renewal
CompTIA also issues Credly digital badges for Linux+. Candidates can share a Credly badge link as an alternative verification method.
CE renewal requirements
CompTIA Linux+ is part of the CompTIA Continuing Education (CE) program:
- Requires 30 CEUs earned over a 3-year certification period
- CEUs can be earned through training, conference attendance, higher-level CompTIA exams, or other qualifying activities
- Alternatively, passing a higher-level CompTIA exam (e.g., CASP+) automatically renews lower-tier certifications
- Certifications that lapse due to non-renewal are no longer active — confirm active status at verify.comptia.org
Linux+ vs. distribution-specific Linux certifications
| Certification | Vendor | Scope |
|---|---|---|
| CompTIA Linux+ | CompTIA (vendor-neutral) | Foundational-intermediate; any distro; CE program |
| RHCSA (Red Hat Certified System Admin) | Red Hat | RHEL-specific; performance-based exam; no multiple choice |
| RHCE (Red Hat Certified Engineer) | Red Hat | Advanced RHEL; Ansible automation; requires RHCSA |
| LPI LPIC-1 / LPIC-2 | LPI (Linux Professional Institute) | Vendor-neutral; globally recognized; different exam body from CompTIA |
For roles requiring RHEL-specific expertise (e.g., enterprise Linux at banks or government agencies), the RHCSA/RHCE is typically preferred over Linux+. For general Linux admin roles without a specific distro requirement, Linux+ is a recognized credential.
DoD 8140 context
CompTIA Linux+ may appear in government contractor and DoD-adjacent roles. However, Linux+ is not currently listed in DoD 8140 (formerly 8570) approved baselines — unlike CompTIA Security+, CASP+, and CySA+ which are 8140-approved. Confirm whether the specific role requires a DoD 8140-approved certification before treating Linux+ as satisfying that requirement.
Verification checklist
- 1. Verify at verify.comptia.org using candidate name and certification code
- 2. Confirm Active status — not Expired due to CE non-renewal
- 3. Confirm the exam version (XK0-005 or later) is current for the role's technology stack
- 4. For RHEL-specific environments: verify whether RHCSA/RHCE is required instead
Verify IT program accreditation
Linux administrators often hold degrees from accredited computer science or information technology programs. Use VerifyED to confirm whether a school's program is properly accredited.
