In the event that you fail your first attempt at passing the Linux+ examination, CompTIA's retake policies are:
- If a Candidate has passed an exam (or multiple exams) and achieved a certification, he/she cannot take the exam again, using the same exam code, without prior consent from CompTIA.
- CompTIA beta examinations may only be taken one time by each candidate.
- A test found to be in violation of the retake policy will be invalidated and the candidate may be subject to a suspension period. Repeat violators will be permanently banned from participation in the CompTIA Certification Program.
- Candidates must pay the exam price each time they attempt the exam. CompTIA does not offer any free re-tests or discounts on retakes.
CompTIA Linux+ certification expires after three years from the date of issue, after which the certification holder will need to renew their certification via CompTIA's Continuing Education Program.
