Exam General Guidelines
To maintain the high standards of JNCP certifications and ensure the ongoing relevance of certified individuals’ skills, Juniper Networks has established recertification criteria. These criteria are applicable across all JNCP certification tracks and are subject to potential revisions.
- Renewing certifications can be achieved by either passing an exam or completing a course at a higher level within the same track. This renewal also extends to all lower-level active certifications within the track, as well as any other active Associate-level certifications.
- Program participants have access to their certification status through CertMetrics and will receive periodic email notifications concerning their certifications. It is the responsibility of certification holders to keep both their certifications and contact information current.
- All JNCP certifications remain active for three years. Failure to renew certifications within this three-year period will result in their expiration.
