Exam General Guidelines
Juniper Networks upholds high standards for JNCP certifications by implementing recertification criteria to ensure certified professionals maintain relevant skills. These criteria apply across all JNCP certification tracks and may be updated as needed. To renew a certification, candidates must either pass an exam or complete a higher-level course within the same track. This renewal extends the validity of all lower-level active certifications within the track, as well as any other active Associate-level certifications. Certification holders can monitor their status through CertMetrics and receive periodic email notifications regarding their certification status. It is their responsibility to keep both their certifications and contact details up to date. All JNCP certifications remain valid for three years, after which they will expire if not renewed within the specified timeframe.
