Engineering certifications and licenses, explained.
The credentials that matter in US engineering — P.E., SE, LEED AP, PMP, ENV SP, NCEES Record — and how to verify them before contract.
Every credential that matters when hiring an engineer.
The engineering profession blends legally-required licensure (the P.E.) with voluntary industry certifications (LEED AP, PMP, ENV SP, Six Sigma, ASHRAE). Knowing which credentials apply to your scope — and how to verify them — is the difference between a sealed deliverable and a wasted RFP cycle.
VectorCore consolidates both license and certification data on every engineer profile. P.E. records sync live from state boards. Certifications are claimable by the engineer and verifiable against the issuing organization.
Below is the live roster of credentialed engineers in the US directory. Filter by state, discipline, or certification to find a qualified practitioner for your scope.

Frequently asked questions
What engineering certifications matter most?+
The P.E. (Professional Engineer) license is the primary legal credential for practicing engineering in the US. Beyond that, common certifications include SE (Structural Engineer), LEED AP, PMP, ENV SP, ASHRAE BEAP, Six Sigma Black Belt, and discipline-specific NCEES records.
What's the difference between a license and a certification?+
A license (like the P.E.) is a legal credential issued by a state board and required to perform certain engineering work. A certification (like LEED AP or PMP) is a voluntary credential issued by a professional body that demonstrates expertise but is not a legal requirement.
Is a P.E. license a certification?+
Technically, the P.E. is a license, not a certification — it is issued by a state government and carries legal authority. Industry credentials like LEED AP, PMP, or Six Sigma are certifications offered by professional organizations.
What is the NCEES Record?+
The NCEES Record is a centralized credential file maintained by the National Council of Examiners for Engineering and Surveying. It streamlines applying for P.E. licensure in additional states by holding verified education, exam, and experience records.
How do I verify an engineering certification?+
License credentials (like the P.E.) are public record on each state board. Industry certifications (LEED AP, PMP, etc.) can be verified through the issuing organization's online directory. VectorCore profiles consolidate both into a single view.
