Types of Engineering Certifications

Engineering certifications range from state-issued licenses like the Professional Engineer (PE) to professional credentials in project management, quality, safety, and software. This guide covers the certifications engineers and employers ask about most — what each one proves, how to earn it, and which careers it advances.

Licensure

• Fundamentals of Engineering / Engineer in Training (FE / EIT) — issued by NCEES (state licensing boards). The first step toward a PE license. Passing the FE exam earns the Engineer in Training (EIT) or Engineer Intern (EI) designation, showing an employer you're on the licensure track. How to earn it: Graduation from (or final year of) an ABET-accredited engineering program, then a 110-question computer-based exam in your discipline. Best for: Recent graduates, Civil engineers, Mechanical engineers, Anyone pursuing a PE.
• Professional Engineer License (PE) — issued by State licensing boards (NCEES exams). The full engineering license — legally required to sign and seal engineering drawings, offer services to the public, and use the title 'engineer' in many states. The single most valuable credential in civil, structural, and MEP work. How to earn it: ABET-accredited degree, passing the FE exam, typically 4 years of progressive experience under a licensed PE, and passing the PE exam in your discipline. Best for: Civil engineers, Structural engineers, Electrical (power) engineers, Mechanical/HVAC engineers, Consulting firm engineers.
• Structural Engineer License (SE) — issued by State licensing boards (NCEES exam). A separate, more rigorous license beyond the PE, required in some states (like Illinois and Hawaii) and for certain high-risk structures — hospitals, schools, and high-rises — especially in seismic states. How to earn it: PE-level qualifications plus the 16-hour NCEES SE exam. Several western states require it for designated essential facilities. Best for: Structural engineers, Bridge engineers, Seismic design specialists.

Frequently Asked Questions

What's the difference between a license and a certification?

A license (like the PE) is issued by a state government and is legally required for certain work — only licensed engineers can sign and seal drawings. A certification (like PMP or CQE) is issued by a professional organization and demonstrates expertise, but isn't legally required. Licenses are mandatory for specific work; certifications are competitive advantages.

Which engineering certification is most valuable?

For civil, structural, and MEP engineers, the PE license is by far the most valuable — it's often required for advancement past mid-level. In manufacturing and quality, Six Sigma Black Belt and CQE lead. In software and infrastructure roles, cloud certifications (AWS/Azure) and Kubernetes credentials carry the most weight with employers.

Do software engineers need certifications?

Rarely as a hard requirement — demonstrated skill, projects, and experience matter more. Exceptions: cloud and Kubernetes certifications genuinely help for DevOps and platform roles, and CISSP is often required in defense, finance, and government security work.

How long does it take to get a PE license?

Typically about 8 years from starting college: a 4-year ABET-accredited degree, the FE exam (often taken senior year), 4 years of progressive experience under a licensed PE, then the PE exam. Some states allow taking the PE exam early, but the license is still issued only after the experience requirement is met.

Will employers pay for certifications?

Very often, yes. Most engineering firms cover PE exam fees and review courses, and many manufacturers fund Six Sigma and ASQ certifications. Tuition and certification reimbursement is a common benefit — ask during the offer stage.
