Hiring Guide - Certifications
What Engineering Certifications Actually Prove (And What They Don't)
NETA, NFPA 70E, PE, PMP, CxA, and ISA-CAP get treated as interchangeable resume badges. They're not, and knowing the difference changes how you should screen candidates.

A certification answers one specific question, not 'is this person good'
Every certification in this guide verifies a specific, bounded thing - a body of knowledge passed on an exam, a scope of practical testing competence, a legal standing to stamp drawings. None of them verify judgment, communication, or fit for your specific project, which is why a certification should inform your screening process rather than substitute for it.
| Certification | What it verifies | What it does not verify |
|---|---|---|
| PE (Professional Engineer) | Legal authority to stamp/seal engineering documents; passed rigorous state licensing exams | Field judgment, ability to manage a project or team |
| NETA Certification | Competence in electrical testing procedures for power system equipment | Design capability or broader electrical engineering scope |
| NFPA 70E | Training in electrical safety work practices and arc flash hazard awareness | General electrical competence beyond the safety scope |
| PMP (Project Management Professional) | Familiarity with formal project management methodology and terminology | Actual leadership skill or technical domain knowledge |
| CxA (Certified Commissioning Authority) | Recognized competence in commissioning process management | Hands-on technical troubleshooting skill on specific equipment |
| ISA-CAP (Certified Automation Professional) | Broad knowledge of automation, control systems, and instrumentation concepts | Hands-on fluency with a specific PLC or SCADA platform |
How to actually use certifications in screening
PE - necessary but not sufficient for design authority roles
A PE is often a hard legal requirement for roles that involve stamping drawings, so its absence can be an automatic disqualifier for those specific roles. But it says nothing about whether the engineer communicates well, manages ambiguity, or has relevant sector experience - those still need to be evaluated directly.
NETA and NFPA 70E - verify safety and testing competence, not seniority
These are frequently confused with broader electrical engineering seniority, but they verify a specific, narrower competence: safe and correct execution of testing and field work. A candidate can hold both and still lack the design or troubleshooting judgment a senior electrical engineering role requires.
PMP - evaluate the person, not the badge
PMP certification demonstrates exposure to formal project management frameworks, which is genuinely useful vocabulary and structure. It is a weak predictor of whether someone can actually hold a room, manage a difficult stakeholder, or make a good call under schedule pressure - those require behavioral interview questions, not a certification check.
CxA and ISA-CAP - good screening signal, weak substitute for hands-on verification
Both certifications indicate a real investment in the discipline and a baseline of process knowledge. Neither substitutes for asking a candidate to walk through a specific past project in technical detail, which is the only way to verify hands-on competence rather than certified knowledge of the concepts.
A quick decision framework
- Is the certification a legal or regulatory requirement for this specific role? If yes, treat it as a hard screen.
- Does it verify a narrow technical or safety competence relevant to daily work? Weight it meaningfully but pair it with a technical interview.
- Does it verify process knowledge or methodology (PMP, CxA) rather than hands-on skill? Treat it as a positive signal, not a substitute for behavioral or technical evaluation.
- Always ask for a specific project example tied to the certified competence, regardless of which category it falls into.

Summary
Key takeaways
- Each certification verifies a specific, bounded competence - none of them substitute for evaluating judgment or fit directly
- PE is often a legal requirement for design-authority roles, but says nothing about communication or project management ability
- NETA and NFPA 70E verify safety and testing competence, not overall electrical engineering seniority
- PMP, CxA, and ISA-CAP indicate process knowledge investment but should be paired with a specific project walkthrough to verify hands-on skill
