- No verified pass rate has been published for Fundamentals of Electricity - AC/DC (FEAD); any specific percentage you see online is unsourced.
- The documented bar is at least 70% on each certification examination, plus separately completing the required hands-on labs.
- Training must come from an actively certified NC3 instructor at a properly equipped institution before you can sit the exam.
- Student recertification is not required; the 80% score and three-year renewal rules apply to instructors only.
Why There Is No Single Published Pass Rate
Search for the pass rate of Fundamentals of Electricity - AC/DC (FEAD) and you will find confident-sounding percentages on forums and aggregator sites. None of them trace back to a primary source. Festo Didactic, which issues the credential through the Festo Industry Certification Program (FICP), and the National Coalition of Certification Centers (NC3), which delivers examinations through NC3Certs at participating institutions, have not published a verified national pass rate for this credential in the materials we checked.
That absence is not unusual for school-delivered certifications. Exams are administered inside classrooms and labs at member institutions, under each school's proctoring rules, as part of a course sequence. Outcomes are tracked by instructors and programs, not released as a public leaderboard. For you as a candidate, the honest answer to "what is the pass rate?" is: no verified figure exists, so be skeptical of anyone who gives you one.
This article therefore does something more useful than repeating a number. It lays out what the data and policy documents actually establish, explains how the pass mechanics work, and shows you how to estimate your own likelihood of passing based on the real content. If you want broader context on difficulty, see our guide on how hard the FEAD exam is.
What the Issuer and NC3 Actually Publish
Here is what can be verified. The combined Level 1 Fundamentals of Electricity - AC/DC scope remains listed in NC3's FESTO Certification Portfolio (September 2026 file, revision 092326). Festo's current program page presents Fundamentals of Electricity as DC and AC preparation and links both component sheets. Those component documents list the Industry Recognized Certification Topics that preparation should cover:
- Fundamentals of Electricity - Direct Current (DC): document 272395 EN 2025.09, with 10 units and 10 labs.
- Fundamentals of Electricity - Alternating Current (AC): document 272396 EN 2025.09, with 6 units and 6 labs.
Neither sheet is a weighted exam blueprint. They are unweighted lists of certification preparation topics, and the 36 areas across both lists include intentional overlaps (Safety, Electricity Basics, Basic Electrical Wiring, and Troubleshooting each appear in both). They do not tell you how many questions each domain contributes, and they do not establish that every listed topic is tested. For the full topic breakdown, see our complete guide to all 36 FEAD content areas.
Equally important is what is not verified: the current number of exam questions, the length of an exam sitting, and student exam fees. The combined portfolio label does not establish whether candidates take one combined exam or separate DC and AC component exams. Any pass-rate analysis that quotes question counts or time limits is inventing them.
| Item | Status in primary sources |
|---|---|
| Published national pass rate | Not published / not verified |
| Minimum score to pass | At least 70% on each certification examination |
| Hands-on lab requirement | Required; separate from the knowledge assessment |
| Question count and timer | Not verified |
| Student exam fee | Not verified |
| Student recertification | Not required |
The Pass Mechanics: 70%, Labs, and Instructors
The policy that governs your result is the NC3Certs End User License Agreement. Its student terms establish several concrete conditions that shape what "passing" means:
- Qualified instruction first. Students must receive training from an actively certified NC3 instructor at a properly equipped institution.
- Hands-on labs are mandatory. You must complete the required labs. The knowledge assessment and the practical lab completion are separate requirements, so a strong written score does not substitute for unfinished labs.
- 70% per exam. You must score at least 70% on each certification examination.
- School proctoring. Exams follow the issuing school's proctoring rules.
- Account access. NC3Certs access requires an active email account for two-factor authentication.
For a deeper look at the threshold itself, read our explainer on the FEAD passing score, and for eligibility details see FEAD requirements and prerequisites.
Instructor rules are not student rules
A common source of confusion is renewal. NC3's agreement sets separate requirements for instructors: an 80% score and recertification every three years. Those do not apply to students; student recertification is not required. Meanwhile, the O*NET listing for the same combined credential (14512-A) flags continuing-education renewal. That secondary flag conflicts with the current primary NC3 student terms, so for student questions rely on the NC3 policy rather than the O*NET note. Misreading this distinction leads some candidates to overstate the ongoing burden of holding the credential.
What Scoring and Pass Outcomes Likely Depend On
Without published statistics, the useful question is what drives outcomes. Based on how the credential is structured, several factors matter more than any aggregate rate.
Lab completion is a gate, not a bonus
Because lab completion is a separate requirement from the written assessment, a candidate can fail to certify while knowing the theory perfectly well. The DC sheet is built around 10 labs and the AC sheet around 6. Those are curriculum quantities, not exam question counts or timed-exam lengths, but they signal how much of the credential rests on hands-on work: building circuits, taking measurements, and finding faults.
Your instructor and institution shape your preparation
Since training must come from an active NC3-certified instructor at a properly equipped institution, the quality of your lab access and instruction is a real variable. Candidates at well-equipped programs get repeated bench time with meters and breadboards. That experience matters for questions on reading instruments and interpreting measurements.
The historical guide points to applied competencies
The earlier combined-scope program guide (Festo, Level 1: Fundamentals - Electricity, March 2023, revision 031023) lists nine Industry Recognized Certification Topics. That count is an older, unweighted curriculum and not a verified current exam-section count. Still, its competencies are instructive: schematic reading, circuit construction, impedance and reactance calculations, practical measurements, and fault-finding. These applied skills, rather than rote memorization, are where preparation should concentrate. Our FEAD study guide builds a plan around exactly these competencies.
Where Candidates Tend to Lose Points by Domain
The sheets do not weight topics, so we cannot say which domain has the lowest correct-answer rate. What we can say is which topics are conceptually demanding and where calculation or interpretation errors typically occur in introductory electricity. Use these as a diagnostic, not as a statistical claim.
Ohm's Law and Kirchhoff's Laws (DC Domains 5-6; AC Domain 21)
These foundations recur across both components, so weakness here compounds everywhere.
- Rearranging V = I × R fluently for any unknown
- Applying Kirchhoff's voltage law around a loop with correct sign conventions
- Applying Kirchhoff's current law at a node with multiple branches
Series and Parallel Circuit Solving (DC Domain 8; AC Domain 23)
Combination circuits require reducing networks step by step.
- Equivalent resistance for series, parallel, and mixed networks
- Voltage division and current division reasoning
- Checking answers against power and conservation logic
Using Measuring Instruments (DC Domain 7; AC Domain 22)
Instrument questions test whether you know how a meter connects, not just what it measures.
- Voltmeters in parallel, ammeters in series
- Ohmmeters used only on de-energized circuits
- Interpreting readings that reveal opens, shorts, and high-resistance faults
AC-Specific Components (AC Domains 29, 32-35)
The AC list adds topics with no DC counterpart: AC capacitors, inductors, transformers, contactors, circuit breakers, electrical panels, fuses, and distribution networks.
- Reactance and impedance behavior of inductors and capacitors
- Transformer turns-ratio relationships
- Roles of fuses and circuit breakers in protection
- How panels and distribution networks deliver power
Troubleshooting (DC Domain 18; AC Domains 26 and 36)
Troubleshooting appears in both lists and tends to integrate everything else.
- Isolating a fault using measurements rather than guessing
- Distinguishing open circuits from shorts by their symptoms
- Choosing a logical order of tests
Safety also appears in both component lists (Domains 1 and 19) and deserves disciplined attention; our FEAD cheat sheet summarizes the must-know facts for last-minute review.
Numbers People Misread as Pass-Rate Data
Several real numbers in the source documents get mistaken for performance statistics. Clearing these up protects you from bad inferences.
| Number | What it actually is | What it is NOT |
|---|---|---|
| 36 | Combined count of topics across the DC and AC lists, with intentional overlaps | A count of official exam domains or a question total |
| 70% | Minimum score required on each certification examination | An average or typical score |
| 80% | Instructor score requirement | A student requirement |
| 10 units / 10 labs (DC); 6 units / 6 labs (AC) | Curriculum quantities | Exam question counts, timer lengths, or course-hour totals |
| 9 | Topics in the older March 2023 combined guide | A verified current exam-section count |
| USD $500 | NC3's annual institutional LMS fee, waived for active member institutions | A student exam price |
That last row matters for cost planning. The $500 figure is paid by institutions, not students, and it is waived for active members. Because current student exam fees were not verified, check with your school before assuming any out-of-pocket amount; our FEAD certification cost breakdown explains what is and is not established.
Key Takeaway
Every figure attached to FEAD in the primary documents describes either a requirement (70%, labs), a curriculum size (units and labs), or an institutional fee. None describes how many candidates pass. If a source presents one of these as a pass rate, it is misusing the number.
Building Your Own Pass Probability Estimate
Since no population statistic exists, the most reliable approach is a personal readiness audit. Treat 70% as your minimum target on each assessment and aim comfortably above it so a few misses do not sink you.
- Split your domains into DC and AC. Mark each domain as strong, shaky, or untested. Pay special attention to the AC-only topics, since candidates who finish a DC-heavy course often underprepare for panels, fuses, and distribution networks.
- Score yourself per component. Take timed practice sets separately for DC-style and AC-style content. If you score below 70% on either, treat that component as unready regardless of your overall average.
- Confirm lab completion. Check with your instructor that every required lab is logged. This is independent of your written readiness.
- Test calculation and interpretation separately. Calculation errors (Ohm's law, impedance, reactance) and interpretation errors (reading a schematic, diagnosing a fault) have different fixes.
- Retest the weakest domains. Improvement should be visible in your practice results before you sit the real exam.
You can run realistic drills on the FEAD practice test site, which uses original questions written for this credential rather than any copied exam bank. Those drills give you a personal data point far more meaningful than a rumored national percentage.
Domain Sequencing for the Final Weeks
This is the one place we address scheduling, and it is tied directly to how the FEAD content builds on itself. The logic: foundations first, because Ohm's and Kirchhoff's laws feed every later topic; AC-specific components next, because they are the newest material for most DC-trained candidates; troubleshooting last, because it integrates everything.
Safety, basics, and the core laws
- Safety (Domains 1 and 19) and Electricity Basics (Domains 3 and 28)
- Ohm's Law and Kirchhoff's laws (Domains 5, 6, 21)
- Resistance concepts (Domain 17)
Circuit solving and instruments
- Series and parallel circuits (Domains 8 and 23)
- Measuring instruments and measurement equipment (Domains 7, 16, 22, 30)
- Basic electrical wiring (Domains 4 and 31)
Magnetism and DC components
- Magnetism and electromagnetism (Domains 11, 12, 24)
- DC capacitors, relays, motors, solenoids (Domains 9, 10, 13, 14)
- Component survey (Domains 15 and 27)
AC components, distribution, and troubleshooting
- AC capacitors, inductors, transformers, contactors, breakers (Domains 29 and 32)
- Panels, fuses, and distribution networks (Domains 25, 33, 34, 35)
- Troubleshooting (Domains 18, 26, 36) and timed review

Frequently Asked Questions
No verified national pass rate has been published by Festo Didactic, FICP, or NC3 in the materials checked. Exams are delivered through participating institutions, so outcomes are tracked locally. Treat any specific percentage without a named primary source as unreliable.
The NC3Certs student terms require at least 70% on each certification examination. Separately, you must complete the required hands-on labs. The 80% requirement in NC3's agreement applies to instructors, not students.
Current question counts and exam-sitting durations were not verified, and it is not established whether a single combined exam or separate DC and AC exams are delivered. Ask your instructor or institution for the format your program uses rather than relying on unsourced figures.
No. Student recertification is not required under the current NC3 terms. Recertification every three years applies to instructors. An O*NET listing flags continuing-education renewal, but that secondary note conflicts with the primary NC3 student policy, which governs.
Not under the documented terms. Students must receive training from an actively certified NC3 instructor at a properly equipped institution and complete the required labs. See our overview of FEAD training and the FEAD exam dates guide for how scheduling typically works through your school.
The takeaway is simple: stop chasing a pass-rate number that does not exist and measure your own readiness against the 70% bar, the required labs, and the DC and AC topic lists. For a structured way to do that, start with our FEAD practice tests and use the results to decide where your next study hours should go.
