Why BEE-AC Doesn't Publish a Public Pass Rate
Anyone searching for a headline "BEE-AC pass rate" number for Basic Electricity and Electronics - Alternating Current will run into a wall: CertTEC, the division of SpaceTEC Partners, Inc. that administers this certification, does not release aggregate pass/fail statistics to the public. That's a meaningful difference from certifications that publicize year-over-year pass rate charts. Instead of chasing a number that doesn't exist, the more useful exercise is understanding the mechanics that determine whether an individual candidate passes: the 70% passing score, the performance-based format, and the specific skills tested across the exam's 12 content domains.
This article walks through those mechanics in detail so you can gauge your own readiness rather than relying on a borrowed statistic from an unrelated program. If you've seen pass rate figures attached to "BEE-AC" elsewhere, be cautious - several credentials share this acronym, and figures belonging to a different program don't apply to Basic Electricity and Electronics - Alternating Current.
What the 70% Passing Score Actually Tells You
CertTEC sets the BEE-AC passing score at 70%. Because the exam is a performance assessment rather than a scored multiple-choice test, that 70% threshold reflects how many required tasks and measurement steps you complete correctly - instrument setup, waveform interpretation, transformer fault isolation, and RC/RL troubleshooting sequences among them. A candidate who can recite AC theory but fumbles the physical setup of a function generator or misreads an oscilloscope trace can lose points even with strong conceptual knowledge.
For a full breakdown of how the scoring threshold is applied and what "passing" looks like task by task, see BEE-AC Passing Score 2026: Exactly What You Need to Pass. Understanding the scoring mechanism is arguably more useful than any pass rate percentage, because it tells you exactly what to rehearse.
Key Takeaway
Treat the 70% passing score as your target, not a published pass rate. Every practice session should be measured against whether you can hit that threshold on hands-on tasks, not just recall facts.
How the Performance Assessment Format Shapes Results
BEE-AC is delivered as a proctored, in-person performance assessment through SPI's online Examination Management System. This format is a major reason a generic pass rate figure would be misleading even if one were published: outcomes depend heavily on physical dexterity with test equipment, not just written knowledge.
During the assessment, candidates work with:
- Two CertTEC assessment circuit cards per discipline
- A Nida 130E or later trainer
- A multimeter
- A function generator
- An oscilloscope
Candidates who have never physically handled this exact equipment combination - especially the Nida trainer paired with the CertTEC circuit cards - tend to struggle regardless of how well they understand AC theory on paper. If you're unsure how demanding this format is compared to written-only exams, How Hard Is the BEE-AC Exam? Complete Difficulty Guide 2026 breaks down the difficulty profile in more depth.
Domain 10: Test Equipment and Measurements
This domain is the practical backbone of the entire assessment because every other domain gets demonstrated through instrument readings.
- Correct multimeter probe placement and range selection for AC measurements
- Function generator waveform configuration (frequency, amplitude, offset)
- Oscilloscope triggering and reading peak-to-peak, RMS, and period values
Which of the 12 Domains Trip Up Candidates Most
CertTEC's published AC competency topics span 12 domains: Principles of Alternating Current, Electronic Components and Terms, Principles of Inductance, Transformer Theory, Principles of Capacitance, AC Generator Theory, AC Motor Theory, RC/RL/RCL Principles, Cabling, Test Equipment and Measurements, Basic Electrical Safety Precautions, and Mathematics and Formulas. Each domain contributes to the practical tasks scored during the assessment, but two areas consistently demand the most rehearsal time based on the exam's stated practical focus: transformer winding fault diagnosis and RC/RL circuit troubleshooting.
Domain 4: Transformer Theory
Candidates must be able to identify winding faults on a live circuit card, not just describe turns-ratio math from memory.
- Primary/secondary winding fault isolation using the multimeter
- Turns-ratio calculations tied to measured voltages
- Recognizing shorted, open, and grounded winding symptoms on the oscilloscope
Domain 8: RC, RL, and RCL Principles
This domain blends math and instrumentation - candidates must predict circuit behavior and then confirm it on the scope.
- Phase angle relationships between voltage and current
- Time constant calculations for charge/discharge behavior
- Troubleshooting sequences when a component fails within an RC or RL network
For a full domain-by-domain breakdown with weighting context, review BEE-AC Exam Domains 2026: Complete Guide to All 12 Content Areas. Knowing which domains carry the heaviest practical burden is far more actionable than any single pass rate percentage.

The Equipment Factor: A Hidden Variable in Outcomes
One reason a single pass rate figure would obscure more than it reveals is that outcomes are tied to equipment familiarity as much as conceptual mastery. A candidate who studied AC theory extensively but has limited hands-on time with a Nida 130E trainer or an oscilloscope enters the assessment at a disadvantage compared to someone with equal theoretical knowledge and more bench time.
This is why programs and training providers that give candidates repeated access to the exact equipment combination - circuit cards, trainer, multimeter, function generator, and oscilloscope together - tend to produce more consistent results than theory-only study. If your preparation so far has been reading-heavy, prioritize scheduling time on physical equipment before your exam date. The BEE-AC Study Guide 2026: How to Pass on Your First Attempt covers how to structure that hands-on practice alongside conceptual review.
Eligibility Routes and Their Effect on Readiness
CertTEC allows several paths to sit for BEE-AC: relevant training or work experience, a relevant military rating or assignment, or graduation from a relevant college or technical-school program. Each route tends to produce candidates with different strengths and gaps heading into the assessment.
- Work-experience candidates often have strong hands-on instincts but may need to formalize their math and formula recall for Domain 12.
- Military-trained candidates frequently have solid safety-procedure habits (Domain 11) but may need refreshers on civilian test-equipment conventions.
- Program graduates usually have strong theoretical grounding across Domains 1, 3, 5, and 6 but may need more repetitions on the Nida trainer to build speed.
Understanding which eligibility route you're using - and where it tends to leave gaps - is a more reliable predictor of your personal readiness than any general pass rate figure would be. Full eligibility details are covered in BEE-AC Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Recertification: A Different Kind of Pass Rate
BEE-AC certification is valid for 3 years, and how candidates choose to renew says a lot about long-term retention of the material - arguably a more useful signal than an initial exam pass rate. CertTEC offers three renewal alternatives:
- Verified relevant employment during at least 12 of the preceding 36 months
- At least 18 Alternate Recertification Credits earned within the certification period
- An equivalent knowledge exam
Renewal fees vary by path: USD 10 for an emailed work-verification certificate, USD 25 for a mailed hard copy and/or ID card, USD 15 for the credit route, and USD 50 for the knowledge exam route. Candidates who stay active in AC-related work between certifications generally find the employment-verification route the least burdensome, since it avoids re-testing entirely. Full cost details across both initial certification and renewal are broken down in BEE-AC Certification Cost 2026: Complete Pricing Breakdown.
Key Takeaway
If you expect gaps in employment after certifying, plan to accumulate Alternate Recertification Credits early rather than waiting until your 3-year window is nearly up.

Frequently Asked Questions
No. CertTEC does not release a public pass rate percentage for BEE-AC. Candidates should focus on the published 70% passing score and the specific tasks assessed rather than a statistical benchmark.
The format is different rather than simply "harder" - it's a proctored, in-person performance assessment requiring hands-on use of a Nida 130E trainer, multimeter, function generator, and oscilloscope, so success depends on physical skill as much as recall.
CertTEC sets the passing score at 70%. See the passing score guide for how that threshold applies to specific performance tasks.
Given the exam's stated practical focus, prioritize Transformer Theory, RC/RL/RCL Principles, and Test Equipment and Measurements, since these map directly to the hands-on tasks performed during the assessment.
Certification is valid for 3 years. Renewal can be completed through verified employment, Alternate Recertification Credits, or a knowledge exam, so there isn't a single retest-based pass rate to track at renewal time.
