- BEE-AC is issued by CertTEC, a division of SpaceTEC Partners, Inc.
- It's a proctored, in-person performance assessment, not a multiple-choice-only exam.
- The exam fee is USD 100, and you need a 70% score to pass.
- Certification is valid for 3 years, with three distinct renewal paths.
What Is BEE-AC Certification?
BEE-AC stands for Basic Electricity and Electronics - Alternating Current, a hands-on credential that verifies a technician can safely and competently work with AC circuits, components, and test equipment. Unlike many IT or electrical certifications that rely purely on multiple-choice knowledge tests, BEE-AC is built around a proctored, in-person performance assessment - candidates are watched setting up instruments, taking waveform measurements, and diagnosing faults on real circuit hardware.
The certification is administered by CertTEC (Certifying Technical Employee Competence), a division of SpaceTEC Partners, Inc. It's designed for people entering or advancing in electronics maintenance, avionics, industrial electrical work, and similar technical fields where AC theory has to translate into physical troubleshooting skill, not just test-taking ability. If you're brand new to the acronym itself, our companion piece on What Is BEE-AC? covers the term from a broader angle, while this article focuses specifically on the certification process.
Who Issues the BEE-AC Credential
CertTEC operates as a division of SpaceTEC Partners, Inc., and administers BEE-AC alongside other technical competency certifications. Exams are delivered through SPI's online Examination Management System, which handles scheduling and proctoring logistics for the in-person testing session. This is a detail worth remembering: even though the assessment is physically hands-on, the scheduling and administrative backbone runs through that online system, so candidates should expect to register and manage their exam appointment digitally even though the test itself happens on a bench with real hardware.
For a deeper dive into how the certifying body structures the credential itself - including how it differs from casual terminology - see BEE-AC Certification and BEE-AC Meaning.
Exam Format: What Actually Happens on Test Day
The BEE-AC assessment is a proctored, in-person performance exam. Rather than answering questions on a screen alone, candidates work with physical equipment to demonstrate real competency. The specified equipment set includes:
- Two CertTEC assessment circuit cards per discipline
- A Nida 130E or later trainer
- A multimeter
- A function generator
- An oscilloscope
Candidates are expected to set up this equipment correctly, take accurate measurements, and troubleshoot circuit faults live - not just describe the theory behind them. Typical practical focus areas include instrument setup and configuration, waveform measurement and interpretation, identifying transformer winding faults, and troubleshooting RC and RL circuits under load. This is very different from a typical closed-book knowledge exam, and it's a major reason many candidates underestimate the exam's true difficulty. If you want a detailed breakdown of how challenging the practical component tends to be relative to the written domains, read How Hard Is the BEE-AC Exam? Complete Difficulty Guide 2026.
Key Takeaway
Practice physically handling a multimeter, function generator, and oscilloscope before test day - familiarity with the controls under time pressure matters as much as knowing the underlying theory.
The 12 BEE-AC Domains
CertTEC's published AC competency topics break the exam into twelve domains. Each one represents a body of knowledge and skill that can show up in either the theoretical questioning or the hands-on performance tasks.
Domain 1: Principles of Alternating Current
Foundational AC theory - waveform generation, frequency, phase, and the mathematical relationships that describe alternating signals.
- Sine wave characteristics and phase relationships
Domain 3: Principles of Inductance & Domain 5: Principles of Capacitance
How inductors and capacitors store and release energy in AC circuits, and how their reactive behavior changes with frequency.
- Reactance calculations and phase shift effects
Domain 4: Transformer Theory
Transformer construction, turns ratios, and - notably - diagnosing winding faults, which is a recurring practical task on the performance portion of the exam.
- Identifying shorted or open windings using test equipment
Domain 8: RC, RL, and RCL Principles
Combined resistive-reactive circuit behavior, a frequent source of hands-on troubleshooting scenarios during the assessment.
- Predicting and verifying circuit response with an oscilloscope
The remaining domains round out the full scope of the credential: Domain 2 (Electronic Components and Terms), Domain 6 (AC Generator Theory), Domain 7 (AC Motor Theory), Domain 9 (Cabling), Domain 10 (Test Equipment and Measurements), Domain 11 (Basic Electrical Safety Precautions), and Domain 12 (Mathematics and Formulas). For a full walkthrough of all twelve areas with study guidance for each, see BEE-AC Exam Domains 2026: Complete Guide to All 12 Content Areas.

| 1. Principles of Alternating Current | Waveforms, frequency, phase |
| 2. Electronic Components and Terms | Component identification and terminology |
| 3. Principles of Inductance | Inductive reactance and energy storage |
| 4. Transformer Theory | Turns ratios, winding fault diagnosis |
| 5. Principles of Capacitance | Capacitive reactance and charge/discharge |
| 6. AC Generator Theory | Generator construction and output |
| 7. AC Motor Theory | Motor types and operating principles |
| 8. RC, RL, and RCL Principles | Combined circuit troubleshooting |
| 9. Cabling | Wiring practices and standards |
| 10. Test Equipment and Measurements | Meter, generator, and scope use |
| 11. Basic Electrical Safety Precautions | Safe handling and lockout practices |
| 12. Mathematics and Formulas | AC calculations and formula application |
Eligibility Routes
BEE-AC doesn't require a single fixed prerequisite. CertTEC recognizes multiple paths into eligibility, which makes the credential accessible to people coming from different backgrounds:
- Relevant training or hands-on work experience in electronics or electrical maintenance
- A relevant military rating or duty assignment involving electrical or electronics work
- Graduation from a relevant college or technical-school program
This flexibility means veterans transitioning out of technical military roles, graduates of electronics programs, and self-taught technicians with verifiable work history can all pursue the same certification through different documented routes. For the exact documentation and verification details each route typically requires, see BEE-AC Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Cost and Fee Structure
The exam fee for BEE-AC is USD 100 per certification. That single fee covers the proctored performance assessment delivered through the SPI Examination Management System. Beyond the initial exam, candidates should budget separately for renewal costs down the line - those vary depending on which renewal path is chosen, and are detailed in the renewal section below.
Because the fee structure is fairly compact compared to some multi-part credentialing programs, it's worth understanding exactly what's included before you register. A full breakdown of the fee alongside renewal pricing is available in BEE-AC Certification Cost 2026: Complete Pricing Breakdown.
Passing Score and Scoring
To pass BEE-AC, candidates need a score of 70%. Because the exam blends conceptual questioning across the 12 domains with a hands-on performance component, a 70% threshold means there's limited room for guessing your way through - accuracy on equipment setup and measurement tasks counts directly toward that score. For a domain-by-domain look at how the passing threshold interacts with question weighting, check BEE-AC Passing Score 2026: Exactly What You Need to Pass.
Validity and Renewal
Once earned, BEE-AC certification is valid for 3 years. CertTEC offers three distinct ways to renew before it lapses:
- Work verification: documented, verified relevant employment during at least 12 of the preceding 36 months
- Credit accumulation: earning at least 18 Alternate Recertification Credits within the certification period
- Knowledge exam: passing an equivalent knowledge-based exam
Renewal fees differ by path: work verification renewal costs USD 10 for an emailed certificate or USD 25 for a mailed hard copy and/or ID card; the credit route costs USD 15; and the knowledge-exam route costs USD 50. Choosing the right path often comes down to whether you've stayed continuously employed in a relevant role or need an alternative option because your work history has gaps.
Who Hires BEE-AC-Certified Technicians
Because the assessment emphasizes hands-on skill with AC circuits, transformers, and standard bench test equipment, BEE-AC tends to appeal to employers hiring for electronics maintenance, avionics support, industrial electrical technician, and similar roles where a technician must diagnose real circuit problems rather than just discuss theory. The credential's emphasis on transformer winding faults and RC/RL troubleshooting in particular signals to employers that a candidate can be productive on day one with standard shop tools like a multimeter, function generator, and oscilloscope.

Mapping a Study Plan to the Domains
Because BEE-AC combines theory across 12 domains with a physical performance component, an effective prep plan needs to alternate between reading/review and actual bench time - not just repeated flashcard review.
Foundational Theory
- Work through Domain 1 (Principles of Alternating Current) and Domain 12 (Mathematics and Formulas) since later domains build on these
- Review Domain 2 (Electronic Components and Terms) for vocabulary you'll need during the practical
Reactive Components
- Study Domain 3 (Inductance) and Domain 5 (Capacitance) together, comparing their behavior
- Move into Domain 8 (RC, RL, and RCL Principles) once both are solid
Machines and Transformers
- Cover Domain 4 (Transformer Theory), focusing on winding-fault identification
- Study Domain 6 (AC Generator Theory) and Domain 7 (AC Motor Theory)
Practical & Safety
- Get physical time on a multimeter, function generator, and oscilloscope for Domain 10
- Finish with Domain 9 (Cabling) and Domain 11 (Basic Electrical Safety Precautions)
Standard techniques like spaced repetition and short focused review blocks still apply here, but they should be scheduled around bench practice rather than replacing it - the performance assessment simply can't be passed through reading alone. For a more complete week-by-week strategy, see the BEE-AC Study Guide 2026: How to Pass on Your First Attempt, and once you're closer to test day, run through the condensed BEE-AC Cheat Sheet 2026: One-Page Review of Must-Know Facts and take timed practice questions on our practice test platform to check readiness across all twelve domains.
Key Takeaway
Don't save equipment practice for the final week - bench familiarity with the multimeter, function generator, and oscilloscope needs to be built gradually alongside domain theory, not crammed at the end.
