What Is BEE-AC?
BEE-AC stands for Basic Electricity and Electronics - Alternating Current. It is a performance-based certification that measures whether a technician can actually set up test equipment, take waveform measurements, and troubleshoot AC circuits - not just recite formulas. Unlike a purely written exam, BEE-AC asks candidates to demonstrate hands-on competence with real components: assessment circuit cards, a trainer, and standard bench instruments.
The certification sits inside a broader technician-competence framework built around foundational AC theory: inductance, capacitance, transformers, generators, motors, RC/RL/RCL networks, cabling, and safe measurement practice. If you're still mapping out what the credential covers content-wise, the BEE-AC Exam Domains 2026: Complete Guide to All 12 Content Areas breaks each topic down in more depth than a single overview article can.
Who Administers BEE-AC
BEE-AC is issued by CertTEC, a division of SpaceTEC Partners, Inc. CertTEC develops technician-level assessments designed to be delivered where the equipment already lives - training labs, technical schools, and employer test sites - rather than in a generic testing center. That's why the exam format leans so heavily on physical instrumentation instead of a screen full of multiple-choice questions.
Because the certifying body focuses on demonstrated skill, employers evaluating candidates for AC electricity and electronics roles can treat a BEE-AC credential as evidence of bench-level competence, not just exam-day recall. If you want a fuller picture of the credential itself before deciding whether to pursue it, see BEE-AC Certification or the more concise What Is BEE-AC Certification?.
How the BEE-AC Exam Works
BEE-AC is delivered as a proctored, in-person performance assessment through SPI's online Examination Management System. This means a proctor observes the candidate working through practical tasks rather than simply administering a timed multiple-choice test.
To sit for the exam, a testing site is equipped with:
- Two CertTEC assessment circuit cards per discipline
- A Nida 130E or later trainer
- A multimeter
- A function generator
- An oscilloscope
Candidates use this equipment to complete tasks such as instrument setup, waveform measurement, transformer winding fault identification, and RC/RL circuit troubleshooting - the same practical skill areas emphasized across the domain list. The exam fee is USD 100 per certification, and the passing score is 70%.

Key Takeaway
Because BEE-AC is equipment-based, practicing on an actual multimeter, function generator, and oscilloscope matters more than memorizing definitions alone.
The 12 BEE-AC Domains
CertTEC organizes BEE-AC content into 12 published AC competency domains. Every question and practical task on the exam maps back to one of these areas:
- Principles of Alternating Current
- Electronic Components and Terms
- Principles of Inductance
- Transformer Theory
- Principles of Capacitance
- AC Generator Theory
- AC Motor Theory
- RC, RL, and RCL Principles
- Cabling
- Test Equipment and Measurements
- Basic Electrical Safety Precautions
- Mathematics and Formulas
Domain 4: Transformer Theory
Candidates must be able to explain winding relationships and identify faults introduced into a transformer under test.
- Recognizing shorted, open, or reversed windings using measured voltages
- Relating turns ratio to voltage and current changes across primary and secondary
Domain 10: Test Equipment and Measurements
This domain ties directly into the physical equipment used during the assessment itself.
- Correct multimeter and oscilloscope setup for AC signals
- Reading and interpreting waveforms generated on a function generator
Domain 8: RC, RL, and RCL Principles
Troubleshooting resistive-capacitive and resistive-inductive circuits is a core practical task on the performance assessment.
- Identifying phase relationships between voltage and current
- Isolating faults in combined RC/RL/RCL networks using bench instruments
Because the exam is performance-based, domains like Test Equipment and Measurements and Basic Electrical Safety Precautions aren't abstract - they're demonstrated live with the trainer and instruments in front of a proctor. A domain-by-domain study plan, including how much attention each topic deserves relative to the others, is covered in the BEE-AC Study Guide 2026: How to Pass on Your First Attempt.
Who Can Earn BEE-AC
CertTEC offers several routes into the BEE-AC assessment rather than a single fixed prerequisite. A candidate can typically qualify through:
- Relevant training or documented work experience in AC electricity/electronics
- A relevant military rating or job assignment
- Graduation from a relevant college or technical-school program
This flexible eligibility structure is designed to accommodate technicians coming from apprenticeships, military electronics tracks, and formal technical education alike. For a detailed walkthrough of which documentation qualifies under each route, see BEE-AC Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Employers hiring for AC electricity and electronics maintenance, avionics-adjacent, and technical field-service roles often look for a demonstrated, hands-on credential like this as a screening signal.

Keeping BEE-AC Current
A BEE-AC certification is valid for 3 years from the date it's issued. Before it expires, holders have three renewal paths:
| Renewal Path | Requirement | Fee |
|---|---|---|
| Verified work experience | Employment in a relevant role for at least 12 of the preceding 36 months | USD 10 (emailed certificate) / USD 25 (mailed hard copy and/or ID card) |
| Alternate Recertification Credits | At least 18 credits earned within the certification period | USD 15 |
| Knowledge exam | Pass an equivalent knowledge-based exam | USD 50 |
Choosing a renewal path is largely a matter of what's easiest to document - steady employment history, accumulated credits, or a willingness to sit for another exam. Anyone mapping out the calendar around initial testing and renewal deadlines should review BEE-AC Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Preparing for the Performance Assessment
Because BEE-AC is scored on live performance rather than a pure written test, preparation should mirror the actual tasks: setting up instruments, reading waveforms, and tracing faults - not just reviewing flashcards. A practical way to sequence study is to group domains by the equipment they touch. For example, Test Equipment and Measurements, Principles of Alternating Current, and Mathematics and Formulas build the baseline skills used in nearly every other domain, so they're worth mastering early rather than saving for the final week before the exam.
Component- and circuit-heavy domains - Inductance, Capacitance, Transformer Theory, and RC/RL/RCL Principles - benefit from repeated hands-on practice with a trainer, since the performance assessment asks you to identify faults under time pressure rather than describe them in the abstract. Safety Precautions and Cabling round out the list and tend to be faster to review once the circuit-based domains are solid.
