What the BEE-AC Certification Actually Tests
BEE-AC - Basic Electricity and Electronics, Alternating Current - is a performance-based credential issued by CertTEC, a division of SpaceTEC Partners, Inc. Unlike a purely knowledge-based test, BEE-AC asks candidates to physically demonstrate that they can set up instruments, take waveform measurements, and troubleshoot AC circuits under proctored conditions. If you're still mapping out what this credential covers before diving into study mode, the overview at What Is BEE-AC? and the deeper terminology breakdown in BEE-AC Meaning are useful starting points.
This guide assumes you already know the acronym and want the practical roadmap: what's tested, how it's delivered, what equipment you'll touch, and how to sequence your prep so nothing catches you off guard on exam day.
Exam Format: What Happens on Test Day
BEE-AC is delivered as a proctored, in-person performance assessment administered through SPI's online Examination Management System. You won't be sitting at a generic testing kiosk clicking through questions - you'll be working directly with physical circuit cards and bench equipment while a proctor observes and records your performance against the scoring criteria.
Each discipline uses two CertTEC assessment circuit cards, paired with a Nida 130E or later trainer. You'll also need a multimeter, a function generator, and an oscilloscope on hand to complete the required measurements and troubleshooting tasks. If any of that equipment is unfamiliar, don't wait until test day to find out - get time on each instrument well before you schedule your session.
The passing score is 70%. For a full breakdown of how that score is structured and what "passing" actually means in a performance-assessment context, see BEE-AC Passing Score 2026: Exactly What You Need to Pass.
Key Takeaway
Because this is a performance exam, practicing with an actual multimeter, function generator, and oscilloscope matters more than drilling flashcards. Schedule bench time, not just reading time.
The 12 Domains You Must Master
CertTEC publishes 12 AC competency domains for this certification. Each one shows up in the practical tasks you'll perform on the assessment circuit cards, so treat this list as your master checklist rather than an abstract syllabus. A full domain-by-domain walkthrough lives at BEE-AC Exam Domains 2026: Complete Guide to All 12 Content Areas, but here's the practical framing for each.
Domain 1: Principles of Alternating Current
Covers the foundational behavior of AC voltage and current - sine waves, frequency, phase, and RMS values that underpin everything else on the exam.
- Be able to read and interpret waveform characteristics on an oscilloscope, not just describe them verbally.
Domain 2: Electronic Components and Terms
Tests recognition and functional understanding of the components you'll encounter on the CertTEC assessment cards.
- Know component symbols and how each behaves in an AC context, not just DC.
Domain 3: Principles of Inductance
Focuses on inductive reactance, phase relationships between voltage and current in inductive circuits, and how inductors respond to changing frequency.
Domain 4: Transformer Theory
One of the heaviest practical domains - expect to diagnose transformer winding faults directly on the assessment circuit cards.
- Practice identifying open, shorted, and grounded windings using your multimeter before test day.
Domain 5: Principles of Capacitance
Covers capacitive reactance, charge/discharge behavior, and how capacitors interact with AC signals.
Domain 6: AC Generator Theory
Tests understanding of how AC generators produce alternating voltage, including basic construction and output characteristics.
Domain 7: AC Motor Theory
Covers principles behind AC motor operation, relevant for candidates coming from technician or maintenance backgrounds.
Domain 8: RC, RL, and RCL Principles
Combines resistive, capacitive, and inductive elements into full circuit analysis - a core practical troubleshooting focus of the exam.
- Practice diagnosing RC and RL circuits on the Nida trainer using your function generator and oscilloscope together.
Domain 9: Cabling
Tests knowledge of cable types, terminations, and practical handling relevant to AC circuit work.
Domain 10: Test Equipment and Measurements
Directly tied to instrument setup and use - this is where your comfort with the multimeter, function generator, and oscilloscope is scored.
- Know how to correctly set up each piece of test equipment before taking a measurement, since setup errors cost points.
Domain 11: Basic Electrical Safety Precautions
Covers safe handling procedures around live AC circuits and test equipment - non-negotiable knowledge for a performance assessment.
Domain 12: Mathematics and Formulas
Covers the calculations underlying reactance, impedance, and power in AC circuits - you'll need to apply these formulas quickly during hands-on tasks.
Eligibility Routes and Fee Mechanics

A Domain-Based Study Timeline
Rather than a generic weekly template, sequence your prep around which domains are heaviest on hands-on skill versus recall. Domains involving equipment (Domain 10), transformer fault diagnosis (Domain 4), and RC/RL troubleshooting (Domain 8) need the most bench repetitions, so front-load equipment familiarity early and revisit it throughout.
Foundations and Equipment Orientation
- Review Domain 1 (Principles of Alternating Current) and Domain 12 (Mathematics and Formulas) together, since AC math underlies every later domain.
- Get hands-on with the multimeter, function generator, and oscilloscope even before touching the assessment circuit cards.
Reactive Components
- Work through Domain 3 (Inductance) and Domain 5 (Capacitance) side by side, comparing reactance behavior in each.
- Practice component identification for Domain 2 using real parts if possible.
Transformers and Combined Circuits
- Spend the bulk of this week on Domain 4 (Transformer Theory), simulating winding-fault diagnosis on the Nida trainer.
- Move into Domain 8 (RC, RL, and RCL Principles) once transformer fault patterns feel familiar.
Machines, Safety, and Full Run-Throughs
- Cover Domain 6 (AC Generator Theory), Domain 7 (AC Motor Theory), Domain 9 (Cabling), and Domain 11 (Basic Electrical Safety Precautions).
- Run full timed practice sessions combining instrument setup (Domain 10) with troubleshooting tasks to simulate exam conditions.
Getting Comfortable With the Required Equipment
Because BEE-AC is a performance exam, equipment fluency is arguably as important as domain knowledge. You'll need to demonstrate correct setup and use of:
- A multimeter for voltage, resistance, and continuity checks tied to transformer and RC/RL fault-finding.
- A function generator to supply test signals for waveform and reactance-related measurements.
- An oscilloscope to read and interpret waveform behavior in real time.
- A Nida 130E or later trainer, which houses the circuit configurations you'll be working on.
- Two CertTEC assessment circuit cards per discipline, which contain the actual fault scenarios and circuit builds you'll be assessed against.
If you have access to a lab or training program before your exam date, use it specifically to rehearse instrument setup sequences - many performance-exam point losses come from setup order errors rather than incorrect final answers.
Mistakes That Sink First Attempts
Most first-attempt failures on performance-based exams like BEE-AC trace back to a handful of avoidable issues rather than a lack of theoretical knowledge:
- Treating it like a written exam. Candidates who only study formulas and diagrams without touching real equipment often struggle with the physical setup steps under proctored time pressure.
- Skipping transformer fault practice. Domain 4 requires diagnosing winding faults hands-on - this is not something you can shortcut with memorization alone.
- Underestimating math speed. Domain 12 calculations need to be fast and accurate since they feed into decisions you make during the practical tasks.
- Ignoring safety procedure details. Domain 11 content is graded alongside your technical performance, so overlooking safety steps can cost points even on an otherwise correct task.
