Quick Facts Snapshot
This page is built to be printed, bookmarked, or skimmed the night before your appointment. It condenses everything a candidate needs to know about the Basic Electricity and Electronics Certification - Direct Current (BEE-DC) into one scannable reference - no fluff, no filler. If you want the full narrative version of any section below, the BEE-DC Study Guide 2026 walks through the same material at a slower pace.
BEE-DC is administered by CertTEC, a division of SpaceTEC Partners, Inc. It is delivered as a proctored, in-person performance assessment through SPI's online Examination Management System - meaning you're being scored on what you can actually do with a circuit card and a set of test instruments, not just what you can answer on a multiple-choice screen. The current exam specifications come from the SPI catalog revised March 1, 2025, and the domain list published there is what this cheat sheet follows.
Exam Format, Equipment, and Fees
Unlike many certifications named similarly in other industries, BEE-DC is not a pure written knowledge test. It's a performance assessment: you sit at a bench, build or troubleshoot circuits, and demonstrate competence with real instruments while a proctor scores you through SPI's platform.
- Passing score: 70%
- Exam fee: USD 100 per certification
- Delivery: Proctored, in-person performance assessment via SPI's online Examination Management System
- Equipment required: two CertTEC assessment circuit cards per discipline, a Nida 130E or later trainer, a multimeter, a function generator, and an oscilloscope
Because the equipment list is fixed, it's worth confirming with your test site well in advance that the trainer generation and instruments match what CertTEC specifies - showing up to find an unfamiliar bench layout wastes precious exam time. For a full cost breakdown including how the fee compares across renewal paths, see BEE-DC Certification Cost 2026: Complete Pricing Breakdown.
Key Takeaway
Practice on the exact instrument types listed above - a Nida 130E-class trainer, a multimeter, a function generator, and an oscilloscope - until reading them is automatic. Fumbling with an unfamiliar oscilloscope interface under proctor observation costs more time than any content gap.
The 12 BEE-DC Domains at a Glance
CertTEC's published DC competency topics break the exam into twelve domains. None of these is optional - the performance assessment expects fluency across theory, safety, components, math, measurement, circuit topology, and power supplies. The condensed list below pairs each domain with the single most important thing to remember about it.
Domain 1: Basic Electrical Theory
Foundational vocabulary and relationships - voltage, current, resistance, and power as they relate to each other in a DC circuit.
- Be able to explain each quantity without relying on a formula sheet
Domain 2: Magnetism
How magnetic fields relate to current flow, and the basic principles that connect magnetism to electrical devices.
- Know polarity rules and field direction conventions cold
Domain 3: Basic Electrical Safety
Safe handling of live circuits, meters, and bench equipment - this domain is graded on habits, not just recall.
- Proctors watch for correct meter setup and lead handling during the practical portion
Domain 4: Electronic Equipment
Recognizing and correctly operating the bench equipment used throughout the exam, including trainers and test instruments.
- Practice setting up the function generator and oscilloscope from a cold start
Domain 5: Electronic Components
Identification and function of common DC components on the CertTEC assessment circuit cards.
- Match component symbols to physical parts on the trainer, not just on paper
Domain 6: Ohms Law for Electronics
The exam's practical core: calculating voltage, current, or resistance and then verifying the result with a multimeter reading.
- Every calculation should be checked against a real meter reading during practice
Domain 7: Basic Mathematics for Electronics
The arithmetic and algebra that support every other domain - unit conversions, rearranging formulas, and working with scientific notation.
- Slow, careless math errors are a common reason candidates lose points elsewhere
Domain 8: Electronic Measurements
Correct multimeter, function generator, and oscilloscope technique for measuring voltage, current, resistance, and waveforms.
- Know when to measure in-circuit versus out-of-circuit
Domain 9: Series Circuits for Electronics
Current is constant, voltage divides - and you must diagnose faults such as opens and shorts in a series arrangement.
- Practice predicting meter readings before you touch the probes
Domain 10: Parallel Circuits for Electronics
Voltage is constant across branches, current divides - fault diagnosis here often hinges on spotting an open branch.
- Compare expected total resistance against your calculated value every time
Domain 11: Series/Parallel Combination Circuits for Electronics
The most demanding domain: combining series and parallel rules to analyze and troubleshoot mixed-topology circuits.
- Redraw complex circuits into simpler equivalent blocks before calculating
Domain 12: Battery Power Supplies
DC power supply characteristics, battery behavior, and how supply performance affects circuit readings.
- Understand loaded versus no-load voltage differences
For a deeper breakdown of how these twelve domains interact and where candidates most often underestimate the workload, read BEE-DC Exam Domains 2026: Complete Guide to All 12 Content Areas.
Core Concepts You Must Have Memorized
The practical focus of BEE-DC comes down to two repeated skills, exercised in every domain from 6 through 11: Ohm's law calculations checked against multimeter readings, and fault diagnosis across series, parallel, and series-parallel circuits. If you can do these two things fast and correctly, most of the exam falls into place.
- Calculate, then confirm. Never treat a calculated value as final - the exam wants you to verify it against a real multimeter reading on the assessment circuit card.
- Know your topology tells. In series circuits, current stays the same everywhere; in parallel circuits, voltage stays the same across branches. Combination circuits require you to identify which rule applies to which section.
- Fault patterns repeat. Opens, shorts, and out-of-tolerance components produce predictable, recognizable meter signatures - drill these until you recognize them instantly.
- Instrument fluency is scored. Correctly using the function generator and oscilloscope isn't a side skill; it's part of Domains 4 and 8 directly.

Eligibility Routes Before You Register
Before you pay the USD 100 fee, confirm you qualify through one of the recognized paths:
- Relevant training or work experience in electronics or a related field
- A relevant military rating or assignment
- Graduation from a relevant college or technical-school program
None of these routes require a specific number of years or a specific school by name in the general guidance - the key is that the training, assignment, or program is relevant to DC electronics fundamentals. If you're piecing together which route applies to your background, BEE-DC Requirements 2026: Eligibility, Prerequisites & How to Qualify walks through each path in more detail.
Renewal and Recertification Cheat Sheet
BEE-DC is valid for 3 years from the date of certification. When it's time to renew, you have three alternatives - no single path is mandatory:
| Renewal Path | Requirement | Fee |
|---|---|---|
| Verified work experience | Employment verified during at least 12 of the preceding 36 months | USD 10 (emailed certificate) or USD 25 (mailed hard copy/ID card) |
| Alternate Recertification Credits | At least 18 credits earned within the certification period | USD 15 |
| Knowledge exam | Pass an equivalent knowledge exam | USD 50 |
Notice that the cheapest paths are experience-based, not exam-based - if you're actively working in the field, verified employment is usually the most economical way to keep your credential current. This is a detail worth building into your longer-term career plan, alongside how the certification fits into hiring conversations covered in BEE-DC Jobs.
Key Takeaway
Mark your 3-year expiration date the moment you certify, and start tracking either employment months or Alternate Recertification Credits well before the deadline so you're not forced into the USD 50 knowledge-exam path by default.
