Choosing the right electrician exam prep can mean the difference between passing on your first attempt and paying to retake it. But with dozens of options claiming the highest pass rates, it's hard to know who to trust. We tested 8 of the most popular exam prep platforms for journeyman and master electrician exams to give you an honest, side-by-side comparison.
Some of these platforms have been around for decades. Others launched in the last two years. We evaluated each one on question quality, NEC accuracy, pricing transparency, mobile access, and whether they actually prepare you for the way modern licensing exams work. No fluff, no paid rankings — just what we found after spending real time with each one.
Quick Verdict
Short on time? Here are our top picks by category:
Only platform that bundles exam prep, OJT tracking, NEC calculators, and community in one app. Free tier available.
50+ years of NEC education. The gold standard for understanding the WHY behind code articles. Best illustrations in the industry.
Covers all 51 jurisdictions with state-specific content. Combines continuing education credits with exam prep.
How We Evaluated
We didn't just read marketing pages. We signed up for every platform, worked through their question banks, and evaluated them on six criteria that actually matter for passing your exam:
Are questions exam-realistic? Do they match PSI/Prometric format?
Are code references correct? Is the NEC edition current for your state?
Is the price clear upfront? Any hidden costs or aggressive upsells?
Can you study from your phone on break? Is there a native app?
Does it identify your weak areas and adjust? Or is it just a static question bank?
Is there a forum, Discord, or way to ask questions when you get stuck?
Each platform was scored against these criteria during hands-on testing. We also surveyed working electricians and apprentices about their real-world experience with these tools. Here are the results, ranked by overall value.
1. SparkShift — Best All-in-One Platform
SparkShift is the only platform we tested that combines electrician exam prep with OJT hour tracking, NEC calculators, and a community forum. If you're an apprentice juggling hours documentation, exam study, and code lookups across three different apps, SparkShift consolidates everything into one.
The exam prep module uses AI-adaptive question delivery. It tracks which NEC articles you struggle with and surfaces more questions in those areas. Questions are based on the NEC 2026 code cycle and formatted to match the style you'll see on PSI and Prometric licensing exams. After each question, you get a detailed explanation with the specific NEC article reference.
Beyond the test prep, SparkShift includes 200+ NEC calculators (box fill, conduit fill, voltage drop, service sizing, and more), a full NEC code reference, and a community forum where you can ask questions and get answers from other apprentices and journeymen.
Pros
- OJT tracking + exam prep + calculators in one app
- AI-adaptive questions that target your weak areas
- 200+ NEC calculators built in
- NEC code reference tool
- Community forum for questions
- NEC 2026 ready
- Free tier with 5 questions per day
- Mobile-first design (iOS and web)
Cons
- Newer platform (launched 2025) — less brand recognition
- Question bank still growing compared to 20+ year veterans
- No physical study guide option
The free tier gives you 5 questions per day, which is enough to build a daily study habit. The $29.99/month plan unlocks the full question bank, unlimited practice exams, and all NEC calculators. For an apprentice already paying separately for an hours tracker and a code reference app, the bundled pricing is competitive.
No credit card required
2. Mike Holt Enterprises — Best for Deep NEC Understanding
Mike Holt is the most respected name in NEC education, and for good reason. His company has been producing electrical training materials for over 50 years. If you ask ten journeymen how they studied for their exam, at least half will mention Mike Holt.
What sets Mike Holt apart is the depth of NEC explanation. His materials don't just tell you the answer — they explain why the code says what it says, with detailed illustrations that make complex concepts visual. The “Understanding the NEC” series is widely considered the best NEC reference outside the codebook itself.
The exam prep courses include practice questions organized by NEC article, video lessons, and comprehensive workbooks. The quality of content is consistently excellent. Mike Holt has set the standard for NEC education for decades, and the material reflects that expertise.
Pros
- 50+ year track record — the gold standard for NEC education
- Best illustrations and visual explanations in the industry
- Comprehensive coverage of every NEC article
- Active online forum with knowledgeable community
- Courses for journeyman, master, and inspector exams
- Video content for visual and auditory learners
Cons
- No mobile app — website only, not optimized for phones
- Can get expensive ($200-$500 for full course bundles)
- Website feels dated compared to modern platforms
- No AI or adaptive learning features
- No OJT tracking or calculator tools
- Physical materials can take time to ship
The main downside is the fragmented product lineup. Books, DVDs, online courses, and workbooks are all sold separately, and building a complete study package can add up fast. There's also no mobile app, so studying on break at a job site means navigating the desktop website on your phone.
If your primary goal is deep NEC comprehension and you learn best from detailed explanations and illustrations, Mike Holt is still hard to beat. Many electricians use Mike Holt for learning the material and then switch to a mobile-friendly platform for practice test drilling.
3. JADE Learning — Best for Continuing Education
JADE Learning stands out for its state-specific focus. They offer continuing education courses for all 51 jurisdictions (50 states plus DC), and their exam prep is designed around the specific requirements of each state's licensing exam. If you need CE credits to maintain your license and you're preparing for a master electrician exam, JADE lets you knock out both with one purchase.
The question bank includes 800+ practice questions, and JADE claims an 81% pass rate among users who complete their program. The content is solid and well-organized by NEC article, with explanations that reference specific code sections. Their state-specific pages show you exactly which NEC edition your state uses and what topics are weighted most heavily on your exam.
Pros
- State-specific exam prep for all 51 jurisdictions
- 800+ practice questions with NEC references
- Combines CE credits with exam prep
- 81% claimed pass rate
- Well-organized by NEC article and topic
- Established company with a solid reputation
Cons
- No mobile app — browser only
- Pricing is hard to find without creating an account
- No AI or adaptive features
- No OJT tracking or calculator tools
- Interface looks outdated
- Access expires after your subscription window
The biggest frustration with JADE is the pricing transparency. You often have to navigate through several pages or create an account before you see actual prices. That said, once you're in, the content quality is reliable and the state-specific focus is genuinely useful if you're unsure exactly what your state tests on.
4. Dakota Prep — Best AI Tutor
Dakota Prep is one of the newer entrants in the electrician exam prep space, and they've leaned heavily into AI. Their standout feature is an AI tutor that you can ask questions to as if you were talking to an instructor. Stuck on a grounding calculation? Ask the AI and it walks you through it step by step.
The question bank is solid at 3,000+ questions, and they have a mobile app that works well for studying on the go. The free tier gives you limited daily access, while the $90 Pro plan is a one-time payment for lifetime access — a different pricing model than the monthly subscriptions most competitors use.
They also maintain an active Discord community where users share study tips, ask questions, and support each other through the exam prep process. For electricians who are comfortable with technology, the combination of AI tutoring and community support is compelling.
Pros
- 3,000+ practice questions
- AI tutor for on-demand help
- Mobile app for iOS and Android
- Active Discord community
- $90 one-time payment (Pro) — no recurring fees
- Clean, modern interface
Cons
- Most content locked behind $90 paywall
- Some users report code reference errors in AI answers
- NEC version mismatches reported (mixing 2023 and 2026 content)
- No OJT tracking or calculator tools
- Newer company with less track record
- Free tier is very limited
The concern we heard most from users is accuracy. A few apprentices reported that the AI tutor occasionally cited incorrect NEC article numbers or gave answers based on the wrong NEC edition. AI in education is promising but not perfect yet, so always verify AI-generated code references against your actual codebook. That said, the 3,000+ question bank itself is well-reviewed and the one-time pricing is attractive if you're on a tight budget.
5. 1 Exam Prep — Best Physical Study Guides
If you prefer holding a physical book and tabbing your NEC codebook, 1 Exam Prep is built for you. They sell study guides, practice exam books, and pre-made NEC tab sets for all 50 states. Their journeyman study guide is a consistent Amazon bestseller in the electrician exam prep category.
The NEC tab sets are particularly popular. Properly tabbing your codebook is critical for timed exams where you need to look up code sections quickly. 1 Exam Prep's tabs are organized for speed, with state-specific tabs that align with the topics most commonly tested in your jurisdiction. For many test-takers, the tab set alone is worth the purchase.
Their study guides are well-structured, with practice questions followed by detailed explanations. The content is updated for NEC 2026, and they offer guides for both journeyman and master electrician exams.
Pros
- All 50 states covered with state-specific content
- NEC 2026 ready
- Amazon bestseller — widely reviewed and trusted
- Excellent NEC tab sets for fast code lookups
- Physical books great for focused study sessions
- One-time purchase, no subscription
Cons
- Physical only — no digital app or platform
- No practice test software or adaptive learning
- No AI features or instant feedback
- Shipping time means no instant access
- Can't study from your phone on break
- Higher-end bundles get expensive ($300+)
The limitation is obvious: it's physical only. In 2026, many apprentices want to study from their phone during lunch break or downtime at a job site. 1 Exam Prep doesn't offer that. But for dedicated study sessions at home — especially for people who retain information better from paper than screens — their materials are top-tier.
6. Electrical Code Coach — Best Free YouTube Content
Electrical Code Coach has built one of the best free educational resources for electricians on YouTube. The channel covers NEC code breakdowns, exam tips, calculation walkthroughs, and study strategies in short, focused videos. For apprentices with a long commute, this is gold — you can listen to NEC explanations like a podcast.
The channel's strength is making dense NEC content accessible and even entertaining. Topics are broken into 10-20 minute videos that cover specific code articles or calculation types, making it easy to target your weak areas. The free content alone is more useful than some paid platforms we tested.
Beyond YouTube, Electrical Code Coach sells digital study guides and practice exams ranging from $19.99 to $89.99. The paid materials are solid, but the real value is the free YouTube content as a supplement to whatever primary study platform you choose.
Pros
- Hundreds of free YouTube videos
- Excellent NEC explanations in accessible format
- Great for commute learning (audio works well)
- Affordable digital products ($19.99-$89.99)
- Regularly updated with new content
- Good for visual and auditory learners
Cons
- YouTube isn't structured for systematic study
- No practice test platform or adaptive learning
- No mobile app beyond YouTube
- Paid products are basic compared to full platforms
- No OJT tracking or calculator tools
- Content scattered across many videos
Think of Electrical Code Coach as a supplement, not a standalone solution. Pair their YouTube videos with a structured practice test platform (like SparkShift or Dakota Prep) and you've got a powerful combination at a low price point.
7. Mometrix / Tests.com — Best Free Practice Tests
Mometrix and Tests.com offer free electrician practice tests that can be useful for a quick gut-check of where you stand. If you're wondering whether you're ready for the exam or need more study time, taking a free practice test here gives you a rough baseline without spending money.
The free tier includes a handful of sample questions covering general electrical theory, NEC code, and basic calculations. The premium versions offer more questions, video tutorials, and flashcards.
Pros
- Free practice tests available immediately
- No signup required for basic tests
- Good for initial self-assessment
- Available on any device with a browser
Cons
- Questions are generic — not state-specific
- Thin content compared to dedicated electrical platforms
- Not written by electricians or NEC specialists
- No detailed code references in explanations
- Free tests are very short (10-20 questions)
- Premium pricing is high for what you get
The big caveat: these are generic test prep companies that cover dozens of certification exams across many industries. Their electrician content is not written by NEC specialists, and it shows. Questions tend to be surface-level and don't reflect the depth or code-lookup format of actual PSI/Prometric licensing exams. Use them for a quick baseline, then invest in a platform built specifically for electricians.
8. Tom Henry — Best for Calculations
Tom Henry's books have been a staple of electrician exam prep for years, particularly for the calculation-heavy portions of the exam. His “Key Word Index” for the NEC is legendary among test-takers — it helps you find code sections faster during the exam than the codebook's own index.
Where Tom Henry really shines is calculations. His books break down complex electrical math into step-by-step processes with clear formulas and worked examples. If load calculations, voltage drop, conductor sizing, or service entrance calculations are your weak areas, Tom Henry's materials are specifically designed to make those concepts click.
Pros
- Excellent calculation explanations and practice
- Famous Key Word Index for fast NEC lookups
- Affordable ($30-$60 per book)
- Decades of proven results
- Focused, no-nonsense content
Cons
- Physical books only — no digital or app
- Narrowly focused on calculations and code lookup
- Not a complete exam prep solution by itself
- Website and materials feel very dated
- Limited question bank compared to full platforms
- No practice test platform or AI features
Tom Henry is best used as a supplement for your weakest areas, not as your only study resource. If calculations are where you're losing points, his books are the best targeted resource available. Pair them with a broader platform for full exam coverage.

Frequently Asked Questions
How long should I study for the journeyman electrician exam?
Most electricians study 2-4 months before taking the journeyman exam. Plan for 1-2 hours per day if you have 3+ months, or 3-4 hours daily if you have less time. Focus on NEC code lookup speed first, then calculations, then theory questions. Taking practice tests weekly helps you gauge readiness.
What is the pass rate for the journeyman electrician exam?
Pass rates vary by state and exam provider. PSI and Prometric exams typically have first-attempt pass rates between 55-70%. The most commonly failed sections are NEC code calculations and grounding/bonding. Using a structured exam prep program significantly improves your odds.
Is the NEC 2026 on the electrician exam yet?
NEC code adoption varies by state. As of March 2026, some states have adopted NEC 2026 while others still use NEC 2023 or even NEC 2020. Check your state licensing board website for the current code cycle before choosing study materials. SparkShift, Mike Holt, and 1 Exam Prep all offer NEC 2026 content.
Can I pass the electrician exam with free study materials?
It is possible but significantly harder. Free resources like Electrical Code Coach YouTube videos and SparkShift's free tier (5 daily questions) can supplement your study, but most successful test-takers use at least one paid resource for structured practice tests and code drill exercises. The exam costs $75-$300+ to take, so investing in prep materials often saves money by avoiding retakes.
What's the difference between journeyman and master electrician exam prep?
Master electrician exams cover more advanced topics including load calculations, service sizing, transformer theory, and business/project management. The NEC code lookup skills are the same, but master exams test deeper understanding. Most prep platforms cover both levels, with SparkShift, Mike Holt, and JADE Learning all offering master-level content.
Should I use an app or books to study for the electrician exam?
Both have advantages. Apps like SparkShift and Dakota Prep offer AI-adaptive learning, instant feedback, and mobile convenience for studying during breaks. Books from Mike Holt and 1 Exam Prep provide deeper explanations and work well for focused study sessions. Many successful test-takers use a combination of both.
Final Thoughts
There is no single “best” electrician exam prep — it depends on your learning style, budget, and where you are in your career. A first-year apprentice who needs OJT tracking has different needs than a 10-year journeyman prepping for a master exam.
What we can say after testing all 8 platforms: the days of studying from a single textbook are over. The most successful test-takers combine a primary study platform with supplementary resources. Use a structured practice test tool for daily drilling, add video content for concepts that aren't clicking, and make sure your NEC codebook is properly tabbed for fast lookups.
If you want to try SparkShift, the free tier gives you 5 practice questions per day with no credit card required. It's enough to see if the question style and AI-adaptive approach works for how you study.
