What Is DE-ME Certification?
DE-ME refers to the Delaware Master Electrician License Exam, the credentialing test administered on behalf of the Delaware Board of Electrical Examiners. It is one of several electrical licenses recognized in the state, and it is important to keep it distinct from the Master Electrician Special and Limited Electrician license tracks - the exam content, eligibility routes, and scope of work differ between these categories. If you're still getting oriented, our overview pages on What Is DE-ME? and DE-ME Meaning walk through the terminology in plain language, and What Does DE-ME Stand For? clarifies how the acronym is used specifically on this site.
This article focuses on the Master Electrician license path: who administers it, what routes qualify you to sit for it, how the exam is structured, and what happens after you pass.
Who Issues It and Who Administers the Exam
The Delaware Board of Electrical Examiners, operating under the Division of Professional Regulation, is the licensing authority. The Board contracts with Prov as the testing provider, meaning Prov handles exam delivery, scheduling logistics, and the current candidate information bulletin. All licensing decisions - including approval to test and issuance of the license itself - rest with the Board, processed through the DELPROS online licensing system.
This two-party structure (Board for approval and licensing, Prov for testing) is a common source of confusion for first-time applicants. You must be approved by the Board through DELPROS before Prov will let you book an exam appointment. Skipping this step, or submitting incomplete verification paperwork, is one of the most common causes of scheduling delays.
Eligibility Routes to Sit for the Exam
Delaware recognizes multiple paths toward Master Electrician eligibility, and each requires supporting documentation from supervisors and training programs:
- Six years of full-time experience working under a licensed Master Electrician.
- An approved apprenticeship route combining 8,000 supervised work hours with 576 instructional hours, or another Board-approved equivalent training program.
- Four years under a Master Electrician plus two years of technical training, a hybrid route for candidates with formal coursework.
Whichever route you choose, the Board requires supervisor verification and education verification documents that match the specific path claimed. There's an added wrinkle for experience accrued in Delaware: any work performed after June 30, 2012 counts toward eligibility only if it was completed under appropriate apprentice or journeyperson licensure at the time. Unlicensed hands-on work after that date generally will not satisfy the experience requirement, so candidates piecing together hours from multiple employers should double-check licensure status for each stretch of work history.
For a full breakdown of documentation requirements and how to avoid application rejections, see DE-ME Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Key Takeaway
If any portion of your Delaware work experience occurred after June 30, 2012, confirm you held the correct apprentice or journeyperson license during that period - otherwise it may not count toward Master eligibility.
Exam Format, Fees, and Scoring
The Master Electrician exam consists of 80 questions delivered in a 3-hour window. It is computer-administered and, notably, open book - candidates may use approved reference materials during the test. A passing score is 75%.
Fee structure has two components that candidates frequently underestimate when budgeting:
- Prov examination fee: $100
- Board application fee: $203
- Combined total: $303, before books, liability insurance, or other incidental expenses

The 10 Exam Domains
The Master Electrician exam blueprint covers ten content domains, each represented by a specific share of the 80 scored questions. General Electrical Knowledge is the largest single domain, which should shape how you allocate study time. The full list:
Domain 1: General Electrical Knowledge
The largest domain on the exam. Covers foundational theory, terminology, and code application principles that underpin every other domain.
- Expect broad coverage rather than a narrow topic set - this domain rewards comprehensive review, not last-minute cramming
Domain 2: Plan Reading
Tests your ability to interpret electrical drawings, schedules, and symbols as they'd appear on a real job site.
Domain 3: Equipment for General Use
Covers switches, receptacles, panelboards, and other commonly installed equipment governed by code requirements.
Domain 4: Wiring & Protection
Overcurrent protection, grounding and bonding, and conductor sizing fall under this domain.
Domain 5: Wiring Methods & Materials
Covers cable types, raceway systems, and installation requirements for various wiring methods.
Domain 6: Motors & Controls
Motor circuit sizing, disconnects, and control circuit fundamentals.
Domain 7: Special Conditions
Emergency systems, standby power, and related code provisions.
Domain 8: Special Equipment
Equipment with dedicated code articles, such as specialized industrial or commercial installations.
Domain 9: Special Occupancies
Hazardous locations and occupancy-specific wiring requirements.
Domain 10: Communication Systems
Low-voltage and communication wiring provisions as they intersect with the broader electrical code.

Complete Difficulty Guide 2026 breaks down what makes this exam challenging beyond raw question count.
Approved References and What You Can Bring
Because the exam is open book, knowing exactly which references are approved - and how you're allowed to mark them up - matters as much as content knowledge. According to Prov's June 24, 2025 candidate information bulletin, the assigned references include the 2020 NEC, the American Electricians' Handbook 17th edition, and Ugly's Electrical References 2020.
However, there's an important timing detail: Delaware has adopted the 2023 NEC, effective January 1, 2026, and the Board specifies that exams are based on the most recently adopted NEC. This means the code edition tied to your exam could shift depending on when you test. Verify Prov's currently assigned exam-book edition before purchasing any reference materials - buying the wrong NEC edition is a completely avoidable and costly mistake.
On what you can bring into the testing room:
- Permitted: approved references, permanent tabs, highlighting, and a simple four-function calculator
- Prohibited: handwritten notes, temporary tabs, and loose inserts
Scheduling, Retakes, and Test Delivery
Once the Board approves your application in DELPROS, you can schedule your exam through Prov. Both traditional test-center appointments and Examroom remote-proctored appointments are available, giving candidates flexibility depending on location and comfort with remote testing environments.
If you don't pass on your first attempt, retakes are available, but only after a minimum seven-day waiting interval. Use that week productively - revisit missed domains rather than simply re-reading the whole code book. For guidance on interpreting your score report and deciding where to focus a retake attempt, see DE-ME Pass Rate 2026: What the Data Shows.

After You Pass: Insurance, Licensing, Renewal
Passing the exam is not the final step. Before the Board will issue your Master Electrician license, you must carry at least $300,000 in general liability coverage. Get quotes and have your policy in place before you finish testing so licensure isn't delayed by an insurance gap.
Once licensed, Master Electrician licenses expire on June 30 of even-numbered years. A full renewal cycle requires 10 approved continuing education hours. Starting with your second renewal, at least 5 of those hours must specifically address the NEC - a detail that catches long-time license holders off guard if they assume any CE credit qualifies. First-time renewals are prorated depending on when your license was originally issued, and liability insurance must remain active throughout the license period, not just at initial issuance.
Key Takeaway
Budget for ongoing costs beyond the $303 exam and application fees: liability insurance premiums and continuing education hours are recurring obligations tied to keeping your Master license active.
Building a DE-ME Study Plan
Given that General Electrical Knowledge carries the largest share of the 80 questions, it deserves the most calendar time - not because other domains are unimportant, but because breadth of coverage there compounds your overall score more than any single narrow domain like Communication Systems or Special Equipment.
General Electrical Knowledge & Wiring & Protection
- Work through overcurrent protection, grounding/bonding, and conductor sizing since these overlap heavily with foundational theory
Plan Reading, Equipment for General Use, Wiring Methods & Materials
- Practice interpreting drawings alongside equipment and wiring-method questions, since plan reading questions often reference installed equipment
Motors & Controls, Special Conditions
- Focus on motor circuit sizing and emergency/standby power provisions
Special Equipment, Special Occupancies, Communication Systems
- Cover the smaller domains and cross-reference against your tabbed NEC sections
Open-Book Simulation
- Practice full 80-question, 3-hour timed simulations using only your permanently tabbed references - no handwritten notes, exactly as required on exam day
