Which Exam This Cheat Sheet Covers
This page is a quick-reference sheet for the Oregon General Journeyman Electrician (J) license examination, administered through the Oregon Department of Consumer and Business Services, Building Codes Division (BCD), under the Electrical and Elevator Board. "OR-JE" is simply this site's shorthand. It is not an official exam code, so you will not find it on BCD forms.
It is not a General Supervising Electrician exam, not a Plant Journeyman exam, and not a limited journeyman credential. If you are still sorting out the terminology, What Is OR-JE? and What Does OR-JE Stand For? cover the naming in more detail. For deeper study planning, pair this sheet with the full OR-JE Study Guide.
Format Facts at a Glance
The Oregon Secretary of State License Directory entry for General Journeyman Electrician (J), updated January 23, 2026, and BCD's Individual Licenses table agree on the core format.
| Item | What the sources support |
|---|---|
| Questions | 52 |
| Time limit | Three hours |
| Style | Written, open-book |
| Passing threshold | 75% |
| Results | Mailed, generally within two weeks |
| Separately timed practical | None verified |
| Scored versus unscored split | Not verified |
| Exact item-type mix | Not verified |
| Public pass rate for this exam | Not verified |
Treat the unverified rows as unknowns, not as reasons to guess. In particular, do not import a supervising-electrician pass rate into your expectations. For what is and is not publicly known, see OR-JE Pass Rate: What the Data Shows and OR-JE Passing Score.
Approval, Scheduling, Fees and Retakes
The order of operations matters more than most candidates expect. BCD arranges testing at approved locations, and you do not simply book a seat first.
- Submit documentation for approval. Experience and education records go to BCD before you arrange the exam. Include the photograph, official training transcripts or apprenticeship-completion evidence, and employer work-experience verification appropriate to your route.
- Receive the authorization letter. Testing happens only after approval.
- Test within 60 days. The 60-day window runs from the date of the authorization letter.
- Wait for results. They are mailed, generally within about two weeks.
- If you fail: wait 30 days and reapply before another authorized attempt.
Fee numbers to remember
- $100 application/license charge.
- $100 renewal.
- A separate current testing-provider fee was not verified. Do not assume the $100 state charge is an exam-sitting fee, and confirm any additional charge when you receive your authorization.
- The published state schedule has no member or non-member pricing.
For a fuller budget view, see OR-JE Certification Cost: Complete Pricing Breakdown. For scheduling mechanics and deadlines, see OR-JE Exam Dates.
Open-Book Rules and the Approved Materials Conflict
"Open-book" does not mean "bring anything." BCD publishes an Approved Material for Electrical Examinations document, and there is a genuine discrepancy you need to handle carefully.
References common to both copies
- The adopted NEC with errata and Oregon amendments
- NEC Handbook with errata
- ORS Chapter 479
- OAR Chapter 918
- American Electrician's Handbook
- Electrical Black Book
- Ugly's Electrical References
- Ferm's Fast Finder
- Tom Henry's Key Word Index
Where the copies disagree
| Topic | 2019-dated rendering | Text marked revised September 2026 |
|---|---|---|
| Tabs | Allowed | Allowed |
| Highlighting | Not clearly addressed in the retrieved summary | Allowed |
| Margin notes | Allowed generally | Limited to cross-references and state/local amendments |
| Calculation examples or extra pages | Not confirmed | Excluded |
| Additional indexes | Not listed | Adds Paul Briganti's key-term index and an Oregon Electrical Code index |
Neither version authorizes practice exams, class-preparation materials, unauthorized inserts, or electronic references. A silent, nonprinting, nonprogrammable calculator is allowed.
Key Takeaway
Do not buy, mark, or tab references based on a forum post or an old checklist. Confirm the latest Letter of Authorization and BCD instructions first, and when in doubt, annotate conservatively: tabs, plus margin notes only if your current instructions clearly permit them.
Code Edition: Adoption Is Not the Same as Exam Transition
BCD's Electrical Code Program lists the 2023 Oregon Electrical Specialty Code, effective October 1, 2023 and based on NEC 2023. BCD's OESC adoption page describes an anticipated October 1, 2026 adoption based on NEC 2026.
The catch: as of the September 30, 2026 research date, an anticipated legal adoption date is not proof of when the J examination switches editions. Your exam authorization and instructions are the authority on which edition you must bring. Buying a book for the wrong cycle is an expensive and avoidable mistake, especially since the NEC with errata and Oregon amendments is the backbone of an open-book test.
Oregon-specific amendments deserve their own tab set. ORS Chapter 479 and OAR Chapter 918 are on the approved list for a reason: this is a state exam, and Oregon rules and law are fair game alongside the national code.
The 15 Curriculum Subjects, Condensed
OAR 918-282-0170(3)(c) lists 15 related-training subjects for the equivalent-training entry route to this license. These are preparation curriculum, not a published examination blueprint. No percentage allocation, question count per subject, or "highest-weighted area" has been publicly verified, so do not trust any source that claims exact weights. The complete walkthrough is in the OR-JE Exam Domains guide; the condensed version follows.
Math, Fundamentals and Measurement (Domains 1, 6, 7)
Electrical mathematics; electrical fundamentals and basic theory, including AC and DC; and electrical measuring devices.
- Be fluent with Ohm's law relationships and series/parallel reasoning.
- Know what common meters measure and how they are connected.
- Practice arithmetic until a silent calculator is a confirmation tool, not a crutch.
Safety, Tools and Plans (Domains 2, 3, 4)
Safety and accident prevention; care and use of hand and power tools; blueprint reading and electrical symbols.
- Recognize standard electrical symbols quickly.
- Know safe practice concepts that overlap with Oregon rule and law.
Code and Wiring Methods (Domains 5, 8, 9, 13)
Introduction to the National Electrical Code; wiring methods; low voltage and limited energy circuits; lighting circuits.
- These are the subjects where your tabbed NEC does the most work.
- Practice navigating Chapter 3 wiring methods and the Chapter 7 and 8 style special-circuit material quickly.
- Know where Oregon amendments modify the national text.
Calculations and Equipment (Domains 10, 11, 15)
Residential, industrial and commercial calculations; motors, generators and transformers; high voltage distribution and equipment.
- Load calculations reward a repeatable, written method.
- Motor and transformer questions combine code tables with theory.
Sketching and Electronics (Domains 12, 14)
Practical circuit sketching and fundamentals of electronics.
- Sketching is a curriculum subject, but no separately timed practical assessment was verified for the exam itself, so do not assume a drawing station.
- Do not assume it is absent from written items either; be able to read and reason about circuit diagrams.
One more caution: the rule requires a C or better in graded classes or a pass in ungraded classes for the equivalent-training route. That is a transcript requirement for eligibility, not an exam scoring rule.
Eligibility Numbers to Memorize
The baseline is a high-school diploma, GED, or accepted equivalent, plus an approved Oregon apprenticeship or an accepted equivalent route. BCD form 440-2570I describes the outside-Oregon routes:
| Route | Classroom | On-the-job hours | Category minimums |
|---|---|---|---|
| Education plus experience | 576 hours | 8,000 qualifying hours | At least 1,000 each in residential, commercial, industrial |
| Experience only | None required | 16,000 qualifying hours | At least 2,000 each in residential, commercial, industrial |
Training and work-experience hours are qualification requirements, not exam durations. The full qualification pathway is explained in OR-JE Requirements: Eligibility, Prerequisites and How to Qualify.
J Versus Supervising, Plant and Limited Licenses
The J license is its own credential with its own exam. Several mistakes come from blending it with neighbors:
- General Supervising Electrician: a different examination. Do not borrow its pass rate, fees, or study scope.
- Plant Journeyman: a separate credential and exam.
- Limited journeyman licenses: narrower credentials with their own paths.
If you are weighing whether the credential pays off, the sourced discussion lives in OR-JE Salary Guide and Is the OR-JE Certification Worth It?. For the employer side, see OR-JE Jobs.
Renewal and Continuing Education
- Three-year cycle, expiring October 1.
- Next listed J renewal: October 1, 2027.
- Renewal fee: $100.
- 24 approved CE hours.
The retained issuer-table breakdown for J is four hours of Oregon rule and law, eight hours of code-change, and twelve hours of code-related coursework. The four-hour rule-and-law course is corroborated by BCD's Oregon Rule & Law for Electricians document, and the Chapter 918 rule index points to eight code-change hours for General Journeyman Electricians. However, the current CE page's table could not be re-retrieved in full, so confirm category credit against your current BCD renewal record. Do not assume that any 24 hours qualify, and do not substitute another Oregon license's CE requirements for yours.
A Domain-Ordered Review Sequence
Because the exam is open-book, sequence your review around building a fast, accurate reference workflow, not memorizing. Here is one ordering tied to this exam's subjects. It is an editorial suggestion, not an official weighting.
Math, theory, measurement
- Electrical mathematics, AC/DC fundamentals, measuring devices (Domains 1, 6, 7).
- Why first: every later calculation depends on this foundation.
Code navigation
- Introduction to the NEC, wiring methods, lighting, low voltage and limited energy (Domains 5, 8, 9, 13).
- Tab your confirmed references; add Oregon amendment cross-references only as your current instructions allow.
Calculations and equipment
- Residential, industrial and commercial calculations; motors, generators, transformers; high voltage distribution (Domains 10, 11, 15).
- Time yourself using only approved references and a silent calculator.
Safety, plans, sketching, electronics, Oregon law
- Safety, tools, blueprint symbols, circuit sketching, electronics (Domains 2, 3, 4, 12, 14), plus ORS 479 and OAR 918 look-ups.
- Finish with full-length timed runs of 52 questions in three hours at the main practice test site.
For a sense of where candidates typically struggle, read How Hard Is the OR-JE Exam?. Keep in mind that practice exams and class-preparation materials are not permitted in the exam room, so rehearse with them at home and bring only approved references.
Frequently Asked Questions
The Oregon Secretary of State License Directory lists 52 questions with a three-hour limit. The exam is written and open-book. A scored versus unscored split and the exact mix of item types were not verified.
BCD specifies a 75% passing threshold. Results are mailed, generally within two weeks. See OR-JE Passing Score for more detail.
You must test within 60 days of the date on your authorization letter. Submit your experience and education documentation for approval before arranging the exam.
Wait 30 days and reapply before another authorized attempt. Use the interval to revisit weak areas and tighten your reference tabbing within whatever annotation rules your current BCD instructions allow.
It depends on which BCD document version applies. The 2019-dated rendering allows tabs and margin notes generally, while the text marked revised September 2026 permits tabs and highlighting but limits margin notes to cross-references and state or local amendments, and excludes calculation examples and additional pages. Confirm against your Letter of Authorization before marking anything.
Once your approved references are tabbed and your calculation method is reliable, put the whole routine under realistic time pressure at the OR-JE Exam Prep practice test before your authorization window closes.
