Idaho Electrical Exam Overview

The Idaho Electrical Contractor / Limited Electrical Contractor exam is administered by PSI. Here are the key numbers:

• Passing score: 70 correct out of 100

Review the official exam bulletin for the full candidate handbook before your exam date.

Topics Covered on the Idaho Electrical Contractor Exam

The exam draws from 13 sections of the Contractor's Business and Law Reference Manual. Three sections carry the most weight and deserve the bulk of your preparation time:

• Section 5 — Financial Management (20 items): Bookkeeping, balance sheets, income statements, cash flow, financial ratios, and project accounting methods. This is one of the three highest-weighted sections.
• Section 6 — Employment Law (20 items): Federal anti-discrimination laws, FLSA wage and overtime rules, FMLA requirements, and Idaho-specific employment regulations. Twenty questions here — study it thoroughly.
• Section 7 — Insurance and Bonds (20 items): Types of contractor insurance, Idaho workers' compensation requirements, unemployment insurance, surety bonds, and independent contractor classification. The other 20-question section.

The remaining sections are lighter but still tested:

• Section 10 — Project Management (10 items): CPM scheduling, Gantt charts, float time, and scope/work breakdown structure
• Section 9 — Contracts (8 items): Contract types, Idaho retention statute, Statute of Frauds, and contract elements
• Section 8 — Estimating (7 items): Bid types, estimation methods, quantity takeoff, and pricing
• Section 11 — OSHA Recordkeeping (5 items): Forms 300/300A/301, reporting obligations, and exemptions
• Sections 2, 3, 4, 6, 13 (2 items each): Accounting professionals, business organizations, DOPL licensing, and mechanic's liens
• Sections 1 and 12 (1 item each): Business planning and tax obligations

Focus first on Sections 5, 6, and 7 — together they account for 60 of the 100 exam questions.

Study Materials

The Idaho Electrical Contractor exam is open book, so your reference manual preparation matters as much as your content knowledge.

Contractor's Business and Law Reference Manual
This is the only reference permitted in the exam room. You must download and print it yourself, then hole-punch it and place it in a three-ring loose-leaf binder before your exam date. Pre-exam highlighting, underlining, and permanent tab indexing are all permitted. No writing is allowed during the exam session, and temporary markers such as Post-its will be confiscated. Any candidate caught writing in their references or possessing unauthorized materials will have their binder seized and be reported to DOPL. Check the state licensing website for the current version of the manual.

Highlighters
Given that you can pre-mark your manual before exam day, strategic highlighting is one of the most practical preparation steps available. Sharpie Tank Highlighters are a reliable choice — the wide barrel and large ink supply hold up through a full manual, the chisel tip works for both underlining and broad highlighting, and the fluorescent ink resists smearing once dry. The 12-pack in assorted colors lets you color-code by section, which is particularly useful for the three heavy sections (5, 6, and 7).

Practice Exams
Our full practice exam matches the real test: 100 questions, 240-minute limit, same topic distribution. Questions are drawn from a pool of 490, so each attempt generates a different set. The score report breaks down your performance by section, which tells you exactly where to focus before your next attempt. Start with the free practice exam (10 questions, no account required), then move to the full version for complete exam simulation.

Study Tips for the Idaho Electrical Contractor Exam

Practice in the real format. Our practice exam mirrors the PSI exam — same question count, same time limit, same topic distribution. Candidates who complete full-length timed practice sessions arrive at the test center with accurate expectations of pacing and difficulty.

Prioritize by exam weight. Sections 5, 6, and 7 together account for 60 questions. Master those three sections before spending significant time on the 1- and 2-item sections.

Build a usable index in your manual. You have four hours for 100 questions — about 2.4 minutes per question. If you need to look something up, you need to find it in under 30 seconds. Tab and highlight your manual before exam day with that speed requirement in mind.

Trust your first instinct — with one exception. Go with your initial read on most questions. That said, changing an answer is appropriate when you have a concrete reason: you misread the question, or a later question clarified something. Reconsidering out of general anxiety rarely helps.

Eliminate before guessing. On any question where you're uncertain, rule out the options you know are wrong first. Narrowing four choices to two meaningfully improves your probability of a correct answer.
