Idaho Public Works Contractor Exam — Practice Test Guide

What This Practice Exam Covers

The Idaho Public Works Contractor Exam is a 100-question, 240-minute test administered by the Division of Occupational and Professional Licenses (DOPL). You must score 70% or higher — answering at least 70 questions correctly — to pass.

This site offers two ways to prepare:

• Free practice exam: Each attempt gives you 10 questions pulled from a limited question pool. You can retake it as many times as you like to get familiar with the question format, wording style, and subject matter before committing to full prep.
• Full practice exam (paid): A complete 100-question exam with a 240-minute time limit, matching the real exam's structure exactly. Questions are drawn from a pool of 490+ items, so every attempt presents a different set — no two sessions are identical. Every question ties directly to the official exam topic list.

Start with the free exam to calibrate where you stand. Use the full exam for serious, repeated practice.

What You'll Be Tested On

The exam draws from 13 topic areas. Item counts reflect the real exam's weighting.

Sections 1–4 (Business Foundations) — 7 items total
These sections cover starting and organizing a construction business in Idaho. Expect questions on the components of a business plan (executive summary, financial plan, management and operations plans, marketing plan elements), the types of professional advisors a contractor should select (CPA/LPA, attorney, insurance agent, banker), and Idaho business entity types. You must know the liability characteristics of sole proprietorships, partnerships, LLCs, and corporations; LLC naming and formation requirements; S corp vs. C corp tax treatment differences; and how foreign entities register with the Idaho Secretary of State. Section 4 also tests DOPL's regulatory mission and the consequences of performing public works without a required license.

Section 5 (Accounting and Finance) — 20 items
The single heaviest section. Questions test financial statements (balance sheet, income statement, cash flow statement), cash vs. accrual accounting, and when each method applies. You must be able to apply the percentage of completion method and the completed contract method of revenue recognition — including when each is required and what conditions trigger each. Financial ratios get serious attention: know the formulas and interpretation of liquidity, efficiency (including inventory ratio), leverage/safety, and profitability ratios. Depreciation questions cover straight-line, MACRS, and the IRS Section 179 deduction. Cash management questions test what legally counts as "cash" and the mechanics of positive vs. negative cash flow.

Section 6 (Employment Law) — 20 items
Tied with Section 5 as the heaviest area. Federal anti-discrimination laws tested include Title VII, ADEA, ADA, Equal Pay Act, GINA, and the Pregnancy Discrimination Act — including employee thresholds that trigger each law. The ADA's reasonable accommodation and undue hardship standards appear regularly. FLSA questions focus on overtime rates, exemptions (including the computer professional exemption), and recordkeeping. Federal contractor obligations are heavily tested: Davis-Bacon prevailing wage rules, the Copeland Anti-Kickback Act's weekly certified payroll requirements, CWHSSA overtime standards, Walsh-Healey Public Contracts Act, and the McNamara-O'Hara Service Contract Act. Idaho-specific rules tested include wage payment statutes (§§45-608 through 45-613), new hire reporting (including W-4 process and electronic reporting), child labor, and employer recordkeeping requirements.

Section 7 (Insurance and Bonding) — 20 items
Another 20-item section covering insurance types (general liability, builder's risk, automobile, completed operations, contractors pollution liability), Idaho workers' compensation rules, and unemployment insurance (UI) employer obligations. Know the corporate officer exemption and casual employment exemption for workers' comp. UI questions test experience rating, new employer standard rates, reportable vs. nonreportable wages (tips, 401(k), cafeteria plans, disability pay), and penalty provisions for late filing or payment. Surety bond questions distinguish bid bonds, performance bonds, and payment bonds. The Miller Act — which mandates both performance and payment bonds on federal public works contracts — is specifically tested.

Section 8 (Estimating and Bidding) — 7 items
Tests conceptual, preliminary, and detailed estimate types; the quantity survey/takeoff process; and how labor, materials, equipment, subcontractors, and general overhead are priced. Know the difference between project overhead and general overhead, and how contingency and allowance amounts are built into a summary total.

Section 9 (Contracts) — 8 items
Elements of a valid contract, contract types (lump sum, unit price, cost plus, time and materials, incentive, guaranteed maximum), and the Statute of Frauds written-agreement requirements. Idaho's retention proceeds limits and release requirements are tested directly. Know breach of contract definitions and available remedies, and what the optional elements of a construction contract include.

Section 10 (Project Management) — 10 items
Five project management phases: initiation, planning, executing, monitoring/controlling, and closing. CPM (Critical Path Method) questions require you to identify the critical path and calculate float/slack, earliest start, and latest start dates. Gantt chart reading is also tested. Know the roles of the owner's representative, CM/PM, superintendent, foreman, and expediter. Cost control questions involve CSI cost codes, variance detection, and inventory control.

Section 11 (OSHA and Safety) — 5 items
OSHA recordkeeping forms (300, 300A, 301), the 10-or-fewer-employee exemption from routine recordkeeping, and the distinction between recordable and non-recordable injuries. Reporting timelines for fatalities and multiple hospitalizations are tested. Know the OSHA voluntary programs: VPP, SHARP, OSHA Challenge, Alliance, and Strategic Partnership.

Section 12 (Taxes) — 1 item
One question, but it could land anywhere: Idaho sales and use tax for contractors, independent contractor vs. employee classification using the right-to-control test, Form 1099-MISC obligations, withholding forms, or tax recordkeeping periods.
Sources: Idaho Tax Commission Brochure #40 Contractors; Contractor's Business and Law Reference Manual, Section 12

Section 13 (Mechanic's Liens) — 2 items
Who can file, the 90-day filing deadline, required claim contents, lien priority when proceeds are insufficient, the 6-month enforcement deadline, releasing a lien by posting a surety bond, and general contractor disclosure requirements for residential lien notices.

Worked Sample Questions

Question 1
Which of the following is considered "cash" for purposes of cash management?

• A. Accounts receivable and prepaid expenses
• B. Currency, coins on hand, bank balances, and negotiable money orders and checks
• C. Inventory on hand and accounts receivable
• D. Property, equipment, and tools

Correct Answer: B

Cash has a specific legal and accounting definition. Accounts receivable is money owed to you but not yet collected — it is not cash. Inventory, equipment, and prepaid expenses are assets, but not liquid cash. Only currency, coins, actual bank balances, and negotiable instruments (money orders and checks you can deposit) meet the definition. This distinction matters because cash flow problems kill contractors who confuse "billable work" with "money in hand."

Question 2
Under the Fair Labor Standards Act, at what rate must covered, non-exempt employees be paid for hours worked over 40 in a workweek?

• A. Time and one-half their regular rate of pay
• B. Their regular rate of pay
• C. Double their regular rate of pay
• D. Time and one-quarter their regular rate of pay

Correct Answer: A

The FLSA is unambiguous: overtime for non-exempt covered employees is 1.5 times the regular rate — not straight time, not double time. Double-time pay is required under some state laws and union agreements, but not by the FLSA itself. Watch for distractors using "double" or "time and one-quarter."

Question 3
For Idaho unemployment insurance purposes, the fact that a worker is paid on a commission or piecework basis is sufficient evidence to classify that worker as an independent contractor. True or False?

Correct Answer: FALSE

Method of payment — whether hourly, salary, commission, or piecework — does not control independent contractor classification for UI purposes. Idaho UI law looks at the totality of the working relationship. A worker paid per piece can still be a covered employee if the employer controls how the work is performed. Assuming otherwise is an expensive mistake.

How to Read Your Score

The passing threshold is 70% — 70 correct answers out of 100. Treat your first practice attempt as a diagnostic, not a verdict. Most candidates score below passing on their first full attempt; that result tells you which of the 13 sections need focused attention, not whether you will pass the real exam.

Use the section-by-section breakdown after each attempt strategically. If you score below 70% in Section 5 (Accounting and Finance) or Section 6 (Employment Law), those two areas alone represent 40 of the 100 exam questions — getting them wrong at a high rate is enough to fail even if you ace everything else. Similarly, Section 7 (Insurance and Bonding) is another 20-item block that rewards systematic study.

Scoring between 70% and 79% on practice should be read as "in range but not safe." A single bad day — misread questions, unfamiliar phrasing — can erase a thin margin. Most candidates who pass confidently score 80%+ on repeated practice attempts before sitting for the real exam.

The free exam is a useful first look at question style. The full 490+ question pool gives you the variety needed to stop pattern-matching and start genuinely understanding the material.

Where Candidates Lose Points

Confusing financial ratios. Section 5 asks for specific ratio formulas. Candidates who know ratios exist but cannot distinguish a liquidity ratio from a leverage/safety ratio, or who miscalculate the working capital ratio, drop multiple points in one topic area.

Employee threshold errors. Section 6 tests different headcount thresholds for different federal laws. Getting the ADA threshold mixed up with the Title VII threshold — or forgetting the ADEA's separate threshold — is a common single-point loss that repeats across multiple questions.

Miller Act scope. Section 7 candidates often know surety bonds exist but cannot distinguish when the Miller Act applies (federal public works) from state-level bonding requirements, or confuse performance bond obligations with payment bond obligations.

Copeland Anti-Kickback details. The weekly certified payroll statement requirement under the Copeland Anti-Kickback Act is tested precisely. Vague knowledge of "prevailing wage" rules is not enough.

CPM float calculations. Section 10 questions on Critical Path Method require actual arithmetic — earliest start, latest start, and float. Candidates who understand the concept but skip the calculation step lose these points.

Idaho retention limits. Section 9 tests specific Idaho statutory rules on retention proceeds. Candidates who know general contract law but have not read the Idaho-specific statutes consistently miss these.

OSHA recordkeeping form distinctions. Knowing that Forms 300, 300A, and 301 exist is not sufficient — the exam tests what each form records, when the 10-employee exemption applies, and what the reporting deadlines are for fatalities.
