Idaho Public Works Contractor Practice Exam

What This Practice Exam Covers

The Idaho Public Works Contractor Exam is a 100-question, 240-minute licensing exam with a passing score of 70%. It tests knowledge across 13 topic areas drawn from the Contractor's Business and Law Reference Manual, covering everything from financial statements and employment law to bonding, project scheduling, and mechanics' liens.

This practice exam gives you two ways to prepare:

• Free practice exam: 10 questions per attempt, pulled from a limited question pool. You can retake it as many times as you want to get comfortable with the format and question style — a useful starting point before committing to deeper study.
• Full practice exam (paid): Mirrors the real exam exactly — 100 questions, 240-minute time limit. Questions are drawn from a pool of 0+ items, so each attempt delivers a unique set. No two practice exams are identical. Questions are built directly from the official topic and subtopic list provided by the test authority.

Start with the free exam to take your baseline, then use the full practice exam for realistic timed rehearsal.

What You'll Be Tested On

The exam weights its 13 sections unevenly. Knowing which sections carry the most questions is itself part of exam strategy.

Sections 5, 6, and 7 together account for 60 of the 100 questions. These are the sections where the exam is won or lost.

Section 5 — Financial Management (20 items)
Expect calculations. You need to read a balance sheet and income statement, compute financial ratios (current ratio, debt-to-equity, accounts receivable turnover, net profit margin), and distinguish cash-basis from accrual-basis accounting. Revenue recognition is tested directly — know the difference between the percentage-of-completion method and the completed-contract method and when each applies. Depreciation questions ask you to calculate straight-line depreciation and understand how MACRS differs. Cash flow questions may ask you to identify whether a scenario represents positive or negative cash flow and what corrective action is appropriate.

Section 6 — Employment and Labor Law (20 items)
This section tests specific federal statutes by name and threshold. You must know which anti-discrimination laws apply at which employee counts — the Age Discrimination in Employment Act, Americans with Disabilities Act, Title VII, Equal Pay Act, GINA, and the Pregnancy Discrimination Act each have distinct applicability rules. Federal contractor obligations are heavily tested: Davis-Bacon prevailing wage requirements, the Copeland Anti-Kickback Act, the Contract Work Hours and Safety Standards Act, Walsh-Healey, the Service Contract Act, and Executive Order 11246 on equal employment. Idaho-specific rules on wage payment timing, new hire reporting deadlines, child labor restrictions, and recordkeeping are also fair game.

Section 7 — Insurance and Bonding (20 items)
Know the difference between general liability, builder's risk, completed operations, and commercial auto coverage — and what each one does and does not cover. Idaho workers' compensation requirements and the employer's obligations are tested. Surety bonds are a major subtopic: bid bonds, performance bonds, and payment bonds each have a distinct purpose and trigger. The Miller Act is tested specifically for federal public works projects — know the bond thresholds and the rights it extends to subcontractors and suppliers.

Section 10 — Project Management (10 items)
CPM calculations are the hardest questions in this section. You need to identify the critical path, calculate float/slack time, and determine earliest and latest start and finish dates for individual activities. Gantt chart interpretation, the five project phases (initiation, planning, executing, monitoring/controlling, closing), and the roles of the superintendent, foreman, owner's representative, and project expediter are all testable. Cost control questions reference CSI cost codes and variance detection.

Section 9 — Contracts (8 items)
Know the elements required to form a valid contract, the difference between lump-sum, cost-plus, and time-and-materials contracts, and what the Statute of Frauds requires in writing. Idaho's retention limits and release timeline are tested — know the maximum retention percentage and the conditions under which it must be released.

Section 8 — Estimating (7 items)
Expect questions on the difference between conceptual, preliminary, and detailed estimates, and when each is appropriate. Quantity survey and takeoff questions may involve unit conversions. Know how project overhead differs from general overhead, and how contingencies and allowances are applied.

Section 11 — Safety and OSHA (5 items)
OSHA recordkeeping is the most-tested subtopic here. Know which forms are required (300, 300A, 301), which injuries are recordable versus non-recordable, and the reporting deadlines for fatalities and hospitalizations. Understand the difference between the Construction Safety Act and the OSH Act, and be familiar with OSHA's voluntary programs by name.

Sections 3 and 13 — Business Structures and Liens (2 items each)
Section 3 tests the liability and tax characteristics of sole proprietorships, partnerships, LLCs, and corporations, including the S corp vs. C corp distinction and Idaho Secretary of State filing requirements. Section 13 focuses on Idaho mechanics' and materialmen's lien rules: the 90-day filing deadline, what the claim must contain, the 6-month enforcement window, lien priority, and how a general contractor can release a lien by posting a surety bond.

Sections 2 and 4 (2 items each), Sections 1 and 12 (1 item each)
These sections cover business planning, selecting professional advisors, DOPL licensing requirements, and Idaho tax obligations. Low item counts mean you can earn these points with focused reading rather than deep study.

How to Read Your Score

The passing score is 70%, meaning you need 70 correct answers out of 100. On a practice exam, your score tells you where you stand — but treat a first attempt as a diagnostic, not a verdict.

Most candidates score lower on their first full practice attempt than they expect, because the exam mixes calculation-heavy financial questions with statute-specific employment law and procedural lien rules. A first-attempt score in the low 60s is common and recoverable. A score below 60% typically means at least one of the three heavy sections (Sections 5, 6, or 7) needs significant work.

Use the topic-by-topic breakdown to direct your time. If you're scoring well on Section 10 project management but missing Section 6 employment law questions, reading about CPM will not help your score. Focus where the item counts are highest and your accuracy is lowest.

Scoring 70–74% on practice should not be read as exam-ready. The real exam will include questions you haven't seen before, and a three- to five-point cushion on practice is a reasonable target before sitting for the actual exam. Scoring above 80% consistently across multiple full practice attempts is a reliable indicator of readiness.

Where Candidates Lose Points

Section 5 ratio calculations: Candidates plug numbers into the wrong formula or invert a ratio. Current ratio and quick ratio are frequently confused. Know exactly which assets and liabilities belong in each calculation.

Section 6 employee thresholds: Many candidates know the law but not the specific employee count at which it applies. The ADEA, ADA, and Title VII have different thresholds. One wrong threshold means a wrong answer.

Section 6 federal contractor rules: Davis-Bacon, the Copeland Anti-Kickback Act, CWHSSA, and the Service Contract Act are each triggered by different contract types and dollar amounts. Candidates who blur these together lose multiple points.

Section 7 Miller Act details: Candidates confuse the bond amounts, who is protected, and the deadlines subcontractors must meet to preserve their rights. These are precise statutory rules — approximations cost points.

Section 9 retention: Idaho's retention rules have specific numerical limits and timing requirements. Candidates who know the concept but not the specific threshold get these questions wrong.

Section 10 CPM math: Float calculations require working through both a forward pass and a backward pass. Candidates who skip the backward pass miscalculate late start dates and misidentify the critical path.

Time pressure on Section 5: Financial ratio and depreciation questions take longer than law-recall questions. Candidates who don't pace themselves sometimes run short on time in the final 20 questions.
