About the Tennessee Contractor Combined Residential and Small Commercial Con… Exam

The practice material draws on tasks that require interpreting site conditions and responding before work proceeds. Questions ask you to recognize when a concrete mix does not match the approved specification, identify the need to assess a wall before removing it, and understand how flashing and layered building wrap help manage water. Other scenarios address roof framing, compacted fill placed in lifts, and confirming permit requirements. Safety-related items involve circular-saw use, respirator preparation, and communicating hazards or restricted work areas among subcontractors. Working through these examples can sharpen your ability to connect construction details with sequencing, coordination, and risk control on residential and small commercial jobs.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

A concrete delivery ticket shows a mix different from the approved mix specified for the work. What is the prudent action before placement?

  1. AAdd water on site until the mix appears workable
  2. BPlace the concrete quickly before it begins to stiffen
  3. CHold placement and resolve the discrepancy with the responsible project representative or supplier
  4. DUse the concrete only in the most heavily reinforced area
Show answerCorrect answer: C

A mix discrepancy can affect strength, durability, or placement performance. The contractor should pause and obtain an authorized resolution rather than alter or place the mix without approval.

Question 2

A contractor plans to remove part of an interior wall but is unsure whether it supports the roof or floor above. What should be done before demolition?

  1. ARemove a small section and observe whether the ceiling moves
  2. BDetermine the wall's structural role and provide an approved support plan if it is load-bearing
  3. CProceed if the wall has no plumbing fixtures
  4. DCut the wall studs one at a time to reduce vibration
Show answerCorrect answer: B

A wall may carry loads even when its function is not obvious. Its structural role should be established before removal, and any required temporary support and replacement framing should be planned appropriately.

Question 3

What is the purpose of flashing where a roof meets a vertical wall?

  1. ATo direct water away from the joint and onto the drainage surface
  2. BTo increase the roof framing's load capacity
  3. CTo provide ventilation to the attic
  4. DTo bond roof sheathing to the wall framing
Show answerCorrect answer: A

Flashing manages water at vulnerable intersections by directing it onto the roof drainage plane rather than allowing it to enter the wall or roof assembly.

Question 4

During a roof framing review, what is the main function of collar ties installed high between opposing rafters?

  1. ATo resist separation of the rafter pair near the ridge under uplift forces
  2. BTo provide a continuous bearing surface for roof sheathing
  3. CTo replace the need for ceiling joists in every roof design
  4. DTo support the exterior wall sheathing at the eaves
Show answerCorrect answer: A

Collar ties help connect opposing rafters in the upper portion of the roof and resist their separation, particularly under uplift. They do not automatically replace other structural members; design requirements depend on the roof system.

Question 5

When installing a water-resistant exterior wall assembly, why is it important to lap the upper layer of building wrap over the lower layer?

  1. ATo direct incidental water down and outward across the drainage plane
  2. BTo hold wall insulation in place without fasteners
  3. CTo prevent all water vapor from passing through the wall
  4. DTo make the sheathing joints structurally stronger
Show answerCorrect answer: A

Shingle-style laps help water drain toward the exterior rather than being directed behind the lower layer. Building wrap is part of a water-management strategy, not a substitute for all flashing or moisture-control details.

Question 6

When cutting lumber with a circular saw, which action is a sound basic safety practice?

  1. ADisable the blade guard if it slows the cut
  2. BSupport the work so the kerf will not pinch the blade
  3. CHold the workpiece by hand as close as possible to the blade
  4. DSet the blade depth much deeper than the material
Show answerCorrect answer: B

Properly supporting the stock helps prevent the cut from closing on and binding the blade, which can cause kickback. Guards should remain functional, and hands should be kept clear of the cutting path.

Question 7

A contractor is preparing to operate a jobsite with several subcontractors. Which practice most directly helps communicate changing site hazards and work-area restrictions?

  1. AHold regular coordination briefings and share relevant site-safety information with affected crews
  2. BTell only the first subcontractor on site and rely on word of mouth thereafter
  3. CPost a general safety sign at the entrance and avoid further updates
  4. DWait until an incident occurs before discussing new hazards
Show answerCorrect answer: A

Regular coordination briefings help affected workers understand current hazards, access limits, and changes in work areas. A sign or informal word of mouth alone may not reach everyone who needs the information.

How to use this practice test

Access is free. A practice session presents up to 20 random questions from the 50-question bank, then shows your results. Use the explanations or missed items, where available, to identify which construction decisions need further review, such as framing, weatherproofing, site preparation, permits, or safety.

Preparation tips

  • Compare concrete delivery information with the specified mix before deciding whether placement should proceed.
  • Review how flashing and shingle-style laps in building wrap direct water toward the exterior rather than into wall assemblies.
  • Practice identifying when a wall's structural role must be determined before demolition begins.
  • Refresh jobsite procedures for compacting fill in lifts, communicating changing hazards, and preparing a worker for required respirator use.
  • Check how local building officials determine permit requirements for a planned scope of work.
