Which item does the CSLB's C-6 definition name among the products a cabinet, millwork and finish carpentry contractor makes?
- a.Sashes✓
- b.Structural headers
- c.Roof trusses
- d.Exterior stair stringers
The C-6 definition lists cabinets, cases, sashes, doors, trims and nonbearing partitions. Roof trusses and structural headers are framing work, and exterior staircases are named in the C-5 framing and rough carpentry classification.Cal. Code Regs. tit. 16 §832.06 (C-6 classification, CSLB)

- c.Installs the plumbing fixtures set in them
- d.Places, erects and finishes them in structures✓
The definition says the C-6 contractor also places, erects and finishes such cabinets and millwork in structures. Structural design is not part of the classification; plumbing fixtures and electrical wiring belong to the plumbing and electrical trades.Cal. Code Regs. tit. 16 §832.06 (C-6 classification, CSLB)

- a.The cabinet crown moulding
- b.The overhead garage door✓
- c.The kitchen wall cabinets
- d.The kitchen base cabinets
The C-5 definition lists overhead doors among framing and rough carpentry items. Base and wall cabinets and the crown moulding on them are finish carpentry and millwork described in the C-6 definition.Cal. Code Regs. tit. 16 §832.05 (C-5 classification, CSLB)

A carpenter with no employees wants to install a $700 shelf unit that needs no building permit and does not advertise as licensed. What does the CSLB say?
- a.A license is required if the work takes more than a day
- b.No license is required for this job✓
- c.A license is required because shelves are millwork
- d.A license is required for cabinet work
The CSLB allows unlicensed work only where no permit is required, no employee labor is used and the total of labor, materials and other costs is less than $1,000, and the person does not advertise as licensed. This job meets those conditions; the type of work and the time it takes are not the test.CSLB, Before Applying for the Examination (licensing exemptions)

- b.Splitting is allowed with separate payments
- c.Larger projects may not be split to avoid licensing✓
- d.Splitting is allowed if no permit is pulled
The CSLB states that work on a larger project may not be broken down into amounts of less than $1,000 to meet the exemption. Separate invoices, separate payments or the lack of a permit do not change the project's total value.CSLB, Before Applying for the Examination (licensing exemptions)
A federal guide specification for laminate casework lists the quality categories in the industry's architectural woodwork standards. Which grade does it describe as appropriate only under severe funding limitations?
- a.Premium grade
- b.Economy grade✓
- c.Select grade
- d.Custom grade
The guide specification says the casework quality standards list premium, custom and economy grades, recommends custom or premium, and limits economy grade to severe funding limitations. Select is not one of the three casework grades.UFGS 06 41 16.00 10 (casework quality standards)
Before final shop drawing approval, a federal casework project requires a full-size sample unit with at least one door and one drawer. What is that sample called?
- a.A submittal schedule
- b.A product data sheet
- c.A shop drawing
- d.A mock-up✓
The guide specification calls for a full-size mock-up of a typical unit, with at least one door and one drawer assembly, before final shop drawing approval. A submittal schedule is a list, a product data sheet describes a product, and a shop drawing is a drawing, not a built unit.UFGS 06 41 16.00 10 (submittals)
Which dimensions describe one board foot of lumber?
- a.12 by 1 by 1 feet, or its cubic equivalent
- b.12 by 12 by 12 inches, or its cubic equivalent
- c.1 by 1 by 12 inches, or its cubic equivalent
- d.12 by 12 by 1 inches, or its cubic equivalent✓
The Wood Handbook defines a board foot as a board 12 inches long, 12 inches wide and 1 inch thick, or its cubic equivalent (144 cubic inches). A 12-inch cube is a cubic foot; 1 by 1 by 12 inches is only 12 cubic inches; and 12 by 1 by 1 feet is 12 cubic feet.Wood Handbook (FPL-GTR-282), board foot definition
How many board feet are in one piece of 4/4 hard maple 9 inches wide and 12 feet long?
- a.9 board feet✓
- b.12 board feet
- c.7.5 board feet
- d.108 board feet
Board feet equal thickness times width in inches times length in feet, divided by 12: 1 × 9 × 12 ÷ 12 = 9. Twelve board feet uses the length alone; 108 forgets to divide by 12; and 7.5 treats the board as 10 feet long.Wood Handbook (FPL-GTR-282), board foot definition
A cut list has eight pieces of 1-inch stock, each 3 inches wide and 48 inches long. What is the net board footage?
- a.1 board foot
- b.96 board feet
- c.12 board feet
- d.8 board feet✓
Each piece is 1 × 3 × 48 = 144 cubic inches, which is exactly 1 board foot, so eight pieces are 8 board feet. One board foot counts a single piece; 96 forgets to divide by 12 after converting the length to feet (1 × 3 × 4 × 8); and 12 confuses the count.Wood Handbook (FPL-GTR-282), board foot definition
A shop prices a job at $9,600 of cost with a 25 percent markup. What is the selling price?
- a.$11,520
- b.$12,800
- c.$9,625
- d.$12,000✓
Markup is a percentage of cost: 9,600 × 1.25 = $12,000. $12,800 is cost divided by 0.75, which produces a 25 percent margin rather than markup; $11,520 is a 20 percent markup; and $9,625 adds $25 instead of 25 percent.Business estimating arithmetic (markup on cost)
A cabinet job's cost is $15,000. What selling price gives a 40 percent gross margin on the price?
- a.$21,000
- b.$15,600
- c.$25,000✓
- d.$22,500
Price equals cost divided by one minus the margin: 15,000 ÷ 0.60 = $25,000, leaving $10,000, or 40 percent of price. $21,000 is a 40 percent markup on cost, about a 29 percent margin; $15,600 adds 4 percent; and $22,500 is a 50 percent markup, a 33 percent margin.Business estimating arithmetic (margin on price)
An estimator needs 140 linear feet of base moulding installed and adds 15 percent for miters, cuts and defects. How much should be ordered?
- a.165 linear feet
- b.161 linear feet✓
- c.210 linear feet
- d.155 linear feet
Gross equals net times one plus waste: 140 × 1.15 = 161 linear feet. One hundred fifty-five adds only 15 feet; 165 divides 140 by 0.85, treating 15 percent as a yield loss; and 210 is a 50 percent allowance.Estimating arithmetic (waste factor)
Each 4 × 8 sheet of melamine yields five cabinet bottoms after kerfs and trimming. How many sheets are needed for 23 base cabinets with one bottom each?
- a.6 sheets
- b.5 sheets✓
- c.4 sheets
- d.23 sheets
Twenty-three bottoms at five per sheet needs 4.6 sheets, which rounds up to 5 because partial sheets cannot be bought. Four sheets yield only 20 bottoms; 6 sheets is one more than needed; and 23 sheets treats each bottom as a full sheet.Estimating arithmetic (sheet goods)
According to the Wood Handbook's recommended values, what average moisture content suits interior woodwork in the dry southwestern United States?
- a.About 15 percent
- b.About 11 percent
- c.About 6 percent✓
- d.About 8 percent
The Wood Handbook recommends an average of about 6 percent (4 to 9 percent for individual pieces) for interior woodwork in the dry southwestern area. Eight percent is the figure for most of the United States, 11 percent for damp, warm coastal areas, and 15 percent is too wet for interior woodwork.Wood Handbook (FPL-GTR-282), recommended moisture content
Which federal formaldehyde emission standard applies to hardwood plywood with a veneer or composite core?
- a.0.13 ppm
- b.0.11 ppm
- c.0.09 ppm
- d.0.05 ppm✓
The federal rule sets 0.05 ppm for hardwood plywood with a veneer or composite core. The 0.09 ppm limit is for particleboard, 0.11 ppm for medium-density fiberboard and 0.13 ppm for thin MDF.40 CFR §770.10 (TSCA Title VI emission standards)
A California cabinet buyer sees only a "TSCA Title VI compliant" label on new vanity cabinets. What does CARB say about that label?
- a.California rejects products without a CARB-only label
- b.California accepts it in place of a CARB label✓
- c.California requires a separate state test certificate
- d.California limits it to exterior products
CARB states that California accepts products labeled only as TSCA Title VI compliant because the state and federal requirements are very similar. A CARB-only label or a separate state certificate is not required, and the acceptance is not limited to exterior products.CARB Composite Wood Products consumer FAQ
A California restaurant covered by Chapter 11B provides dining counters for customers. What portion of the seating and standing spaces at dining surfaces must comply with the accessible surface rules?
- a.At least 25 percent
- b.At least 10 percent
- c.At least 5 percent✓
- d.One per room
Chapter 11B requires at least 5 percent of the seating and standing spaces at dining surfaces to comply with the accessible dining and work surface section. Ten and 25 percent are not the stated figures, and one per room is not the rule.2025 CBC §11B-226.1 (dining and work surfaces)
What minimum clear floor space does Chapter 11B require in front of an accessible counter or appliance?
- a.30 by 48 inches✓
- b.30 by 30 inches
- c.36 by 60 inches
- d.24 by 36 inches
Chapter 11B sets the clear floor or ground space at 30 inches minimum by 48 inches minimum. Twenty-four by 36 and 30 by 30 inches are too small, and 36 by 60 inches exceeds the stated minimum.2025 CBC §11B-305.3 (clear floor space)
