WorkKeys Practice Questions (2026) — Free Sample Questions with Answers

Answer: A

1. Hours in 5 years: 2,000 × 5 = 10,000 hours.
2. Formula sheet: 1 kWh = 1,000 Wh. X: 6.2 kW × 10,000 h = 62,000 kWh × $0.14 = $8,680. Y: 3.5 kW × 10,000 h = 35,000 kWh × $0.14 = $4,900.
3. Totals: X = $18,400 + $8,680 = $27,080; Y = $21,900 + $4,900 = $26,800.
4. Difference: $27,080 − $26,800 = $280.00 (Model Y is cheaper).

$280.00: Correct. X: $18,400 + $8,680 = $27,080. Y: $21,900 + $4,900 = $26,800. Model Y costs $280.00 less.

$2,744.00: Counted only 1 year of electricity, which makes Model X look cheaper.

$3,500.00: Compared only the purchase prices.

$3,780.00: Compared only the electricity costs.

$7,280.00: Added the purchase-price difference to the electricity difference instead of letting them offset.

Compare total cost of ownership over the whole period: purchase price plus operating cost, with watts converted to kilowatts. Why this is a Level 7 item: a multi-step economic comparison with a unit conversion, where the cheaper purchase is not the better deal.

Answer: C

1. Radius = 6 ÷ 2 = 3 feet; use the liquid depth, 5 feet, as the height.
2. Formula sheet: cylinder volume = 3.14 × r² × h = 3.14 × 9 × 5 = 141.3 cubic feet.
3. Gallons: 141.3 × 7.48 ≈ 1,056.9, about 1,057 gallons.

141: This is the liquid volume in cubic feet; it was not converted to gallons.

352: Forgot to square the radius (3.14 × 3 × 5).

1,057: Correct. r = 3 ft; V = 3.14 × 3² × 5 = 141.3 cu ft; × 7.48 ≈ 1,057 gallons.

1,691: Used the 8-foot tank height instead of the 5-foot liquid depth; this is the full tank.

4,228: Used the 6-foot diameter as the radius.

For a partly filled tank, the "height" in V = 3.14 × r² × h is the liquid depth; halve the diameter, square it, and apply the given gallons-per-cubic-foot factor. Why this is a Level 7 item: cylinder volume from a diameter, implicit information (use the liquid depth, not the tank height), and a conversion factor given in the stem.

Answer: B

1. Area = length × width, so length = area ÷ width.
2. Break room length along the wall: 216 ÷ 12 = 18 feet.
3. Loading area: 60 − 22 − 18 = 20 feet.

18: This is the break room's length along the wall; you still have to subtract it and the office from 60 feet.

20: Correct. Break room length = 216 ÷ 12 = 18 ft; 60 − 22 − 18 = 20 ft.

32: Divided 216 by the 36-foot building depth instead of the 12-foot room depth.

38: Subtracted only the office and left out the break room.

42: Subtracted only the break room and left out the office.

When an area and one side are known, rearrange A = l × w to l = A ÷ w, using the side that actually belongs to that room. Why this is a Level 6 item: it requires rearranging the area formula, choosing the right dimension from a floor plan, and a further subtraction.

Answer: C

1. Treat the room as a 24 ft × 18 ft rectangle: 24 × 18 = 432 sq ft.
2. The missing corner is (24 − 14) = 10 ft wide by (18 − 10) = 8 ft deep: 10 × 8 = 80 sq ft.
3. Floor area = 432 − 80 = 352 sq ft.
4. 352 ÷ 20 = 17.6 boxes; round up to 18.

5: Used the perimeter (84 ft) instead of the area: 84 ÷ 20 = 4.2, rounded up to 5.

17: Rounded 17.6 down; 17 boxes cover only 340 square feet.

18: Correct. Area = 24 × 18 − 10 × 8 = 352 sq ft; 352 ÷ 20 = 17.6, so 18 boxes.

22: Used the full 24 × 18 rectangle (432 sq ft) without removing the missing corner.

26: Added the 10 × 8 corner (512 sq ft) instead of subtracting it.

Find an L-shaped area by splitting it into rectangles or by subtracting the missing corner, and find unlabeled sides from the labeled ones. Why this is a Level 5 item: several steps: finding missing side lengths, an area, a division and rounding up.

Answer: B

1. Change = amount paid − amount owed.
2. $50.00 − $17.36 = $32.64.
3. Check: $17.36 + $32.64 = $50.00.

$17.36: This is the order total, not the change; you still have to subtract it from $50.

$32.64: Correct. $50.00 − $17.36 = $32.64.

$33.64: Did not regroup a dollar for the cents: $50 − $17 = $33, then wrote $1.00 − $0.36 = $0.64 on top of it.

$47.36: Subtracted the smaller digit from the larger in each column instead of regrouping.

$67.36: Added the bill and the total instead of subtracting: $50 + $17.36 = $67.36.

Change is the amount paid minus the total; check it by adding the change back to the total. Why this is a Level 3 item: it is a single subtraction with the two amounts given in order and nothing extra.

Answer: B

Buyer earns a 3% credit for each PO that was not delivered: Deliveries affected by a properly noticed Force Majeure Event "are not Service Failures," so no credits are earned.

Not Service Failures, but Buyer may terminate on 30 days' notice: Correct. Supplier gave notice within 3 business days, so under Section 7 the missed deliveries are not Service Failures. Under Section 8.2, a Force Majeure Event lasting more than 45 consecutive days lets Buyer terminate on 30 days' written notice.

Buyer may terminate only after three Service Failures in two quarters: That is one ground for termination; Section 8.2 gives the 45-day Force Majeure ground separately.

Buyer may not terminate, because a flood is a Force Majeure Event: Section 8.2 lets Buyer terminate when a Force Majeure Event stops performance for more than 45 consecutive days.

Buyer must wait until the term ends and give notice of non-renewal: Non-renewal is one way out, but Section 8.2 allows earlier termination here.

In a contract, a conclusion reached under one section (no Service Failures) can still leave rights open under another (termination). Why this is a Level 7 item: dense contract prose in which the result of Section 7 must be combined with Section 8.2.

Answer: E

Discard the leaking carton, then place HOLD placards on the racks: Section 5 says staff "shall not discard product, even if it appears damaged, while a HOLD is in place."

Move the affected racks to Cold Room A to keep them cold: Placards are applied "without moving product," and held product may not be relocated.

Ask the shift lead to release the undamaged cartons for picking: Only QA may release product under HOLD.

Note the leak on the logger summary and return to picking: The logger summary is the shift lead's end-of-shift task, and held product may not be picked.

Fill out TE-1 and placard the rack, leaving the carton in place: Correct. Section 2 requires recording on Form TE-1 and placing a HOLD placard without moving product, and Section 5 bars discarding damaged product under HOLD.

The notice's general rule about held product (Section 5) applies even to a case it does not describe, such as a leak. Why this is a Level 6 item: a situation the notice never describes must be handled by applying principles from two sections.

Answer: A

A full refund minus a 15% restocking fee: Correct. Power tools may be returned within 60 days, so day 45 qualifies. Opened but unused and complete is Code B, which gets "a full refund minus a 15% restocking fee."

Store credit only: Store credit is for Code C items that are used, damaged, or missing parts; this drill is complete and unused.

A full refund with no fee: A full refund with no fee is for Code A (unopened) or DOA items; this drill was opened.

No refund, because the 30-day limit has passed: The 30-day limit is for most items; power tools have 60 days.

A full refund mailed as a check: Mailed checks are only for cash refunds over $200, and the restocking fee still applies to Code B.

Work through the conditions in order: is the item eligible, which code fits, and what refund goes with that code? Why this is a Level 5 item: a longer procedure with a defined acronym and if-then rules that must be applied to a new case.

Answer: B

Hold them in one hand and keep two feet and a hand on the ladder: This keeps three points of contact, but the policy says to carry tools in a tool belt or raise them with a hand line "rather than holding them in your hands while you climb."

Use a tool belt for the drill and a hand line for the fixture: Correct. The policy says to "carry tools in a tool belt or raise them with a hand line rather than holding them in your hands while you climb."

Set them on the top rung first, then climb up to them: The policy never mentions setting items on the ladder; it calls for a tool belt or a hand line.

Have a coworker hold the ladder and hand them up to you: The policy mentions a coworker only for standing guard near a doorway or aisle; it says to use a tool belt or a hand line.

Switch to a stepladder so you can hold them as you climb: The tool rule applies on any ladder; changing ladders does not let you climb with tools in your hands.

A policy can rule out a method that seems safe (three points of contact while holding tools); follow the method the policy names. Why this is a Level 4 item: a longer policy with several related rules; you must pick the rule that fits the changed task (carrying tools) over nearby ones that look similar.

Answer: A

Leave the building by the nearest exit: Correct. The notice says, "If an alarm sounds after 11:00 a.m., treat it as a real emergency and leave by the nearest exit." 11:30 a.m. is after the test period.

Call Facilities at extension 4410 to ask about it: Extension 4410 is for reporting an alarm you cannot hear, not for checking on an alarm.

Keep working until the all-clear announcement: The notice says to keep working only during the test period, which ends at 11:00 a.m.

Tell the visitors in your area that it is a test: Visitors are to be told about the test before 9:00 a.m.; an alarm at 11:30 a.m. is not part of the test.

Wait at your desk for directions from your supervisor: The notice never mentions waiting for a supervisor; it says to leave by the nearest exit.

Match the time in the question to the time limits in the notice before choosing an action. Why this is a Level 3 item: a short, direct notice; the answer is a clearly stated detail whose wording closely matches the text.

Answer: B

1. Pressure gauge: 5 marks between numbers 5 apart → 1 psi per mark; needle 1 mark past 20 = 21 psi → Caution.
2. Temperature gauge: 5 marks between numbers 50 apart → 10 °F per mark; needle 2 marks past 200 = 220 °F → Normal.
3. Different conditions → follow the more serious (Caution): reduce firing rate; log readings.

Take no action; log readings hourly: Temperature (220 °F) is Normal, but pressure (21 psi) is in the Caution range, and the more serious condition rules.

Reduce firing rate; log readings: Correct. The pressure needle is one mark past 20 (marks are 1 psi), so 21 psi, which is Caution (above 18 up to 24). Temperature is 220 °F (two 10° marks past 200), which is Normal. Follow the more serious condition: Caution.

Shut down burner; call supervisor: Shutdown needs pressure above 24 psi or temperature above 240 °F; the gauges read 21 psi and 220 °F.

Check feedwater and burner: This is the Low action; neither gauge is below its Low threshold.

Read each dial with its own mark value, classify each reading, then apply the chart's rule for combining them. Why this is a Level 6 item: two gauges with different scales plus a condition chart make a difficult graphic, used to make a decision.

Answer: D

The defect rate stays about the same at every line speed tested.: This is true only for the slower runs; the rate roughly triples above 60 ft/min.

The defect rate rises steadily across the whole range of speeds.: Partly right: the rate does rise at high speeds, but from 40 to 60 ft/min the points go up and down around 1.0–1.4% with no steady rise.

The defect rate falls steadily as the line speed is increased.: This reverses the pattern; the points on the right (faster runs) are the highest.

The defect rate is flat up to about 60 ft/min, then climbs.: Correct. From 40 to 60 ft/min the points stay between about 1.0% and 1.4%; above 60 ft/min each faster run has a higher rate, reaching about 4.4% at 95 ft/min.

Describe a scatter plot section by section; a pattern that holds only over part of the range should be stated that way. Why this is a Level 5 item: interpreting a trend that changes partway through a low-moderate graph.

Answer: A

1. 90% of each target: Line 1 180, Line 2 162, Line 3 171, Line 4 216.
2. Output below 90%: only Line 3 (160 < 171).
3. Scrap above 3.0%: only Line 2 (3.4%).
4. Flag Lines 2 and 3.

Lines 2 and 3: Correct. Line 2: scrap 3.4% > 3.0%. Line 3: 90% of 190 = 171, and output 160 < 171. Lines 1 and 4 pass both tests.

Lines 1, 2 and 3: Line 1's output (182) is above 90% of its target (180), and its scrap is 2.4%, so it is not flagged.

Lines 2, 3 and 4: Line 4's scrap (2.9%) is below 3.0%, and its output (225) is above 90% of 240 (216).

Line 3 only: Line 3 is flagged for output, but this misses Line 2, whose scrap (3.4%) is above 3.0%.

When a rule has an "or," check every tile against both conditions; one failure is enough to flag. Why this is a Level 5 item: a high-moderate dashboard (four tiles, several variables) used to make a decision.

Answer: B

1. Open routes to C: Depot–A–B–C and Depot–D–E–C (B–D is dashed = closed).
2. Depot–A–B–C = 4 + 3 + 4 = 11 miles.
3. Depot–D–E–C = 3 + 3 + 2 = 8 miles.
4. The shorter open route is 8 miles.

6 miles: This adds only Depot–D (3) and D–E (3) and stops at E without the last 2 miles to C.

8 miles: Correct. Depot–D–E–C is 3 + 3 + 2 = 8 miles, shorter than Depot–A–B–C (4 + 3 + 4 = 11 miles).

9 miles: This uses the B–D road (3 + 2 + 4 = 9), but the legend shows that road is closed.

11 miles: This is the open route along the top, Depot–A–B–C (4 + 3 + 4), which is longer.

Check the legend for closed or restricted roads before comparing routes, then add the segment distances for each route. Why this is a Level 4 item: comparing totals for routes on a map with a legend and several pieces of information.

Answer: C

1. Find the numbered marks on each side of the fuel level: 300 and 400.
2. Count the divisions between them: 5, so each mark = 100 ÷ 5 = 20 gallons.
3. The level is 3 marks above 300: 300 + 60 = 360 gallons.

315 gallons: Read each small mark as 5 gallons. The 5 divisions between numbered marks 100 apart make each mark 20 gallons.

330 gallons: Read each small mark as 10 gallons. There are 5 divisions between 300 and 400, so each mark is 20 gallons.

360 gallons: Correct. The fuel level is at the third small mark above 300. Each mark is 20 gallons (100 ÷ 5 divisions), so 300 + 3 × 20 = 360 gallons.

400 gallons: Read the nearest numbered mark instead of the level; the fuel is two marks below 400.

On any scale, work out what one small division is worth (the difference between numbered marks divided by the number of divisions) before counting marks. Why this is a Level 3 item: one simple graphic and one value to locate.
