About the exam
Plumber Level 1 is the first level of technical training in the Plumber apprenticeship in British Columbia. At the end of the level, apprentices write a SkilledTradesBC Standardized Level Exam (SLE). This exam applies to Level 1 technical training that starts on or after October 5, 2026, and follows the revised program outline launched on August 18, 2025.
The Level 1 exam has 100 questions. SkilledTradesBC publishes the split: Perform Safety-Related Functions (10), Use Tools and Equipment (24), Perform Routine Trade Activities (39: math and science 24, codes, regulations and standards 3, interpreting drawings 12), Prepare Piping and Components (22), Use Communication Techniques (1) and Apply Electrical Concepts (4). The exam is 20% of the final mark, and a blended final mark of 70% or more is needed to pass the level. No code book is required; an acronym list and a formula list are in the exam reference booklet. Time limit and calculator rules are not stated in the sources.
ExamHub's free practice quiz has 161 original questions. Test mode draws 100 questions using the exam's block weights, with a 70% practice target and a 120-minute practice timer.

Five sample questions from the question bank, with the answer and explanation.
Why: Estimated exposure is the noise level minus the NRR: 105 - 25 = 80 dB. The target is a device that reduces exposure to 85 dB or less.
Why: Free acetylene reaches a critical point at 28 psi and breaks down explosively, so to allow for temperature changes it should not be stored or used at pressures over 15 psi (103 kPa).
Why: Convert 900 mm to 0.9 m first: V = 2.5 x 1.8 x 0.9 = 4.05 m³. Since 1 m³ = 1,000 L, capacity = 4,050 L.
Why: 62 x 100 = 6,200 mm (6.2 m). Using 50 gives 3,100; a decimal slip gives 620 or 62,000.
Why: Globe valves are preferred for throttling; seat opening is proportional to handwheel turns.
