Supervision and Workplace Instruction
What this domain tests
This domain tests your ability to lead a small team, instruct apprentices and check work without taking over. Level 3 mechanics are often expected to act as team leader for a job, not just complete the task themselves.
Core rules
- Match the task to the person's competence. An apprentice should not be left alone on brakes, SRS, high-voltage or air-conditioning work without supervision.
- Use a four-step job instruction: prepare the learner, present the job step by step, let them try while you observe, then follow up and correct.
- Give a toolbox talk before the shift on the specific hazards of the day: vehicle on stands, battery charging, grinding, hot oil.
- Delegate the task and the authority to stop for safety; do not delegate accountability for the final quality check.
- Check work at defined hold points, such as after torqueing suspension bolts or before closing a transmission. Sign the job card only after the check.
- Give feedback on behaviour and result, not personality; correct unsafe acts immediately and record training.
Worked example
A supervisor assigns a first-year apprentice to remove a front wheel. The supervisor demonstrates the jacking point, the wheel-nut loosening sequence and the stand position, then asks the apprentice to repeat the steps. The apprentice places the stand under the sill instead of the subframe. The supervisor stops the job, explains the crush risk, shows the correct point and has the apprentice repeat it correctly before continuing. The reasoning is that the hold point caught a safety error before the vehicle was raised, and the correction was recorded in the training log.
Traps
Assuming that a quiet apprentice has understood is a common error. Do not sign off work you have not checked. Do not use a “watch me once” demonstration for a high-risk task. Failing to correct an unsafe act because it is faster to finish the job undermines the whole team. Keep training records factual.
