present torque converter in a condition that complies with workplace expectations.

Context of, and specific resources for assessment

Competency is to be assessed in the workplace or a simulated workplace environment that accurately reflects performance in a real workplace setting.

Assessment is to occur:

using standard workplace practices and procedures

following safety requirements

applying environmental constraints.

Assessment is to comply with relevant:

regulatory requirements
