Resource implications 

Glass toughening equipment, workplace operating procedures, unprocessed materials, personal protective equipment and an appropriate work area.

Method of assessment 

Assessment methods must confirm consistency of performance over time and in a range of workplace relevant contexts.

Assessment should be by direct observation of tasks and questioning on underpinning knowledge.

Assessment may be in conjunction with assessment of other relevant units of competency.

Context of assessment 

Assessment may occur on the job or in a workplace simulated facility with relevant glass toughening equipment, materials, work instructions and deadlines.
