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


Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
