Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment	A person who demonstrates competency in this unit must be able to interpret and apply drawing specifications in the production of electrical diagrams and drawings to Australian Standard AS Graphical symbols for electrotechnical documentation General information and general index or equivalent
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria including required knowledge and be capable of applying the competency in new and different situations and contexts Specifically the candidate must be able to work within typical siteteamwork structures and methods apply worksite communication procedures comply with organisational policies and procedures including quality requirements participate in work meetings comply with quality requirements use industry terminology apply appropriate safety procedures obtain required information for work and produce detailed electricalelectronic schematic drawings in accordance with AS Graphical symbols for electrotechnical documentation General information and general index or similar
Context of and specific resources for assessment	This unit may be assessed on the job off the job or a combination of both on and off the job Where assessment occurs off the job that is the candidate is not in productive work then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team Where applicable reasonable adjustment must be made to work environments and training situations to accommodate ethnicity age gender demographics and disability Access must be provided to appropriate learning andor assessment support when required Where applicable physical resources should include equipment modified for people with disabilities This unit could be assessed in conjunction with any other units addressing the safety quality communication materials handling recording and reporting associated with drafting or other units requiring the exercise of the skills and knowledge covered by this unit
Method of assessment	Assessors should gather a range of evidence that is valid sufficient current and authentic Evidence can be gathered through a variety of ways including direct observation supervisors reports project work samples and questioning Questioning techniques should not require language literacy and numeracy skills beyond those required in this unit of competency The candidate must have access to all tools equipment materials and documentation required The candidate must be permitted to refer to any relevant workplace procedures product and manufacturing specifications codes standards manuals and reference materials
