Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria Required Skills and Knowledge the Range Statement and the Assessment Guidelines for this Training Package The Evidence Guide forms an integral part of this unit It must be used in conjunction with all components parts of this unit and performed in accordance with the Assessment Guidelines of this Training Package

Overview of Assessment

Longitudinal competency development approaches to assessment such as Profiling require data to be reliably gathered in a form that can be consistently interpreted over time This approach is best utilised in Apprenticeship programs and reduces assessment intervention It is the industrypreferred model for apprenticeships However where summative or final assessment is used it must include the application of the competency in the normal work environment or at a minimum the application of the competency in a realistically simulated work environment In some circumstances assessment in part or full can occur outside the workplace However it must be in accordance with industry and regulatory policy Methods chosen for a particular assessment will be influenced by various factors These include the extent of the assessment the most effective locations for the assessment activities to take place access to physical resources additional safety measures that may be required and the critical nature of the competencies being assessed The critical safety issues inherent in working with electricity electrical equipment gas or any other hazardous substancematerial present a challenge for those determining competence Sources of evidence need to be rich in nature to minimise error in judgment Activities associated with normal everyday work influence decisions about howhow much the data gathered will contribute to its richness Some skills are more critical to safety and operational requirements while the same skills may be more or less frequently practised These points are raised for the assessors to consider when choosing an assessment method and developing assessment instruments Sample assessment instruments are included for Assessors in the Assessment Guidelines of this Training Package
