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 | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy all of the requirements of the performance criteria and required skills and knowledge. A person who demonstrates competency in this unit must be able to: observe safety procedures and requirements communicate effectively with others involved in or affected by the work select methods and techniques appropriate to the circumstances complete preparatory activity in a systematic manner conduct CNC machining of a range of engine components according to workplace, manufacturer and component supplier requirements produce engine components that comply with workplace requirements. |
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. Performance is demonstrated consistently over a period of time and in a suitable range of contexts. Assessment is to occur: using standard workplace practices and procedures following safety requirements applying environmental constraints. Assessment is to comply with relevant: regulatory requirements Australian standards industry codes of practice. The following resources must be made available for the assessment of this unit: appropriate worksite CNC machines appropriate for machining automotive engine components a range of engine components specifications and work instructions. |
Method of assessment | Assessment must satisfy the endorsed Assessment Guidelines of this Training Package. Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of required skills and knowledge. Assessment methods must be by direct observation of tasks and include questioning on required skills and knowledge to ensure its correct interpretation and application. Assessment must confirm that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances. Competence in this unit may be assessed in conjunction with other units which together form part of a holistic work role. Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability. Assessment processes and techniques must be culturally sensitive and appropriate to the language and literacy capacity of the candidate and the work being performed. |
