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 | Evidence of the ability to: provide methodology for system maintenance produce cost benefit analysis and training for database optimisation and administration conduct system measurements develop support processes for system users manage user accounts and security procedures investigate potential system administration problems and make recommendations. |
Context of and specific resources for assessment | Assessment must ensure: a network for maintenance and analysis of special investigations equipment and systems manuals, specifications and enterprise policy. |
Method of assessment | The following assessment method is appropriate for this unit: direct observation of the candidate undertaking system measurements and investigations direct observation of the candidate providing application support, and creating and deleting user accounts review of reports and recommendations completed by the candidate for special investigations oral or written questioning to assess knowledge required to prepare methodology for system maintenance. |
Guidance information for assessment | Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example: ICTNPL6046A Undertake network performance analysis ICTTEN6043A Undertake network traffic management ICTTEN6044A Coordinate fault rectification and restoration of service following network outages ICTTEN6045A Implement planned network changes with minimal impact to the customer. Aboriginal people and other people from a non-English speaking background may have second language issues. Access must be provided to appropriate learning and assessment support when required. Assessment processes and techniques must be culturally appropriate, and appropriate to the oral communication skill level, and language and literacy capacity of the candidate and the work being performed. In all cases where practical assessment is used it will be combined with targeted questioning to assess required knowledge. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. Where applicable, physical resources should include equipment modified for people with special needs. |
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.
