Evidence Guide


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 following is essential:

  • Assessment must confirm the ability to install and improve system performance with minimum disruption to clients.

To demonstrate competency in this unit the person will require access to:

  • Personal computer/workstation

Operating System software and technical documentation

Context of and specific resources for assessment 

The breadth, depth and complexity of knowledge and skills in this competency would cover selecting, adapting and transferring skills and knowledge to new environments and providing technical advice and some leadership in resolution of specified problems. This would be applied across a range of roles in a variety of contexts with some complexity in the extent and choice of options available.

Assessment must ensure:

  • Performance of a defined range of skilled operations, usually within a range of broader related activities involving known routines, methods and procedures, where some discretion and judgement is required in the section of equipment, services or contingency measures and within known time constraints would be characteristic.

  • Applications may involve some responsibility for others. Participation in teams including group or team coordination may be involved.

Method of assessment 

The purpose of this unit is to define the standard of performance to be achieved in the workplace. In undertaking training and assessment activities related to this unit, consideration should be given to the implementation of appropriate diversity and accessibility practices in order to accommodate people who may have special needs. Additional guidance on these and related matters is provided in ICA05 Section 1.

  • Competency in this unit should be assessed using summative assessment to ensure consistency of performance in a range of contexts. This unit can be assessed either in the workplace or in a simulated environment. However, simulated activities must closely reflect the workplace to enable full demonstration of competency.

  • Assessment will usually include observation of real or simulated work processes and procedures and/or performance in a project context as well as questioning on underpinning knowledge and skills. The questioning of team members, supervisors, subordinates, peers and clients where appropriate may provide valuable input to the assessment process. The interdependence of units for assessment purposes may vary with the particular project or scenario.

Guidance information for assessment 

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

  • ICAS3024B Provide basic system administration
  • ICAT3025B Run standard diagnostic tests

An individual demonstrating this competency would be able to:

  • Demonstrate some relevant theoretical knowledge
  • Apply a range of well-developed skills
  • Apply known solutions to a variety of predictable problems
  • Perform processes that require a range of well-developed skills where some discretion and judgement is required
  • Interpret available information, using discretion and judgement
  • Take responsibility for own outputs in work and learning
  • Take limited responsibility for the output of others
  • Maintain knowledge of industry products and services
