Assessment guidance
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.

Resources

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

Network technical requirements
Network infrastructure, including wireless hardware and software

Role context
The breadth, depth and complexity of knowledge and skills in this competency would cover a broad range of varied activities or application in a wider variety of contexts most of which are complex and non-routine. Leadership and guidance would be involved when organising activities of self and others as well as contributing to technical solutions of a non-routine or contingency nature.
Performance of a broad range of skilled applications including the requirement to evaluate and analyse current practices, develop new criteria and procedures for performing current practices and provision of some leadership and guidance to others in the application and planning of the skills would be characteristic.
Applications may involve responsibility for, and limited organisation of, others.

An individual demonstrating this competency would be able to:

Demonstrate understanding of a broad knowledge base incorporating some theoretical concepts
Apply solutions to a defined range of unpredictable problems
Identify and apply skill and knowledge areas to a wide variety of contexts, with depth in some areas
Identify, analyse and evaluate information from a variety of sources
Take responsibility for own outputs in relation to specified quality standards
Take limited responsibility for the quantity and quality of the output of others
Maintain knowledge of industry products and services
