Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.	Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Evidence Guide

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 connect network hardware devices to an internet gateway and configure and test them. To demonstrate competency in this unit the learner will require access to: Network with internet access Personal computer
Context of and specific resources for assessment	An internet gateway is the hardware or software set-up that translates between two dissimilar protocols and which provides a system for converting messages between TCP/IP and other protocols. Using internet gateways, various networks around the world can effectively become one large network. By reviewing a variety of internet gateways and talking with ISPs, a better understanding of gateway products and their applications will be achieved. Any internet gateway needs to be configured according to the needs of the client and consideration should be given to redundancy with reference to fault tolerance and back-up links. The breadth, depth and complexity covering planning and initiation of alternative approaches to skills or knowledge applications across a broad range of technical and/or management requirements, evaluation and coordination would be characteristic. The demonstration of competency may also require self-directed application of knowledge and skills, with substantial depth in some areas where judgement is required in planning and selecting appropriate equipment, services and techniques for self and others. Assessment must ensure: Applications involve participation in development of strategic initiatives as well as personal responsibility and autonomy in performing complex technical operations or organising others. It may include participation in teams including teams concerned with planning and evaluation functions. Group or team coordination may also 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. An individual demonstrating this competency would be able to: Demonstrate understanding of a broad knowledge base incorporating theoretical concepts, with substantial depth in some areas Analyse and plan approaches to technical problems or management requirements Transfer and apply theoretical concepts and/or technical or creative skills to a range of situations Evaluate information, using it to forecast for planning or research purposes Take responsibility for own outputs in relation to broad quantity and quality parameters Take some responsibility for the achievement of group outcomes Maintain knowledge of industry products and services
