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

capture customer functional needs for cabling system

apply industry standards regulations and codes when designing the wiring system for customer premises

develop a detailed design in compliance with industry practices including signal losses andor expected measurements that need to be achieved at wallplates

document the design including a bill of materials schedule of work and associated costs

Context of and specific resources for assessment

Assessment must ensure

candidate is provided with a contemporary dwelling design which covers all functional requirements of a modern home

candidate has access to all current standards codes and regulations

Method of assessment

A range of assessment methods should be used to assess practical skills and knowledge The following examples are appropriate for this unit

direct observation of the candidate communicating with the customer

review of the planning sheets used by the candidate in developing the design

oral and written questioning to assess candidate skills and knowledge

Guidance information for assessment

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

ICTTENB Design install and configure a customer smart technology network

ICTTEN4229B Design, install and configure a customer smart technology network.

Aboriginal people and other people from a nonEnglish 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
