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

produce and evaluate design requirements for an IPTV network

design an IPTV network for VoD delivery

design and configure an MPLS IPTV network to meet business requirements

manage the delivery of IPTV services

Context of and specific resources for assessment

Assessment must ensure

protocols configuration documents management tools and standards

network and demographic trends and customer demand data

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

review of design requirements and network designs completed by the candidate

oral and written questioning of the candidate on required knowledge

direct observation of the candidate designing and configuring and MPLS IPTV network and managing IPTV services

Guidance information for assessment

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

ICTTENA Design and configure an IPMPLS network with virtual private network tunnelling

ICTTEN6172A Design and configure an IP-MPLS network with virtual private network tunnelling.

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

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. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
