Modification History



Release 1

This Unit first released with ICA11 Information and Communications Technology Training Package version 1.0

Unit Descriptor

This unit describes the performance outcomes, skills and knowledge required to modify and connect system hardware components according to client and user requirements.

Application of the Unit

This unit applies to support technicians who modify and connect system components. Ensuring the integrity of the system after the operation is critical in the context of minimising client disruption and need for continuing desktop operation.

Licensing/Regulatory Information

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement but users should confirm requirements with the relevant federal, state or territory authority.


Not applicable.

Employability Skills Information

This unit contains employability skills.

Elements and Performance Criteria Pre-Content


Performance Criteria 

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.

Required Skills and Knowledge

This section describes the skills and knowledge required for this unit.

Required skills 

  • communication skills to:
  • consult with peers and supervisors, and internal and external clients
  • interpret technical computer installation manuals
  • interpret user manuals and help functions
  • literacy skills to:
  • organise resources for one-to-one instruction
  • plan, prioritise and organise work
  • write technical reports and maintain records
  • planning and organisational skills to address technical issues
  • problem-solving skills to anticipate and respond to a range of driver-related errors that may arise
  • technical skills to:
  • comprehend how the operating system will communicate with the installed component
  • install components
  • test components using available technology
  • test system performance.

Required knowledge 

  • areas of the operating system relevant to configuration and testing
  • current industry-accepted hardware and software products
  • environmental considerations in e-waste disposal
  • organisational guidelines and organisational requirements with regard to safety, recycling and component installation
  • system's diagnostic software and current functionality
  • vendor specifications and requirements for component installation.

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 ability to:

  • identify and categorise the different types of internal hardware components
  • modify system's hardware to meet client requirements
  • plan the modification and connect internal hardware components according to vendor and technical specifications
  • install components across a variety of situations and account for unexpected contingencies.

Context of and specific resources for assessment 

Assessment must ensure access to:

  • personal computer and internal hardware components for installation
  • current industry standard performance testing software
  • documents detailing organisational guidelines and requirements
  • technical manuals and tools
  • appropriate learning and assessment support when required
  • modified equipment for people with special needs.

Note: The careful planning and promotion of hardware upgrades and changes are critical to the effective support of business functions. Hardware modifications need to be risk managed similar to other business processes. The effective management and execution of the component maintenance and replacement process may significantly determine the amount of downtime a company encounters.

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:

  • verbal or written questioning to assess candidate’s knowledge of system diagnostic software and system functionality
  • direct observation of candidate connecting internal hardware components
  • evaluation of client requirements and candidate’s final recommendations
  • review of candidate’s written notes.

Note: Evidence for assessment from industry or vendor-certified training may be presented for the whole or part of this unit depending on the range of variables and performance criteria.

Guidance information for assessment 

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, where appropriate.

Assessment processes and techniques must be culturally appropriate, and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed.

Indigenous people and other people from a non-English speaking background may need additional support.

In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge.
