Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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:

evaluate a non-functional OS

diagnose cause of system faults

rectify the fault.

Context of and specific resources for assessment

Assessment must ensure access to:

stand-alone or networked PC

appropriate OS installation CD or recovery boot discs

drivers for connected devices

help-desk system

appropriate learning and assessment support when required

modified equipment for people with special needs.

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 candidate rectifying a boot process problem

review of candidate’s completed call documentation

verbal or written questioning to assess candidate’s knowledge of boot procedures of different OS.

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.

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

communication skills to interpret technical manuals

learning skills to maintain knowledge of current industry-accepted hardware and software products

planning and organisational skills to plan the upgrade or installation of OS, taking into account time, environment, and internal and external issues

problem-solving skills to solve client OS problems

technical skills to:

select, source and use appropriate software and tools based on analysis of technical needs

solve OS boot problems.

Required knowledge

boot processes in use

files required for operation

range of OS.

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.

Operating system may include:


Mac OS 9

Mac OS X

current Windows:

Windows 2000

Windows 7

Windows Vista

Windows XP

legacy Windows:


Windows 95

Windows 98

Windows ME

Windows NT 4.0


BSD and derivations:




GNU and Linux


Suse Linux

available open source OS.

Features may include:


file handling

internet network access

log-on procedures


user interface.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
