Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

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:

determine the most appropriate methods for backup and recovery

implement backup and restore procedures with minimum disruption to the business, following contingency plan if necessary.

Context of and specific resources for assessment

Assessment must ensure access to:

documentation standards

backup and recovery policies

sites with a representative range of current industry standard software and diagnostic tools

database package with data

technical records

organisational guidelines

vendor documentation

server and networked personal computer on which to conduct backup and restore procedures

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 performing backup and restore procedures

review of candidate’s documentation containing:

planning

backup schedule

contingency plan

verbal or written questioning to assess candidate’s knowledge of:

backup and restore techniques and procedures

risks and failure scenarios that are likely or possible.

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.

Required Skills and Knowledge

Required skills

analytical skills to:

evaluate a range of backup and restoration methods

undertake non-routine work processes

literacy skills to:

prepare documentation

read and interpret technical manuals

set benchmarks and identified scope

planning and organisational skills to:

develop plans with prioritised tasks

minimise disruption to client

problem-solving skills in non-routine work processes

research skills for identifying, analysing and evaluating broad features of a particular business domain and best practice in backup and recovery strategies

technical skills to:

run backup process

set backup schedule

test restore process.

Required knowledge

broad knowledge of:

diagnostic tools

structured query language (SQL)

principles of databases

tuning methodologies

detailed knowledge of:

backup and recovery methods

database administration

database security

open file backup procedures and restore operations.
