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:

produce a clear statement of business expectations and needs, including critical business requirements

examine the scalability and functionality of a database in light of future growth.

Context of and specific resources for assessment

Assessment must ensure access to:

DBMS

sample database

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:

review of candidate’s written report to:

explain business expectations and needs

document database functionality and scalability

evaluation of candidate’s project to assess database functionality and scalability

verbal or written questioning to determine candidate’s knowledge of business needs and scalability requirements.

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 analyse business requirements

communication skills to:

elicit information from users

liaise with technical and non-technical personnel

literacy skills to produce reports

numeracy skills to perform capacity planning

technical skills to model data processes.

Required knowledge

architecture of the network in which the database resides

Australian Computer Society Code of Ethics

common system hardware related to client, server and database architecture

data modelling

functions and features of databases

OHS principles and responsibilities in regard to self and others.

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.
