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 specifies the evidence required to demonstrate achievement in the unit of competency as a whole. It must be read in conjunction with the Unit descriptor, Performance Criteria, the Range Statement and the Assessment Guidelines for the Public Sector Training Package.

Units to be assessed together

Pre-requisite units that must be achieved prior to this unit:Nil

Co-requisite units that must be assessed with this unit:Nil

Co-assessed units that may be assessed with this unit to increase the efficiency and realism of the assessment process include, but are not limited to:

PSPETHC501B Promote the values and ethos of public service

PSPGOV503B Coordinate resource allocation and usage

PSPGOV504B Undertake research and analysis

PSPGOV520A Scope statistical data collection

PSPGOV521A Collect statistical data

PSPGOV522A Process statistical data

PSPGOV523A Interrogate and analyse statistical data

PSPLEGN501B Promote compliance with legislation in the public sector

Overview of evidence requirements

In addition to integrated demonstration of the elements and their related performance criteria, look for evidence that confirms:

the knowledge requirements of this unit

the skill requirements of this unit

application of Employability Skills as they relate to this unit

interpretation of data and related statistics in a range of (3 or more) contexts (or occasions, over time)

Resources required to carry out assessment

These resources include:

legislation, policy, procedures and protocols relating to interpretation of statistics

tools/equipment for interpreting and explaining statistics

case studies and workplace scenarios to capture the range of situations likely to be encountered when undertaking statistical interpretation

Where and how to assess evidence

Valid assessment of this unit requires:

a workplace environment or one that closely resembles normal work practice and replicates the range of conditions likely to be encountered when interpreting data and related statistics, including coping with difficulties, irregularities and breakdowns in routine

interpretation of data and related statistics in a range of (3 or more) contexts (or occasions, over time).

Assessment methods should reflect workplace demands, such as literacy, and the needs of particular groups, such as:

people with disabilities

people from culturally and linguistically diverse backgrounds

Aboriginal and Torres Strait Islander people
