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.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors should ensure that candidates can:

use observations skills to locate samples/evidence

interpret and apply evidence/sample collection methods accurately

safely locate, record, collect, transport and store samples/evidence

keep accurate records

communicate any problems to a supervisor or industry professional

maintain security, integrity and traceability of samples/evidence, sub-samples and documentation.

Context of and specific resources for assessment

This unit of competency is to be assessed in the workplace or simulated workplace environment.

Resources may include:

enterprise procedures and standard methods

sample containers

containers for transporting samples.

Method of assessment

The following assessment methods are suggested:

review of job sheets or journal of completed activities

review of workplace documentation completed by the candidate

observation of candidate collecting a range of samples/evidence

feedback from peers, supervisors and industry professionals

oral or written questioning of required knowledge.

In all cases, practical assessment should be supported by questions to assess required knowledge and those aspects of competency which are difficult to assess directly.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

Access must be provided to appropriate learning and/or assessment support when required.

The language, literacy and numeracy demands of assessment should not be greater than those required to undertake the unit of competency in a work place environment.

Required Skills and Knowledge

Required skills include:

completing chain of custody forms according to judicial and enterprise requirements

communicating with supervisors and industry professionals using current and appropriate terminology

maintaining integrity and security of all items of evidence/samples

storing and transporting samples according to judicial and enterprise protocols

techniques for documenting, collecting, packaging, preserving and transporting forensic evidence/samples

Required knowledge includes:

legislative, regulatory, policy, procedural and quality system requirements for the location, collection, preservation, security, continuity and disposal of samples and evidence (exhibits)

terminology and principles of locating, recording, collecting, storing and transporting samples/evidence

potential limitations of own specialist knowledge and when to seek advice from other services

services available to assist in the documenting, collection, preservation and continuity of forensic evidence/samples

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.
