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

Overview of assessment

Competency must be demonstrated in the ability to perform consistently at the required standard.

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

Assessors must be satisfied that the candidate can competently and consistently apply the skills covered in this unit of competency in new and different situations and contexts. Critical aspects of assessment and evidence include:

planning and implementing the day-to-day noise management activities for a site, project or ongoing program

explaining noise monitoring plans, monitoring methods operation of monitoring instruments and noise control/reduction strategies clearly and accurately

verifying the accuracy and completeness of noise data, results and technical records

investigating unexpected or unacceptable noise results in a logical and efficient manner

reporting noise results, performance and opportunities for improvements in accordance with enterprise procedures

maintaining noise records in accordance with legislative/licensing/enterprise requirements.

Context of and specific resources for assessment

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

Assessment should emphasise a workplace context and procedures found in the candidate’s workplace.

This unit of competency may be assessed with:

MSS027011A Select, commission and maintain environmental monitoring instruments.

The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team.

Resources may include:

site/project/program history

relevant legislation, codes, standards, enterprise environmental management policies, plans, actions, procedures, checklists and equipment manuals

noise data sets, records and reports, and noise control/reduction strategies

monitoring methods and description of monitoring set-up, access to monitoring instruments

computer and relevant software or enterprise information management system.

Method of assessment

The following assessment methods are suggested:

review of noise data files, results and records verified by the candidate

feedback from managers and site personnel regarding the candidate’s ability to safely coordinate day-to-day noise monitoring activities

review of reports and recommended improvements to noise monitoring or noise control/reduction prepared by the candidate

questions to assess understanding of procedures governing the validation of data; acceptability of data/results; sources of noise data variability, interferences and uncertainty; and relevant preventative or corrective actions

analysis of case studies/reports of relevant noise management issues and incidents

observation of the candidate providing information and/or instruction to other personnel about noise monitoring and/or control and reduction strategies.

In all cases, practical assessment should be supported by questions to assess underpinning 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.

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