Introduction

In preparation for your assessment, the trainer/assessor will advise you of the best approach in readiness for your assessment.


You are now required to show your Assessor that you are competent in the tasks that you have learned. This guide will give you all the information that you will require in order to successfully complete your assessments.

The following pages must be completed, signed and returned to the trainer/assessor.

If you have any queries regarding your assessment, you should contact the trainer/assessor for guidance.

Completing the assessment

All sections of the assessment must be completed with an ink pen.

Pre–assessment: Make sure you understand the assessment and any appeal processes. Ask the assessor to explain or clarify any information you do not understand. Both you and the assessor must sign the Pre-assessment form prior to commencing the assessment.

Performance will often need to be demonstrated over a period of time and/or in different locations. More than one assessment of a block of tasks may be necessary. Your assessor may copy any relevant part of a blank assessment tool for re-use, then date it and attach it to the original once completed.

Where appropriate, the assessor may assess your performance across different conditions e.g. wet and dry weather; day and night; different equipment attachments; different materials, etc.

Your assessor may provide suitable breaks if needed in the assessment activity between blocks of tasks.

Outcomes from your theory and other supporting evidence assessments will be reflected in the final assessment summary.

On completing the overall assessment the “Assessment Summary” sheet must be completed by both you and the assessor.

The assessor will communicate any feedback comments to you if required.

If the Not Satisfactory box is ticked, the assessor will inform you and possibly your supervisor; to discuss further training needs to be given to bring you up to a satisfactory level.

Prior to commencement, you have the right to appeal under your organisation’s Fair Treatment policy (or equivalent).

The following information outlines the assessment items you will be required to complete for this unit. For each separate assessment method there are acceptable responses recorded and parameters are set in which the assessment context is defined.

Note that some methods require collection of a number of pieces of ‘evidence’ over a period of time. Other methods, such as the theory assessment, will take a limited number of times.

Information:

Skills need to be applied in the workplace in a variety of circumstances. As such, assessors must ensure that the Candidate can competently and safely undertake the task/s being assessed in different situations and conditions, to industry standards. Sound assessment practice involves the assessor determining that Candidates/employees are able to demonstrate the required level of performance prescribed by the unit of competency consistently, over time, and in a range of workplace conditions/settings.

Assessors will evaluate the skills demonstrated by Candidates as specified in the Observation Checklist, (contained in the Assessor Guide).The Assessor will also conduct a competency conversation to determine and record your competence. In other words, these questions guide conversation with you and assist in assessment. The notes taken about this conversation are important evidence for the assessment.

The Assessor will provide feedback to you and record results appropriately.

You as the candidate should ascertain appropriate times and dates with your Supervisors/ Managers and plan for the assessment.

The Assessor should explain the elements of the observation at the pre-assessment and outline how you will be required to demonstrate competence at the time of the observation.

Assessment Method 4 Workplace Portfolio (Project)RIIUND401D Apply and monitor the ventilation management plan

You are required to research your workplace/site to build a portfolio of documentation that would support work activity you do is compliant when applying and monitoring the ventilation management plan.

Some considerations that need to be included follow:

collection, collation and interpretation of ventilation data

interpretation and application of ventilation device construction/installation specifications

conducting enquiries/investigations and preparing reports

interpreting and applying data from monitoring systems and equipment

risk management processes and techniques

ventilation training

use of monitoring equipment and ventilation/mine control devices

Please attach all relevant documentation that you would require and outline the work activity you would perform explaining how the attached documentation would support you.


Additional Section

This section provides scope for you to add supplementary assessment items. It can be used to customise additional assessment methods and/or contextualised questions.

The Context of Assessment

The RTO/Compliance Manager should take time to consult with the candidate’s site to determine the information that will complete the list below. Each of the assessment methods in this Guide should then be conducted using this list as a reference. This will help to ensure that the assessment process is consistent with the organisation’s/site’s work context.

Where assessment is being conducted in a simulated environment, the RTO should complete this page based on the documentation, policies, procedures and equipment that are used in the simulated environment. Further information about appropriate simulated assessment environments can be found in the SkillsDMC Companion Volume: Implementation Guide, available from www.skillsdmc.com.au.

The Assessor using this document should take time to familiarise themselves with the items in the list below. Where this is not possible, the Assessor should consider working with an Industry Subject Matter Expert from the organisation/site who is already familiar and experienced with the items listed.

Specific company policies that must be assessed against:

Specific company procedures (including work procedures) that must be assessed against:

Specific legislative/regulatory/statutory documentation that must be adhered to during the assessment:
