This unit applies to operators who troubleshoot and rectify wet end systems in the pulp and paper industry. This work typically involves complex integrated equipment and continuous operations

This unit generally applies to those who:

identify and analyse the causes of systems and quality faults

rectify systems, equipment faults

record and report process performance and product quality data

to meet safety, quality and productivity requirements

It does not include monitoring and controlling, starting up or shutting down wet end operations

This unit describes the outcomes required to troubleshoot and rectify wet end systems in the pulp and paper industry

General legislation, regulatory, licensing and certification requirements applicable to this unit are detailed in the range statement

Specific high risk (and non-high risk) load shifting licensing requirements for this unit may be applicable and are to be met separately and prior to the achievement of this unit

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 should be relevant to the work. It should satisfy the requirements of the elements and performance criteria and include consideration of:

the required knowledge and skills tailored to the needs of the specific workplace

applicable OHS regulations, environmental and safe working requirements/practices, SOP and housekeeping requirements

applicable aspects of the range statement

practical workplace demonstration of skills in troubleshooting and rectifying wet end systems

Context of and specific resources for assessment

A workplace assessment must be used to assess:

the application of required knowledge on the job

the application of skills on the job, over time and under a range of typical conditions that may be experienced in wet end operations

Access to the full range of equipment involved in integrated continuous manufacturing wet end operations in a pulp or paper mill is required

Method of assessment

A combination of assessment methods should be used. The following examples are appropriate for this unit:

observation of applied skills and knowledge on the job

workplace demonstrations via a mock-up or simulation that replicate part/s of the job

answers to written or verbal questions about specific skills and knowledge

third-party reports from relevant and skilled personnel

written evidence e.g. log sheet entries, checklist entries, test results

Assessment processes and techniques must be culturally appropriate and in keeping with the language and literacy capacity of the learner and the work being performed. This includes conducting an assessment in a manner that allows thoughts to be conveyed verbally so that the learner can both understand and be understood by the assessor (e.g. use plain English and terminology used on the job)

A holistic assessment with other units relevant to the pulp and paper industry, mill and job role is recommended

Additional information on approaches to assessment for the pulp and paper industry is provided in the Assessment Guidelines for this Training Package

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
