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 power generation 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 power generation system operations

Access to the full range of equipment involved in integrated continuous manufacturing for power generation systems 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
