Evidence Required
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 evidence required to demonstrate competence in this unit | Assessment must confirm ability to: assist with the control and treatment of disease recognise and report actual and potential disease problems. Assessment must confirm knowledge of: behavioural traits of problem species techniques for disease control. |
Context of and specific resources for assessment | Assessment is to be conducted at the workplace or in a simulated work environment and should cover the range of diseases typically found in the region. Resources may include: culture or holding structures with/in water containing stock and threatened by actual and/or potential disease data sheet for recording observations and actions work procedures for treatment and control of diseases treatments and equipment for treating/preventing diseases. |
Method of assessment | The following assessment methods are suggested: demonstration practical exercises project work written or oral short-answer testing. |
Guidance information for assessment | This unit may be assessed holistically with other units within a qualification. |
