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 candidates workplace

This unit of competency may be assessed with

MSSA Assess the environmental risk or impact of a project activity or process

MSS025002A Assess the environmental risk or impact of a project activity or process

MSSA Provide environmental information to customers

MSS025004A Provide environmental information to customers

MSSA Assist with odour source assessment

MSS025010A Assist with odour source assessment.

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

Resources may include

odour measuring equipment

equipment materials and reagents for field measurements

enterprise procedures standard test methods and equipment manuals

Method of assessment

The following assessment methods are suggested

review of odour data results and records prepared by the candidate

feedback from peers and supervisors that the candidate consistently follows enterprise procedures standard test methods and works safely

feedback from clients observers panellists about the candidates handling of enquiries and information

oralwritten questioning associated with odour measurements calculations a simulated case study about regulatory field assessment and community surveys

observation of the candidate conducting olfactometry testing andor instructing observerspanellists

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 worklike environment
