This version first released with CPP07 Property Services Training Package Version 12.

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the required performance needed to demonstrate achievement of the element. Where bold italicised  text is used, further information is detailed in the required skills and knowledge and/or the range statement. Assessment of performance is to be consistent with the evidence guide.

Develop procedures for manipulating and analysing data.

1.1

Desired data  format is specified, based on job and client  requirements.

1.2

Parameters  are specified for manipulating data sets .

1.3

New procedures for manipulating and analysing data are documented clearly, explaining the procedure and rationale for development.

2

Establish models required to provide outcome.

2.1

Applicability of existing tools, models, theories, applications and solutions is reviewed.

2.2

Feasible parameters, equations and assumptions are specified.

2.3

Models required to provide specified outcomes are established.

3

Analyse data.

3.1

Processes to be undertaken to analyse and manipulate data are specified.

3.2

Source data limitations  and other restricting factors are taken into account when selecting techniques for analysis to ensure integrity of data  used.

3.3

Data is isolated and retrieved from its source, interrogated  to ensure reliability and prepared for presentation media to ensure that required outcome  is achieved.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, the range statement and the Assessment Guidelines for this Training Package.

Overview of assessment 

This unit of competency could be assessed on its own or in combination with other units relevant to the job function, for example CPPSIS5063A Produce GIS data.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

A person who demonstrates competency in this unit must be able to provide evidence of:

• producing geographic information data systems that meet the integrity of data standards and client needs
• interrogating data to ensure reliability
• knowledge of data systems and data capture and manipulation techniques.

Specific resources for assessment 

Resource implications for assessment include access to:

• assessment instruments, including personal planner and assessment record book
• assignment instructions, work plans and schedules, policy documents and duty statements
• registered training provider of assessment services
• relevant guidelines, regulations and codes of practice
• suitable venue and equipment.

Access must be provided to appropriate learning and assessment support when required.

Where applicable, physical resources should include equipment modified for people with disabilities.

Context of assessment 

Holistic: based on the performance criteria, evidence guide, range statement, and required skills and knowledge.

Method of assessment 

Demonstrated over a period of time and observed by the assessor (or assessment team working together to conduct the assessment).

Demonstrated competency in a range of situations, which may include customer/workplace interruptions and involvement in related activities normally experienced in the workplace.

Obtained by observing activities in the field and reviewing induction information. If this is not practicable, observation in realistic simulated environments may be substituted.

Guidance information for assessment 

Assessment requires that the clients’ objectives and industry expectations are met. If the clients’ objectives are narrowly defined or not representative of industry needs, it may be necessary to refer to portfolio case studies of a variety of SIS requirements to assess competency.

Oral questioning or written assessment and hypothetical situations (scenarios) may be used to assess underpinning knowledge (in assessment situations where the candidate is offered a preference between oral questioning or written assessment, questions are to be identical).

Supplementary evidence may be obtained from relevant authenticated correspondence from existing supervisors, team leaders or specialist training staff.

All practical demonstration must adhere to the safety and environmental regulations relevant to each State or Territory.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised  wording in the performance criteria is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts.
