Evidence Required

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 CPPSISA Conduct an engineering survey and CPPSISA Conduct an engineering surveying project

This unit of competency could be assessed on its own or in combination with other units relevant to the job function, for example CPPSIS5048A Conduct an engineering survey, and CPPSIS5049A Conduct an engineering surveying project.

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

assessing and recording computations from varied sources

demonstrating operational knowledge in a broad range of areas relating to traverse computations

applying mathematical principles and skills to a range of advanced surveying related problems

understanding mathematical concepts and techniques

understanding purpose of numerically solving advanced surveying problems

understanding requirement for accuracy in precision surveying calculations

defining terms used in calculations

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 that may include customerworkplace 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 surveying and spatial information services 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

Where assessment is for the purpose of recognition recognition of current competencies RCC or recognition of prior learning RPL the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time

In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge

Assessment processes will be appropriate to the language and literacy levels of the candidate and any cultural issues that may affect responses to the questions and will reflect the requirements of the competency and the work being performed
