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 CPPSIS5053A Perform advanced surveying computations, and CPPSIS5054A Perform geodetic surveying computations.
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:
applying checks wherever necessary
applying formulas appropriately and obtaining correct results
assessing and recording geodetic computations from varied sources
defining terms used in geodetic calculations
demonstrating a sound understanding of the requirement for accuracy in calculations
performing calculations in a logical progression to solve geodetic surveying problems
understanding mathematical concepts, astronomical concepts and the determination of shadowing effects.
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 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.
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.
