Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

A person demonstrating competency in this unit must satisfy the requirements of the elements, performance criteria, foundation skills and range of conditions of this unit. The person must also accurately perform the following computations for two different surveying tasks:

calculate areas from bearings and distances or coordinates

calculate angles, distances, perimeter and area for simple and complex figures

set out data for simple horizontal curves

calculate surveying data required to set out the position of curves and structures

traverse calculations in east, north, misclose and adjustment calculations, and calculations based on adjusted coordinates

traverse types, include opening and closing on same point and different points of known coordinates.

While performing the above surveying computations, the person must:

communicate clearly with others to clarify work tasks and computational results

comply with organisational requirements and industry-accepted standards for:

systematically and legibly laying out computations

completing records and documentation

examine the computational results and verify the accuracy of results.

A person demonstrating competency in this unit must demonstrate knowledge of:

common computational terms used in surveying

industry-accepted methods for performing surveying computations in a plane coordinate system

methods for checking accuracy of computations to identify errors and solve problems

methods for computing basic traverse data

organisational procedures for completing surveying records and documentation.

Range Statement

This section specifies work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Bold italicised wording, if used in the performance criteria, is detailed below.

Appropriate persons must include at least one of the following:

client
