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 basic computations for two different surveying computational tasks, demonstrating the ability to:

calculate perimeter and areas of simple regular figures

calculate adjusted coordinates of points on a closed traverse

convert between:

polar and rectangular coordinates

vertical angles and gradients and vice versa

check accuracy of above computations.

During the above surveying computational tasks, the person must:

communicate clearly with others to clarify work tasks and computational results

comply with organisational requirements and industry-accepted methods for systematically and legibly laying out computations

use organisational documents to complete required records.

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

common surveying and mathematical terms used in basic surveying computations

industry-accepted methods for performing and laying out different types of basic surveying computations

organisational policies and procedures for completing surveying records and documentation.
