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!

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria under the specified conditions of assessment, and must include:

applying relevant WHS procedures

interpreting and applying work instructions and established procedures

planning and coordinating work activities

locating and interpreting technical information about machines and materials used in aircraft life support and furnishing

selecting appropriate needle and thread

identifying unsatisfactory machine performance

using relevant hand and power tools

using relevant chemicals and cleaning agents and dispose of waste products

maintaining machines and work area

applying all relevant safety practices

communicating effectively within the workplace

documenting and transferring information.

The underlying skills inherent in this unit should be transferable across a range of aircraft life support equipment maintenance activities involving the use of sewing machines/overlockers. It is essential that fabric component manufacture, repair and alteration procedures and safety precautions are fully observed, understood and complied with. Ability to interpret fabric component requirements and apply them in practice is critical.

This is to be demonstrated through demonstration of the ability to perform appropriate manufacturing, repair and alteration tasks that are within the bounds of the individual’s authority.

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:

precautions and safe working practices based on relevant WHS legislation, codes of practice, policies and procedures

advanced work piece construction principles and methods

characteristics of a wide range of materials used in aircraft life support and furnishing

operating principles of a wide range of sewing/overlocking machines

types of needles and threads and their applications

types of stitching and their applications

the range of sewing/overlocking machines, hand tools and power tools used in sewing/overlocking processes and their appropriateness for particular applications

relevant quality standards for sewn/overlocked products

power sources, such as single phase, three phase and weather protected outlets

electrical isolation procedures for sewing/overlocking machines

safety and environmental requirements of relevant industry and enterprise procedures

general housekeeping policies and procedures

recording and reporting procedures.
