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!

  1. Herd details and health status are established in consultation with dairy farmer.
  2. Overall machine specifications are recorded to establish expected performance.
  3. Component condition is assessed and recorded.
  4. Occupational Health and Safety (OHS) hazards are identified and risks assessed in line with workplace OHS and industry standards, and reported to supervisor.

Instructions to Assessors

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following:

disassemble and reassemble milking machines and equipment

operate milking machine testing equipment

calculate effective reserve and vacuum pump capacity for the plant

measure air consumption and component leakage, and adjust vacuum to optimise performance

record measurements of milking machine performance

identify and make appropriate recommendations to the dairy manager.

Context of and specific resources for assessment

Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances.

Required Skills and Knowledge

Required skills

identify hazards and implement safe operating procedures

complete the necessary calculations and identify leakage and defects isolated from a machine test

competently disassemble and reassemble milking machines and equipment

competently operate milking machine testing equipment

effectively communicate with the farmer or shed manager and relevant industry professionals

access and interpret relevant industry standards

identify and make appropriate recommendations on aspects of milking equipment and shed safety identified during equipment testing procedures

demonstrate the use of tools and testing equipment, and in the disassembly and reassembly milking equipment

use literacy skills to read, interpret and follow organisational policies and procedures, follow sequenced written instructions, record accurately and legible information collected and select and apply procedures for a range of tasks

use interpersonal skills to work with and relate to people from a range of cultural, social and religious backgrounds and with a range of physical and mental abilities.

Required knowledge

the International Standards ISO 6690 - 1983 ( Mechanical Tests) and ISO5707 ( Construction and Performance) together with the Industry Standard Minimum recommendations established by the Australian Milking Machine Trade Association are the basis of testing procedures - knowledge needs to include an awareness of these documents and an ability to use and interpret their contents in a working environment

OHS hazards associated with milking machines and principles of risk control including machine guarding, protection from hot water or steam scalds, noise control, electrical safety in the dairy, and the responsibilities of people in the workplace

vacuum requirements, pulsation and the interaction between these characteristics in a milking machine

the components that make up milking equipment

how milking machines work

pulsation systems, e.g. difference between 2x2 or 4x1 systems
