Evidence Required

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 competence in this unit must be relevant to workplace operations and satisfy all of the requirements of the performance criteria required skills and knowledge and the range statement of this Unit Assessors should ensure that candidates can

determine the structural characteristics of equine musculoskeletal system

locate and determine the function of equine muscles and supporting tissues related to locomotion power and stamina

define the changes in equine musculoskeletal system due to growth performance ailment or injury

communicate with others to describe and interpret musculoskeletal structures and features using anatomical physiological and industry terminology

The skills and knowledge required to relate musculoskeletal structure to horse movement must be transferable to a range of work environments and contexts and include the ability to deal with unplanned events

Context of and specific resources for assessment

Assessment for this Unit is to be practical in nature and will be most appropriately assessed in an equine workplace or in a situation that reproduces normal work conditions

There must be access to a range of horses and ponies anatomical models and the relevant equipment and resources to enable one to demonstrate competence

Method of assessment

To ensure consistency in performance competency should be demonstrated to industry standards on more than two occasions over a period of time in order to cover a variety of circumstances cases and responsibilities and over a number of assessment activities

The assessment strategy must include assessment of competency in a work environment Suggested strategies for this Unit are

written and oral assessment of candidates required knowledge

observed documented and firsthand testimonial evidence of candidates application of practical tasks

simulation exercises that reproduce normal work conditions

case studies

thirdparty evidence

workplace documentation

This Unit may be assessed in a holistic way with other Units of Competency relevant to the industry sector workplace and job role

Guidance information for assessment

Assessment methods should reflect workplace demands eg literacy and numeracy demands and the needs of particular target groups eg people with disabilities Aboriginal and Torres Strait Islander people women people with a language background other than English youth and people from low socioeconomic backgrounds


Range Statement

The range statement relates to the Unit of Competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Operation of the musculoskeletal system may include:

components of the musculoskeletal system:

blood supply

bones

cartilage including hoof and foot

ligaments
