Identify potential health impacts of equine oral conditions

Assessment tool

Version 1.0
Issue Date: March 2023

The Unit is applicable to the equine industry where it may be necessary to provide dental care to ensure the health and efficient physiological function of horses.In addition to legal and ethical responsibilities, all Units of Competency in the ACM10 Animal Care and Management Training Package have the requirement for animals to be handled gently and calmly. The individual is required to exhibit appropriate care for animals so that stress and discomfort are minimised.

This Unit of Competency covers the process of evaluating the anatomy and physiology of the equine head, with specific reference to how the teeth and dental related structures, can affect the health of horses.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)


There are no pre-requisite Units for this competency standard.

Employability Skills

This Unit contains employability skills.

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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:

describe the process of mastication and nutrient absorption and the impact of poor occlusion or masticatory action on the health of the horse

condition score the horse

evaluate a range of ailments, diseases and injuries that could occur as a result of unskilled or inappropriate dental care

identify evidence of unskilled or inappropriate dental care.

The skills and knowledge required to identify potential health impacts of equine oral conditions 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 dental workplace or in a situation that reproduces normal work conditions.

There must be access to a range of horses and 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 candidate’s required knowledge

observed, documented and first-hand testimonial evidence of candidate’s application of practical tasks

simulation exercises that reproduce normal work conditions

case studies

third-party 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 (e.g. literacy and numeracy demands) and the needs of particular target groups (e.g. people with disabilities, Aboriginal and Torres Strait Islander people, women, people with a language background other than English, youth and people from low socio-economic backgrounds).

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

employ safe and environmentally responsible organisational systems and procedures when working with and handling horses

follow sequenced written instructions, record accurately and legibly information collected and select and apply procedures to a range of defined tasks

identify evidence of conditions, practices, devices or structures which have been contributing to pain or distress to the horse, while at liberty (grazing/feeding) or under restraint (handling, riding, driving)

identify potential causes of poor condition and behaviour issues in the horse related to dental care or dental condition

interpret behavioural signals of the horse

maintain the highest standards of hygiene and infection control at all times to reduce the risk of infection and cross-infection considering zoonotic and exotic disease possibilities (biosecurity)

prepare and maintain equine records using appropriate terminology

read, understand and follow required policies and procedures, including OHS, infection control and waste management

use safe manual handling techniques and equipment

use safe, hygienic and environmentally friendly waste handling and disposal procedures.

Required knowledge includes:

Knowledge of:

anatomy and physiology of the equine head and oral structures including features and functions of the equine mouth and teeth including normal and abnormal functions

anatomical directional terminology

appropriate industry and state/territory equine dental codes of conduct and standards of practice

causes and consequences of horse ailments, infections and injuries relevant to dental care

contagious disease symptoms, prophylaxis and biosecurity protocols

established dental terminology related to equine dental care

features of correctly formed, healthy and well-maintained equine dental and oral structures

indicators of horse distress, illness and disease

influence of different diets and husbandries on mastication and oral health

normal and abnormal features of equine dental and oral structures including physiology and effect of diet

nutritional requirements and digestive processes of the horse

principles of animal welfare

relevant legislation, regulations and codes of practice, including OHS, animal welfare and ethics, veterinary practice, restricted dental practices and waste disposal

relevant state or territory legislation covering the supply, possession and use of restricted and controlled substances

safe work practices

techniques and instruments used to provide equine dental care

workplace hygiene standards (biosecurity) including: disinfectants, cleaning agents and techniques, cleaning and appropriate disinfection or sterilisation of equipment, materials and personal protective equipment (PPE).
