According to the 2006 preschool regulations:
No preschool children are allowed to be disciplined with corporal punishment. That means that hidings and other forms of physically violent punishment are not allowed.
Punishment may also not be intimidating, exploitative, degrading, disrespectful, or harmful (whether physically, mentally or emotionally).
Your child’s preschool or child care facility should also have a Positive Behaviour Management Policy that forms a part of its written policies and procedures.
As a parent, when you are deciding on which child care facility to use, it’s best to speak to the child care provider, and find out what this policy is. It should aim to teach your child, in a positive and developmentally appropriate way, rather than punish them when they do something regarded as wrong.
Your child’s self esteem, growth and development should always be foremost when it comes to discipline issues, and it’s wise to develop a relationship that is supportive and consistent with your child’s care givers.
