School exclusion for health reasons

7-minute read

Key facts

  • If your child is sick with some types of infectious disease, they may need to stay home from daycare, preschool or school for a set period — this is called school exclusion.
  • The aim of school exclusion is to reduce the spread of infectious diseases in your child's school and community.
  • Policymakers understand how important it is for your child to attend daycare, preschool or school, and only ask them to stay home when needed.
  • Each state and territory has its own policies and guidelines that determine which infections need school exclusion and for how long.

Some useful terms

Here are some useful terms:

Infectious disease — an illness caused by a germ that can be spread from one person to another.

Incubation period — the time between coming into contact with the germ and when the first signs of illness show.

Infectious period — the time period when someone with an infectious disease can spread it to another person.

Chain of infection — the steps that happen when germs spread. They are:

  • The germ comes from somewhere (the 'source').
  • The germ spreads from that place or person.
  • The germ infects another person (the 'new host').

Removing the person who is infected (the 'host') while they are infectious can help break the chain of infection and reduce the number of cases in the community.

Exclusion period — the amount of time that your child will need to stay away from school. This is usually related to the 'infectious period'.

Notifiable diseases — illnesses that your child's school or doctor must report to the government health authorities. This helps them look for outbreaks and take steps to stop the spread of infectious disease in the community.

What is school exclusion for health reasons?

Sometimes children need to stay away from daycare, preschool and school for health reasons. This is called 'school exclusion'.

Some illnesses are caused by germs that can spread from one person to another. A person who is sick with these germs may be able to spread them to others. This is known as being 'infectious'. Keeping your child away from others while they are infectious can help reduce the spread of illness to other children or people in the community.

In some cases, your child may need to be excluded because they have been in contact with another person (such as a teacher or classmate) who has an infectious disease.

Who decides if my child will be excluded and how will I know?

Each state and territory has its own guidelines for daycare, preschool and school exclusion.

These rules help stop the spread of germs at daycare centres, preschools and schools.

You can find specific information about school exclusions in your state and territory in the list below:

How long will my child be excluded from daycare or school?

How long your child needs to stay away from daycare or school may depend on:

  • the type of infection they have
  • how easily the infection can spread
  • your child's symptoms

Many schools and centres have a written policy on staying away when you're sick. Their policy should be based on government guidelines for recommended minimum exclusion periods

It can be difficult as a parent or carer to keep your child home. You may be busy with work and other commitments. But following your child's daycare or school policies is important to reduce the spread of infectious disease in your school and wider community.

How can school exclusion affect my child?

Research shows that staying home from school for a long time can affect your child's wellbeing. This is true for children of all ages, and especially for children living in rural and remote communities.

This is why each state and territory only asks children to stay home when it's needed to keep everyone healthy and safe.

What if I do not agree with the school's decision?

Sometimes your child's medical certificate may not match their school's exclusion policy.

When this happens, your child's school has the right to make the final decision if they can return to school.

It is your doctor's job to say what's making your child sick.

It is the school's job to follow their exclusion guidelines to protect other children, staff and the broader community.

If you have questions or concerns, phone your local public health unit or speak with your child's doctor or school.
