The first time your preschooler wakes up with a runny nose or a low-grade fever, you may wonder: Should I keep them home? What does the school require? Every preschool has its own sick policy, but most follow guidelines from public health authorities. Understanding these policies helps you protect your child, their classmates, and the school community.

Why Preschools Have Sick Policies

Young children have developing immune systems and often spread germs before symptoms appear. Sick policies aim to reduce the spread of illness, keep children comfortable, and ensure that teachers can focus on learning. A clear policy also helps parents make consistent, confident decisions.

Common Signs That Require Staying Home

Most policies ask you to keep your child home if they have any of the following:

  • Fever of 100.4°F (38°C) or higher, taken under the arm or orally
  • Vomiting or diarrhea within the past 24 hours
  • Persistent cough, difficulty breathing, or runny nose that interferes with play
  • Rash of unknown cause, especially with fever
  • Pink eye (conjunctivitis) with discharge, until treated
  • Lice or scabies, until treatment has started

Fever Guidelines

A child should be fever-free without fever-reducing medication for 24 hours before returning. This is a common, research-backed standard. It reduces the risk that your child is still contagious or too uncomfortable to learn.

Returning to School

Even after symptoms resolve, keep in mind that some conditions (like strep throat) require at least 12 hours of antibiotics. Always check with your school for their specific return criteria. Many schools also ask that children are well enough to participate fully in outdoor play and nap times.

When Your Child Gets Sick at School

If a child develops symptoms during the day, teachers will assess and often call you to pick them up. Symptoms that typically lead to a call home include fever, vomiting, diarrhea, or an uncontrolled cough. Schools usually have a quiet isolation area where your child can wait comfortably until you arrive. Plan a backup contact list for these situations.

Partnering With Your Preschool

Strong communication builds trust. Do the following:

  • Read the school’s sick policy at enrollment and ask questions
  • Notify the school promptly if your child tests positive for a contagious illness
  • Keep your emergency contact information current
  • Understand the difference between mild symptoms (like a clear runny nose) and those that require staying home

When to Keep a Child Home Even Without a Fever

Sometimes a child feels unwell without a temperature. Trust your instincts. A child who is unusually lethargic, irritable, or unable to focus is likely better off at home. Excessive coughing that disrupts sleep or play also signals they need rest. Research shows that children recover faster and spread fewer germs when they stay home until they are truly well.

Allergies and Chronic Conditions

Some children have chronic allergies with daily runny noses or sneezing. These are not contagious. If your child has a known allergy or condition, discuss it with their teacher and pediatrician so the school can recognize typical symptoms and avoid confusion. Always provide written action plans for conditions like asthma, severe allergies, or immune disorders.

Reducing Germs at Home

To protect your family and classmates, wash hands frequently, sanitize surfaces, and teach your child to cough into their elbow. Good hand hygiene reduces the spread of common colds by up to 50 percent. Keep your child’s immunizations up to date, including the annual flu shot, to lower the risk of more serious illness.

Talk to Your Pediatrician

If you are ever unsure whether your child should go to school, call your pediatrician. They can offer guidance based on your child’s specific health needs and the current community illness level. Every child is different, and a professional opinion helps you make the safest choice.
