Head Lice in Schools

The School Health Bureau uses the most up-to-date, evidence-based guidance when making recommendations. After reviewing current guidance from the Centers for Disease Control and Prevention, the American Academy of Pediatrics, and the National Association of School Nurses, we updated our head lice policy to reflect best practices for schools.

What health experts agree on

  • Head lice are common and do not cause serious health problems
  • Children should not miss school because of head lice
  • Head lice rarely spread at school
  • Students should not be singled out because of head lice
  • Head lice are not related to cleanliness or hygiene
  • Schoolwide lice screenings do not reduce cases and are not cost-effective

School Health Program practices

Based on this guidance:

  • Children with live lice or nits may stay in school
  • If a student is suspected of having head lice, they may be sent to the clinic for an exam
    • The student will return to class with a note for the teacher explaining the results
    • Even if lice or nits are found, the student should stay in class for the rest of the day and should not be treated differently
    • Clinic staff will share treatment and prevention information with the student's guardian
    • Guardians are responsible for treating the child after school
  • The clinic will not screen entire classrooms or groups for lice
  • If another student shows symptoms within four weeks and is confirmed to have live lice, School Health will send a letter to families in that class recommending they check and treat their child if needed 
    • No additional students will be examined in the clinic
  • Students who do not respond to standard treatment should be referred to their primary care provider

Head lice facts

  • Head lice crawl; they do not hop or fly
  • Lice spread through direct head-to-head contact
  • Do not share personal items such as hats, scarves, combs, brushes, or towels which can spread lice
  • Cleanliness at home or school does not prevent head lice
