SDUSD Nursing & Wellness Lice Toolkit

San Diego Unified School District's head lice policy is in alignment with the guidance of the American Academy of Pediatrics, the National Association of School Nurses and the California School Nurse Organization. 

The problem of head lice (pediculosis) is ongoing and can be difficult to control at home and at school. Head lice and nits (eggs) are not a threat to health but are a frustrating nuisance. Treating students with a positive diagnosis of head lice promptly ensures minimal disruption of their education. 

When a student is identified as having head lice, the student will be sent home at the end of the school day for treatment. It is the responsibility of the parent/guardian to treat and control head lice infestation. The key to success in controlling head lice is in the removal of all nits after the use of the pediculicide. 

After home treatment, it is mandatory for the student to return to school the next day for inspection at the health office. The student may return to class provided the head lice have been treated and there are no live lice in the hair, even if nits (eggs) are still present. Parents/guardians should continue removing nits until the problem is resolved. 

There is no evidence that mass screenings (school-wide or whole classrooms) help to control head lice infestation or re-infestation. Parents/guardians are encouraged to incorporate inspecting their child’s hair as part of their regular hygiene routine (BP 5141 .33). 

The American Academy of Pediatrics does not recommend schools sending "alert letters" as these can violate privacy laws and cause unnecessary public alarm. School site administrators can choose to add educational material to their weekly communication with their school community. The CDPH Handout on Lice is a great option to share with school communities.
