Marin County School Head Lice Policy

Updated on July 19, 2020

Schools in Marin County do not adhere to a strict “no nit” policy with regard to children with head lice attending class. If a child is found to have an active case with live adult lice, he or she will be sent home at the end of the day with suggestions for treatment. The student will be allowed to return to the classroom the following day as long as treatment has commenced and no live bugs are detected.


If a student is found with active, adult head lice, he/she shall be allowed to stay in school until the end of the school day. The parent/guardian of any such student shall be given information about the treatment of head lice and encouraged to begin treatment of the student immediately and to check all members of the family. The parent/guardian also shall be informed that the student shall be checked upon return to school the next day and allowed to remain in school if no active head lice are detected.

Upon the student's return to school, the school nurse or designee shall check the student for active head lice. If it is determined that the student remains infected with head lice, the school nurse or designee shall contact the student's parent/guardian to discuss treatment. As needed, he/she may provide additional resources and/or referral to the local health department, health care providers, or other agencies.

If a student is found consistently infested with head lice, he/she may be referred to a multidisciplinary team, which may consist of the school nurse, representatives from the local health department and social services, and other appropriate individuals, to determine the best approach for identifying and resolving problems contributing to the student's head lice infestations.

When it is determined that one or more students in a class or school are infested with head lice, the principal or designee may, at his/her discretion, notify parents/guardians of students in that class or school and provide them with information about the detection and treatment of head lice.

Staff shall maintain the privacy of students identified as having head lice.
