What is a “No Nit” Policy and Why are Schools Dropping It?

The “no nit” policy was the norm for at least the 40 years I’ve walked this earth. It was basically mandated at the school level that if you were found to have lice and/or nits (lice eggs) you would be sent home from school and not allowed to return until all traces of bugs and eggs were gone. There were varying degrees of strictness with respect to how closely schools adhered to this “no nit” policy. There were school nurses who may have diagnosed a student with hundreds of nits. If that child returned to school with even one nit remaining the child had to go home. Then there were nurses who would take the time to pull out a couple of nits if that was all that remained in the hair.

Schools Continue to Drop “No Nit” Lice Policies  

Today the “no nit” policy is being dropped in more and more schools. So why is this and how does it affect your children? Well, the lice policy is determined by each school district or even at the individual school level.

The CDC, the American Academy of Pediatrics, and the National Association of School Nurses have endorsed a relatively recent policy which allows children to return to school with nits in the hair if no lice are present, because lice do not spread disease. In their opinions, too much school was being missed to the detriment of your child. And, yet, while it is true that lice do not spread disease, the evidence on how risky it is to allow your child to return to school with nits in their hair has yet to be proven. The evidence points both ways. Source: nydailynews.com  

Against Dropping “No Nit” Policies

In order to ascertain that there are no live lice in the hair, you really need to do a thorough search of the hair. Lice are extremely fast and agile when moving through your hair and even professionals can’t rely on a visual inspection unless it is an extremely advanced case. Lice are very sensitive to light and movement, and they camouflage well in all colors of hair. This means that some students who appear to have nits only, may, in fact, be harboring bugs. School nurses only have the time to do a cursory search for lice; because of other demands on their time, they cannot apply oil and do a thorough search to find out if there are live lice in the hair. The nurse may not see live lice in the hair but that doesn’t mean that they aren’t there. 

As a matter of fact,hendersonville identify what nit lice egg look like bugs present studies have shown in controlled tests that up to 80% of the time where it was thought that only nits were present, after combing by a professional, there were, in fact, live lice in the hair after all. Through years of experience, we at LiceDoctors have learned just how quickly lice spread from one person to the next, and one thing is certain: if your child has eggs in their hair, then at some point, there were live lice in their hair. Statistics show they probably still are there. For sure the nits are there. As a technician for LiceDoctors, I can’t tell you how many times I have combed someone’s hair and it took me a good 20 minutes to finally find the lice that had laid these eggs in your child’s hair. However, without a doubt, had I not found that female louse, I know for certain that lice would have spread through your house very quickly. 

The implication of this is clear: if you drop a “no nit” policy and allow children into school with nits only, you may inadvertently allow students with live lice into the classroom. What is the difference between live lice and nits with regard to the transmission of lice? Only live lice are contagious.  You cannot transmit nits to another person. So when you get rid of the school “no nit” lice policy, you are likely making it possible for students with lice to be in the classroom.

“The National Pediculosis Association, recommends the No Nit Policy as the public health standard intended to keep children lice free, nit free, and in school...The Spirit of the No Nit Policy is to minimize head lice infestations as a public health problem and to keep children in school lice and nit free.”  https://www.headlice.org/comb/what-are-head-lice-and-nits/no-nit-policy/

If you have spent a lot of time and money on prescription lice treatments, lice killing kits, and/or professional lice treatment and you have finally gotten rid of lice, do you want a child with an active case sitting next to your child?

In Favor of Dropping “No Nit” Policies

The American Association of Pediatrics (AAP), the National Association of School Nurses (NASN), and the Centers for Disease Control (CDC) all advocate that "no-nit" policies should be discontinued. Some of the reasons are as follow:

  • Lice are a nuisance; they are not dangerous nor do they carry disease.
  • The policy causes unnecessary school absenteeism, and the downside of that far outweighs the risks associated with head lice.
  • Misdiagnosis of nits is very common during lice checks conducted by non-medical personnel. Some students with debris or dandruff are sent home due to human error in diagnosis.
  • Many nits are more than ¼ inch from the scalp. These eggs are not viable and are very unlikely to hatch to become crawling lice, or may in fact be empty shells, also known as casings. These are sometimes mistaken for viable nits.
  • Nits are glued to hair strands and cannot be transferred successfully to other people. This is very important. Nits are not contagious and there is no reason for students to miss school if they only have nits,
  • It usually takes about 4-6 few weeks for a case of head lice to be diagnosed and during that time the child has been in contact with other children. Basically, a “no nit” policy is a case of too little, too late.

The AAP policy states that since a child with head lice has likely had the case for over a month by the time it is uncovered, the child should be allowed to stay in school with the caveat that he or she should not be in direct head to head contact with others. The child’s privacy should be maintained and the parents should be apprised and advised to treat the child. Many research scientists state that “no-nit” policies should be dropped as students should be in school.

More and More Schools Recommend that Parents Conduct Head Lice Checks

While it is less likely now that your child will be sent home from school due to head lice and/or nits, you do  want to discover a lice case before it is advanced. It is important for you to know your school’s lice policy.
