Please refer to the Katy ISD Health Services policy in
regards to head checks:
Head Lice are not a public threat, they do not carry communicable disease. The Texas Department of
State Health Services does not track cases of head lice in schools. Currently, the district recognizes that an
active head lice infestation may create a difficult learning environment for the affected student(s) and as a
result, the district maintains a program to identify and eliminate live head lice.
Head checks are made whenever symptoms are noted to be present. Parents are notified immediately if
their children have evidence of live head lice. Parents are encouraged to promptly pick up their child and
treat the condition. If the parent cannot come for his/her child, the telephone number of a relative,
neighbor, or friend who can come must be on file in the school office. Parents should contact their
medical provider for methods of treatment.
A parent should accompany the child to school upon his return. The child must report to the clinic before
going to class and is not cleared to return to class until his or her head has been rechecked by the nurse
and found to be free of live lice. If any live lice are found, in the child's hair, he/she will be sent home until
no evidence of live lice exists. Nit removal, though tedious, is the most effective way to eliminate lice.
Thank you for your help and cooperation, so that your child's education will not be interrupted. The most
effective screening occurs at home.
CHECKING FOR HEAD LICE Examine the entire scalp. Look for nits stuck to the hair shaft, as well as an adult louse moving around on the scalp or hair. Head lice and nits are about the size of a grain of rice. Nit Identification: Nits are lice eggs. They are white or tan in color when first laid. The nits turn coffee colored before they hatch. Nits are glued by the female louse on the hair shaft about 1/2 inch from the scalp. This glue is so strong that the nits cannot be as easily removed as dandruff. They cannot be washed or brushed out of the hair. Head Lice Identification: Adult and immature louse look similar. Adults are 1/10th to 1/8th inches long. They vary in color from tan to grey white. They cannot fly or hop, but crawl quickly. .
