  • Avoid close contact with others who are sick or are beginning to display symptoms

  • Stay home if you feel sick and see a doctor as soon as possible

  • Fever of 100.0 must remain home and stay home for at least 24 hours without the use of fever reducing medication

  • Cover your mouth and nose with tissues when coughing or sneezing

  • Wash your hands thoroughly and frequently with antibacterial soap to kill and avoid spreading germs

  • Avoid touching eyes, nose and mouth as germs and bacteria can enter this way and cause illness. 



Your child is required to be up to date on all immunizations in order to attend school. If or when it is found that your child is or will be behind on a vaccination, the nurse will send a note home, so be sure to check their take-home folder daily. There are many resources in the community that offer free or reduced-cost vaccination clinics. Please call the nurse to find out about these opportunities.
If you choose not to vaccinate your child, you must turn in a notarized, original state-issued affidavit for “Reasons of Conscience” to the clinic.



Katy ISD policy requires that students with vomiting, diarrhea or fever of 100 degrees or greater MUST stay home. They must remain at home until symptom-free for more than 24 hours without the use of medications, such as Tylenol, Motrin, Immodium, Pepto Bismol, etc. If your child has been diagnosed with an infection disease (ex: Chickenpox, Measles, strep throat, pink eye, lice, etc.), please notify the nurse as soon as possible.



If they have been injured and must refrain from strenuous physical activity, it is the parent’s responsibility to send a note to school to excuse the child from PE or recess.  



Students may NOT carry medication with them at school. All medication must be turned into the nurse in its original packaging and must be accompanied by the district Medication Permission form . Click the link below for the forms.

Nurses Notes

Every child should eat a well-balanced breakfast before class every day to help them remain focused on class work.

Each student should have a change of clothes in their backpack, including socks, in case of accidents or emergencies. We also accept donations of clothing.

Please make sure your phone numbers and emergency contact numbers are updated regularly, so we may contact you immediately if your child becomes ill.

Allergy season is a year-round phenomenon in Houston. Symptoms include sneezing, itching, watery eyes, and coughing that can lead to vomiting. To prevent symptoms from worsening and turning into an infection, please make sure your child is sufficiently medicated on a daily basis before arriving at school in the morning. Refer to the Quick Links box to the right for Daily Pollen Counts for Houston.
