Clinical Services

The Clinical Services team at St. John’s School provides traditional school health services to our student body. In addition, partnering with parents and primary care physicians, additional services are offered such as flu vaccinations and rapid strep testing, to keep students in the classroom and maintain a healthy and productive student body. The Clinical Services team works to improve each student’s health by providing the following:

  • Administration of first aid, treating minor medical problems and identifying community health concerns.
  • Identifying the need for referral to our counselors for social and emotional problems
  • Monitoring communicable disease outbreaks in the community to minimize the impact on our student body.
  • Working with students and their families with chronic health conditions and communicating medical needs or changes to those involved in the care of that student.
  • Health and wellness education that supports a healthy lifestyle.

Injuries & Illnesses

Should your child be ill or injured please communicate this with the Clinical Services team. This helps us track our illnesses and make sure our community stays well along with communicating your child’s needs with other departments should they need accommodations.

Enhanced Clinical Services

While it is the School’s intention for the first point of contact to be with one’s primary care doctor, these expanded services will provide added convenience for our community as it relates to identifying illness in order to limit time out of the classroom and proactively prevent the spread of communicable diseases. These services are not intended to replace the care and guidance of a primary care physician, but rather will assist in times of need when an appointment with a primary care doctor is not feasible. The SJS Clinical Services Department is now a licensed lab with the State of Texas to perform limited screenings.
