School nurses surveyed by Penn State Health have offered families a set of back-to-school health recommendations, and the first two carry more weight than the rest: confirming that grade-required exams are actually done, and resetting sleep schedules before the first bell.
The guidance comes from Pennsylvania school nurses surveyed by Penn State Health and reflects their practical experience rather than trial evidence. It is professional judgment from people who see the consequences in September, which is a legitimate basis for advice and a different thing from a clinical study.
Required Exams Are Grade Specific and Vary by State
This is the item that trips up families every year, because the requirements are not annual.
In Pennsylvania, physical exams are required for students entering kindergarten, sixth and eleventh grade, and for all new students. Dental exams are required for kindergarten, third and seventh grade, and new students. Immunizations are required before kindergarten, seventh and twelfth grade, and for new students. Families can check the state health department's requirements page or ask the school nurse for a grade-level list.
Those specifics are Pennsylvania's. Requirements differ by state, and some states bar attendance without documented immunization. Do not assume the pattern above applies elsewhere.
The scheduling problem is predictable. Appointments compress into the last two weeks of August, waits lengthen and visits get rushed. Booking four to six weeks ahead is the standard recommendation, and if school has already started, the visit is still worth keeping rather than skipping. A child's primary care physician can complete the exam, and school nurses can recommend a provider for families who do not have one.
A sports physical is not the same as an annual well-child visit. A sports physical clears a child to play. A wellness visit reviews growth, development, vision, hearing, immunizations, nutrition, sleep and mental health, and it is where concerns a child has not voiced tend to surface.
Circadian Timing Shifts with Age, and Teenagers Get the Worst of It
The nurses' recommendation on sleep is simple: now is the time to move back toward a school bedtime and wake time, so children are accustomed to it in the first week rather than adjusting during it. The reason a reset takes weeks rather than one night is biological.
Sleep timing is governed by an internal circadian clock that adjusts gradually to light exposure and routine. A clock that has drifted two hours later over a summer of late nights does not snap back on command. Attempting to force it produces a child lying awake at the new bedtime and exhausted at the new wake time.
Adolescence complicates this. Puberty shifts circadian timing later, so teenagers naturally become sleepy later at night and wake later in the morning. That is a developmental change rather than laziness, and it collides directly with early high school start times.
Sleep need also varies by age. Children roughly 6 to 12 generally require 9 to 12 hours a night, and teenagers 8 to 10. Most American adolescents fall short during the school year. The consequences show up as things families do not connect to sleep: difficulty concentrating, irritability, emotional dysregulation, worse academic performance, higher injury risk in sports and increased vulnerability to illness. The nurses make the same link, noting that adequate rest supports focus, learning and the immune system.
Standard sleep guidance is to shift bedtime and wake time earlier by about 15 minutes every two or three nights rather than in one jump. Wake time is the more powerful lever, because a consistent morning wake time anchors the clock more reliably than bedtime does. Morning light exposure advances the clock, so getting a child outside shortly after waking helps, while screens in the hour before bed work against the goal. Keeping the schedule consistent on weekends matters too, since sleeping in three or four hours on Saturday undoes much of the week's adjustment.
The Four Recommendations That Get Less Attention
The rest of the list is unglamorous and specific.
Medication forms and emergency care plans must be submitted before the first day, not sent in with the child. Nurses ask parents to connect with them ahead of time so they are clear on a child's medical needs, medications and emergency plan, and to confirm current emergency contacts.
On diet, the nurses are direct about teenagers living on energy drinks and fast food, recommending protein, fruits, vegetables and whole grains instead, and saying to leave the energy drinks at the store. That advice lines up with warnings from poison control specialists about caffeine loads in adolescents and young adults.
On handwashing, the specific technique is 20 seconds of vigorous scrubbing with soap and water across the front and back of the hands. The nurses suggest humming "Happy Birthday to You" twice as a timer.
On staying home, the thresholds given are a fever above 100.4 degrees or vomiting or diarrhea. But the nurses also make the less common point that not every illness requires an absence. A mild headache or generally feeling off, without signs of contagion, may not warrant staying home, which preserves absences for when a child is genuinely ill.
Cost, Access and What to Bring
Barriers are real and often solvable.
Well-child visits and required immunizations are covered without cost sharing by most insurance plans as preventive care. For uninsured or underinsured children, the federal Vaccines for Children program provides required vaccines at no cost through participating providers, and Medicaid and the Children's Health Insurance Program enroll year-round rather than during a limited window. Many school districts and county health departments run back-to-school clinics offering physicals and vaccines free or at low cost. A school nurse can usually name local options.
Bring the school forms to the appointment rather than mailing them afterward. Bring a written list of concerns, including behavior, mood, sleep, eating, and any recent injuries or emergency visits, since visit time is short and the things parents mean to raise are the things that get forgotten.
Any child showing persistent difficulty sleeping, significant anxiety about returning to school, or a marked change in mood should be discussed with a clinician rather than waited out. Penn State Health has separately addressed how families can help children manage back-to-school anxiety.
Frequently Asked Questions
When should we start adjusting sleep? School nurses say now. Standard guidance is to shift bedtime and wake time by about 15 minutes every two or three nights.
How much sleep do children need? Roughly 9 to 12 hours for ages 6 to 12, and 8 to 10 hours for teenagers.
Why is it harder for teenagers? Puberty shifts circadian timing later, so adolescents naturally fall asleep and wake later.
Which grades require physicals? It varies by state. In Pennsylvania, kindergarten, sixth and eleventh grade, plus new students. Check your own state's rules.
Is a sports physical enough? No. It clears a child to play but does not cover growth, development, vision, hearing, immunizations and mental health.
When should a child stay home? The thresholds given are a fever above 100.4 degrees, vomiting or diarrhea. A mild, non-contagious complaint may not require an absence.
What if we cannot afford a visit? Preventive visits and vaccines are covered by most plans. The Vaccines for Children program, Medicaid, CHIP and county clinics offer no-cost or low-cost options.
