The school nurse parent letter library
A school nurse writes more parent correspondence than anyone else in the building except the attendance clerk, and gets less help with it than anyone at all. This is the index: what each letter is for, who receives it, whether you may name the child, and which body of law decides that — federal privacy law, state communicable-disease law, or nothing but district policy.

The "Published" column is honest about what exists on this site today. Rows marked Planned are written and queued, not live; we would rather show you the shape of the whole library than pretend the gaps are not there.
Which letter do I send? Four questions, in this order
Nurses rarely get the letter wrong. They get the category wrong — they send an individual-family letter to a class, or a class notice to a school, or a clinical letter where a policy letter was needed. Work down these four questions and the category resolves.
- Is there an identified child at the centre of this? If yes, and the letter is going to that child's own household, you can say everything you know. If yes, and the letter is going to anyone else, you must write the entire letter without the child being identifiable — and "identifiable" includes the combination of details, not just the name. See FERPA vs HIPAA.
- Does the condition carry a legal reporting duty? Some conditions oblige the school to notify a health authority, and in several the health department — not the district — directs the parent notification. Measles is the clearest example. If a reporting duty exists, the phone call to the health department precedes the letter, not the other way round.
- Is exclusion involved? Exclusion changes a letter from correspondence into a decision with consequences: lost instruction, an attendance code, and sometimes a due-process obligation. Immunization exclusion is the sharpest case. See immunization exclusion letters.
- Is the recipient one household or a group? This decides your channel as much as your wording. An individual clinical letter should not be a mass text. A class-wide exposure notice should not be a paper letter in a backpack that surfaces on Thursday.
A fifth question worth adding for the whole library: would you be comfortable if this letter were read aloud at a board meeting, or forwarded to a local reporter? Health-office correspondence gets forwarded more often than any other district communication, because it frightens people. Write to the forwarded version.
The six blocks in every exposure letter, and the three that cause trouble
Every classroom or school-wide exposure notice, whatever the pathogen, is the same six blocks in the same order. Once you have the skeleton, a new condition is a twenty-minute job rather than an afternoon.
- What happened, stated plainly and without a name. "A case of X has been confirmed in your child's classroom." Not "we have been made aware of a situation."
- What the condition is, in two sentences. Written for a parent who has never heard of it, without a paragraph of virology.
- What to watch for, and by when. Symptoms and the outside edge of the incubation window, so a family knows when to stop worrying.
- What to do if symptoms appear. Concrete: call the provider, keep the child home, tell the health office.
- What the school is doing. Cleaning, health-department contact, monitoring. Families forgive a lot if they can see the school acting.
- Who to call, with a real name and a real number. Not "contact the school office."
The three blocks that get districts into trouble, all of which appear in widely-copied templates:
- Reassurance you cannot support. "There is no risk to other students" is not yours to say, and if a second case appears it is the sentence that gets quoted back to you.
- Clinical direction beyond your licence. A letter that tells families which medication to buy, or that a condition "does not require a doctor", is practising outside the school health role. Describe thresholds for seeking care; do not prescribe.
- Detail that re-identifies the child. Room number plus date of detection plus "the student is in the afternoon kindergarten section" is a name in every practical sense. A small school is a small denominator.
Channel: which of these may never be a text message
The health office has three channels available in most districts — paper, email, and SMS or voice — and the decision is not about convenience.
- Never SMS alone: any letter naming a diagnosis for a specific child, any exclusion notice, any screening result, any injury notification more serious than a scraped knee. A text is a poor evidentiary record, it lands on a device that may be shared, and it cannot carry the detail a family needs to act.
- SMS is the right first channel: outbreak notices where speed matters, forms reminders, screening-day logistics, medication-pickup reminders. Use it to tell a family a letter exists, and to get a reply.
- Voice earns its keep in households where reading English is harder than hearing it, and for anything you would otherwise phone about one household at a time. A sixty-second recorded call reaches four hundred families in the time it takes to make nine calls.
- Paper is still required where a state code specifies a delivery method, and for anything that may end up in a due-process file.
Districts consistently over-use paper for outbreak notices, where it is too slow, and over-use text for clinical letters, where it is too thin. Getting those two right is most of the improvement available.
What a comms platform can and cannot do for the health office
Kastr is a school-to-home communications platform, not a health record. It sends SMS, email and voice. It does not send push notifications, it does not carry attachments, and it does not hold a health record or an immunization roster.
The limitation that matters most to a nurse. Kastr resolves two audiences: specific people, and everyone in the district. There is no classroom, grade, school or bus-route preset — selecting a grade level or a single school is not something you can do today. A classroom exposure notice therefore has to be built by selecting that classroom's students, at which point their guardians expand automatically. That works, and for a class of twenty-four it takes about a minute, but it is manual and you should price that in. If your requirement is "pick 4th grade at Lincoln from a menu", we do not do it and you should weight that heavily.
What is genuinely useful here: a cost-and-reach preview before you send, so you can see what a district-wide voice call costs before you commit to it; a translation preview so you can read the Spanish before a family does; send-test-to-me so the merge fields get checked by a human; and scheduling with the audience resolved at send time rather than schedule time, so a Friday-evening notice queued on Thursday does not go to a roster that has since changed. Every send writes to a per-district append-only audit log whose entries are chained with SHA-256, which is a materially better exhibit than "we think it went out on the 14th."
Questions people actually ask
Can a school nurse name the sick student in a letter to other parents?
No. A student's health condition, held by the school, is an education record under FERPA, and disclosing it to other parents is not one of the permitted exceptions. The health-or-safety emergency exception is narrower than it sounds — it permits disclosure to people in a position to protect the student, such as public health authorities and emergency responders, not to the general parent body. Write the notice so that no combination of details in it identifies the child, and remember that room number plus date plus one more detail is often enough in a small school.
Do these letters need to go to the district's legal counsel before sending?
Routine class notices, no. Anything that excludes a student, alleges anything about another student, follows a serious injury, or departs from board policy, yes — and the review should happen before the first one goes out, not before each one. The efficient pattern is to have counsel approve the template and the decision rule once a year, so the nurse is applying an approved rule at 7am rather than waiting for a callback.
Which of these letters must legally go home on paper rather than by text or email?
That is set by your state code and by district policy, and it is usually specified for exclusion notices and for anything with an appeal right attached. Most exposure and screening letters have no specified method. The safe operating rule: if the letter changes a student's access to school, send paper and keep the delivery evidence, and use text or email only to tell the family the letter is coming.
How do I adapt a template when my state's exclusion rule differs from CDC guidance?
Your state health code and your local health jurisdiction win. CDC and AAP publish clinical guidance; states publish enforceable rules, and several still carry exclusion periods that are more conservative than current clinical guidance. Write the letter to the rule you are actually bound by, and if you think the rule is out of date, that is a policy conversation with your school health services lead and your board — not something to resolve inside a parent letter.
How many letters does a health office actually send in a year?
It varies enormously with staffing model and grade band, but the shape is consistent: two or three large all-household mailings, a heavy immunization sequence concentrated in the first six weeks, screening notices and results for two to four grade levels, and then a long tail of individual letters that dominates total volume without ever appearing in a communications plan. That tail is why the format of these templates matters more than their existence.
