Frankfurt's International Schools Aren't Exempt From the Measles Vaccine Rule Either

The Official Rule

Frankfurt hosts one of Germany’s heaviest concentrations of private and international schools, a direct consequence of its finance-sector and EU-institution employer base. Frankfurt International School (FIS) in Oberursel, ISF International School Frankfurt Rhein-Main in Sindlingen, Strothoff International School in Dreieich, Metropolitan School Frankfurt inside the city itself, and the tuition-free-for-EU-staff Europäische Schule Frankfurt all draw families who assume, understandably but wrongly, that operating outside the German state school system means operating outside the country’s public-health vaccination rules too. It doesn’t, and it’s worth correcting before it turns into an unwelcome surprise at enrollment.

The type of school has zero bearing on whether Germany’s measles proof requirement applies. bussgeldkatalog.org’s legal explainer on who the school-based measles requirement covers states plainly that the requirement applies equally to private schools, Waldorf schools, and public schools alike. What actually determines whether the rule applies is whether the child is fulfilling compulsory education (Schulpflicht) at that institution, not who owns, funds, or runs it, and not whether the curriculum is IB, SABIS, or the standard Hessian one.

What’s actually worth understanding is the consequence structure, which is the same across every school type, not a private-school carve-out. A school-obligated child can’t be turned away or excluded from attendance solely for missing measles proof, because compulsory education (Schulpflicht) overrides that restriction, this holds true whether the school is public, private, Waldorf, or international. But the requirement itself doesn’t simply vanish: the school is still required to notify the Gesundheitsamt (health department) about the missing proof, regardless of the school’s ownership structure, and from there, a fine of up to 2,500 euros for parents remains a real possibility that the health department can pursue on a case-by-case basis.

If you’ve assumed your family is outside this requirement because of Frankfurt’s specific international school landscape, it’s worth correcting that assumption before enrollment rather than after. The proof requirements, deadlines, and documentation process work identically whether you’re enrolling at a neighborhood Grundschule or at FIS, ISF, Strothoff, MSF, or the Europäische Schule Frankfurt.

What Real People Say

The specific misconception that Frankfurt’s international schools sit outside German public-health requirements comes up often enough among relocating families that it’s worth addressing directly rather than assuming it’s a rare misunderstanding. It also shows up, in a quieter form, in the schools’ own paperwork: ISF International School Frankfurt Rhein-Main’s own enrollment documents page lists a student medical form among the standard documents required to enroll, alongside the enrollment contract, a copy of the birth certificate or passport, and prior school reports, exactly the kind of health documentation a public Hessian school would also expect, not something FIS, ISF, Strothoff, or MSF treat as optional because of their independent, internationally accredited status.

The practical lesson that emerges is treating any Frankfurt school, regardless of type, whether it’s a public Grundschule, a Waldorf school, or one of the region’s well-known international names, as subject to the identical measles documentation requirement from the start of the enrollment process, rather than discovering the requirement applies only once paperwork is already underway.

Step by Step

1. Don’t assume FIS, ISF, Strothoff, MSF, or another Frankfurt private or international school sits outside Germany’s measles proof requirement, it doesn’t.
2. Prepare the same documentation, vaccination proof or a doctor’s immunity certificate, regardless of the school type you’ve chosen.
3. If proof is genuinely missing, understand that attendance still can’t be refused, since compulsory education overrides that, but expect the school to notify the Gesundheitsamt regardless of its private or international status.
4. Don’t assume a fine is off the table because the school is privately run, the health department’s enforcement track applies the same way.
5. If your school’s enrollment materials don’t explicitly mention this requirement, ask directly, rather than assuming its absence means it doesn’t apply, and expect a student medical form to be part of the standard paperwork either way.

Compliance Note

This page clarifies that Germany’s measles proof requirement under the Masernschutzgesetz applies identically regardless of school type, current as of mid-2026. It is not legal advice. For your specific school’s enrollment requirements, confirm directly with the school and, if needed, Frankfurt’s Gesundheitsamt.
