International Schools in Frankfurt for Special Needs: What SEN Support Actually Costs

Most expat families arriving in Frankfurt with a child who has special educational needs ask the same first question: can we just put them in an international school? The answer is: possibly, if the needs are mild, if the school judges it can manage, and if the budget allows. For everyone else, the German state system is unavoidable, and understanding how it works is not optional even if you start with a private school placement.

What Frankfurt's International Schools Actually Offer

Frankfurt has a cluster of established international schools, each with different curricula, different SEN provision levels, and very different price points. The key distinction for families with special needs children is the gap between what the brochures describe and what actually happens when a child's needs are more complex than mild.

Frankfurt International School (FIS): One of the most prominent international schools in Germany, offering IB and American curriculum. FIS explicitly states on its website that its Learning Support services accommodate students with mild learning difficulties. Students with moderate to severe needs are regularly not admitted, or not offered renewal after enrollment. Tuition runs from €11,590 per year at the early years level to €31,365 per year at grades 11–12. This does not include SEN surcharges, which are billed separately and not quantified in the standard fees schedule. Capital assessment fees of €6,600 plus a €1,500 registration fee apply on enrollment.

ISF International School Frankfurt Rhein-Main: Operates on a "case-by-case" admission model for special needs students. The school assesses each child individually to determine whether it can provide adequate support. Baseline tuition runs from €14,850 (Kindergarten) to €24,210 (Grade 13). A €6,000 place reservation fee is spread over the first three years, plus a €600 enrollment fee. What learning support will actually cost on top of this is not published.

Metropolitan School Frankfurt (MSF): Tuition from €13,440 to €21,460. Offers targeted EAL and language support, which primarily addresses language acquisition rather than disability-related learning needs. Students with significant SEN beyond language support may find the provision insufficient.

Strothoff International School: Explicitly states in its fee schedule that specialist therapy and "additional learning support beyond normal provision" will be invoiced as additional costs beyond the base tuition. This is at least transparent — but it underscores that there is no cost ceiling for SEN support at private international schools.

Phorms Bilingual School Frankfurt: Operates as a state-approved bilingual school following the Hessian curriculum alongside Cambridge/IGCSE. Because it follows state curriculum, it integrates smoothly with Hessian legal frameworks. This is the most seamless option for families who want an English-language environment but also want access to the legal protections of the German state system.

The Fundamental Problem: No Admission Guarantee

Private international schools are not bound by the inclusion obligations that govern state schools under HSchG § 51. They can refuse admission, and they regularly do for children with complex needs.

The realistic profile for a child who will be admitted to most Frankfurt international schools with SEN: mild to moderate dyslexia, well-managed ADHD, high-functioning autism without significant behavioral presentations. Children who require dedicated one-on-one paraprofessional support, intensive behavioral management, physical accessibility accommodations, or specialized curriculum modifications are frequently declined.

This is not a criticism of these schools — they are operating within their stated capacity. It is a warning that treating international school enrollment as a guaranteed escape route from the German state system leads families to make financial commitments (including substantial non-refundable enrollment fees) before discovering the child will not be admitted or that the support on offer is wholly insufficient.

What International Schools Cannot Do That State Schools Can

Under the German state system, a child with a formally recognized SPF is legally entitled to: a Förderplan reviewed twice yearly, BFZ special education teacher support, the right to request mainstream inclusion with appropriate accommodations, access to a Schulbegleitung funded through the welfare system, and a formal appeals process if any of this is denied.

Private international schools provide none of these statutory entitlements. Their SEN provision is entirely at the school's discretion — in terms of what is offered, how it is structured, what it costs, and whether it continues from year to year.

If a child enrolled in a Frankfurt international school requires more support than the school can provide, the family faces the same challenge they would have faced on day one: navigating the German state system, now with the added complication of mid-year transition.

The State System Remains Relevant Even for International School Families

Even families who successfully enroll in an international school should understand the Hessian state system for three practical reasons:

Financial sustainability. International school enrollment at the FIS or ISF level costs €25,000–€31,000+ per year in base tuition alone, typically without corporate subsidy for the SEN surcharge component. When the assignment ends or the corporate package changes, many families transition to state schools. Knowing the system is not optional preparation for that transition.

SEN escalation. A child admitted to an international school with mild learning support needs may, over time, develop needs that exceed the school's stated capacity. When that happens — often without warning — families need to move into the state system immediately, and they need to understand what the entry process looks like.

Schulbegleitung funding. If a child enrolled in a German-language program (including Phorms) qualifies for a Schulbegleitung under SGB VIII or SGB IX, the welfare-funded aide can in principle follow the child to any school, including a German-language private school. Understanding this means families do not have to choose between a preferred school setting and funded support.
