Finnish Pedagogy vs the American RTI Model

Response to Intervention, now often folded into Multi-Tiered System of Supports (MTSS), is the main framework US schools use to catch and support struggling learners. Finland has run its own multi-tiered support model since 2011, and comparing the two shows where the underlying idea, catching problems early and matching support to need, plays out differently in practice.

How RTI and MTSS work in US schools

RTI is built around universal screening of all pupils, early intervention for those who show signs of difficulty, frequent progress monitoring, and increasingly intensive, research-based instruction for pupils who do not respond to lower tiers of support. It is typically described in three tiers: whole-class, high-quality instruction for everyone; small-group intervention for pupils who need more; and intensive, individualised intervention for pupils who need the most.

MTSS is the wider umbrella term now used in many US states, combining the academic focus of RTI with a parallel system for behaviour support. In practice, a pupil's progress through the tiers, and sometimes their eligibility for special education, is closely tied to data from formal assessments and progress-monitoring tools.

Finland's tiered model, and the philosophy behind it

Finland's three-tier support model shares the core logic of RTI: start with support available to everyone, increase intensity for pupils who need it, and involve specialists as needs grow. But it grew out of a different starting point, Finland's long-standing commitment to inclusive education and to keeping pupils in mainstream classrooms wherever possible.

A key philosophical difference is that in Finland, a formal diagnosis or eligibility assessment is not usually a precondition for a pupil to receive extra help. If a teacher notices a pupil struggling, support can begin straight away, coordinated through discussion between the teacher, the special education teacher and, where relevant, the pupil's family, rather than through a formal testing gateway.

Where the two systems differ most

Comparative research examining maths support in both countries found that the systems' biggest divergence is not in their tier structure, which is broadly similar, but in how assessment and instruction operate inside each tier. US practice tends to lean more heavily on standardised, norm-referenced testing to decide movement between tiers and to establish eligibility for special education. Finnish practice leans more heavily on teacher judgement, ongoing classroom observation and formative assessment, supported by targeted screening rather than high-stakes testing.

Class size and staffing structures also shape how each system feels in practice. Finland's comparatively small class sizes and strong teacher autonomy mean more support can happen inside the ordinary classroom before a pupil is pulled out for separate intervention, which is a more common pattern in some US RTI implementations.

A note on Finland's 2025 reform

In August 2025, Finland's Parliament replaced the three named tiers, general, intensified and special support, with a reformed model built around group-specific and student-specific support measures. The change followed concern that too many pupils, around a quarter by 2024, were ending up in the more intensive tiers, more than the original 2011 reform had anticipated. Under the new model, schools are expected to deliver more support directly within the regular class group, with teachers managing a capped number of pupils needing support in any one group and individualised measures such as remedial teaching offered more readily during school hours.

For the purposes of comparing with US RTI and MTSS, the underlying principle Finland is keeping, matching support intensity to need, intervening early, and avoiding unnecessary separation from peers, remains intact even as the tier labels themselves have changed.
