The IEP Equivalent in Spain: Understanding the ACI (Adaptación Curricular)

The first question almost every expat parent asks is: "What is the IEP equivalent in Spain?" It is a fair question, and the honest answer is nuanced — Spain has an equivalent, but it works differently, carries different legal weight, and comes in two completely different forms that determine your child's academic future in fundamentally different ways.

The document is called the ACI — Adaptación Curricular Individualizada — and understanding the distinction between its two tiers is one of the most important things a parent can know before entering a school meeting.

What the ACI Is

The ACI (Adaptación Curricular Individualizada) is the individualised curriculum plan that a Spanish school develops for a student once their needs have been formally assessed and documented. It is the operational document that translates the state's Dictamen de Escolarización into classroom practice — specifying what modifications the student will receive, how they will be assessed, and what goals they are working toward.

Where the ACI differs from a US IEP or UK EHCP is legal enforceability. A US IEP is federal civil rights law; specific service minutes are legally binding, and parents have immediate recourse to due process if they are not delivered. A UK EHCP places a statutory duty on the local authority to secure the exact provision specified. The Spanish ACI is an internal administrative document of the regional education authority. It does not carry the same immediate, punitive legal enforceability — parents who find the ACI is not being followed must navigate Spain's administrative complaint system, which is slower and less directly coercive.

That said, the ACI is not without teeth. A Dictamen-backed ACI represents an official commitment by the state, and the Education Inspectorate (Inspección Educativa) can be engaged if a school is systematically ignoring its obligations.

The Critical Split: Significant vs. Non-Significant

This is where most expat families are surprised — and where the stakes are highest. ACIs exist in two completely distinct legal and pedagogical forms, and the difference between them affects your child's academic trajectory for years.

ACI No Significativa — Non-Significant Adaptation

A non-significant ACI applies to students who do not need their core curriculum objectives changed. The adaptation modifies how the student learns and how they are assessed, without altering the fundamental level of what they are expected to achieve.

Common non-significant adaptations include:

• 25% extra time on exams and written tasks
• Use of a laptop or keyboard for written work
• Oral examinations instead of written ones
• Sitting in a preferred location in the classroom (near the front, away from distractions)
• Enlarged text or different font formats for students with visual processing difficulties
• Reduced volume of written work without reducing conceptual content

Students who receive only non-significant ACIs are completing the standard national curriculum. They can proceed toward the standard graduation qualification (Título de Graduado en ESO) without restriction. Dyslexia, ADHD without severe behavioural comorbidities, mild anxiety — these typically receive non-significant ACIs.

ACI Significativa — Significant Adaptation

A significant ACI is reserved exclusively for students with an official NEE designation — that is, students whose needs arise from a recognised disability, autism spectrum disorder, or severe disorder. It modifies the core objectives, evaluation criteria, and essential curriculum content of the national programme.

The implication is serious: a student receiving a significant ACI in secondary education (ESO) is not completing the standard state curriculum. In high school, this typically means they cannot receive the standard Título de Graduado en ESO upon completion. This has downstream consequences for university access, which requires the standard EBAU/Selectividad exams.

LOMLOE has introduced alternative graduation pathways and diversification programmes designed to keep more students on broadly equivalent tracks, but parents should understand that accepting a significant ACI is a decision with long-term educational implications — not just an accommodation for the current year.

The PTI: The Execution Document

Some autonomous communities use a secondary document alongside the ACI called the PTI (Plan de Trabajo Individualizado). Where the ACI defines the broad curricular strategy and modifications, the PTI is the granular, term-by-term operational plan. It specifies the exact pedagogical strategies teachers will use, the short-term learning goals for each subject, and the specific interventions scheduled for the student.

If your child's school uses a PTI, you should request to see it at the beginning of each term and at any review meeting. It is the document that shows whether the ACI's commitments are actually being implemented.

Who Writes the ACI

The ACI is written by the teaching team, under the coordination of the school's Orientador (educational psychologist). The specialist staff assigned to the student — the PT teacher for special education support, the AL teacher for speech and language — contribute their sections. Parents do not typically co-author the ACI the way they would in a US IEP meeting, where parent input is a mandated part of the process.

Parents do have the right to be informed of what the ACI contains, to request to review it, and to raise concerns through the Orientador. If you want changes to the ACI, the most effective route is usually a formal meeting with the Orientador and tutor, with your concerns documented in writing.

Getting the ACI Updated

An ACI is not permanent. It should be reviewed at least annually and should be updated when the student's circumstances change significantly — a new assessment, a change of teacher, a significant regression or acceleration in progress.

If you believe your child's ACI has become outdated or no longer reflects their needs, you can request a formal review through the Orientador. If the school is unresponsive, the Inspección Educativa is the appropriate escalation point.

For Expat Families: The Translation Problem

If your child has a US IEP, here is a useful rough mapping:

Knowing this vocabulary means you can ask the right questions in meetings: "¿Tiene mi hijo una ACI no significativa o significativa?" — Does my child have a non-significant or significant ACI? — is one of the most important questions you can ask.

The Spain Special Education Blueprint includes a full Spanish-English terminology glossary and meeting preparation checklists for ACI review meetings, EOEP sessions, and Dictamen discussions.

The Bottom Line

The ACI is functionally Spain's IEP — but the absence of the same punitive legal enforceability means advocacy requires a different strategy. Know which type your child has. Know what it commits the school to delivering. And review it every year to make sure it still reflects where your child actually is.
