CLB Assessment Belgium: What to Expect and How to Prepare

You've received a letter saying the CLB will be involved in your child's assessment. Or the school suggested contacting the CLB about your child's learning difficulties. Either way, you need to understand what this body actually is, what it can do, and how to walk into that meeting prepared.

For English-speaking families in Belgium, the Centrum voor Leerlingenbegeleiding is the single most consequential institution in your child's school life. Every significant support decision — from unlocking specialist in-class help, to authorizing an individual curriculum, to paving the way for special education placement — runs through the CLB.

What the CLB Is

The Centrum voor Leerlingenbegeleiding is an independent, multidisciplinary guidance center attached to every Flemish school. It is staffed by physicians, nurses, social workers, psychologists, and pedagogues. The CLB operates separately from the school itself — it reports to the Flemish Ministry of Education, not to the school board — which gives it a degree of independence in its assessments.

Every Flemish school is linked to a specific CLB. You cannot freely choose a different CLB; your child is assessed by whichever center is attached to their school. CLB services are entirely free of charge.

The CLB serves four core functions: health guidance, psychosocial guidance, learning guidance, and career guidance. For children with SEN, you'll primarily interact with the learning guidance and psychosocial guidance functions.

The CLB's Role in the Zorgcontinuüm

The CLB does not get involved at the first sign of difficulty. Flemish schools are legally required to work through a phased framework called the Zorgcontinuüm before formally engaging the CLB:

Phase 0 (Brede Basiszorg): The school provides differentiated learning for all students — universal design, prevention of learning gaps. No CLB involvement required.

Phase 1 (Verhoogde Zorg): The school's internal care team implements specific documented measures: extra time, text-to-speech software, small-group instruction. Still no CLB.

Phase 2 (Uitbreiding van Zorg): When Phase 1 measures are insufficient, the school formally involves the CLB. This triggers the CLB's specialized diagnostic trajectory, known as the HGD-traject (Handelingsgericht diagnostisch traject). The school continues Phase 1 accommodations while the CLB evaluates.

Phase 3 (Individueel Aangepast Curriculum): If the CLB determines the mainstream curriculum is no longer feasible, they issue a report authorizing an individual adapted curriculum or recommending special education placement.

This phased structure means that by the time the CLB is formally engaged, the school should already have documented evidence that basic and increased care measures were insufficient. If a school tries to jump directly to CLB referral without documenting Phase 0 and 1 interventions, parents can ask what internal measures were taken first.

What the CLB Assessment Involves

The CLB assessment (HGD-traject) is comprehensive and typically involves multiple sessions. Expect:

• Observation sessions in the classroom
• Psycho-educational testing: standardized cognitive assessments, academic skills tests, and sometimes neuropsychological screening
• Parent interview: the CLB will interview you about your child's developmental history, home environment, and prior educational experiences
• Teacher input: the CLB collects formal input from the classroom teacher and internal care coordinator
• Medical review: the CLB physician may review medical history or request additional medical information

The process can take several weeks to several months. There is no fixed statutory timeline equivalent to the UK's 20-week EHCP process or the US's 60-day evaluation window.

The Three Key Verslagen: What the CLB Can Issue

At the conclusion of the HGD-traject, the CLB issues one of three legally binding reports. These verslagen are not recommendations — they authorize specific interventions and placements:

GC-Verslag (Gemeenschappelijk Curriculum Report): Confirms the student has specific educational needs but can continue following the mainstream curriculum, provided they receive targeted learning support and reasonable accommodations. This report unlocks funding for Leersteun specialists to assist the mainstream teacher. It is the "inclusive education with support" outcome.

IAC-Verslag (Individueel Aangepast Curriculum Report): Issued when the mainstream curriculum is no longer feasible even with maximum reasonable accommodations. It authorizes an Individual Adapted Curriculum — the closest Belgian equivalent to a comprehensive IEP. With an IAC-Verslag, parents retain the right to insist their child remains in a mainstream school. However, the school can legally refuse under an "ontbindende voorwaarde" (resolutive condition) if they can prove the required accommodations would be disproportionate to their capacity.

OV4-Verslag: A highly specific report for secondary school students who have the cognitive ability to earn a mainstream diploma but whose medical or psychiatric needs require the specialized environment of a BuO school to achieve it.

The distinction between GC-Verslag and IAC-Verslag is the most consequential decision the CLB makes. A GC-Verslag keeps your child in the mainstream curriculum. An IAC-Verslag does not necessarily mean special school, but it fundamentally changes the curriculum goals.

Reasonable Accommodations: What You Can Request

Under the Leersteundecreet, mainstream schools must provide redelijke aanpassingen (reasonable accommodations) for students with a GC-Verslag. Common examples include:

• Extended time on tests and examinations
• Use of text-to-speech or speech-to-text software
• Quiet room for assessments
• Modified homework volume
• Preferential seating
• Access to a reader or scribe
• Reduced writing load with alternative output formats
• Sensory breaks

The critical legal distinction: accommodations must not lower curriculum expectations. They help the student access the same curriculum as their peers. If the support required would fundamentally change what the student is expected to achieve, the CLB moves toward an IAC-Verslag rather than a GC-Verslag.

Schools cannot unilaterally refuse reasonable accommodations if a GC-Verslag has been issued. If a school is not implementing documented accommodations, you can formally request written explanation and, if necessary, escalate to the Commissie inzake Leerlingenrechten.

How to Prepare for a CLB Meeting

The CLB meeting — especially the parent interview during the HGD-traject — is a high-stakes interaction that most English-speaking families are underprepared for. Several practical steps reduce the risk of miscommunication or incomplete assessment:

Bring a complete developmental history in writing. The CLB relies heavily on documented developmental history to make placement determinations. A missing piece — a previous diagnosis, a therapeutic report from your home country, a school assessment — can result in delayed support or misplacement. Prepare a written timeline in Dutch or French if possible; if not, bring it in English and request a social translator.

Request a social translator in advance. CLB meetings regarding school placement are legally conducted in the operational language of the school (Dutch for Flemish schools). You have the right to involve an accredited social translator (sociaal tolk). Request one when you first contact the CLB — do not wait until the meeting day.

Bring all foreign documents, translated. A US IEP, UK EHCP, or international psychological assessment will not automatically be accepted, but the CLB may incorporate the clinical data if the assessment standards are sufficiently rigorous. Have documents translated professionally. Note that the CLB may still require a new Belgian assessment if they consider foreign diagnostics insufficient.

Ask the school what phases of the Zorgcontinuüm have been documented. Before the CLB meeting, get clarity from the school on what Phase 0 and Phase 1 measures were tried and recorded. This documentation is supposed to inform the CLB's assessment.

Prepare specific questions. You have the right to ask: What type of verslag will be issued? What is the timeline? If an IAC-Verslag is recommended, what are the implications for secondary school transitions? If the CLB recommends a BuO placement, what Type and what OV track is being proposed?

Know your appeal rights. The CLB issues a recommendation, but the final placement decision involves the school and parents. If a school refuses enrollment citing insufficient capacity, they must provide formal written justification. You then have 30 days to appeal to the Commissie inzake Leerlingenrechten.

The Belgium Special Education Blueprint includes a CLB meeting preparation protocol — covering what documents to organize, what questions to ask at each phase, and how to respond to the most common verslag outcomes.

If You're Coming from Another Country's SEN System

Foreign SEN documents carry no legal authority in Belgium. The CLB will review your home country's diagnostics during their assessment, but the Belgian administrative equivalents must be established through the local process. If the CLB accepts the underlying clinical data from a foreign assessment, they will issue the appropriate Belgian verslag. If not, your child undergoes a new evaluation.

This can feel like starting from scratch after years of hard-won documentation. But the CLB process, navigated with preparation, is not hostile — it is simply different. The families who fare best are those who arrive with complete, organized records and who understand what each phase of the process is designed to establish.
