EHDAA Classification Codes and Funding in Quebec Schools

When your child's school mentions a "code" in relation to their EHDAA classification, they're referring to a specific MEQ administrative designation that determines how the province funds support services. Understanding which code applies — and which doesn't — is one of the most consequential pieces of knowledge a Quebec parent can have.

As of the 2023-2024 school year, 276,431 students are classified as EHDAA across Quebec's public and private networks. That's nearly 24% of the total provincial student population. These students aren't all funded the same way, and the code assigned to your child has a direct impact on what resources their school is entitled to request.

What EHDAA Actually Means

EHDAA stands for élèves handicapés ou en difficulté d'adaptation ou d'apprentissage — students with handicaps, social maladjustments, or learning difficulties. The designation covers a broad spectrum: from severe intellectual disabilities and autism spectrum disorder down to learning disabilities like dyslexia and mild ADHD.

This breadth matters because the system isn't uniform. Within EHDAA, there are two fundamentally different categories:

Students with handicaps — These students carry a formal MEQ disability code (see below). They typically have severe functional limitations identified by a professional evaluation. Their classification triggers specific "bridge funding" allocations to the school service centre.

Students with adaptation or learning difficulties — These students receive a PI and support services without necessarily carrying a formal code. They may be designated as "at-risk" (code 10 or 12), but their support is funded through base-level allocations rather than code-specific bridge funding.

The practical difference for parents: a student with a formal code often has more predictable, dedicated funding attached to their file. A student classified only as "at-risk" is funded from a general pool that schools must allocate internally — creating more room for budget-driven service cuts.

The 12 MEQ Disability Codes

Here are the primary MEQ codes currently in use:

Code 14 — Severe behavioural disorders (Troubles graves du comportement) Assessed by a psychologist or psychoeducator. Students with Code 14 often end up in specialized behavioural classrooms or alternative programming. This code is not assigned for garden-variety ADHD or oppositional behaviour — it requires demonstrated severe, persistent conduct issues that fall outside typical developmental variation.

Code 23 / 24 — Intellectual disabilities Code 23 covers profound intellectual disabilities; Code 24 covers moderate to severe. Both require psychological assessment. Students on these codes generally follow a distinct educational program rather than the standard PFEQ curriculum, and graduation pathways differ significantly from peers.

Code 33 — Mild motor or organic impairments Assessed by a physician or occupational therapist. Despite involving a physical impairment, 76.1% of Code 33 students are integrated into ordinary classrooms with physical accommodations rather than specialized placements.

Code 34 — Language disorders (dysphasia) This code covers severe language disorders assessed by a speech-language pathologist. It represents a large share of the EHDAA handicapped population. Code 34 triggers early intervention requirements; delays in SLP assessment directly delay eligibility for this code and its associated funding.

Code 50 — Autism Spectrum Disorders (TSA) Assessed by a multidisciplinary medical team. Code 50 is the most prevalent handicap code in Quebec, accounting for 44.4% of all EHDAA students with a handicap designation. It requires significant behavioural and sensory accommodations and is the classification most often associated with specialized classroom placement or intensive support aides.

Code 53 — Psychopathological disorders Applied for severe psychiatric conditions — diagnosed anxiety disorders, depression, psychosis — that materially affect schooling. Requires assessment by a psychiatrist or psychologist. This code is not assigned for stress or mild emotional difficulty.

Code 99 — Atypical or temporary deficiency Assigned while a student awaits a final diagnosis, or when their presentation is too complex for a single category. Code 99 is a transitional designation — it provides temporary funding coverage while the diagnostic process is ongoing.

The "At-Risk" Category: Codes 10 and 12

Code 10 (learning difficulties) and Code 12 (social maladjustment, mild) are administrative designations rather than formal disability codes. They cover students with general learning delays and mild ADHD — the single largest group within EHDAA.

The critical issue with codes 10 and 12 is that they don't trigger the same level of dedicated funding as the handicap codes above. Schools receive base EHDAA funding to serve these students, but allocation within that envelope is at the school service centre's discretion.

Parents of at-risk students frequently report that schools hesitate to allocate dedicated paraprofessional (TES) hours or one-on-one specialist support without a formal medical code. This is a known structural gap in the Quebec system — these students are entitled to a PI under LIP 96.14, but the actual services written into that PI depend heavily on what the CSS has available rather than what MEQ standards prescribe.

How EHDAA Funding Flows to Schools

The MEQ allocates funding to school service centres through a formula that includes base per-student funding plus additional code-specific amounts for handicapped students. The CSS then distributes this to individual schools.

Recent ministerial reforms have aimed to reduce the system's dependence on formal codes by providing base funding for "at-risk" students without requiring a medical diagnosis. In theory, this should reduce the diagnostic bottleneck. In practice, families consistently report that resources follow formal codes, and students without a code continue to receive fewer dedicated hours.

A related funding mechanism is Mesure 30810, which funds assistive technologies for EHDAA students. To access this funding, the technology must be named explicitly in the student's PI and identified as essential to their learning. The funding flows to the CSS and then to the school — but it only activates if the PI specifically calls for the technology.

Why Classification Battles Happen

Classification disputes between parents and schools typically fall into a few patterns:

The school applies a lower code than the diagnosis warrants. A child with a neuropsychological diagnosis of ADHD combined type plus a language processing disorder may be assigned Code 10 (at-risk) rather than Code 34 (language disorder), because the school's psychologist doesn't consider the presentation severe enough. Parents who disagree need to present contradicting private professional reports and request formal reconsideration.

The diagnosis arrives late, delaying the code. With public wait times for psychoeducational evaluations stretching 6 to 24 months, many children spend years in the "at-risk" category waiting for the formal assessment that would justify a higher code. Private evaluations — which cost between $710 and $1,750 for a comprehensive neuropsychological assessment — can bypass this wait, but they must be formally acknowledged by the school team when developing the PI.

The code is assigned but services aren't delivered. Code designation creates an entitlement to services, but the specific services must still be negotiated in the PI meeting. A code alone doesn't automatically produce a TES aide, specialized teaching hours, or assistive technology — those must be explicitly written into the PI.

The Quebec Special Ed Advocacy Playbook includes a reference section on EHDAA codes, the evaluation request letter citing LIP Articles 96.14 and 234, and a template for formally requesting that a private professional evaluation be incorporated into the PI planning process.

What to Do If Your Child Hasn't Been Formally Assessed

If your child is struggling but doesn't have a formal code, start by requesting a multidisciplinary evaluation in writing from the principal. Cite LIP Article 96.14 and Article 234. The school is required to assess the student's needs and adapt educational services accordingly — a formal code helps operationalize that, but the obligation to evaluate and respond exists regardless.

If the public evaluation queue is too long, consider a private assessment — particularly for speech-language or neuropsychological evaluation. Private clinicians recognized under the Quebec Professional Code produce evaluations that schools must formally consider when developing a PI, even if the school's own team hasn't conducted parallel testing.

Document every request, every timeline provided, and every delay. If the school fails to initiate an evaluation within a reasonable timeframe after your written request, that's the basis for a Protecteur de l'élève complaint.
