Paralympic classification

What classification is for

In most sport, the categories are obvious: weight, age, gender, distance. In Para sport the categories have to be constructed, because the thing being controlled for — the effect of an impairment on the specific tasks of a specific sport — is not directly measurable and differs between sports.

Classification is that construction. It answers three questions in order: does this athlete have an impairment that the system recognises; is that impairment severe enough to qualify for this sport; and, given how it affects the tasks this sport actually requires, who should they be racing against?

Nothing about a Para result is legible without it. A time in the 100 m means one thing in T11 and another in T64, and the two are not comparable — they are separate events. This page sets out the instrument that governs the whole system, because the answers below are not federation folklore: they are written down, and they changed in 2025.

The governing instrument, and why the edition matters

The controlling document is the IPC Classification Code. The current version is the third edition, in force from 1 January 2025, approved at an Extraordinary General Assembly on 17 May 2024 by 81 votes to 2. It supersedes the 2015 Code — and note that the word "Athlete" was dropped from the title, which is why the older name "IPC Athlete Classification Code" still appears in many federation rulebooks.^[1]

Three International Standards sit under it and are binding in the same way: Classification Personnel and Training; Intentional Misrepresentation; and Classification Data Protection.^[1]

The edition matters because the 2025 Code changed the answers to the most commonly asked questions about the system. Anything written from the 2015 Code will state the wrong number of impairments, the wrong number of assessment stages, and the wrong status codes. Several federations' own classification rulebooks — Para swimming's dates from August 2022, Para powerlifting's from January 2018 — still implement the older Code, which is a real and visible lag rather than a drafting quirk.^[2]

Seven eligible impairments, not ten

The most frequently repeated number in Para sport is ten: impaired muscle power, impaired passive range of movement, limb deficiency, leg length difference, short stature, hypertonia, ataxia, athetosis, vision impairment, intellectual impairment. That list is real — it is the impairment-type list federations use in their own rules, and every sport declares which of the ten it admits.

But the Code itself, at Article 8.1, groups them into seven Eligible Impairments: five physical, plus vision impairment, plus intellectual impairment. Both numbers are correct at different levels of the system, and confusing them is the single most common error in writing about classification.^[1]

An eligible impairment must be permanent and must result from an Underlying Health Condition. That requirement is what the new Stage 1 of the assessment exists to test.

Four stages

The 2025 Code runs assessment in four stages, in order. The first is new.

1. Underlying Health Condition Assessment. Does the athlete have a health condition capable of producing an eligible impairment? Federations must specify who conducts this for intellectual, physical and vision impairment respectively; it may be staff, classifiers, external experts or an outside body. Virtus, for instance, is formally recognised as a UHC Assessor for intellectual impairment. Passing gives the designation 'New (N)'.^[1] [3]
2. Eligible Impairment. Is the impairment one of the seven?
3. Minimum Impairment Criteria. Is it severe enough for this sport? MIC are sport-specific by design — an impairment sufficient for one sport may not be sufficient for another, and that is not an inconsistency but the point. Failing gives a 'Not Eligible' designation.
4. Sport Class and Sport Class Status. Which class, and how stable is it?

Article 18.3.1 controls what the panel may look at: it must "base its assessment solely on the extent to which the Athlete's Eligible Impairment(s) impact(s) their ability to execute the specific tasks and activities fundamental to the sport." The comment adds the discipline that makes the system workable — the panel must distinguish factors such as fitness level and technical proficiency, which are not to affect the class.^[1]

Assessment is in person, and other than observation in competition, in a controlled non-competitive environment allowing repeated observation. Where equipment is permitted, the athlete is assessed using the equipment they will race with, and the assessment must consider its optimal use "whether an Athlete chooses to use it or not" — so a wheelchair athlete who declines permitted strapping and consequently sits poorly is not thereby moved to a different class.^[1]

Why the class codes look different in every sport

The Code does not prescribe letters or numbers. Article 18.2.2 leaves each federation to define its own sport classes, which is why the prefixes are federation conventions rather than a shared alphabet.^[1]

• Para athletics — T and F. T for track, jumps and frame running; F for throws. The tens digit encodes the impairment family and the units digit the degree of activity limitation, lower being more affected: 11–13 vision, 20 intellectual, 31–38 coordination, 40–41 short stature, 42–47 limb deficiency without prosthesis, 51–57 wheelchair racing and seated throws, 61–64 lower limb with prosthesis, 71–72 frame running.
• Para swimming — S, SB and SM. S for freestyle, butterfly and backstroke; SB for breaststroke; SM is expressly not a class but an entry index for the medley. A swimmer commonly holds different numbers for S and SB.
• Para cycling — H, T, C and B. Here the letter denotes the machine, not the impairment: handcycle, tricycle, bicycle, tandem.
• Para powerlifting — none. One sport class, divided only by gender and bodyweight.

Where a class is provisional pending observation in competition, it carries the tracking code 'OA' until the athlete has been observed at their first appearance in it.^[1]

Sport Class Status — the part that decides whether a result is stable

Article 20.1 defines it in a sentence: "A Sport Class Status indicates whether and when an Athlete will be required to undergo Classification in the future." There are four.^[1]

• Confirmed (C). The panel is satisfied the class is unlikely to change. No further classification is required, subject only to a federation protest, an accepted medical review, or a change to the classification system itself.
• Review at the Next Available Opportunity (R–NAO). The athlete must complete an evaluation session before competing again. It is automatic where the panel was a sole classifier or entirely of the athlete's own nationality, where a medical review has been accepted, or where a protest is live; it is discretionary where the athlete is borderline — narrowly meeting the MIC, or on the boundary between two classes.
• Review with a Fixed Review Date (R–FRD). A further session will be needed, but not this year or season. The date is typically no more than four years after the previous evaluation.
• Expired (E). Automatic on retirement, and available to federations where an athlete fails to be re-evaluated within a stated period. The athlete cannot compete until the federation's requirements are met.

For anyone reading a result, the practical reading is this. A performance set by an athlete whose status was C is the most stable form the system produces. R–NAO means the athlete was, by rule, due for re-evaluation before their next competition. None of these statuses invalidates a past result — the Code contains no provision retroactively voiding results on a status change. Only a finding of intentional misrepresentation does that.^[1]

Protest, appeal, and the door that closes

This is the part of the system most likely to surprise a reader coming from any other area of sports law.

A protest challenges a sport class. An appeal challenges a process. Article 40.1 draws the line: an appeal lies only where there was "a breach of the International Federation's rules during the Classification process" and that breach "could reasonably have caused" a wrong outcome.^[1]

An athlete can do neither on their own behalf. Article 42.2: "For the avoidance of doubt, an Athlete cannot make a Protest themselves. A Protest may only be made on behalf of the Athlete by one of the bodies listed" — a national or international federation. Article 48.2 says the same of appeals. Sport class status, 'Not Eligible' designations and 'Classification Not Completed' are not protestable at all.^[1]

The scope of an appeal is narrow by design, and the Code says why in terms: "the right to submit an Appeal must not be seen as an opportunity to simply dispute the opinion of the relevant experts. The Appeal Body will only review the process by which the decisions have been arrived at." Its remedy is limited to affirming or setting aside — Article 50.1 states expressly that it "does not have the power to modify, alter, or otherwise change" a class.^[1]

And then Article 50.4, unqualified: "The decision of the Appeal Body is final and not subject to any further appeal or challenge."^[1]

Each federation designates its own appeal body, operationally independent, drawn from a pool of at least three. The IPC operates a Board of Appeal of Classification that federations may adopt by agreement — it currently serves sixteen, including World Para Athletics, World Para Swimming, World Para Powerlifting, the UCI, World Archery, World Taekwondo, World Triathlon and IBSA — but adopting it is optional, not automatic.^[1] [4]

At the Games the door closes further still. The IPC's Paralympic Games Regulations put classification disputes arising during the Games under the authority of the federations and the IPC, "whose decision on these matters is final, non-appealable and enforceable," with each member waiving its right to go to any other court or tribunal. Classification is not merely outside the Court of Arbitration for Sport; it is outside external review.^[5]

Intentional misrepresentation

The Code treats deliberately misleading a classification panel as its most serious offence. Article 51.1 defines it as intentionally misleading a federation or its representatives "in relation to any aspect of Classification," or complicity in doing so — and Article 51.4.1 adds that a participant "does not need to know that their conduct will constitute a violation" for it to be intentional.^[1]

The enumerated examples are unusually concrete: forged medical documentation; deliberately underperforming during an evaluation; deliberately tiring oneself out beforehand; attending without the equipment intended for competition, or failing to disclose its intended use; failing to disclose medication, a medical device or implant — expressly including hearing aids and corrective lenses — or a medical procedure; giving false identity information or sending someone else; and failing to disclose a previous classification in another Para sport.^[1]

The sanctions, under the International Standard, are the only part of the system that reaches backwards. Misrepresentation in connection with a competition automatically disqualifies the results obtained there, with forfeiture of medals, points and prizes; other results from the date of the offence may be disqualified at the federation's discretion; and the default period of ineligibility is four years, extendable to a lifetime.^[6]

What the athlete actually holds, and what is public

There is no classification certificate. The words "certificate" and "licence" do not appear in the Code in that sense at all — "certification" is used only of classifiers.

What exists instead is a register kept by the federation. Article 36 requires every international federation to "maintain, publish, and keep up-to-date a 'Classification Master List'" carrying, for each athlete, at minimum: name, gender, year of birth, nationality, sport class and sport class status, any designations — including 'New', the three 'Not Eligible' designations, 'Classification Not Completed' and tracking codes such as 'OA' — and any current intentional-misrepresentation ineligibility with its duration and start date.^[1]

Article 36.2 is explicit about the form: "Publication must be accomplished at a minimum by placing the required information on a publicly-available website." So classifications are publicly searchable — but per federation, not centrally. There is no single cross-sport Paralympic classification database, and the lists are handled under the International Standard for Classification Data Protection. Consent is a live gate: Virtus states that its master list is public and that athletes "must give their consent or entry to competition may be withheld."^[1] [3]

For anyone establishing what an athlete competed as, that master-list entry is the document — dated, federation-issued, published, and created for a purpose other than proving anything about the athlete. The wider paperwork layer.
