IPC classification position stand
Classification exists to minimise the impact of eligible impairment on competition outcome, so trained athletes are not moved up a class (selective, not performance, classification)
Key Findings
The IPC Classification Code mandates evidence-based classification; the paper defines it (the system's purpose is stated unambiguously, and empirical evidence shows the class-assignment methods achieve that purpose) and gives guidelines for reaching it.
Purpose: every Paralympic classification system should state that it exists to promote participation by minimising the impact of eligible impairment types on the outcome of competition. The absence of such a purpose statement had been the main barrier to evidence-based systems.
Sport uses two kinds of classification: performance classification and selective classification. Paralympic sport needs selective systems, so that athletes who improve through effective training are not moved into a class with less activity limitation, as they would be under performance classification.
To minimise the impact of impairment, each system should describe eligibility in terms of type and severity of impairment, and classify eligible impairments by the extent of activity limitation they cause — which requires objective, reliable measures of both impairment and activity limitation and research on their association in large, representative samples.The three-step wording used in the base (eligible impairment types → minimum impairment criteria → classes) is the full-text formulation of these requirements (not checked against the abstract).
Language should be consistent with the WHO International Classification of Functioning, Disability and Health. Weighting and aggregation of measures threaten the validity of current systems; the number of classes in a sport should not be driven by how many athletes it has at one time point.
Practical Application
The position stand's core: a class groups athletes by the activity limitation their impairment causes in that sport, deliberately so that training gains do not push an athlete up a class. Learn the athlete's sport-specific class before programming — it defines the peer group and realistic targets, and the coach's leverage is maximising trainable capacity within it.
Don't treat a diagnosis as the class: classification concerns activity limitation in a specific sport, so the same condition maps to different classes across sports; defer eligibility and allocation to official classifiers.
Not from this paper: autonomic status has been proposed as an additional classification input for SCI athletes (REF-636).
Limitations
2011 position stand; the IPC Code has evolved — treat specifics as framework, not current regulation; principles and a research agenda, not a validated allocation algorithm; no performance or training data.
How this entry was checked and changed
Why this level
regraded 2026-09-27 from B: governing-body position statement (rubric A: major consensus / position statement); it is a framework paper without trial data
Content correction 2026-09-27
Level B -> A per the 2026-09-26 rubric (governing-body position statement).
Added the abstract's content: evidence-based classification defined, selective vs performance classification, ICF language, validity threats from weighting/aggregation, class numbers not driven by athlete counts.
The "3 steps" formulation labelled as full text; "not a medical diagnosis" kept as the coaching reading of "activity limitation in the specific sport". Sport line normalised.
